Video Wall Display

Many of you may have heard about video wall display or maybe you even saw it a couple of times but didn’t notice at all.

What is video wall display? simply said : Multiple displays that can be used to create a large display. It combines several LCD / Plasma display into one large scale display.  They came in formed of  cube or stretched cube.

Video wall display (some call it matrix video wall) consists of LCD or Plasma display. It is recommended to use monitor or industrial grade products instead of consumer type products. What is the reason behind this?

Monitor type usually have slimmer bezel compare to TV’s bezel. With narrow bezel, it allows stylish images that are not blocked by the bezel. Currently they are several brand that have Plasma/ LCD monitor with narrow bezel (only 1,7cm thick). Thick bezel will obstruct the image and will provide gap between each display. This will happen if we used LCD TV or Plasma TV to build video wall display.

Besides narrow bezel, there’s also seamless bezel type. Seamless means that the bezel is so thin and reduced gap between each monitors in video wall form. The bezel only 7,3 mm – 6,7 mm. It’s very ideal for video wall display.

Other feature that included in most of plasma / LCD is built in wall matrix. With this feature you don’t need additional hardware or wall processor to construct a video wall display. Some manufacturer called this feature daisy chain link or build in video wall enlarger. This feature can only be used with RGB, DVI signal.

How do you build video wall with this feature? to put it simple, it works like this: Video wall with configurations of 2×2; output from source (RGB output) goes straight into input slot of display#1, then connect the signal from output of display#1 into input display#2, then connect again output from display#2 into input display#3 and so on until each monitor receives input signal. Then you will have to set each monitor their ID based on their position. Example: display#1 is set to be ID#1 and the position is on the upper left side and so on.

Next, what if you wanted to build video wall but you found out that the monitor you have didn’t have daisy chain / build in video wall enlarger? You will have additional hardware, Video Wall Processor/ Controller (VWP).

VWP has multiple outputs that will be connected into each correspondent monitor. The number of the outputs are depend on which configuration that you’re going to use. For example, 2×2 video wall means that the output from processor is 4x RGB/ DVI cables.

With VWP, each monitor can display different images/ contents or display single image in enlargement mode. This hardware is very powerful and quite expensive.

That will conclude my post of video wall display. I hope this will give better understanding about video wall.

Digital Signage System – How Does It Work?

On my previous post i’ve briefly explained about digital signage system (DSS). On this article, i would like to share about DSS schematics and workflow…

First, let’s take a look on DSS schematics

Basically, DSS consists of DS software, DS Players and Display Monitors. The image above show the schematics of single point/ single display of DSS.

DSS Software

This is the brain of DSS. The software divided into controller/ manager and player. Controller can be installed on desktop PC/ laptop. Usually installed on administrator’s PC and then the person in charge will be in charge for DSS operations.Some manufacturers called this software as controller or manager or author.

Step by step:

1. Set the DS zone  layout

How many zone are you going to use? Zone layout selection already installed and you just choose which one is suitable for your needs. On advance DSS software, you can design your own zone along with it details (number of zone, zone size, zone position, frame / without frame etc.).

2. Choose background template

On several DSS, they provide user to insert template background. If the features is not available, you can choose the pre-installed layout.

3. Upload contents

After choosing the zone layout and template, now user  can upload contents for DS such as video files, images, flash contents, photos and edit text for ticker. Upload various contents for each designated zone. Example: 1 video file, 1 image/photo, 1 flash animation and text for ticker. Total is 4 zones

4.  Set the schedule and duration

All the contents can be schedule based on time of the day, day of the week and so on. user can also setup the playback duration of each contents for each zone. With this, everything will be controlled from time to time. You can setup the playback list for your DSS for the whole week (24/7) and if you had any new contents to be played, all you have to do is just insert/ add and edit the playback schedule. This can be done on your controller / manage software which is installed on administrator PC.

5. Publish and Play

When you have finished with the contents management, then you can upload into DS player for playback. The playlist will be uploaded onto the player from user/ administrator PC via LAN/ WAN which runs inside TCP/IP network. Connection will be using ethernet cable from administrator PC to DS player (for wired network). you can also upload the playlist via wireless network. With this you will need a network and DS player with Wifi features. Some DSS also enable user to upload playlist via web. This feature is useful for DS player which located on different area or different part of town.

After being uploaded, DS player can now playback the digital signage into the monitor. Since user already setup the contents, schedule, duration and etc., all user have to do is just turn on the player and it will automatically playback the signage and play the contents based on schedule setting. Some software can also arrange the on/off date of DS player.

Contents changes based on schedule playlist

Digital Signage Player

The size of most DS player is quite compact, just like mini PC. But don’t let the look fool you, because this unit is designed to operate 24/7. Just like PC, DS player equipped with OS (windows or linux), storage, USB slot, ethernet port (for connection from administrator), RS-232C port for control, and video output to monitor. The video output can be VGA, DVI or even HDMI. There is also an audio output; 3.5mm jack (for VGA or DVI output type). Inside DS player already embedded DSS player software. This software is responsible for recognizing the uploaded contents from administrator and playback into the monitor. It is also possible to upload or edit content directly into DS player via USB. This option is useful when user unable to upload via network due to network trouble.

Digital Signage Player

The main reason why DS player is small because it will be easier for user to place it behind the monitor. Just mount the unit into monitor bracket. This will also save cost for cable usage from player into monitor, whether is VGA, DVI or HDMI cable.

I hope this article about digital signage will give more clearer information on how’s DSS works.

Until next time….

Flat Panel TV vs Flat Panel Monitor

Hi There…

This time i would like to share the differences between LCD TV and LCD Monitors.

First of all, LCD TVs are commonly for home entertainment (watching TV, movies, gaming purposes etc) and very easy to find at your local electronic stores. Meanwhile, LCD Monitors are commonly used for public display or for monitoring purposes such as display at mall, airport (to show flight schedule), commercial building or being used for digital signage displays. They called it monitor because they take out the TV tuner module. To watch TV broadcast you will have to buy external TV tuner. LCD monitor can be found at system integrator companies. Generally, LCD TVs are consumer goods and LCD monitors are considered as commercial grade / industrial goods.

Now let’s take short look at the differences;

Resolution

Basic resolution is almost the same between LCD TV and LCDM. The lowest resolution is 1366×768 WXGA and 1920×1080 Full HD. WXGA usually can be found on <42″ size while Full HD available on >42″ size. Currently, you can find Full HD resolution on 32″ size LCD TV.

Size

Both of LCD TV and LCDM available from 26″ – 65″ or for some brand available on larger size such as 70″ or 103″.

Key Specification

LCD TVs are intended for home usage, therefore their specifications are optimized for home usage. Contrast ratio for LCD TV is bigger than LCDM, because bigger contrast ratio will results in nice color reproduction, color depth & details, excellent black details etc, which is significant when you’re watching movies or playing games. LCDM is inferior in terms of contrast ratio, but they are more superior in brightness level. Since LCDm will be used on public areas and placed on semi outdoor/ indoor area. Higher brightness is important, because it will avoid color wash out from lighting or other light sources. LCDM are also equipped with anti glare coating to reduce glare either from bright light condition or reflection from sun light’s.

Connection

Most manufacturer put more input connections on LCD TV rather than LCDM. You can choose from analog video connection until multi digital video connections on the back panel of LCD TV. Some manufacturer equipped their product with 4x HDMI input and additional input terminal on the side panel of LCD TVs. Input connections for LCDM are more simple. Sometimes you have to buy additional input slot if you want to add more connectivity for LCDM. For example. some brand only came with 1x C-VBS, 1x Y/C and 1x VGA. If you want to connect component cable (YUV) or DVI/ HDMI cable, you will have to buy and install the input slot.

Key Features

Features for LCD TV are dedicated for entertainment pleasure. You can change color temp, gamma correction or use Picture in Picture feature. As for LCDM, the features are more complex and more advanced.

these are the key features of LCDM:

1. 24/7 operation support

The monitor can be operate for long hours / non stop operation fro commercial purposes.

2. Portrait or Landscape mode

PortraitDepending on the contents and information of the application, LCDM offers a choice of LCD monitors for landscape and portrait installations.

3. ID Setting via RS-232C connection

LCDMs are equipped with an RS-232C interface that allows them to be fully and easily controlled and monitored, with diagnostics, at a central location. You can remotely turn on and off an individual monitor, change video input and even scan the internal temperature of each monitor. User can also schedule the operation hour (on/off) of the monitors.

4. Video Matrix function

The mirror display mode lets you daisy chain several monitors together and have them all display the same image. There is also an enlarge display / matrix video wall mode.

video wall 2×2 configurations

Based on the brand, you set the video wall on various configuration such as 2×2, 3×3,5×5 or even in portrait mode video wall; 1×3,1×4 etc. Most LCDM already equipped with looping function or built in active matrix in order to construct video wall.

video wall 1×3 configurations

5. Narrow Bezel

The bezel for LCDM is very thin.With narrow bezel, transition gap between displays ensures a homogenous picture across the matrix. Below are the example of video wall with standard bezel and narrow bezel

video wall  from standard bezel’s LCDM

video wall from narrow bezel’s LCDM (small gap between each display)

Price

The prices for LCDM are more expensive than LCD TV. Even on the same size, the price gap could reach 30 % – 50%.

Built in PC or Built in Signage Player

Some manufacturer of LCDM already equipped their products with built in PC complete with the OS. With built in PC, you don’t need external PC to display your program or to show digital signage applications. It’s far more simple and make things easier for commercial usage. Meanwhile, there are LCD TV with built in PC features. Back then, LG released LCD TV with built in DVD player but didn’t sell well in the market. Most consumer prefer to use their external DVD player and laptop rather than built in products.

Interactive features

To fulfill interactive needs, LCDM equipped with touch screen module. Touch screen function usually used for directories, kiosk display or interactive wayfinding.

I hope this will give clearer picture between LCD TV and LCD monitor.

Feel free to drop a question about LCD monitor or video wall…

Helloww…

i would like to share some information regarding Digital Signage System. maybe some of you already heard about it and already saw it but didn’t have a clue about signage… At first, i also didn’t noticed about DSS. i thought it’s just a monitor who playback some advertorial or movie clips, video ads etc. Many places already implemented DSS, such as mall, hospital, hotel, restaurant, office building and so on. From there i started to wonder and got interested about DSS. Since then, i studied the concept and become more focus on DSS. here are some of my thoughts :

A. What is Digital Signage?

Digital signage is the industry term for using digital display technology such as LCD, Plasma, and LED displays to communicate with a target audience. Digital signage can be non-interactive and interactive through the use of touch screen. Digital signs break through the clutter and engage your audience. Digital signage allows anyone to become  a broadcaster.

Wherever you need to advertise, educate or inform customers, consumers, staff, students or partners, digital signage is a fast, reliable and simple way to get your message across to your specific target audience.

B. Features of DSS

- Screen Zone : divide the screen into several individual zone. usually, a single monitor divided into 4 zones and contain various sources such as movie, image, flash animation and running text.

- Auto Schedule : we can set the playlist the contents and set it on schedule per day, per week and set the duration for each contents.

- Custom Layout : some DSS provided a feature called custom layout. I means we can insert our own template, background color, fonts, insert logo etc.

- News Ticker : the bottom bar usually dedicated to show running text or text from RSS feed. mostly used for displaying welcome notes, additional info or news flash from web

- File Compatibility : it can play file from movies, HD movies, Jpeg, photos, powerpoint, web HTML, RSS feed, Flash contents

C. Benefits of DSS

The benefits of using DSS on various industrial sectors:

a. Increase products, services and company’s branding

b. Decreases perceived wait time and queue information

Rather than test your customer’s patience as they’re waiting for service, you can give them something to watch to take their mind off things. Show off  products and services on screen that differentiate you from the competition and also display queue information for visitors.

c. Grab customers attention

Dynamic digital ads will likely capture customers attention instead of static  ads

d. Strenghten employee’s motivation

reshape and redefine a company’s corporate culture into an environment that emphasizes ingenuity, awareness and teamwork that benefits the entire organization

e. Flexible in managing contents

Easy to add, remove or edit the contents. You can change the content anytime and broadcast immediately.

f. Multi informations to customer & internal communications

Provide detail informations to customer, regarding promotion, product features and other additional information. By displaying announcement, messages from the management level to workforce level

g. Creates potential new revenue opportunities if you want to get your vendors/ tenants to advertise on your network

D. Possible Contents

The contents on DSS :

¨Paid advertising by suppliers / partners

¨Products & services highlights

¨Meeting Schedule, events schedule

¨Local and national news

¨Greetings and broadcast messages

¨Directions and wayfinding

¨Company profile, achievements and peformance

You can find DSS on various sector such as; Mall/ theme park, amusement park, office building, hospital or healthcare services, restaurant or cafe, company or corporate, hospitality sector, education sector, retail sector and transportation sector.

On my next post, i will insert some pictures and some technical explanation on how’s DSS works

until then… cheeers

Integrated System

Hi there,

It’s been a while since my last post… i’ve been tied up with some integrated system job. Therefore i would like to share something about integrated system.

Integrated system is bringing together component subsystems into a whole and ensuring that  those subsystems function together. Interms of IT (information technology); Is the process of linking together different computing systems and   software applications physically or functionally. To put it simple in terms of office applications; Mix various video sources, electronical devices and route the outputs into display devices inside one system.

Integrated system provide simple things to control and manage the available equipments in the meeting room, boardroom etc.  The equipments involved inside an integrated system usually consists of:

• Video Displays : Projector with dedicated screen , FPD (flat panel display), Video Walldisplay etc.
• Audio Equipments : Speakers, Audio Mixer, Amplifier, Microphones
• Electronic Equipments : distribution Amplifier, Switchers, Matrix Switchers, Scalers etc
• Control System : Room Controller Panel, Touch Screen Controller.
• Conference Device : Audio Conference, Video Conference Devices.

This is an example how an integrated system works:

Projector is used for displaying presentation from PCs/ laptops, dvd player’s etc. and link with motorized screen. Plasma or LCD TVs is used to display image from video conference (if available) or used as secondary display.

As for the audio, usually we used audio mixer in order to receive audio inputs fromvarious sources (laptop, PC or dvd) and microphone input if available. With audio mixer we can adjust the gain level, balance, bass and effect for the audio. from audio mixer, we connect the output into power amplifier and then send the outputs to speaker devices. We can choose from wall speaker or ceiling speaker. Wall speaker provide more power rather than ceiling speaker. However, using ceiling speaker tends to caused feedback effect if we used a microphone during presentation or meeting. To eliminate feedback, we can add an equalizer to adjust the audio signal.

Next comes the electronic equipments. Electronic equipments consists of scaler, distribution amplifier, switcher and matrix switcher etc. It depends on how complex your system, then we can determine the suitable equipments for your meeting room. For example,  a scaler is used to upscale a resolution and convert the signal from video to computer/ HD signal. A distribution amplifier is used to clone and distribute an output into other displays, while a switcher is used to switch between input and show it into the display. The well known brands for electronics; Extron, Kramer, AVlink etc.

Control system is a device which can control all of the devices. It works like a universal remote control but with more advanced features. This control system can take over the control from A/V devices to lighting system and even the heat and air conditioning system. You can turn on and off the devices with a single touch of a button, and then you can still access the features from it, such as changing inputs, adjust volume or increase/ decrease temperature. For example; push one button then the projector turn on, screen rolls down, light turns off, air conditoner turns on and the audio devices turn on simultaneously. There are two types of control system; touch screen monitor or wall panel controller. The brands for control system are; Crestron, AMX, Cue etc.

Below is the example picture of meeting room with integrated system

With integrated system, everything will be more easy to manage and to control. Feel free to ask me a question about integrated system.

Dedicated Home Theater

A. Budget / Installation
Budget is one of crucial factor before you decided to build home theater system. Based on the budget you can choose the type of your projector, audio system, screen size or even your room’s design. If you had a tight budget or this is your first time with home theater system, i recommend you to pick entry level home theater projector (e.g: Infocus X10, Mitsubishi HC3800 etc). Those projectors are already came with native 1080p native resoultion. Showing full HD signal won’t be a problem!
Choosing entry level projector will save you extra budget. And that extra budget will help with the addition of such items as motorized drapery, floor lighting, and theater-style chairs to compliment your projector. For starters, you can contact your local installer, refer to home theater magazine or even try to design and setup your room acoustic all by yourself! It won’t be easy, but it’ll surely be fun though. Based on my experiences, tight budget home theater usually consists of: entry level projector, 16:9 screen (82”-92”), home theater in the box 5.1 system, integrated amplifier + video player, nice n cozy sofa, standard dimmer controller and acoustic panels. As for big budget home theater setup: high end projector (3-chip), anamorphic screen, processor and power amplifier, THX certified cinema speakers, theater style chairs with reclining features, room lighthing controller (crstron, lutron etc) and other fantastic accessories.

B. Screen/Projector
Let’s be clear about one thing, the default screen for home theater is 16:9 and not 4:3!
Screens vary in size and can be larger than eight feet (diagonally). Your screen can be as big as your home theater room dimensions will allow, making movies larger than life – literally. Plan your theater so the projector can sit at a relative distance (throw distance) from the screen to project the screen size you want. For example, a 106″ screen needs about 12 feet between the projector and screen. For more details regarding throwing distance, you can download projector throw distance calculator. It’s very easy to find that on the internet.
If cosmetics are a concern, consider a motorized, retractable screen, which can be set up to automatically extend and retract when you power your home theater projector on and off. These screens require special electrical and construction considerations.
Additionally, several home theater lineup of 1920×1080 widescreen projectors includes anamorphic lens support. Now you can showcase native 2.35:1 aspect movie content when combined with an anamorphic lens and see your HD movies in their ultra-wide image format. This is just as the movie director intended it to be viewed in theaters, but now you can view it in the comfort of your own personal home theater.  Some famous manufacturers for home theater screen: Stewart, Screen Research, Vutec, Draper etc.

C. Room Lighting
Light control is consider to be a big advantages to a home theater setup. With this you can make sure that there are no light leakage or minimize light leakage to your theater screen. This is very easy to xcontrol if your theater room didn’t have window at all. Or if your theater room comes with a window, you can install blackout shades or shutters either manual/motorized version.
Controlling the ambiance will create impact on the performance of your projector and the quality of your screen’s picture that will delight your audience. Technology in the projector, custom floor lighting, and dimmable lighting systems can help perfect the movie-going experience.
Some home theater’s have lighting control systems installed in the wall, either it’s a single control or multi control panel. With multi control panel , we can choose various setting of light conditions, depend on certain kind of ambiance that suitable for your pleasure. Example: romantic movies will have different light setting (more dark, to create romantic moments) compare to action movie. Even further, you can integrate that home theater lighting system to automation controller such as Crestron, AMX, Vantage etc., so your lights fade in and out automatically.

D. Sound
With dedicated home theater room, you don’t have to worry about the loud sound which came from your audio system. You can have your home theater sound-proofed to keep the movie audio in and the extra noise out. There are mutiple options of home theater – aduio equipment available in the market. From integrated amplifier or A/V receiver, processor, power amplifier, cinema speakers, subwoofers etc. A dedicated room means not having to worry about extra activity or traffic, so large speakers and sub woofers are available. They can be hidden in “false walls” behind transparent cloth, set in a decorative A/V cabinet, or built into the floor to save space for your seating. Choose your speaker wisely or consult with home theater consultants for the perfect choice of speakers, speaker size, speaker position. It is recommended to setup 5.1 system in smaller room or 7.1 system in larger room. For 7.1 system, use bi-polar surround speakers for more surround effects. Dedicated cinema speaker or THX certified speaker system is also recommended for more theater ambiance.
It is likely that room acoustics were already taken into consideration during construction so establishing the right sound will enhance your theater experience. Much like the screen, optimizing sound is a main priority in imitating the theater setting. The bigger the sound, the better.
For home theater newbies with tight budget, you can consider using these audio equipments: integrated amplifier (Yamaha, Denon A/V receiver), 5.1 home theater in the box system (4 satellite/ bookshelf speakers for front and surround, 1 center speaker and 1 subwoofer), cables and interconnects. For fanatics, enthusiast and high budget spending type, i recommend to use these equipments: high end audio processor/preamplifier, high end power amplifier (Mark Levinson, Krell etc), THX certified speakers with 15” or bigger subwoofer, cables and interconnects.

E. Furniture
After you decide on the projector, screen and sound, it is time to consider the home theater furniture and its arrangement. Choose from home theater seating, such as reclining chairs or authentic theater seats to extra equipment storage, such as dedicated cabinets or hidden closets. When arranging your home theater setup, be careful not to obstruct your view, to maintain easy access for guests entering and exiting, and especially to optimize comfort.
Several brand of theater furnitures for your considerations: Flexsteel, La-Z boyz etc.
It should all be specifically designed to meet your preferences. It’s your theater; you can design it any way you want. Fill the room with home theater seating and surround it with speakers, create a room with a theme, or imitate a real home theater setup by installing a ticket counter and a popcorn cart. It’s up to you.
Your Home Theater is going to bring the cinema home. You have a variety of choices, but the main objective here is combining authenticity and cinematic fun with unbeatable convenience.

Let’s make a home theater room shall we??

 

Cheers,

Basic Tips for Meeting Room Setup

On this posting, i would like to share some easy and basic tips for choosing the right equipment, easy setup for your meeting room. Please note that this tips are based on meeting room setup with Projector as the main display. Let’s take a look the basic tips step by step

1. Projector’s Type
Resolution: there are several type of resolution available in the market from SVGA, XGA, up until SXGA+. High resolution will get you sharper presentation images and will also cost you more. Most of the input for Projector came from PCs or laptops. Better use XGA based Projector since the native resolution of most laptops or PCs are XGA resolutions (1024×768 pixels). If the budget has no limitation then look for SXGA+ Projector.
Brightness: Brightness of a Projector is depend on room size and number of audience for the meeting. If you’re having presentation in a big and bright room with many audiences then you’ll have to use high lumens Projector (ex: 3000 – 4000 Lumens). As for small meeting room with few audiences (10-15 persons), 2500 Lumens should cover it.

Here’s a tricky question; what if the room size was big, bright but the number of seats available are only 10 -15 seats? Then you should use 3000/4000 Lumens Projector instead of 2500 lumens Projector. The brightness should accommodate the room size, ambient light and number of audience.

2. Screen
FYI, there are several types of projector screens; tripod, wall screen, and rear screen.For easy and convenient setup, choose wall screen. Since this is for presentation purposes, choose a 4:3 wall screen. But if you owned a WXGA Projector then you should consider 16:9 screen. The size of the screen should be determined based on room size, number of audience,viewing distance and Projector’s type. Large meeting room, many audiences, high brightness projector requires large wall screen such as 2×3 m – 3×4 m. The purpose of having big wall screen is to ensure all of the audience can see clearly the images shown on the screen. As for motorized screen can be connected to middle/ high end type Projectors via screen trigger control. Screen trigger means that when you turn on the Projector then the screen will automatically roll down, and when you turn it off the screen will roll up.

3. Installation Type
Choose fixed installation method for your Projector’s installation. In fixed installation you’ll have to install the projector on the ceiling; a ceiling bracket is require for this. There are two types of ceiling bracket: fixed and motorized ceiling. With motorized ceiling the Projector will be hidden inside the ceiling and it will come down from the ceiling when it’s turn on. There’s a wall switch to activate the motorized ceiling. All of the cables connected to the projector will stay hidden. The other method is dekstop installation. Just put the Projector on top of the cable, turn it on and then you’ll have your presentation. It’s very simple and you won’t need any bracket. The drawback of this method; sometimes you have to re-calibrate the zoom and focus level of the Projector everytime you turn it on and all of the cables will be visible and sometimes it will make the audience feel uncomfort due to hot air produced by the Projector, and less space on the table for taking notes during presentation.

4. Cables Connection
For common presentation you will have to prepared VGA/RGB cables, composite video/s-video or even component cable. Most presentations are showing input from PC/laptop via VGA cable or DVI/HDMI cable if youur PC/laptop already equipped with DVI/HDMI. My suggestion is to prepare VGA cable and video cables (composite,component – if the projector had component input). Video cables are needed to connect other input such as document camera, digital camera, video player and other devices with video output.The number of inputs which available on the back panel of Projector are very limited. Usually a medium type Projector will contains 2 x VGA, 1x composite, 1x s-video. What if you want to connect more inputs to the projector? Let’s say 3 x VGA, 2x composite etc? Then you will have to provide additional device such as presentation scaler, matrix switcher etc. This device can accommodate multiple inputs and only use single output into the projector.

5. Other Related Equipments
Additional equipments which can be useful for meeting room / presentation purposes are: presentation scaler, wall plate inputs, on floor inputs or control systems. Let me describe these additional equipment briefly.
Presentation scaler/ switcher: a device that can contains multiple video input, VGA input and then it scales the selected video signal to a computer graphics or HDTV output resolution. Therefore you will only used one cable from the scaler into projector instead of using plenty video cables, VGA cables from the sources into projector.
In Wall/ On Floor inputs terminal: Use custom inputs terminal and installed it above wall and on top of floor. This custom terminal provide video input and computer input. It works like a power socket but with video signal and computer signal. The output of this terminal goes to Projector.
Control System: an equipment that can take control the operations of every equipments inside the meeting room. It can operate Projector, video player, motorized ceiling, motorized screen etc and even lighting control. With a custom programming you can make all of the devices turn on with a push of single button.

hopefully these tips can give better understanding about meeting room setup… just drop a question if you need any suggestion. I’ll be happy to help you all

cheers!
