How to Change the Display of Your H.323 Video Conference Room System

Change the layout with these simple tips, which should work on virtually any system.


When using MIVNET Connect on a PC or MAC, there's a handy user interface that provides full control over display options. Select the most important video feed for you, detach it, make it full screen or slide it over to an auxiliary monitor, while watching all the other participants on your other computer monitor. You’re able to control a wide variety of display options.


However, when using MIVNET Connect on a Polycom, Cisco, or other H.323 IP device, the same user interface and features are not readily available. The display, by default, shows all video tiles and connections to the bridge in a grid with small windows.


Traditional systems like these continue to use decades old 'transcoded' displays to present meeting participants in a simple grid display. At the time this practice was developed, bandwidth was limited (or only available at premium prices), so using as little bandwidth as possible was key. The 'virtual machine' capabilities were also yet-to-be-invented at that time.


But now, with the advent of modern gaming and their underlying graphics capabilities, the world is a different place.


Although MIVNET Connect is designed to work with limited bandwidth and optimized conditions for each participant, the client also delivers advanced functionality, which provides a “Best Seat in the House” experience. Each user is able to see the parts of the meeting most important to them, instead of being forced into the standard template of traditional systems.


Nowadays, if you’re using an H.323 room system appliance, how can you change the way your videoconference is displayed?


By using a little-known control feature, H.323 participants can change the layout that is displayed. They can fill their layout with the video feeds that are important to them, just as if they were on a PC or MAC.


Once you have all videos endpoints in the meeting connected, follow these instructioons to customize your screen.


1. On some devices, you’ll need to toggle your remote to send DTMF tones.

  • Polycom: Press # to activate the keypad for DTMF tones
  • Tandberg: Press # to activate "Touch Tones"
  • Lifesize: Press to toggle between presets and DTMF mode
  • Sony: Press * to activate DTMF mode, Enter to exit (microphone will not be active in DTMF mode)
  • Aver: Press Far/Near button on remote control to toggle between camera presets and DTMF mode


2. Using the remote control keypad on your Polycom or other H.323 device:

  • Use buttons 2 and 8 to find the proper layout.
  • Use buttons 6 and 4 to rotate the video streams, one by one, until you find the video from the user you want to have on the screen.
  • If needed, use 5 to reset to the default settings.



This should work with any H.323 device that supports DTMF, including Polycom systems. We welcome your input and would be happy to share any additional tips you may have. Good luck and happy conferencing!
