HD Video Conference & Presentation Room
System Design Solution
Two HD cameras will be installed on wall mounts, one above each display. The camera above the left monitor will be the primary camera used for recall of presets, including close-up shots of meeting participants. The camera above the right monitor will be used for wide cover shots of the room and meeting participants at the conference table.
Digital Matrix Switching and Signal ManagementThe Extron DXP 84 HDMI 8x4 matrix switcher will function as the heart of the system. HDMI input sources, whose source material or hardware requires the management of HDCP, will be switched alongside non-HDCP input sources. This configuration will provide efficient digital source selection, distribution, and image control for the display system. Only the appropriate sources will be routed to the PC input on the codec.
Extron DTP HDMI 301 and DTP DVI 301 Twisted Pair Transmitters and Receivers will be paired to extend DVI or HDMI video signals over a single shielded CAT 5e cable. This standardized and easily accessible infrastructure will provide the most effective method of conserving conduit space while preserving the integrity of the digital signals over considerable distances. The HD cameras, the HDMI input at the table, the HDMI input at the wall plate, and HDMI signal distribution to the displays will use this common cabling infrastructure. The DTP HDMI 301 supports DDC and HDCP which will provide reliable long distance DVI and HDMI signal distribution. The analog video and PC sources will be scaled and converted to DVI using an Extron DVS 304 DVI Video and RGB scaler.
Local audio signals will be embedded within the HDMI signals and routed using the DXP 84 HDMI matrix switcher. The Extron HAE 100 Audio De-Embedder will be used to extract audio from the DXP 84 HDMI outputs and send analog audio signals to the Extron DMP 64 ProDSP™ Digital Matrix Processor, which will also receive incoming audio from the codec. The DMP 64 will then send a combination of local and far-end audio to a single Extron XPA 1002 Stereo Power Amplifier. The XPA 1002 will then power the two wallmounted Extron SI 26 Surface Mount Speakers located on each side of the display system. Volume control of far-end and local audio, and the muting of microphones will be provided via the touchpanel and the control system. Audio from microphones will only be heard at the far end.
