The QMOD-HDMI1.5 HDTV Modulator from Contemporary Research creates a 720p/1080i MPEG-2 stream for broadcasting applications. It accepts stereo, PCM, or pass-through AC-3 audio, and can create two MTS sub-channels for each input, supporting two languages each. Users can upgrade operation for digital signage scaling and dual-channel operation by entering optional upgrade key codes.

This modulator distributes channel over an on-site broadband cable system with adjustable output level to 29dBmV, compatible with all cable format broadband systems. It features up to 270 HD programs, 135 channels per system and delivers a fully active QAM 64/256 digital cable channel. It includes a compact switching power supply PS12 1.5 that easily fits in the plug space on a power strip.

Encoding

Creates a 720p/1080i MPEG-2 stream for broadcast
Accepts stereo, PCM, or pass-through AC-3 audio, can create two MTS sub-channels for each input, supporting two languages each
Includes captioning from Line 21 data on composite video inputs
Flex encoding downscales 1080p to 1080i, allows use of 720p/1080p 60Hz sources, and compensates for 60/30 Hz sources such as consumer HD cameras
QHDMI-Scale upgrade key adds scaling for many VGA resolutions, overscan compensation, and positioning
2-channel upgrade allows selection of inputs to create 2 HD channels
