QMOD-SDI1.5
Overview
Employing a totally new HD encoding technology, the QMOD-SDI1.5 continues the QMODTM track record for
quality and innovation, setting a new benchmark for features and performance. In addition to standard SDI
resolutions, the QMOD-SDI can accept 3G SDI and 60/30 Hz feeds from prosumer SDI sources. Users can
upgrade operation for full scaling and dual-channel operation by entering optional upgrade key codes.
Sources
One HD-SDI input, 3G 1080p and 1080i/720p 59.94/60 Hz HD-SDI, and
SD-SDI 480i widescreen/4:3 video; also accepts embedded 608/708 captioning and Dolby AC-3 and AES audio
One Component input, 1080i, 720p, 480p, 480i video
One Composite video input for encoding, captioning, or EAS use
Stereo, optical and coax audio inputs
Encoding
Creates a high-definition 720p/1080i MPEG-2 stream for broadcast
Accepts pass-through AC-3 audio, converts stereo and PCM to stereo AC-3, can create dual-language audio for
each program
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
QSDI-Scale upgrade key allows full video up- and down-conversion
