Contemporary Research QMOD-SDI 2 HD Modulator/Encoder

Contemporary Research previewed its new QMOD-SDI 2 HD Modulator/IPTV encoder at the NAB Show in April. The original QMOD-SDI was introduced at the 2009 NAB Show and it dramatically reduced the cost of distributing HD-SDI over RF coax. “The revolution continues with the QMOD-SDI 2, which has the ability to deliver two HD-SDI streams over RF and IPTV. It retails for $3,600, nearly half the cost per channel of the original QMOD-SDI,” says Contemporary Research President Scott Hetzler. The heart of the technology shift is a new dual-channel encoder with embedded 608/708 captioning as well as Line 21 data on the unit’s dual composite/CC inputs. Each of the two SDI inputs is matched by coax SPIDF and analog stereo audio inputs, so that audio can be added when it’s not embedded. Integral scaling can accept 3G SDI, 59.94/60Hz video as well as international 50Hz and 25Hz formats. An optional upgrade key adds the ability to cross-convert resolutions, such as scaling all input formats to 720p or 1080i. Embedded or SPDIF AC-3 audio will pass through to the channel, and stereo AES, PCM or analog audio will be converted to stereo AC-3. In addition, encoding supports dual-language audio channels. The unit’s 1G IP port also supports onboard web pages, setup, monitoring, and firmware updates.
