Contemporary Research Introduces New QMOD HDTV Modulation Technology at InfoComm
Unit allows churches to combine signals from consumer HD cameras that use non-broadcast, 60-Hz refresh rates, along with some studio cameras using 3G HD-SDI.
Designed with the house of worship market in mind, Contemporary Research’s two new modulators are based on a totally new architecture. The company’s new QMOD 1.5 modulators start at single-channel operation and price, yet can be upgraded to two channels by entering an optional software key. The new, more advanced QMOD 2 products start out with two channels.In addition, the company’s new modulators support two video streams (RF and IP), two audio formats (AC-3 and AES stereo), two captioning options (708/608 and Line 21), and two MTS language programs for each channel. They all mount two-across in one rack space.According to a company announcement, the new QMOD 1/5 units feature unique flex encoding - the ability to convert non-ATSC video formats into a QAM cable channel. For example, some houses of worship want to use consumer HD cameras that use non-broadcast, 60-Hz refresh rates, along with some studio cameras that use 3G HD-SDI. While conventional SDI modulators cannot accept those signals, the new QMODs can. In addition, all QMODs will up-convert SD video to HD, and an optional upgrade key enables a full range of up- and down-conversion and scaling features.GigE Ethernet is included in all QMODs, supporting IPTV streaming, IP control and onboard web pages for setup, operation, monitoring and firmware updates, while screw terminals allow control for EAS broadcast. In addition, the new architecture offers future-proof operation that is open to adding any imaginable encoding methods and features from future firmware updates.The QMOD-SDI1.5 features HD-SDI (up to 3G), component, and composite/CC inputs, and supports SDI embedded, digital coax, optical and stereo audio.Designed for general and digital signage applications, the QMOD-HDMI1.5 includes HDMI (non-HDCP), RGBHV/component inputs. Dual composite/CC, stereo and coax audio inputs support single and dual-channel modes of operation.
