The QMOD-HDMI RGB HDTV Modulator from Contemporary Research features one non-encrypted HDMI and one RGBHV/component inputs, making it suitable for sports, motion, and digital signage encoding. Dual hardware scalers accept content up to 1080p, shapes VGA signage for edge-to-edge presentation, and compensates for non-broadcast and PAL refresh rates. With ability to deliver two HD programs in one channel, the QMOD-HDMI 1.5 can also output the content as a multicast or unicast IPTV stream.
The modulator comes with dual-language SAP audio, easy front-panel setup, and alternate audio and NTSC video inputs. Web setup, monitoring, and firmware updates are available via USB and Ethernet ports. Two-across mounting offers up to four programs per rack space and the ability to mix models to handle HDMI, SDI, Component, RGBHV, and NTSC video sources. The version 2.3.4 update reduces end-to-end RF latency to 500 ms and adds RTP protocol for IP streaming.
