Contemporary Research QMOD-HDMI2 Dual-Channel RF or IPTV Encoder
The dual-channel QMOD-HDMI 2, with two non-encrypted HDMIinputs, sets a new standard for sports, motion and digital signage encoding.Dual hardware scalers accept content up to 1080p, shapes digital signage foredge-to-edge presentation, and compensates for non-broadcast and PAL refreshrates. Able to deliver two HD programs in one channel, the QMOD-HDMI 2 can alsooutput the content as an IPTV stream. Options include 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, with the abilityto mix models to handle HDMI, SDI, Component, RGBHV and NTSC video sources.Version 2.3.4 Update reduces end-to-end RF latency to 500 ms and adds RTPprotocol for IP streaming.
This unit includes a universal rack mount kit, which is acombination of the RK1 & RK2EZ that will allow you to mount the unit into a1RU or 2RU slot in your Rack right out of the box.
