HDE-2H-QAM (HD Encoder – 2xHDMI/YPbPr – QAM) accepts and auto-detects up to two (2) input streams in unencrypted HDMI and YPbPr (Component) formats. The encoder, when applicable, digitizes and MPEG-2 encodes each input into a high-definition stream (HD-1080i/720p), and then multiplexes the resulting two (2) streams into one (1) output in QAM format in the 5.75-864 MHz range (CATV channels T7-T14 and 2-135). Any combination of input multiplexing is allowed, for example, 2x HDMI, or (1xHDMI)+(1xYPbPr).
The encoder supports Dolby Digital AC-3 encoding and Closed Captioning, and is equipped with an EAS (Emergency Alert System) interface and an ancillary ASI output port. A front-panel RF test point allows for monitoring/testing of the QAM output without service interruption. Comprehensive remote monitoring and control is accomplished using any standard Web browser via a front-panel 10/100BaseT Ethernet connection.
