HDE-4S-QAM (MPEG-2 HD Encoder – 4xHD-SDI/4xComponent/Composite – 4xQAM) accepts up to four (4) high-definition (HD) programs from any of the following inputs: 4xHD-SDI, and 4xComponent/Composite. MPEG-2 encoded outputs are available in the following formats simultaneously: 4xQAM, 4xGigE (1000Base-T Ethernet), and 4xASI. To improve transport efficiency, the encoder allows operator to (i) assign one (1) to four (4) programs to each QAM output channel, and (ii) to individually turn on/off each of the four (4) adjacent QAM output channels. The encoder supports Dolby Digital and Closed Captioning (EIA-608 and EIA-708). It is also equipped with an Emergency Alert System (EAS) interface. 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.
