MPEG-2 HD Encoder
MPEG-2 HD Encoder


Product Code: BLT-HDE-8C-QAM


HDE-8C-QAM (MPEG-2 HD Encoder: 8xComponent/Composite to 4xQAM) accepts up to eight analog programs from any of the following inputs: 8xComponent and 8xComposite. The encoder is equipped with a spare input (9th input) to replace any one of the primary eight inputs in the event of a failure.

The encoder digitizes, MPEG-2 encodes each input into a high-definition stream, multiplexes the resulting eight streams, and then modulates them onto four adjacent QAM channels in the 54-1002 MHz range (CATV 2-158). Any one of the four QAM outputs is also available in ASI format.

The encoder supports Dolby® Digital audio encoding, and Closed Captioning (EIA-608) for each of the eight encoded programs. It is also equipped with an Emergency Alert System (EAS) interface consisting of a composite video and L/R audio program input. EAS triggering is via a 5-12 VDC input or dry contact closure available from most EAS receivers. 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 rear-panel 10/100Base-T Ethernet connection.
