EN-31 Encoder

The EN-31 is a two-channel HD/SD-SDI multi-CODEC capable distribution encoder supporting ATSC, DVB and ISDB applications via IP, ASI and DVB-S/S2 RF transport. The EN-31 allows for eight channels of audio per video service, includes VBI support, ASI Remux capability and an easy-to-use interface. In addition to encoding MPEG 1 audio, the EN-31 adds support for Dolby Digital, AAC-LC and AAC-HE (v1/v2) mixed mode audio encoding, supporting stereo (2.0) and multi-channel surround (5.1) modes.
The EN-31 inherits Adtec’s broadcast quality compression, advanced feature set, performance and reliability in a dense two-channel platform targeted towards high value applications.

EN-31 paired with the RD-30 is the perfect solution for Digital Satellite News Gathering, Point to Point contribution over IP and ATSC Distribution.

Digital Satellite News Gathering: With this solution, news operators can reliably encode up to two video feeds in MPEG2 or AVC and uplink in DVB-S/S2 with DVB-Carrier ID.

Point to Point IP: With robust IP deliver options, the EN-31 can encode up to two video services in AVC and deliver them over IP using UDP, SMPTE 2022 FEC or Zixi. The RD-30 can receive MPTS over IP and demultiplex and re-distribute over IP.

ATSC: The EN-31 supports MPEG2 HD encoding, AVC encoding for sub channels with Dolby Digital 5.1 or stereo options per video.
