The EN-31 is a two-channel HD/SD-SDI multi-CODEC capable contribution and distribution encoder supporting ATSC, DVB and ISDB applications via IP, ASI and optional DVB-S/S2 RF transport. It inherits Adtec’s broadcast quality compression, advanced feature set, performance and reliability in a dense two-channel platform targeted towards high value applications. The EN-31 allows for eight channels of audio per video service, VBI support, ASI Remux and easy-to-use interface. In addition to encoding MPEG 1 audio, the EN-31 adds support for Dolby Digital, AAC-LC and HE-AAC (v1 and v2) mixed mode audio encoding supporting stereo (2.0) and multi-channel surround (5.1) modes.
The EN-31 enables direct stream delivery to a CDN answering the need for over the top (OTT) video delivery via RTMP or on-board Zixi integration.
The EN-31 encodes two services multiplexed into an MPTS and concurrently transports services via ASI, IP and optional DVB-S/S2/S2X. The user has the ability to send MPTS or SPTS services to four IP destinations. The DVB-S/S2/S2X modulator supports both IF band and L-band with 10MHz L-Band insertion. Two or more units may be cascaded to increase channel density with the ASI remultiplex feature.
