EN-31 Encoder

Adtec Digital’s EN-31 is a dual channel, hardware-based distribution encoder with flexible transport options.
With a low power footprint, the EN-31 inherits Adtec’s broadcast quality compression, advanced feature set, service performance and reliability in a dense platform targeted towards high-value applications.

The EN-31 supports ASI remuxing, VBI processing and eight channels of audio encoding per video service. In addition to encoding MPEG 1 Layer 2 audio, the EN-31 also encodes Dolby Digital, AAC-LC and HE-AAC (v1/v2) mixed mode audio, including stereo (2.0) and multi-channel surround (5.1) modes.
Feature Highlights

  • Copper and CVBS Video Interfaces
  • Automatic SD and HD Detection
  • Eight Channels of Audio Encoding Via Embedded SDI and AES Inputs
  • Multiple Transport Stream over IP Protocols Including:
  •    RTP, UDP, RTMP and Zixi
  • ASI Input for External Transport Stream Multiplexing
  • MP1L2, DD, AAC-LC, HE-AAC (2.0 and 5.1)
Two or more units may be cascaded to increase channel density with the ASI remultiplex feature.

The EN-31 encodes two services, multiplexes them into an MPTS and concurrently transports it via ASI, IP, and optional RF.
The DVB-S/S2 capable modulator supports both IF-Band and L-Band with 10MHz L-Band insertion and Carrier ID.
Applications

  • Tier Two/Three Dedicated ASI, IP, and RF Contribution

  • DSNG

  • Private and MSO Cable Systems

  • ATSC Distribution

  • Campus, Hospitality, and Education markets

  • Contribution over IP

The EN-31 can be purchased with or without the integrated modulator and offers multiple feature keys for flexibility and future-proofing. Please contact your sales representative for more details about these features and how they can be enabled on your device.

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.
