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.
