Product Description


Dibview OTV-TR321 8 in 1 Transcoder is a professional bidirectional trans-coder to convert video between H.264 and MPEG-2 format and also to trans-code between HD and SD programs simultaneously. It is equipped with 4 tuner inputs to receive channels directly from satellite. And, each tuner is accompanied with a CAM/CI slot to descramble the encrypt content.


In addition, IP content can also be received and trans-coding processed. OTV-TR321 will at last output MPTS & SPTS through the DATA port (net port) or ASI port.

Dibview OTV-TR321 8 in 1 Transcoder supports advanced multiplexing and can effectively provide operators with real-time code rate switch and optimize the video with its high performance.


BISS function is now embedded to descramble your tuner input programs and CC function as well to transport your closed caption (or teletext). CC function has been embedded to transport your closed caption (or teletext).

OTV-TR321 can be easily managed through web NMS system, and has become an ideal solution for operator to provide high quality video trans-coding.
