QuestTel's B-ASI-IP-TSR is a professional bidirectional transcoder to convert video between H.264 and MPEG-2 format and also to transcode between HD and SD programs simultaneously (resolution scaling from HD to SD). It is equipped with 6 ASI inputs and an IP input to receive digital channels. After transcoding, it outputs MPTS & SPTS through the DATA port or ASI port. This transcoder supports advanced re-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 ASI and IP input programs and CC function as well to transport your closed caption (or teletext). It can be easily managed through web NMS system, and has become an ideal solution for operator to provide high quality video trans-coding.
