Product Overview
ASI Input Version
SFT3248 (SFT3248B) 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 6 tuner inputs to receive channels directly from satellite, or 6 ASI /8 IP inputs to receive digital channels. (SFT3248B is a simple version with 4 Tuners only or 4 ASI inputs only without IP input.) After trans-coding, it outputs MPTS & SPTS through the DATA port or ASI port.This trans-coder 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 your tuner 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.Features
