4to1 SD IPTV h.264 encoder 1.4 CVBS multiplexer to ASI,IP(spts/mpts) out 2.HD/SD 2xASI transcoder to 4spts 3.576I,480I
4 IN 1 H.264 Encoder for digital tv headend equipment
Model: ENC3140
ENC3140 4 to 1 H.264 SD encoder is broadcasting-level DVB standard encoder which high reliability and advanced compressing arithmetic. This encoder adopts the advanced circuit and embedded clock correct circuit, which reduce the signal programs needs and make sure to achieve excellent picture with very lower bitrate signals. It uses leading-edge compression technology H264/AVC and a variety of audio coding algorithm, It widely can be used to support IPTV,digital Cable/Terrestial/satellite standard,video surveillance applications. In addition, the ENC3140 provides one of the higher compression efficiencies in the broadcasting,making it possible to transmit high quality video content at the lower bandwidth.
Main Application:
Digital TV head-end system
IPTV,Over-the-air TV distance learning
Remote live Rebroadcasts and real-time transmission
Key Features:
Support for IP unicast and multicast network
Support the minimum bandwidth of 0.5Mbps,but in order to make the encoded image quality even approaching perfect,usually recommend customers to use in more than 1.0Mbps bandwidth
Support ASI input with up to 4 SPTS, and have the functions of multiplexing and transcoding(optional)
Support local and remote control network, and also support network upgrade
Each channel encoding SPTS has its own individual UDP-IP mapping (optional)
Variable PCR re-correcting for different network
Input video format (PAL/NTSC) adaptive selection,Embedded analog composite video, dual sound, stereo input
Built-in time base correction and video pre-processing
