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
