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 * DVD quality in IP networks transmit video and audio encoding to support the minimum bandwidth of 0.5Mbps,but in order to make the encoded image quality even approaching perfect, we usually recommend customers to use in more than 1.0Mbps bandwidth * 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 * PID modifying and PSI/SI generating Inputs * Video: level: 4x CVBS 1.0Vp-p, Impendence: 75 Formats: NTSC/PAL * Audio: level: 8x R/L analog audio 2Vp-p, Impendence: 600 * 2 way ASI interface input multiplexing with other encoding channel(optional) * Connector:BNC Outputs * DVB Interface: 2x ASI , Comply to EN 50083-9 ASI Standard, BNC, 75 * Output Format: 188bytes * Output Rate: Single Encoder 0.5~15 Mbps * IP output: 100M Base-T Ethernet interface UDP output, Multicast or Unicast, support 1-4 SPTS or MPTS Encapsulation UDP-IP * Connector: BNC Video Encoding Features * Comply to the International standard:H.264/AVC Main Profile,Level 3.0 * Input Video Format:576i(PAL)¡ê¬480i(NTSC) * Spatial preprocessing * Scene change detection * Bit rate mode¡êoVBR/CBR Audio Encoding Features * Sampling Rates: 32KHz, 44.1KHz, 48KHz * Bit rate: 32, 64, 128, 192, 256, 384kbps * Encoding Format: MPEG I Layer I/II,CD quality * Quantization:24bit Managemnet * 10/100 M Base-T Ethernet, RJ45, SNMP and OTA * 6 keys: UP, DOWN, LEFT, RIGHT, ENTER and ESC * Front-Panel lcd configuration * Video/audio configuration * LED indicate light Environment * Comply to GB13837-92 & GB8898-88 standard * Power Supply: AC 90-250V 50/60Hz * Power consumption: 30 W * Operating temperature:-10 - 50C Packaged in standard cartons.
