4 in 1 Low bitrate mpeg2/mpeg4 h.264 encoder av to ip encoder with ASI re-multiplexed
Overview
ENC3144simultaneously encodes video/audio feeds as MPEG-2 SD 4:2:0 and MPEG-4 AVC (H.264) SD 4:2:0,using MPEG-1 Layer-II, LC AAC,HE AAC audio compression.designed to address this ever increasing demand for more video and audio services. With efficient bitrate utilization,high reliability and advanced compress arithmetic,it possible to transmit high quality video content at the lowest possible bandwidth. And produce ASI(MPTS Mode) and IP(SPTS/MPTS) output data streams.
Key Features
- Up to 4 channels composite and 4 pairs R/L analog audio per chassis
- Advanced MPEG-2 MP@ML4:2:0 and MPEG-4 AVC 4:2:0(H.264) ASIC technologies which offer broadcast video quality, generally for SD about 2.5mbps(MPEG-2),800kbps(H.264) for ultra-low bitrates
- simultaneous content encoding in MPEG-2 and MPEG-4 AVC formats in a variety of standard video resolutions
- MPEG-1 Layer,LC_AAC, HE_AAC audio encoding
- MPEG- TS over IP output
- In iptv applications,creation of multiple SPTS which can be multicast/unicast to 4 different ports or IP addresses.in DVB applications, set one MPTS to one IP address or port
- Range of encoding of video output: 0.25~7Mbps(H.264); 0.5~7Mbps(MPEG-2)
- NIT Insertion
- Audio sample rate: 32KHz, 44.1KHz, 48KHz
- System bitrate:2-40Mbps
- Screen ratio:16:9;4:3
- Management via embedded Web server, External SNMP and local front panel
- VBR/CBR Mode
- According to the user needs, can be equipped with ASI re-multiplexed optional
