4 in 1 low bitrate MPEG-2 encoder
Overview
ENC3044is world’s most advanced MPEG-2 standard definition (SD) encoding platform, designed to address this ever increasing demand for more video and audio services. With high density,high reliability and advanced compress arithmetic,using MPEG-2 4:2:0 MP@ML and MPEG-4 Level 5 ASPvideo and MPEG-1 Layer-II audio compression. It provides one of the highest compression efficiencies in the mpeg2 broadcasting,making 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 Level 5 ASP video compression, specially the channel 1, 3 could be MPEG-4 video coding
- MPEG-2 TS over IP output
- In iptv applications,set the SPTS/IP mode to up to four separate IP address and ports,in DVB applications. set the MPTS/IP model to one IP
- Ultra-low series MPEG-2 Video encoding, generally, good image quality for SD is about 3mbps bitrate adjustable range: 1~7Mbps
- NIT Insertion
- Audio sample rate: 32KHz, 44.1KHz, 48KHz
- Channel 3 and 4 can support Dynamic Encoding to ensure error-free output.
- According to the user needs, can be equipped with ASI re-multiplexed optional
- Precise synchronization, timing control, AV delay
- ≤ ± 15ms, PCR jitter ≤ ± 37ns
- Video aspect ratio support: 4:3
- System output data rate range: 2~60Mbps
- Hi-Fi audio processing R / L channel, stereo input,
- input video format (PAL / NTSC) adaptive selection
- 7x188 bytes per udp packet
- Web or SNMP management
