Product Description

Product Profile   



ENC***4H simultaneously encodes video/audio feeds as MPEG*2 SD 4:2:0 and MPEG*4 AVC (H.**4) 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.



With its standard IP interfaces, The ENC***4H provides significant operational advantages and cost benefits by connecting encoders, DCM Series and IP QAM modular and video IPTV server via a switched IP network rather than port-to-port ASI interconnects. As a result, any encoder anywhere in the network can efficiently be part of any multiplex, essentially creating a virtual headend.



Features        



*-Up to 4/8 channels composite and 4/8 pairs R/L analog audio per chassis

*-Advanced MPEG*2 *@********************VC 4:2:0 (H.**4) ASIC technologies which offer broadcast video quality, generally for SD, about 2.0mbps (MPEG*2), **0kbps (H.**4), 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_V1, V2 audio encoding
