INTRODUCTIONS
REH2204 Four-Channel H.264 HD Encoder is designed especially for multiple channels of video and audio compression and processing. It works in high performances, ultra-low latency and low bit rates for DTV systems, by adopting rt compression technology of MPEG-4 AVC/H.264, and supporting resolution up to 1080P full HD. Audio compression is supported by MPEG-1 Layer II, while HE-AAC & LC-AAC are also available by option. Apart from 4*HDMI or 4*SDI, the device offers an external ASI input for multiplexing. After processing of encoding and multiplexing, it outputs TS by ASI and TSoIP(UDP/RTP) interfaces. The device is able to work on multiple channels of signals in effective way, making it widely used in digital TV head-end system, broadcasting, distribution and contribution systems.
