ENC3048 is broadcasting-level MPEG-2/MPEG-4 DVB standard digital video encoder which high reliability and advanced compressing arithmetic. Compression encoding process according to main-level master class (MP @ ML) and MPEG-4 Level 5 ASP,It provides one of the highest compression efficiencies in the mpeg2 broadcating, making it possible to transmit high quality video content at the lowest bandwidth possible. and audio encoding can support two audio PID, produces ASI and IP output data stream, in particular, channel 3 and 4, the output rate in the system without changing the dynamic adjustment of video bit rate to ensure error-free output.
