Wellav UMH230 2-Channel MPEG-2 Standard Definition Video Encoder
2 Channel MPEG-2 SD Encoding
UMH230 Dual Channel MPEG Encoder
The Wellav UMH230 can support simultaneous MPEG-2 encoding of two programs in real time with independent ASI outputs or in one multiplexed output. It also supports composite input. With easy network management tool and affordable prices, this model is ideal for MPEG-2 encoding for both content distribution and redistribution.
Features
Two-channel 4:2:0 MPEG-2 SD encoding 1.5 Mbps to 15 Mbps DVB compliant MPEG-1 layer II audio encoding Four audio channels are analog input YCbCr, CVBS input Three independent ASI outputs including one multiplexed ASI output UMH230 supports MPEG-2 frame/field motion estimation and DCT Support editing of program/service provider name and PID setting TS stream PCR synchronization Managed via front panel or network management software (SNMP support)
