UMH230 MPEG-2 SD Encoder

The UMH230 is Wellav’s new real-time 2-channel MPEG-2 SD encoder, It can support simultaneous MPEG-2 encoding of two programs in real time with independent ASI outputs or in one multiplexed output. It also support 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
  • 4) YCbCr, CVBS input
  • Three independent ASI outputs including one multiplexed ASI output
  • Support 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)
