SME-1901
Monitoring Streaming Media Encoder and Distribution Amplifier

Designed for multiformat video/audio over IP in television facilities, the SME-1901 is a compact H.264 streaming encoder with 3G/HD/SD SDI input and 1x6 SDI distribution amplifier. Two high profile H.264 streams are generated simultaneously from the SDI input. The main high resolution stream is ideal for in-house IPTV applications while the low resolution proxy targets streaming and display within a control system network. Both streams are full frame rate and provide high efficiency compression. It operates with a wide range of decoders, and offers exceptional space and power efficiency with up to 20 dual stream encoders per frame. The SME-1901 is ideal for monitoring of core routers over IP, while also providing "fan-in" and "fan-out" distribution amplification.

  • Space and power efficient design offers up to 20 streaming encoders per Densité 3 frame
  • High quality SDI distribution amplifier with up to six 3G/HD/SD outputs
  • Highly robust performance with bypass relay protection (available with -R rears)
  • Integrated fiber I/O using optional SFP module
  • Audio encoding of 2 channels of AAC or MPEG-1 Layer II
  • Dolby Digital can be passed to the streaming output
  • Effective management of embedded audio with:
    • Selection of 2 channel out of 16
    • Selection of 5.1 channel for downmix
  • Comprehensive metadata probing includes timecode, closed caption (608, 708), AFD, WSS and teletext
  • H.264 high profile video encoding up to level 4.0 for optimized bandwidth utilization
  • Full frame rate encoding, with encoded resolutions up to 1080i59.94/50, including 720p59.94/50 standards
  • Flexible bandwidth management using fixed presets from 128x96 at 256 Kb/s to 3G/HD at 8 Mb/s
  • Dual resolution streaming allows simultaneous output of lower resolution proxy plus high quality main stream
  • Operates with wide range of decoders, including STBs, PC clients and Grass Valley's iControl facility monitoring and Kaleido-IP multiviewers
  • Supports streaming of MPEG-TS over unicast or multicast using RTP/UDP
