1 SME-1901 and SME-1911 Monitoring Streaming Media Encoders
1.1 Introduction
Designed for multi-format video/audio over IP in television facilities, the SME-1901 and SME-1911 are compact H.264
streaming encoders with 3G/HD/SD SDI input and optional Fiber connectivity; the SME-1901 also incorporates a 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 in a Densité 3 frame configuration. The SME-1901/SME-1911 are ideal for monitoring of core routers
over IP, with the SME-1901 also providing “fan-in” and “fan-out” distribution amplification.
1.2 Features
• Space and power efficient design offers up to 20 streaming encoders per frame (in Densité 3).
• High quality SDI distribution amplifier with up to six 3Gbps/HD/SD outputs (SME-1901).
• Highly robust performance with bypass relay protection (available with –R rears on SME-1901).
• Integrated fiber I/O using optional SFP module (available with –F rears).
• Audio encoding of two channels AAC or MPEG 1 layer II.
• Dolby Digital passed to the streaming output
• Effective management of embedded audio with:
 Selection of 2 channels out of 16 for encoding.
 Selection of 5.1 channels for downmix and encoding.
• Comprehensive metadata probing includes time code, closed caption (608, 708), teletext, AFD, and WSS.
• H.264 high profile video encoding up to level 4.0 for optimized monitoring.
• Full frame-rate encoding, with encoded resolutions from 128x96 up to 1080i/59.94/50, including 720p/59.94/50
standards.
• Flexible bandwidth management using fixed presets with bit rates from 250 kbps up to 5 Mbps.
• Dual resolution streaming allows simultaneous output of lower-quality proxy plus high-quality 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.
