Product description Designed for multi-format video/audio over IP in television facilities, the SME-1901 from Miranda is a compact H.264 streaming encoder with a 3G/HD/SD SDI input and 1x6 SDI distribution amplifier. It is compatible with the Miranda Densité 3 Frame (sold separately), which supports up to 20 units.
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.
The SME-1901 operates with a wide range of decoders, and offers exceptional space and power efficiency with up to 20 dual-stream encoders per frame. It is ideal for monitoring of core routers over IP, while also providing "fan-in" and "fan-out" distribution amplification. - Key Features
- - A space- and power-efficient design offers up to 20 streaming encoders per 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
