Description STi7111
1 Description
The STi7111 is an HD set-top box / full back-end processor for satellite set-top boxes,
compliant with ATSC, SMPTE VC-1, DVB-S2, DIRECTV, DCII and ARIB BS4 specifications.
It provides very high performance for low-cost HD systems. With enhanced performance
compared to the STi7109, it includes both VC-1 and H.264 video decoders for new, low
bitrate application s.
The main platform target for the STi71 11 is the DVB-S2 zapper. Optionally the device can be
used in a client box through IP over Ethernet, Multimedia over Coax Alliance (MoCA) or
WiFi.
