Description STi5211
1 Description
The STi5211 is a standard definition, 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 SD systems. With its enhanced performance
compared to the STi5202, the STi5211 includes both VC-1 and H.264 video decoders for
new, low bitrate applications.
The main platform target for the STi5211 is the DVB-S2 zapper. Alternatively, the device can
be used in a client box through IP over Ethernet, Multimedia over Coax Alliance (MoCA) or
WiFi.
