STi5211：Low-cost satellite set-top box decoder for Microsoft VC-1, H.264 and MPEG-2

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.
