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 applications.

The main platform target for the STi7111 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.
