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.
