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. Figure 1.
