Features

Description
STI7108 is the next generation of HD, AVC set-top box decoder for satellite, cable, terrestrial and IP-STB markets. The STI7108 provides a solution for operators to specify a range of high-performance, MPEG2 / H.264 / VC-1 STBs. The STI7108 can be used with Zappers, IP clients, DVR standalone, and DVR server/home network STBs, especially where true 3D graphics is required.
