applications CPU (450 MHz) 32-bit DDR1/DDR2 compatible local memory
interface Multi-stream, DVR capable transport stream
processing Extensive connectivity (dual USB hosts,
e-SATA, ethernet MAC/MII/RMII, MPX, and
PCI) Advance security and DRM support including
SVP, MS-DRM and DTCP-IP DVD data decryption
DescriptionThe STi7105 uses state of the art process
technology to provide an ultra low-cost, fully
featured HD AVC decoder IC. It is a highly
integrated system-on-chip suitable for STB
markets across all networks (cable/satellite/DTT/x-
DSL/IP) worldwide.
The STi7105 is targeted at the latest Operator and
CE manufacturer requirements for STBs which
utilize advanced HD decoding (H264/VC-
1/MPEG2), and which conform to DVB, ISMA,
ATIS-IIF , SCTE, DirecTV, ATSC, ARIB, CEA, ITU,
OpenCable and MSTV specifications.
Description STi71052/11
1 DescriptionThe STi7105 provides a solution for operators to specify a range of low-cost, high
performance HD STBs including low-cost Zappers, IP clients, Interactive STBs, DVR
standalone and DVR server/home network capable STBs, and with content delivery
possible using broadcast or broadband networks, or both (hybrid STBs). The STi7105 keeps
pace with the latest conditional access, DRM and trusted platform requirements of major
operators worldwide by incorporating the latest generation of advanced security features.
The STi7105 offers current users of STs growing family of advanced decoding ICs
enhancements in performance and features whilst reducing cost and time-to-market for the
next generation deployments.
