STi7108 is first high-definition, set-top-box decoder from STMicroelectronics to support for next-generation NDS VideoGuard security kernel and DVB-CSA3 descrambler system. It is, claims the company, the first set-top box IC to combine 3D graphics, Ethernet, USB and e-SATA interfaces to connect internet devices, DVR storage or external flash or hard-disk drives. The IC uses the ARM Mali-400 graphics processor. The NDS security kernel protects media content and operator services has increased levels of security with Control Word Protection and the ability to enable DRM technologies. The ICs also provide support for DVB-CSA3, the broadcast descrambler specifications licensed by ETSI designed to replace DVB-CSA2. Dual CPU host processors are linked to a 256K L2 cache for up to 3000 DMIPS performance. A 3D graphics engine supports 3D Electronic Program Guide, and enables advanced internet content and gaming on the set-top box. It is able to decode video in industry-standard formats, including H.264, MVC, MPEG2, VC-1 or WMV9 internet video, and MPEG4 part 2, up to high-definition resolutions 1080p 50/60 simultaneously with 1080i/720p picture-in-picture or mosaic formats. The device offers dual 32 or 16bit LMI DDR2/ DDR3 at 1066MHz. There are up to six transport streams, and HD 3DTV over HDMI 1.4 with HDCP copy protection.
