STMicroelectronics boosts performance and value for high-definition set-top boxes, with next-generation decoder IC

As the latest evolution of ST’s STi710x single-chip decoders supporting all required audio and video standards such as H.264, VC-1. MPEG2, and WM9, the STi7105 uses the same architecture enabling continuity and easy migration.

The STi7105 delivers cost and performance advantages for all set-top box markets, including basic zapper boxes, digital video recorders and media-server devices. By supporting the latest high-definition standards, as well as standard-definition formats such as AVS, the STi7105 delivers a low-cost, high-performance solution for products deployed in all geographic regions.

The STi7105 offers best-in-class power consumption and heat dissipation. In addition, a new DDR2 interface and unified 32-bit memory system allows designers to use cost-competitive DDR2 external memory to deliver maximum value for customers. Enhanced power management further extends the STi7105’s low-power credentials, helping end products to meet power-saving initiatives such as the International Energy Authority’s 1W Plan, which aims to save up to 1% of global CO2 emissions by targeting sub-1W standby power for all electronic products. At the same time, increased processing capability supports next-generation middleware and add-ins such as Flash media player and improved audio codecs. In addition an embedded SATA interface eases connection to hard-disk drives for DVR and PVR applications. Dual USB 2.0 interfaces enhance connectivity for use in media-server devices including in-car multimedia systems. The decoder also implements digital noise reduction, leading to optimal picture quality in a variety of applications and environments.

Enhanced processing capabilities in the STi7105 include an 800DMIPS CPU for control-plane tasks, as well as two VLIW DSPs to accelerate audio and video processing. A high-performance graphics processor with triple-source 2D blitter engine, compositor and 1080p output also ensures high graphics performance. Support for industry-standard operating systems includes Microsoft Windows CE, Linux and OS21.

As in ST’s current STi7109, comprehensive embedded security in the STi7105 includes DES, AES, and DVB descramblers, as well as support for digital rights management through Windows DRM 10 and Secure Video Processor (SVP) standards. Support for High Definition Multimedia Interface (HDMI) and High Definition Copy Protection (HDCP) also ensures secure connectivity to high-definition displays.
