STMicroelectronics and Dahua Technology Ltd, China's cable and IPTV dual-mode STB provider, have successfully designed and manufactured an integrated digital-cable and IP set-top box (STB), making ST the first silicon supplier to provide single-chip dual-mode digital STB solutions for the China market. The box, which begins deployment in Hangzhou Province in August 2006, will enable consumers to enjoy a three-in-one digital media experience including digital-cable TV, video-on-demand and web browsing for a wider choice of information services and broadcast programmes.

At the heart of Dahua's design is a dedicated chip belonging to ST's STi7100 family of Advanced Video Codecs (AVC). This SoC solution integrates support for advanced high-definition H.264/MPEG4 AVC and MPEG4 P2 standard definition (SD) in addition to MPEG2 encoded video signals. These innovative single-chip HD/SD devices are the industry's first to enable the next generation of high-quality consumer video systems and broadcast services.

The STi7100's level of integration combines STB functions and multi-standard decoding circuitry onto a single piece of silicon minimising both design and production costs for STB makers. Produced using ST's state-of-the-art 90nm process technology, the STi7100 family devices provides a more cost-optimised HD/SD Cable/IP dual-mode interactive box in a single-chip design, paving the way for support of H.264 HD/SD streams with advanced codecs.

Compared with traditional TV delivery, IP set-top boxes provide an exciting interactive experience including Video on Demand (VoD) services that puts the audience in charge of selecting their favourite content according to their preferences, regardless of the programme schedule. With Dahua's STBs, consumers enjoy a wide variety of services including interactive games, SMS, e-commerce, VoIP, and video phone calls.

Dahua's chairman and general manager Mr. Zhu Giang Ming, said, "ST's cost-optimised single-chip solution, which includes a reference design with software kit coupled to their dedicated engineering support, have given us a unique solution and faster time-to-market."
