New Set-Top Box Chip from STMicroelectronics Cuts Costs and Supports Latest Security Specifications

Geneva, -- STMicroelectronics, the world’s largest supplier of silicon chips for set-top boxes (STB)*, has announced the STi5107, a new MPEG decoder for standard definition TV, within the Company’s OMEGA family of STB solutions. Using the new device, manufacturers will be able to cut their total component cost and simplify board design and assembly, while offering enhanced security features.

The STi5107 is designed to address the requirements of the mainstream STB market, where it provides a unified, single-device platform for set-top boxes ranging from basic low-cost products up to MHP (Multimedia Home Platform) applications, for satellite, cable, and terrestrial services and plug-in TV modules.

ST currently supports the high-volume advanced-security STB market with the STi5517 and STi5100, which have been designed into a very high proportion of advanced security set-top boxes worldwide. The new chip offers a smooth migration path from designs based on these and other earlier-generation OMEGA devices, thanks to ST’s proprietary STAPI driver support and full reference software; STAPI is ST’s fully supported and documented programming interface, developed as a stable base on which to build applications, which allows software to be ported easily across product families. New designs are strongly supported by ST’s industry-leading development toolkit and by a broad range of third-party products.

The decoder supports the advanced security features required by all major conditional access (CA) suppliers The 200MHz clock speed of the embedded ST20 32-bit RISC CPU core – the most widely used CPU in the STB market – provides increased power for advanced applications and is fully compatible with all mainstream set-top box middleware.

“The STi5107 sets a new industry standard for advanced security, mass-market set-top boxes, reinforcing the outstanding success of the OMEGA family of MPEG2 decoders,” said Monica De Virgiliis, General Manager for ST’s Home Video Division. “It will bring further cost reductions for manufacturers while giving viewers the advanced features they now expect as standard, even in lower cost boxes.”

Overall performance is further increased by an integrated 2D graphics engine, which relieves the CPU of on-screen display (OSD) overhead and provides an enhanced experience for the TV viewer. This graphics sub-system is supported by an advanced ‘blitter’ -based display, which quickly implements bit-mapped graphics in hardware. Additional features provide the opportunity to extend the use of the chip to both alternative and more advanced platforms; features include DVB (Digital Video Broadcasting) descramblers, a low cost DVB-CI (Common Interface) to link it to a removable security module, and support for a single tuner DVR (Digital Video Recorder) for high quality time-shifting.

Like the other OMEGA devices, the STi5107 integrates a transport de-multiplex block, the ST20 32-bit CPU, an audio/video MPEG-2 decoder, a digital video encoder, advanced security features and the enhanced display and graphics features. DVB descramblers in the transport de-multiplex block and Macrovision copy protection allow it to be used in cost effective pay-TV services.

The STi5107 is built using ST’s low power, state-of-the-art technology and is offered in LQFP216 and PBGA324 packages. Samples are available now, with volume production starting early in Q1 2007. Pricing is $6 in 100k quantities.
