STB decoders with SVP technology

STMicroelectronics (ST) unveiled its first silicon devices to implement Secure Video Processor (SVP) technology, the next generation open specification for the protection of digital video content. "The SVP technology is coming to market at a key time when content protection has become a critical business issue," said Dr. Beth Erez, chairperson of SVP Alliance. "The need to provide robust rights management while allowing consumers maximum flexibility in their use of content has never been greater."

The STB5525 STB decoder, which is also ST's first single-chip solution to support dual TV and dual DVR (Digital Video Recorder) requirements in standard definition STBs, and the STB5524, which targets the growing DVR market, are intended for use across satellite, cable and terrestrial TV services.

Both the STB5525 and STB5524 devices offer a glue-less interface to ST's range of demodulator chips, enabling them to be used with a range of sources to provide a cost-effective solution for delivering digital content to two TV sets or two digital video recorders. They include a low cost SATA interface for connecting hard disk and recordable DVD drives, plus two 480Mbps USB2 ports for home networking and for the simple addition of peripherals.

The integrated CPU of the STB5525 and the STB5524 is a 300MHz ST231 core. According to the press release, the ST231 core is the fastest and most powerful ST processor to be used in an STB chip. The core is a member of the EEMBC-certified ST200 VLIW (Very Long Instruction Word) series which was designed for video and audio streaming in digital consumer applications, where high performance, low silicon costs and low power consumption must be combined with rapid development to ensure the minimum time-to-market. It executes up to four operations per clock cycle, achieving performance comparable to a RISC processor running at a significantly higher clock frequency while maintaining the low dynamic power consumption of its actual clock speed, added the company.

SVP technology

The SVP specification is maintained and promoted by the SVP Alliance, which is currently supported by more than 20 media and technology companies. The Alliance is working to achieve broad adoption of SVP content protection technology in digital home networks and consumer electronic devices such as digital televisions, STBs, DVRs and portable media players.

The STB5525 and STB5524 decoders will be available in sample quantities in Q3 2005, with volume production scheduled for Q1 2006. In volumes of 10,000 units, these two decoders are priced at $15 and $14, respectively.
