Amphion Semiconductor Ltd has rolled out its high definition H.264/AVC hardware video decoder core for digital television applications including cable and satellite STBs, DVD players, home gateways and media centre PCs.

The CS7050 decoder core is fully compliant with ITU-T Recommendation H.264 ISO/IEC 14496-10 4 Advanced Video Coding Standard at Main Profile up to Level 4.1. This new standard, developed by the Moving Pictures Experts Group (MPEG), provides significant improvement over all previous video compression standards.

The company explained that in today's digital networks, limited transmission bandwidth and storage capacity, particularly for HD video, stress the demand for higher and higher levels of data compression. To address this, Amphion has developed a fully compliant hardware H.264 video decoder IP core which can be readily integrated into next generation multimillion gate SoC solutions.

"The development of hardware for H.264 is rooted squarely in Amphion's 'sweet spot'," commented Stephen Farson, VP of Engineering. "Much more than previous video compression standards, H.264 is exceedingly compute intensive."

The CS7050 is designed for ultra high performance, with support for a wide range of image resolutions, both HD and SD at Main Profile up to Level 4.1. Within the hardware, the computationally demanding operations of the H.264 algorithm are efficiently implemented. Firmware, running on an Amphion proprietary 32-bit embedded RISC controller, is used to perform high-level control and management operations and to provide flexibility to the solution.

For overall performance, the device is capable of decoding Main Profile video streams at resolutions up to 2K x 1K and at frame rates up to 30fps when clocked at 266MHz.
