ST FLI7510 iDTV片上系统(SoC)方案
ST 公司的FLI7510 是世界范围H.264/MPEG 译码器+ Faroudja 视频处理iDTV片上系统(SoC),包括有用于STB市场的STi710x数字/前端处理和多格式音/视频译码以及用于TV市场的Faroudja 视频/后端处理器,主要用于高性能和主流iDTV,以及多区域性DVB/ATSC/DTMB/ISDB.本文介绍FLI7510主要特性,方框图以及EU/US DTT + 有线iDTV 应用框图.
FLI7510: Worldwide H.264/MPEG decoder + Faroudja video processing iDTV SoC The FLI7510 is a revolutionary new iDTV SoC that integrates two highly successful, marketproven subsystems: STi710x digital/front-end processing and multi-format audio/video decoding from the STB market, and Faroudja video/back-end processing from the TV market. The FLI7510 is a high-performance, state-of-the-art SoC that can power DTT/cable/satellite/IPTV iDTV designs for worldwide deployment. From the software compatibility extending from the mature STi710x STAPI layer to the extensive video processing, tuning, and tools from Faroudja Labs, the FLI7510 is the ideal solution for addressing the next generation of iDTV design requirements.
The FLI7510 is the first in a family of scalable in performance and software compatible SoCs that address mainstream and performance segments of the iDTV market.The FLI7510 implements the latest generation of Faroudja Video Optimized technologies,which allow a high degree of customization for TV OEMs. Key technology improvements in this area include 14-bit color and contrast processing, upgraded sharpness, upgraded temporal noise reduction, and new MPEG noise reduction.
The FLI7510, with high performance CPU, A/V decode, graphics engine, and extensive network interface capability, enables TVs to deliver rich applications for convenient access to multimedia content, both from within the home, as well as from the web.
