　　FLI7515/25:Freeman Premier— H.264 iDTV SoC Integrated 120Hz FRC with 3DTV support

　　The Freeman Premier series of ICs are revolutionary new iDTV SoCs that integrate two highly successful, market-proven 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 Premier series are high-performance, state-of-the-art SoCs 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, Freeman Premier are ideal solutions for addressing the next generation of iDTV design requirements.

　　The Freeman Premier family of ICs are the latest in a family of scalable performance and software-compatible H.264 SoCs that address mainstream and performance segments of the iDTV market. Notably, they are single-chip, 120 Hz TV solutions incorporating Motion- Corrected Temporal Interpolation (MCTi) Faroudja technology. They utilize industry-leading vector estimation to interpolate in-between frames to correct film motion judder and panel motion blurring. Combining the artistic elements of film with the linear motion of video, Premier provides audiences with a uniquely enjoyable viewing experience.

　　Freeman Premier 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.

　　Furthermore, the Freeman Premier ICs support all connectivity requirements to 3D sources and all mandatory 3D formats defined in the HDMI 1.4a specification.

　　With their high performance CPU, A/V decode, graphics engine, motion judder reduction and motion blur removal features, and extensive network interface capability, Freeman Premier enables 3DTVs to deliver rich applications for convenient access to multimedia content, both from within the home, as well as from the web.
