Description FLI7540
1 Description
The FLI7540 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 FLI7540 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 FLI7540 is the ideal solution for
addressing the next generation of iDTV design requirements.
The FLI7540 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 FLI7540 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 FLI7540, 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.
Along with a high performance, dedicated CPU for customer applications, the FLI7540 is
equipped with 256 Kbyte of level 2 cache to deliver the smoothest experience of Internet TV
applications. In addition, FLI7540 accelerates 3D graphics with an industry-leading GPU for
OpenGL 2.0 and Flash 10 graphics and user interfaces.
ST's strong and extensive relationships with popular web and Internet TV service providers
give TV OEMs a fast ramp-up to deliver compelling value-add content to the living room.

2.3 3DTV/3D video
3D video is the ultimate entertainment experience to have at home. Bringing 3D to TV is
about supporting the proper connectivity to 3D sources and FLI7540 supports all the
connectivity options that are required.
● Supports 3D mandatory formats defined in HDMI 1.4b specification
● Supports Deep Color with mandatory 3D timings up to 12 bpc
● FLI7540 paired with FLI25xx improves 3D playback by increasing the frame rate per
eye, leading to the highest quality 3D TV possible through the following key advantages
– Improved 3D handling with 240 Hz output
– High-quality 3D video that can be used in conjunction with Faroudja’s Motion
Corrected Temporal Interpolation (MCTi™)
– With FLI25xx’s superior 240 Hz processing, the 3D video will be much brighter
and have significantly less “ghosting” artifacts
– Backlight scanning supported for motion blur reduction
– Improved artifact reduction with separate handling of Main video, and PIP plus
graphics
– Automatic detection of OSD from sources like STB
– Support for 3D OSD
– iDP Tx – Simpler and cheaper versus LVDS
