ST 公司的STi1010是单片高性能片上系统（SoC）iDTV处理器，和世界上的数字电视标准如ATSC (美国), DVB (欧洲), ARIB (日本), DMB-TH (中国)以及PAL/SECAM/NTSC 模拟TV标准兼容。

STi1010采用32位RISC ST40 CPU具有 266 MHz 和 480 MIPS的性能，能提供高性能的视频处理如用于NTSC 和标准PAL的3D 梳状滤波器以及3D 降噪等。本文介绍STi1010的主要性能，方框图以及美国FPD iDTV方框图与欧洲 iDTV方框图。

STi1010 Single-chip worldwide iDTV processor

The STi1010 is a highly-integrated, high-performance system-on-chip iDTV processor
compliant with worldwide digital TV standards such as ATSC (US), DVB (Europe), ARIB
(Japan), DMB-TH (China) and PAL/SECAM/NTSC analog TV standards. The STi1010 provides a cost-optimized solution for iDTV (basic TV platform DTV150), with a minimum number of external components, 32-bit unified DDR2 memory interface for CPU, OSD, video.

       The STi1011 version permits low-cost iDTV implementation with a single 16-bit DDR2
memory interface. The STi1010 is able to receive TV signals from either analog or digital terrestrial transmission, cable tuner, satellite tuner, external audio/video sources such as DVD players, STB, PVR, PC, and so on. The STi1010 allows low-cost implementation of matrixed display integrated Digital TV, including HDTV display: LCD display, Plasma Display Panel (PDP), Rear Projection TV (RPTV) and Digital Light Processing (DLP) RPTV up to 1920 × 1080p resolution.

       The STi1010 provides Dual LVDS output, which can drive 18-bit, 24-bit or 30-bit flat panels, up to Full HD definition. Video output has programmable Line and Pixel output formats (1366 × 768 and 1920 × 1080 resolution included). The STi1010 also provides CVBS and YC output from a digital PAL/SECAM/NTSC encoder.

       The STi1010 supports the decoding and processing of Standard Definition (SD) and High Definition (HD), analog and digital video sources, and the decoding and processing of digital audio from stereo up to 5.1 audio channels.

       The STi1010 provides high performance video processing as follows:
       3D Comb filter for NTSC and PAL standards
       3D Noise reduction
       Automatic film mode detection: static picture, movie, video, 3:2, 2:2 pull-down detection and recovery. Automatic letter box detection, interlaced/progressive modes and scene change detection.

       3D motion adaptive pixel-based advanced deinterlacing with diagonal
       compensation:

       ST 3D contour sensitive Deinterlacer™ (CSDi)
       Flexible H and V scaling
       Image quality improvement: 10-bit resolution (up to 12-bit processing), automatic contrast enhancement, automatic color enhancement, 2D LTI, CTI, H and V peaking
       Picture In Picture (PIP) display
       The STi1010 supports high quality bitmap graphic display, Multi-plane On-Screen Display (OSD) generated at display panel resolution.
       The STi1010 product permits the development of Integrated Digital TV (iDTV) applications with services such as US Closed Caption, US Vchip, Teletext, DVB-subtitles, EPG, and middleware such as MHEG-5 and MHP. It supports conditional access for US (open cable CableCARD), Europe (DVB-CI) and Japan (ARIB Conditional access).
