9.1.1General Description
This LCD TV F3-AS2 platform supports PC analog input up to XGA panel and supports TV (RF) for all China (/93) and AP (/79
/98) systems (PAL B/G, PAL D/K, PAL I, SECAM B/G, SECAM D/K, SECAM L, SECAM L1, NTSC M), YC, CVBS, Y Pb Pr, DVI
and PC signal input from SDTV to HDTV (480i/p, 576i/p, 720p, 1080i/p).
This platform LCD-TV uses MST96885LD (One Chip LCD-TV Controller) IC, which has embedded ADC for HD/Analog D-sub
input, ITU656/601 digital port for digital data input, SD ADC for CVBS/YC input, video decoder, audio decoder, TXT decoder,
Microcontroller, OSD engine and up/down scaler. For displaying, it will connect w/ TTL signal interface to TN VGA panel via FFC
cable.
MST96885LD is a high performance and fully integrated IC for multi-function LCD TV/Monitor with resolutions up to SXGA/WXGA.
It is configured with an integrated triple-ADC/PLL, an integrated DVI/HDCP/HDMI receiver, a multi-standard TV video and audio
decoder, a video de-interlacer, a scaling engine, the MStarACE-3 color engine, an on-screen display controller, an 8-bit MCU and
built-in output panel interface. With external frame buffer, 2-D video decoding and processing are fulfilled for high-quality TV
application. It supports de-interlaced full-screen video, frame rate conversion, aspect ratio conversion various video sources. To
further reduce system costs, the MST96885LD also integrates intelligent power management control capability for green-mode
requirements and spread-spectrum support for EMI management.
The MST96885LD enables consumer electronics manufactures to build low cost w/ high quality, feature-rich ATV. It embeds the
2D motion de-interlace to generate smooth picture quality for motion. 2D comb filter also recoveries high details for still picture.
The special color processing technology provides favorite and natural color for TV.
