IC3001: Main CPU / VIDEO PROCESSOR.
Part Number: VCT7993P-FA-A1-H000 SHARP Code: RH-IXC354WJZZQ
The VCT 77VWP (VCT-Pro) family is dedicated to high-quality FPD and double-scan TV sets. The memory and program ROM are integrated in
the IC. Modular design and deep submicron technology allow the integration of audio, video, Teletext, OSD, and controller-related functionalities.
They cover the whole range of fl at-panel display TVs. Each member of the IC family contains the entire audio, video, up-conversion processing for
4:3 and 16:9 50/60 Hz progressive or 100/120 Hz interlaced stereo TV sets plus the control/data interface for fl at-panel displays. The integrated
microcontroller supports a powerful OSD and graphics generator with integrated Teletext acquisition.
The VCT 77vwP family provides a front-end video-processing unit with 4 CVBS-Y/C or component inputs for HDTV, EDTV and SDTV. A VBI slicer,
support of 2000 pages of Teletext, and a 3-D comb fi lter for PAL and NTSC (in certain versions) are also available. The front-end unit further allows
processing an SD and an HD source in parallel, thus enabling PiP and PaP functionality. Motion-adaptive de-interlacing, temporal noise reduction,
and fi lm mode detection are based on a unifi ed memory technology. Post-scaling in the display-processing block ensures the desired output format.
Display processing is supported by an 8-bit 8051-compatible controller. By means of powerful alpha blending, the graphics mixer composes the
output image from following image layers: the video layer, the OSD layer and the pixel graphics layer. The audio part consists of a multi-standard
sound IF demodulator and a base-band processor supporting all desired sound features in this range.
The VCT-Pro front-end video processing unit offers 16 analog video inputs (CVBS/Y/C, RGB/Y Cr Cb) as well as digital interfaces for SDTV and
HDTV. Latest 3D+ comb fi lter generation provides highest performance for PAL/NTSC signals.
A VBI slicer, supporting up to 2000 pages of Teletext completes the analog video front end. 3D-motion-adaptive de-interlacing, temporal noise re-
duction and fi lm mode detection are based on a unifi ed memory technology.
