9. IC3001 (RH-IXC354WJZZQ)
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 DTV.
Latest 3D+ comb filter 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 reduc-
tion and film mode detection are based on a unified memory technology.
Description:
• Stereo Decoder Audio Processing.
• Video Front-end 3D Comb filter, PC Connectivity.
• Motion Adaptive De-interlacing.
• Scaling, Display Processing and FPD Control.
• Unified Memory for Audio, Video and Text.
• Controlling, OSD and Text.
