The VDP® 313xY is a video IC family of high-quality single-chip video processors. Modular design and a submicron technology allow the economic integration of features in all classes of TV sets. The VDP 313xY family is based on the VDP 31xxB including YCrCb inputs for DVD component signals.
The VDP 313xY includes complete video, display and deflection processing. All processing is done digitally, the video frontend and video backend are interfacing to the analog world. Most functions of the VDP can be controlled by software via I2C-Bus interface.

Family members
Video Processor Family
Each member of the family contains the entire video, display, and deflection processing for 4:3 and 16:9, 50/60 Hz TV sets. Its performance and flexibility allow the user to standardize his product development. Hardware and software applications can profit from the modularity, as well as manufacturing, systems support or maintenance.
The new VDP 313xY family is the next generation of Video and Deflection Processors. The main differences towards the VDP 31xxB family are
