MPEG1 audio and video CD (VCD) decoder, intended for use in low-cost dedicated video CD players. When used with a 4 Mbit DRAM and a digital video encoder, the decoder adds the required functionality to a CD decoder to implement a low-cost video CD player capable of playing discs coded to version 2.0 of the video CD specification. The SAA2510 is an I2C-bus controlled chip and features serial data input in four common bus formats. SAA2510 provides digital video output in CCIR601 and 656 formats.

A bit-mapped on-screen display is provided and output video timing can be 525 lines/30 frames per second or 625 lines/25 frames per second. The SAA2510 is microcode programmable for feature enhancement.
