DATA PROCESSING APPARATUS FOR TRANSMITTING/RECEIVING COMPRESSED PIXEL DATA GROUPS VIA MULTIPLE DISPLAY PORTS OF DISPLAY INTERFACE AND RELATED DATA PROCESSING METHOD

摘要

A data processing apparatus includes a compression circuit, a rate controller, and an output interface. The compression circuit generates a plurality of compressed pixel data groups, each derived from applying a compression operation to pixel data of a pixel group, wherein the pixel group includes a portion of a plurality of pixels in a picture. The rate controller applies bit-rate control to each compression operation, wherein the rate controller adjusts the bit-rate control according to a position of each pixel boundary between different pixel groups. The output interface outputs the compressed pixel data groups via a plurality of display ports of a display interface, respectively.
