Abstract
A multimedia data encoding and decoding system capable of handling various types of data arranged in variable-size blocks. Frames of image, graphics and text data are supplied to a frame buffer. In response to an encoding command from a CPU, an MPEG encoder compresses the data from the frame buffer in accordance with the MPEG compression algorithm, and outputs to a texture buffer a variable-size data block that corresponds to the frame portion to be displayed. The size of the data block is set by the CPU, and may vary from one macroblock to, e.g., 22.times.16 macroblocks (one frame for MPEG-1). An MPEG decoder reads the variable-size data block from the texture buffer, decompresses and supplies it to a graphics engine that manipulates various type of data to create a picture to be displayed at a video monitor.
