A MULTIPLE FORMAT VIDEO SIGNAL PROCESSOR

摘要

A video decoder (10) capable of transcoding video data from various input formats to a predetermined output format is disclosed. Input data may be standard definition (NTSC or PAL) data or MPEG compressed data. Standard definition data are rearranged into block format to be compatible with the decoder's (10) single display processor (40). The display processor (40) includes a block-to-line converter (56, 58) and selectively processes and conveys either MPEG format data or non-MPEG format data to a display device. A block based memory (20) stores MPEG and non-MPEG pixel block data. The decoder is capable of receiving and displaying burst and non-continuous transmissions.
