MPEG decoding circuit displaying images and incrusted images

摘要

A circuit including a memory connected to be accessible from a bidirectional bus, an MPEG decoder connected to the bus to be able to read coded and decoded data in the memory, and having a decoded data output connected to the bus according to a first path to be able to read from the memory data of a first image, and a first image display circuit, an input of which is connected to the bus to read from the memory the data written by the decoder, which also includes a decimator circuit, connected between the output of the decoder and the bus according to a second path to be able to write into the memory data of a second image, and a second image display circuit connected to the bus to read from the memory the data written by the decimator circuit.
