MPEG DECODING CIRCUIT FOR DISPLAYING PICTURE AND NOTICE PICTURE

摘要

PROBLEM TO BE SOLVED: To decode and display a main picture and a notice picture by using a single MPEG decoder and a memory. ;SOLUTION: In a circuit 12, a memory 6 is connected to a bus 8 to be accessed from a bidirectional bus 8, an MEPG decoder 4 is connected to the bus 8 to read encoding and decoding data of the memory and an encoded data output part is arranged, which is connected to the bus along a first path 16, by which reading is performed from the memory data of a first picture. A first picture display circuit 10 is connected to the bus to permit its input part to read data written by a decoder from the memory, a decimeter circuit 14 and a second picture display circuit 18 are included, the decimeter circuit is connected to a part between the output part of the decoder and the bus along a second path to write the second picture data displayed by reduction in the memory and, then, a second picture display circuit is connected to the bus to read data written by the decimeter circuit from the memory.;COPYRIGHT: (C)2001,JPO
