IPC: H04N5/00
Filed: 1996-08-16
Abstract: PROBLEM TO BE SOLVED: To increase the convenient range of a television system for MPEG-2 signal through a simple means by deforming an MPEG-1 signal through a logic element combined with a microprocessor. SOLUTION: A logic element 14 deforms the MPEG-1 signal supplied from an input terminal 17 into signal form of simulating the MPEG-2 signal through the software of microprocessor 15. A demultiplexer 16 demultiplexes this deformed signal and supplies it to an audio decoder 18 and a video decoder 19. Thus, the convenient range of the television system for receiving the digital signal of MPEG-2 type and displaying an image can be increased by using the simple means. In this case, it is desirable to integrate the microprocessor 15, demultipliexer 16 and logic element 14 into the same integrated circuit.
