<p>PURPOSE:To share the decoding part of a reception side circuit and to simplify the title device by providing the other party separating buffer, a buffer control part to control the writing and reading of the other party separating buffer, and a frame memory selecting control part for the receiving side circuit. CONSTITUTION:For a transmission side circuit, a header signal to indicate the head of each image frame unit and information to indicate which is a transmission device for every packet are added. On the other hand, for the reception side circuit, the other party separating buffer 18 composed of plural buffers of respective image frame units is provided, and the writing and reading of the other party separating buffer 18 are controlled based on transmission equipment information from a packet decomposing part 16 and image frame header information detected before the information is inputted to the other party separating buffer 18. Further, one or plural frame memories 26, which are equipped as so many the frame memories equipped with the other party and store a signal in one frame before, can be switched by a frame memory selecting control part 30 by the output signal of a buffer control part 20. Thus, the decoding part can be shared.</p> |
