Abstract

PURPOSE: To shorten the transmission time without causing deterioration in picture quality by selectively inserting a guard band signal into a picture information signal.
CONSTITUTION: A picture information section is uniformly divided and between the 3rd and the 6th block which are not adjoining each other, a signal into which a guard band signal is to be inserted is formed and sent. Such this signal is supplied from terminal 9 to synchronizing signal detection part 10 to detect a synchronizing signal, and a control signal is extracted by decoding part 11 and decoded. On the basis of the contents of the decoded control signal, picture processing part 12 ignores the guard band signal not before a block picture information signal following the 2nd one when two blocks with picture information continue, but before other picture information signal to store only the picture information signal in memory 13. Then, operation control part 14 exercises control over respective operations covering respective parts.
