とする2画面テレビジヨン装置。 Two field memories that alternately record each field signal as a frame memory in a two-screen television device that performs time axis compression by writing a small-screen video signal into a frame memory and then reading it out at a faster speed than the writing speed. 2. A two-screen television device, characterized in that the writing and reading timings of both field memories are shifted so that when one field memory is being read, the other field memory is being written.
