Character broadcast receiving unit

Abstract

Abstract PURPOSE:To make it possible to avoid the disadvantage of impossibility of correct write and read to a main memory, by inserting a buffer memory between the main memory of the character information signal and the sampling circuit of the character multiple signal. CONSTITUTION:Buffer memory 16 is inserted between main memory 15 and sampling circuit 12 of the character multiple signal. By this constitution, the character broadcast program multiplexed with the broadcast signal of the B channel which is different from the A channel and is not synchronized with it can be projected onto the screen of CRT9 without any trouble when the TV program of the A channel is projected onto the screen of CRT9.
