Abstract
PURPOSE:To hold characters and patterns of cooking programs and so on for a long time to make it possible to read, reproduce, and display them arbitrarily, by using the pattern memory of the character broadcast receiver to store the normal TV broadcast picture. CONSTITUTION:The output of video detecting circuit 3 of the character broadcast receiver is led into waveform shaping circuit 10 and is subjected to waveform shaping by a prescribed level and is converted to a binary signal, and this binary signal is stored in digital memory 17 which can store one-field components. The picture dependent upon the output of circuit 10 is displayed on display device 7 during adjustment of the shaping level of circuit 10, and only the picture dependent upon the read output from memory 17 is switched and displayed on 7 by switching mixing circuit 5 after the completion of adjustment of the shaping level.
