Abstract

PURPOSE: To obtain the signal to display picture on television, by porocssing the signal reproduced from the recording media such as cassette tape and record disc to handle the frequency signal at around audio signal band.
CONSTITUTION: The instruction data and display data are included in the signal reproduced from cassette tape recorder and it is inputted to the microcomputer 3 via the demodulator. The content of digital signal is identified, the address is designated to the display RAM4' and color RAM5 to write in the content required for the display. When the address is designated to RAM4' and RAM5 in CPU3, the multiplexer 6 selects that the address bus A is connected to the bus B. The television screen is split into the blocks, 16×12=192, and each block consists of video elements of 8×8, one bit for display RAM4' is assigned to each video element, address is corresponded every 8 video elements arranged longitudinally, the block number is designated, the address is converted based on it, and the data being the content to be displayed is written in RAM.
