Abstract
PURPOSE: To simplify a circuit constitution by using a microcomputer to convert character pattern signals, which have control information added for every block and are sent in different transmission speeds by different transmission mediums, to character pattern signals to be displayed.
CONSTITUTION: Character pattern data and clocks are reproduced from character pattern information, which are transmitted through telephone line 1, by demodulator 4 and are outputted to terminals 5 and 6. In a character multiple broadcast, information transmitted from VIF11 has vertical and horizontal synchronizing signals separated by synchronizing branch circuit 14, and control information and data of character broadcast are outputted to terminal 17 by sampling gate generation circuit 15 and AND circuit 16. Then, the chrominance subcarrier is reproduced by color synchronization circuit 19 and is supplied to clock generation circuit 20 to generate clock signals to sample character signals and output them to terminals 17 and 18. These signals are converted to character pattern signals displayed on CRT31 through switching circuit 7 by the control of CPU35 of a microcomputer and are stored in RAM73 and are displayed on CRT31 through display signal generation circuit 28 and display signal switching circuit 29.
