<p>PROBLEM TO BE SOLVED: To delete and correct recorded character graphic information by multiplexing an input video code and an input character graphic code, so as to produce an input multiplex signal and to record it. SOLUTION: A received video signal 2 is compressed with a video coding circuit 31 into a video code 32. A character image selected by a character coding circuit 33 is coded with received character selection information 3, and a character code 34 is outputted. A multiplexer circuit 35 multiplexes the video code 32 and the character code 34 into one multiplex code 36, which is recorded in a recorder 8. At reproducing, a multiplex code 37 is read from the recorder 8 and given to a multiplexer circuit 38, where the code 37 is demultiplexed into a reproduced video code 39 and a reproduced character code 42. The reproduced video code 39 is given to a video reproduction (decoding) circuit 40, corresponding to the video coding circuit 31, and the reproduced character signal is given to a character reproduction (decoding) circuit 43 corresponding to the character coding circuit 33 and a reproduced video signal 41, and a reproduced character signal 44 are respectively obtained. Then the reproduced video signal 41 and the reproduced character signal 44 are given to a display compositing circuit 45, where they are composited, and the composited signal is displayed.</p> |
