Abstract

PROBLEM TO BE SOLVED: To reduce a printing cost without missing image data requiring emergency by immediately displaying the image data and a message at the display part of a television receiver when a FAX equipment receives the image data. SOLUTION: When an operator operates the operation part 18 of this video synthesizer 2 and sets the synthesizer 2 to a FAX display mode, a CPU 8 displays an operation mode to the display element of a display part 17. Then, the CPU 8 outputs information signals from a tuner part 12 to the television receiver 3 and reproduces video images and sound to the receiver 3. In the state, the CPU 8 monitors a modem part 16 at all times through a data bus 9 and an I/O interface 10 and judges whether or not the FAX is received by FAX control signals. When FAX reception is ended, the CPU 8 develops black and white dot data obtained by performing data expansion from code data stored in a memory part 14 as a sheet of image data in the memory part 14 and transfers them to a video signal preparation part 15. Then, the preparation part 15 synthesizes video signals from the dot data and outputs them to the receiver 3.
