A ghost canceller includes a ghost cancelling circuit, waveform memories, a CPU, a training signal generating circuit, and a ghost variation detection circuit. By taking in GCR signals from the waveform memories into the CPU, synchronous addition and field sequence processing are effected, and they are transferred to the training signal generating circuit. The input video signal is changed over to the training signal to cancel ghosts, and when ghost variations are is not detected by the ghost variation detection circuit, the input video signal is fed into the ghost cancelling circuit, and is delivered as an output video signal.

A character multiplex broadcasting receiving apparatus is provided for reducing and displaying a plurality of character figure images including header information and text information. In the invention, to simultaneously display a plurality of character figure images, division signals are formed from a horizontal pulse, a vertical pulse, and a clock pulse (chrominance subcarrier frequency f.sub.sc .times.4) to designate areas on the CRT. Either and animation image (television image) or a character image to display character figure information is designated for each divided picture plane and a plurality of character figure images are simultaneously displayed.
