摘要： 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.

摘要： A video signal processing apparatus is provided which can be used when a transmitted video signal is displayed on a screen or a CRT having an aspect ratio (e.g. 9:16) different from an aspect ration (e.g. 4:3) of the transmitted video signal. When the video signal is time-base-compressed and displayed on the screen or CRT, a memory is used to store the digitally converted video signal. The video signal is written into the memory every two scan periods and is read out of the memory every two scan periods, thereby executing a double-speed scan conversion and also enabling time-base-compression to be performed. Accordingly, an optimum display state of video signals of various aspect ratios can be obtained by a small number of memory elements.

摘要： A video theater system includes a video cassette recording at least a component video signal to which a copy preventive scheme has been applied; a video cassette recorder for reproducing the video cassette; a tuner and an antenna for receiving a signal transmitted via a satellite; a controller device for controlling the video cassette recorder and the tuner; means for releasing the copy preventive scheme; and a projector for projecting a video image from which the copy preventive scheme has been released. The copy preventive scheme is applied, while at least a synchronizing signal is retained, to a protected video signal at a point between dubbing of the master tape to the distribution tape after a video conversion and the second video cassette recorder. This copy preventive scheme is released by means of a device and circuit following a video cassette recorder used to reproduce the video signal in readiness for the projection thereof onto a screen.
