Abstract: A television receiver permits a sub-picture to be displayed on a sub-picture screen (Ss) inset within a main picture screen (Sm) on which a main picture is displayed. The receiver comprises common operation control means operable for selectively displaying on the sub-picture screen (Ss) a still picture taken from the main picture or the sub-picture. When the still picture is taken from the main picture (Figure 3B), a new still picture is displayed (Figures 3C, 3D) each time that the common operation control means is operated. However, when the still picture is taken from the sub-picture (Figure 3F), display of a still picture (Figures 3F, 3H) and display of a real moving picture (Figure 3G) are alternately carried out each time the common operation control means is operated.

Abstract: A picture-in-picture type television receiver in which a sub-picture screen is inset within a main picture screen to allow the same or different pictures to be simultaneously displayed and which includes a circuit for separately displaying the channel numbers of both the main and sub-picture screens momentarily whenever the picture content of the sub-picture screen is changed and whenever the picture content of the main picture is changed if the sub-picture is display.

Abstract: A picture-in-picture television receiver is so arranged that the compression ratio of a sub-picture discrimination character (4) displayed on a sub-picture screen (Ss) relative to a main picture discrimination character (12) displayed on a main picture screen (Sm) is selected to be smaller than that of the sub-picture (Ss) relative to the main picture (Sm), whereby the sub-picture discrimination character (4) is displayed in a relatively large, easier-to-see form.

Abstract: The apparatus for use in a television receiver of the kind controlled by a micro-computer (10) is intended for the situation in which power failures occur and specifically where instantaneous power failures occur and shortly thereafter the power is recovered, in which it is determined whether or not the time display data stored in a memory of the micro-computer is correct and, if so, such data is continued to be refreshed and is used for the time display, whereby a so-called backup circuit is simplified in construction, and even eliminated in some cases. The main television receiver control data are stored in a nonvolatile memory (24) when a power interruption occurs, but are only used to refresh the random access memory (13) of the micro-computer (10) in those instances where the power outage exists for a period of time long enough to erase the time display data retained in the random access memory (13), a condition that is determined by checking such time display data each time it is necessary to reset the central processing unit (11) of the micro-computer (10) in view of a drop in line voltage.

Abstract: According to the invention, there is provided a so-called picture-in-picture type television receiver in which a sub-picture screen is displayed within a main picture screen in a picture-in-picture fashion. When a picture based on a base band video signal from an external source such as a VTR, for example, is displayed on the sub-picture screen, if the sub-picture channel selecting means is then operated, the picture of a broadcast television channel is then automatically displayed on the sub-picture screen. This feature allows the omission of a video signal source switching means for the sub-picture, thus protecting the viewer from being confused when using the controls of the television receiver.
