Description

The present invention relates to an input television signal input from an antenna of a color television receiver and other video equipment (for example, a video tape recorder, a video disc player, a television camera, a personal computer, etc.). ) Signal from 1 at the same time
The present invention relates to a television device adapted to display on one screen.

2. Description of the Related Art In recent years, the spread of video equipment has been remarkable, and an emphasis is placed on an input television signal which is connected to a television receiver and which is input from an antenna, and a television receiver which simultaneously displays on one screen. Means for projecting two different images at the same time with one television receiver have been tried for some time. For example, most of the screens are displayed by signals from other video devices, and a part of the display screen is tuned. It is possible to display a television signal that is input from the antenna input of the set receiver.

FIG. 2 shows an example of such a conventional two-screen display.
(1) is the television receiver main body, (2) is the main screen, (3) is the sub-screen, which is designed to be displayed together with the exciter (4).

The circuit configuration of the conventional television device as described above is
For example, as shown in FIG.

In FIG. 3, the signal input from the antenna (11) is a tuner (12), which receives a signal from the tuning circuit (1) in response to a command from a tuning switching command circuit (14) including a remote control transmitter.
3) is selected, passes through the video intermediate frequency circuit (15) and is demodulated to a video / audio signal, and the switching circuit (16) connected to this circuit (15) displays the demodulated video. -Audio signals and video / audio signals from other video equipment (17) can be added simultaneously. The switching circuit (16) is, for example, a switching command circuit (18) including a remote control transmitter.
, The color / video signal processing circuit (19), the synchronization circuit (20), using either one of the video and audio signals as the first signal.
And the color / video signal processing circuit (22), which is supplied in parallel to the audio circuit (21) and uses the other video / audio signal as a second signal to form a second signal processing circuit group, a synchronizing circuit (23), Audio circuit (24)
Are supplied in parallel. As a result, the first signal becomes the parent screen (2) shown in FIG. On the other hand, the second signal that has passed through the second color / video signal processing circuit (22) is an A / D conversion circuit.
It is digitized by (25) and written in the memory circuit (26). This writing is performed in accordance with the write command issued from the memory controller (27) with a clock corresponding to the phase of the synchronizing circuit (23). The written data is read out with a clock corresponding to the phase of the synchronizing circuit (20) of the main screen. The sub-screen frame color switching circuit (28) controlled by the command of the switching command circuit (18) controls the sub-screen frame circuit (29) to switch to the edge of the sub-screen (3) in FIG. A frame with a color indicating is formed and the digitized second video signal is stored in this frame, and the D / A conversion circuit (30) converts the framed signal into an analog signal. This analog signal is converted into a matrix by the two-screen creation circuit (31) together with the video signal that has passed through the color / video signal processing circuit (19),
It is displayed on the cathode ray tube (32) as two screens as shown in FIG. Note that (33) is the sub-screen creation circuit part described above.
(22) to (30) is a set, and (38) is a speaker.

In the above configuration, in order to sequentially select the antenna received signals, for example, the transmission signal of the sequential tuning start command circuit (34) consisting of a remote control device is connected to the sequential tuning means (35), and the tuning circuit (13 ), The television signals of the antenna input are sequentially tuned and displayed on the child screen, and the signals of the sequential tuning stop command circuit (36) consisting of a remote control are sequentially tuned to the tuning stop means (37). The channel selection can be stopped by connecting to the channel selection circuit (13) via ().

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in the sequential channel selection configuration as described above, a signal from another video device is displayed on the main screen and a signal of the antenna input selected on the sub screen is displayed. At this time, if you want to select a channel image other than the television signal input by the antenna and display it on the main screen, perform sequential channel selection by the channel selection start command circuit (34) and display the desired channel. When it is issued, the tuning stop command circuit (3
In 6), since the channel selection is stopped in sequence and the channel is moved to the main screen, there is a problem that it takes time and effort to replace the parent and child in the switching command circuit (18).

The present invention is a device configured such that a child screen is displayed on a part of the parent screen at the same time as described above, and the image of the parent screen and the image of the child screen can be interchanged. Provide a television device that allows you to easily see all channels of the television input signal of the antenna input on the child screen while looking at other video equipment and replace the selected desired channel with the parent screen in one operation. To do.

Means for Solving the Problems In order to solve the above problems, the television device of the present invention displays a child screen on a part of the parent screen at the same time,
And in a device configured to be able to switch the image of the main screen and the image of the sub screen, when the image of the antenna input is displayed on the other screen of the main screen and the sub screen,
A signal that is input from the antenna input is automatically sent in sequence, channel selection is stopped in the middle of channel selection, and the display is switched to the main screen to stop channel selection at the same time. Is.

Effect of the Invention With the above-described configuration, the present invention makes it possible to easily see all television signals from the antenna input on the child screen while watching the signals of other video equipment on the parent screen, and when the desired channel is found. , It is possible to replace the main screen with one operation.

Embodiment A television device according to an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a configuration example of the present invention, and the same blocks as in FIG. 3 are designated by the same reference numerals. In FIG. 1, the tuning circuit (13) is
