Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a television receiver that facilitates channel selection. [Conventional technology] In conventional television receivers, while receiving actual images,
When selecting a specific station from among multiple broadcast stations,
It was necessary to display the screen by changing the channel for each channel.

[Problem to be solved by the invention]

Therefore, when selecting one station from among an extremely large number of broadcasting stations, such as 24 channels in the C band and 32 channels in the Ku band, as in the United States, it is therefore complicated and inconvenient.

An object of the present invention is to provide a television receiver that allows easy selection of broadcast stations even when the number of broadcast stations increases. [Means for Solving the Problem] To this end, the present invention provides means for storing a plurality of reception channel images as still images, a means for displaying a plurality of still images stored in the storage means, and a method for displaying the plurality of still images stored in the storage means. and means for detecting selection of a specific image from the plurality of images displayed by the means.

〔Example〕

Examples of the present invention will be described below. Figure 1 is a block diagram of a television receiver according to one embodiment. 1 is a tuner that selects a station by inputting the signal received by the antenna; 2
1 is an IF amplifier that amplifies the intermediate frequency signal from the tuner 1, 3 is an audio detection amplification circuit, and 4 is a speaker. Further, 5 is a video detection circuit, 6 is a video processing circuit that processes the detected video signal so that it can be displayed, and 7 is a CRT for display.
, 8 is a transparent touch panel installed in front of the CRT 7. 9 is a control section consisting of a microcomputer that performs overall control, and in addition to selecting the tuner 1,
Take in the video signal from the video processing circuit 6 and reduce it to create a VR
It also operates by sequentially storing broadcast screens of a plurality of broadcast stations in AMIO and transmitting them to the video processing circuit 6.

Now, in this embodiment, the control section 9 is set to the channel selection mode by operating the operation section (not shown) and selecting the channel selection mode.

In this tuning mode, first, the control section 9 turns on the tuner.
The channels are sequentially selected from the youngest channel to the next, and the image data is fetched from the video processing circuit 6 to the control unit 9, and each image obtained at that time is the number n of channels existing in the reception band. Reduce to an area of 1/n. Then, the images reduced in this way are sequentially applied to VRA.
Write them side by side as still images on MIO, read out the contents in real time, send it to the video processing circuit 6, and write it to the CRT.
7.

As a result, for example, the total number of channels is 2, such as C band.
In the case of 4 channels, as shown in FIG. 2, C R'! is a still image of each channel. ” 7 display screen will be divided.

Therefore, when viewing the 24 channels of still images and selecting a desired image by touching it with a finger, the touch is detected by the touch panel 8 and taken into the control mn9, and the selected channel is detected.

Then, based on this detection result, the control section 9 selects the tuner 1 to the tuned channel.

In addition, by receiving a touch signal from the touch panel 8, the control unit 9 simultaneously cancels the channel selection mode and causes the video processing circuit 6 to process the manually input image from the video detection circuit 5 and send it to the CRT 7. Switch.

The split display screen has 24 channels in Figure 2, so it is divided into 6 channels horizontally and 4 channels vertically, but if this is accurately divided into a screen with vertical/horizontal = 374, the horizontal direction will be 1/6 Since the pixels and the vertical direction are reduced to 1/4 pixel (scanning line), and the reduction ratios are different, the image is displayed as an image that is longer than it actually is in the vertical direction.

To avoid this, you can create an image with the horizontal edges removed. Further, as shown in FIG. 3, the reduced screen may be the same both vertically and horizontally so that a blank space 71 remains.

In addition, in the above embodiment, when selecting a channel by touch, the image is checked and then a specific image is selected.
Display the channel on-screen in each split image,
You can also enable channel confirmation.

〔Effect of the invention〕

As described above, according to the present invention, it becomes possible to check a specific image and select a channel, which is extremely convenient.
