Abstract

According to the present invention, a plurality of broadcast programs are simultaneously displayed on a single screen, thereby allowing viewers to select a channel by using a selective channel selection by scanning, unlike a sequential channel selection method using a remote controller or a manual channel input method when a channel is selected. It allows more convenient, faster and comparison of programs for a number of broadcast channels, allowing viewers to make efficient channel selection.

Description

Multichannel TV by scanning method {Multichannel TV by scanning}

10 is a process in which a frequency transmitted from a broadcasting station is input from a television or other receiver.

FIG. 20 is a device for outputting all input broadcast signals to a television screen or an external monitor, and is responsible for restoring all channels received.

FIG. 30 is a view for restoring only a specific channel among channels received by a device for outputting all the broadcast signals to a television screen or an external monitor.

40 is a place where copies of each channel screen are stored for all the received broadcasts.

50 is output through a multi tuner or a general tuner, and a plurality of channels are displayed on a television or an external monitor together with a brief description of each broadcast.

FIG. 60 is a part that is responsible for selecting and inputting various broadcasts displayed on a television screen with a touch screen or a remote control using a scanning method.

70 is a key for inputting a favorite channel in advance and watching one channel and selecting a key of "preferred" at the same time to display the pre-input channels on the screen to watch.

The present invention relates to a manufacturing method of a multi-tuner and a device or a set-top box, a TV, other monitors, and a remote controller implemented by a conventional tuner. In addition, the present invention belongs to the technical field of the present invention the concept of the multi-channel represented on the screen.

Currently, technology in this field shows that only one channel is displayed by one adjustment when selecting a broadcast, and only one broadcast is restored at the same time. The conventional technology is based on the fact that only a few broadcast channels existed in the past, and thus channel selection was possible only by simple numeric input or sequential input of channels. However, if you consider air broadcasting, cable broadcasting, satellite broadcasting, and internet broadcasting as well as future specialized broadcasting (IP TV, etc.), flooding more than 100 channels and assigning different channel numbers to the same broadcasting depending on the local broadcasting environment It is no longer possible to memorize the channel for a particular program and even when you select the desired station, you can select a lot of stations one by one (sequential selection causes the screen to switch and the space-time difference between the screen). In this process, it is common to search the entire broadcast channel.

The present invention allows a plurality of channels to be simultaneously displayed on one television screen or an external monitor (FIG. 50), and channel selection is possible on one screen by scanning, not by a numerical input method or a sequential channel movement method of a conventional remote controller. do. It is also possible to display different preferred channels while watching one channel, thereby facilitating movement between channels. The present invention allows a plurality of broadcasts to be broadcast simultaneously with the input of a power source to be displayed on one screen. You can select the channel you want by scanning method in one screen without memorizing or sequential screen movement once.

end. Multi-channel TV-A device or a method in which a plurality of channels are displayed on one television screen at the same time as power is input, may be represented as shown in FIG. 50.

I. Multi-tuner method-The signal input as shown in (Fig. 10) is restored after all broadcasts received through a device such as the multi-tuner or multi-tuner player of (Fig. 20) to enable the output, (Fig. 50) All broadcast channels received on the television screen or the external monitor are displayed on one screen (FIG. 50). The viewer can easily select the channels by the remote control or other control device of FIG. 60 through the screen in which several channels are simultaneously displayed on one screen (FIG. 50). The configuration scheme is essential for a multi tuner or a multi program player (an apparatus for converting one television to display multiple channels simultaneously on one screen-Fig. 20).

All. General Tuner Method-When newly adjusting or installing a channel of a television, the signal input in FIG. 10 is scanned through the tuner in FIG. 30 to scan one channel for broadcast programming. The image and the information of the corresponding broadcast are stored in the memory of FIG. 40. When the television is powered on, the images of all channels are outputted and displayed on the monitor as shown in FIG. 50, and the viewer selects the desired channel by the scanning method by the remote controller of FIG.

la. Remote control or device for channel selection without the need for numeric keys-Fig. 60

E. Preferred Channel Control System-After designating a favorite channel in advance, and watching one broadcast, select the "Preference" key in (Fig. 70). You can move directly to the channel you want.

More than 100 channels delivered by various broadcast media can be quickly reviewed for scanning and more efficient channel selection.

end. Rapid-Multiple channels are displayed on one screen, which reduces the time by selecting by scanning method when moving to other channels.

I. Convenience-Since multiple programs are displayed on one screen at the same time as power input, view many channels simultaneously and select channels. Channel selection by scanning method is also an example of convenience

All. Comparability-Multiple channels are displayed on one screen, allowing viewers to easily compare channels for easy selection

la. Simplicity-Remote control eliminates the need for the numeric keys on the remote control when selecting a channel. You can also easily move to other channels while watching the main channel.

hemp. Saving and safety-Channel selection of existing TVs results in shorter lifespan of power and monitors due to screen switching, but scanning method requires only one screen switching when selecting a desired channel, thus extending monitor life. Power saving effect.
