BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a television receiver, and in particular, a broadcast of a regular channel output on a full screen and a broadcast of subchannels output on one or more sub-screens at the same time during an auto-program channel setting or a manual channel setting process. A television receiver and a method capable of outputting the same.

Digital broadcasting includes not only digital satellite broadcasting but also digital cable broadcasting and digital terrestrial broadcasting. In a digital broadcasting receiver such as a set-top box for receiving the digital broadcasting, the original video is received by receiving a digital broadcasting signal of an MPEG transport stream. And restoring and processing the audio signal, and then transmitting and outputting the video and audio signal to a television receiver or the like so that a user can watch a desired broadcast program.

In general, automatic channel storage in television receivers allows each channel one by one for the channel region in which the signal may be present (ie, RF signals for channel numbers 2 to 69 and cables for channels 1 to 125). While tuning, it searches for how many channels the broadcast signal is loaded on and stores the result.The harmonic component of the broadcast signal channel broadcast signal according to the sensitivity of the tuner and the synchronization discrimination sensitivity of the microcomputer is stored in the memory. The current channel information is stored incorrectly in another channel. In order to solve this problem, Korean Patent Application No. 2000-0034545 proposes an automatic channel memory setting method of a television receiver to prevent duplicate broadcasting signals from being stored in multiple memories when automatic channel memory is set.

Briefly looking at the technique proposed by the domestic patent application invention, the first step of tuning the first channel when the automatic channel storage setting mode is switched; A second step of determining whether a broadcast signal is present in the tuned first channel of the first step; A third step of storing corresponding channel information when a broadcast signal exists in the first channel selected as a result of the determination of the second step; After storing the channel information of the first channel in the third step or if there is no broadcast signal in the first channel tuned in, the next channel is tuned and terminated if the tuned channel is larger than the last channel, and tuned if the channel is smaller than or equal to the last channel. Determining whether there is a broadcast signal in the received channel; As a result of the determination of the fourth step, if there is no broadcast signal in the tuned channel, it is fed back to the fourth step. If there is a broadcast signal, the current channel information is compared with the previously stored channel information, and the current channel information is stored accordingly. In a fifth step, the channel is skipped.

However, in the case of setting the automatic channel of the television receiver as described above, if the automatic channel is set in the initial state without the stored channel, the channel cannot be received during the automatic channel setting, and the automatic channel setting is completely performed. Since the channel can be received after the first time, it takes too much time to receive the channel from the initial state.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

1 is a block diagram of a television receiver for channel output in the channel setting process according to an embodiment of the present invention.

Referring to FIG. 1, the television receiver 100 of the present invention includes a tuner 101 for receiving a composite video signal of a broadcast transmitted from a broadcasting station and outputting an analog video signal and a sound signal, and for displaying the video signal. A screen 102, a speaker 103 for outputting a sound signal, an A / D converter 104 for converting an analog video signal output from the tuner 101 into a digital video signal, and an A / D converter ( The video processing unit 105 makes the digital image signal output from the 104 into a signal form suitable for the screen 102, and the audio processing unit makes the sound signal output from the tuner 101 into a signal suitable for the speaker 103 ( 106, an image processor 107 for outputting the video signal output from the video processor 105 to the screen 102, and a sound signal output from the audio processor 106 to be amplified and output to the speaker 103. And a amplifier 108.

The television receiver 100 of the present invention includes a storage unit 109 for storing channel information and the like, a control unit for automatic channel setting and manual channel setting, and a storage unit 109 for storing channels stored in the channel setting process. And a control unit 110 for outputting a video signal of a broadcast on a storage channel stored in the storage unit 109 on a sub-screen.

The tuner 101 receives broadcasts transmitted through a plurality of channels, and tunes a channel indicated by the controller 110 to output the broadcasts of the received channels, and comprises an analog video signal that forms a composite video signal of the broadcast. The sound signal is separated and output to the A / D converter 104 and the audio processing unit 106, respectively. Here, the tuner 101 receives and tunes channels stored by the controller 110, and one or more channels among the tuned channels are output on the screen 102 by the controller 110. When several channels are simultaneously output on the screen 102 as described above, only one channel is output on the full screen, that is, the main screen, and the other channels are output on the sub-screen displayed on one side of the main screen. However, even though a plurality of channels are simultaneously output on the screen 102, only the sound signal carried on one channel is output through the speaker 103, so that the tuner 101 is controlled by the control unit 110. Only the sound signal carried in one channel among the channels being output on 102 is tuned and output to the audio processor 106.

The screen 102 displays an image signal processed by the image processing unit 107, and outputs only an image signal loaded on one channel or simultaneously outputs an image loaded on a plurality of channels. In this case, only one channel is output on the main screen and the other channels are output on the sub screen. When the automatic channel setting is performed by the controller 110, a screen window indicating the automatic channel setting state is displayed on the screen 102, which is in the form of a picture in picture (PIP) or pop up form. Is output.

When a plurality of channels are simultaneously tuned through the tuner 101, the image processor 107 processes only the image signals loaded on one channel among the tuned channels under the control of the controller 110 to the screen 102. The video signal output on the other channel is processed as a sub picture and output to the screen 102. In addition, the image processing unit 107 is controlled by the controller 110 during the automatic channel setting process, and processes the screen window indicating the automatic channel setting state as a PIP screen or a pop-up screen and outputs it on the screen 102.

The storage unit 109 is a storage medium for storing various types of information, and may be implemented as a memory device such as RAM or EEPROM or a hard disk driver (HDD). In 109, information about channels stored in the automatic channel setting process is stored. The storage unit 109 stores various execution programs, for example, an execution program for executing channel tuning, an execution program for manual channel setting, an execution program for automatic channel setting, and the like. In other words, during the automatic channel setting or manual channel setting, an execution program for outputting a plurality of channels simultaneously on the main screen and one or more sub-screens is set, and the automatic channel setting is in progress at the initial state without the stored channel. An execution program that can output the channel stored in the middle on the screen 102 is set.

The controller 110 controls the automatic channel setting or the manual channel setting by executing the execution programs set in the storage unit 109, and controls the output of one or more channels in the channel setting process, which will be described in more detail as follows.

When the user instructs automatic channel setting using a remote controller or the like, the controller 110 stores a channel in which the broadcast is normally received among the channels received through the tuner 101 and stores the memory channel in the storage unit 109. . This automatic channel setting is performed for all channels that the television receiver 100 can receive.

As described above, when the user inputs the subchannel number using the remote controller while the automatic channel setting is in progress, the controller 110 outputs the video signal loaded on the subchannel to the subscreen.

When one or more subchannels are output on one or more sub-screens during the automatic channel setting process, if a user instructs the output of a sound signal carried on one subchannel using a remote controller, the controller 110 instructs the user. The tuner 101 is controlled to output the sub-channel sound signal to the speaker 103. At this time, the tuner 101 tunes the subchannel indicated by the controller 110 to the audio processor 106.

The channel output function of the controller 110 is similarly performed in the manual channel mode for setting a channel manually designated by the user.

A process of outputting one or more channels on the screen 102 in the channel setting process by the television receiver of the present invention having the above-described configuration and function will be described with reference to a flowchart.

2 is a flowchart illustrating a channel output method in a channel setting process of a television receiver according to an exemplary embodiment of the present invention, and illustrates an example of outputting one or more channels on the screen 102 in an automatic channel setting process.

Referring to FIG. 2, when the user instructs automatic channel setting using a remote controller or the like, the television receiver 100 sets an automatic channel setting mode for automatic channel setting (S201).

In the automatic channel setting mode, the television receiver 100 detects a channel in which the broadcast is normally received and stores the detected normal reception channel (S202). In this process, the television receiver 100 automatically changes the channel from the lowest numbered channel to the highest numbered channel, so that the broadcast of the constant channel that is outputted to the right screen of the screen 102 continues every time the channel is changed. Is changed. Here, the positive channel is a channel that is tuned to the tuner 101 during the automatic channel setting process and is temporarily output on the entire screen of the current screen 102, that is, the positive screen.

In such a state that automatic channel setting is in progress, the television receiver 100 determines whether one or more subchannels selected by the user are output on one or more sub-screens (S203), and if there is an output subchannel, It is determined whether a user command to output a sound signal carried on one subchannel among one or more subchannels is input through the remote controller (S204). As a result of the determination, if there is a user command, the television receiver 100 outputs a sound signal carried on the subchannel indicated by the user through the speaker 103 (S205).

In addition, when there is no sub-screen being outputted as a result of determination in the determination process (S203) or there is no command for outputting a sound signal as a result of determination in the determination process (S204), the television receiver 100 continues the automatic channel setting while continuing to set up the sub-channel. The standby state for the output is maintained and it is determined whether the subchannel number is input from the user (S206). If the subchannel number is not inputted as a result of the determination, the television receiver 100 maintains the standby state for the subchannel output while continuing the automatic channel setting process. In addition, since the user inputs the subchannel number using the remote controller, in order to implement the present invention, a button for inputting a subchannel number on the remote controller, that is, selects a subchannel number to be output on the subscreen in the automatic channel setting process. It would be desirable to additionally arrange a subchannel button to When the sub channel button is attached to the remote controller, the user can select a sub channel number to be output on the sub screen by pressing the sub channel button during the automatic channel setting process or the manual channel setting process.

If the subchannel number is input as a result of the determination in the determination process (S206), the television receiver 100 determines whether there is a subchannel currently being output on the subscreen (S207), and if there is no subchannel being output, it is shown in FIG. As described above, the sub-channel of the input number is output on the sub-screen, but only the video signal of the sub-channel is output (S208), and the process proceeds to the storage process of the normal receiving channel (S202) while the automatic channel setting is in progress.

As a result of the determination in the determination process S207, if there are subchannels being output, the television receiver 100 determines whether the number of subchannels currently being output on the sub-screen is smaller than the predetermined reference subchannel number, for example, the number of subchannels being output is three. If it is less than the predetermined number of reference subchannels (S209), the video signal carried on the subchannel of the input number is additionally output to the subscreen of the screen 102. In addition, although the present invention discloses three subchannels that can be output on the subscreen in the automatic channel setting process as shown in FIG. 3, the present invention is not limited thereto.

If the number of subchannels being output is equal to the predetermined reference subchannels in the determination process (S209), the television receiver 100 cuts the output of the subchannels which are selected first among the subchannels being output before. The video signal loaded on the sub-channel of the currently input number is additionally output on the sub-screen of the screen 102 (S210).

As described above, the technical features of the present invention for outputting one or more subchannels on one or more sub-screens and selectively outputting a sound signal carried on the subchannels are equally applicable to a manual channel setting process.

Although the technical spirit of the present invention has been described in detail according to the above-described preferred embodiment, it should be noted that the above-described embodiment is for the purpose of description and not of limitation. In addition, those skilled in the art will understand that various embodiments are possible within the scope of the technical idea of the present invention.

As described above, the present invention has the following effects by simultaneously outputting the broadcast of the main channel and the sub-channels output on one or more sub-screens during the channel setting process. .

First, the present invention outputs the broadcasts of the channels stored in the initial state of automatic channel setting in the absence of the channel in which the TV receiver is stored, and shortens the time required for the reception of the channels. Can be.

Secondly, the present invention simultaneously outputs a broadcast of a regular channel output on a full screen and a broadcast of subchannels output on one or more sub-screens while the TV receiver tunes a channel, thereby providing a multi-channel to the viewer during channel change. A broadcast may be provided.

Third, according to the present invention, in accordance with a viewer's instruction, a television receiver outputs broadcasts of a regular channel output on the full screen and subchannels output on one or more sub-screens at the same time. By selectively outputting the sub-channel sound signal, the broadcast service to the viewer can be extended.
