The present invention relates to a method for outputting a broadcast program list in a digital broadcast receiver in which a broadcast screen of several channels is displayed on a screen as a thumbnail image and the focus is shifted to each broadcast.

In line with the recent digital trend, standardization of digital broadcasting is in full swing in the field of TV broadcasting. When you purchase a digital TV and install it for the first time or relocate your residence, it stores the channel information about the effective channels that can be received from the digital TV in the internal memory for network status. This is called automatic channel scanning. By storing the information in the internal memory of the digital TV, refer to the information stored above when operating the channel of the digital TV.

Digital TVs have more channels than analog TVs. Therefore, in the case of digital broadcasting, a large number of channels are available for viewers to select, whereas the program selection is very complicated and the number of channels is complicated, which makes the channel switching complicated.

For example, in the case of analog over-the-air broadcasting with 5 or more channels, you can select the desired channel by switching all the channels one by one.However, in the case of cable broadcasting that provides dozens of channels, the channel number can be directly selected to select the desired channel. I use the method of input.

In order to facilitate channel switching for digital TV users, a function of setting a plurality of preferred channels or an EPG function is provided.

However, the conventional method of storing channel numbers has a problem that it is difficult to store more than three or four channels that are frequently selected.

EPG is supposed to show all program guides for all channels, so when the number of channels is large, it is difficult for the user to see them at a glance.

In digital TV, a function of setting a plurality of preferred channels or an EPG function is provided. However, such a function is complicated or has many user-configured parts, which makes it difficult for general users to easily utilize.

In the case of EPG, it is inconvenient to check the channel number and program name only so that it is not possible to know which channel is currently being broadcast and what broadcasting is being performed.

In addition, you can see only one broadcast on a single screen, so you have to switch a lot of channels until you find a channel you want to watch, and you may forget which broadcasts are on which channels along the way.

An object of the present invention is to show a broadcast screen of multiple channels on a single screen, the user can know at a glance what kind of broadcasts are on different channels, and to move the focus on each broadcast to conveniently and conveniently watch the technology in real time To provide.

In order to achieve the above object, receiving and storing broadcast program list layout information from a user, and when a broadcast program list output command is received from a user, extract thumbnail images for each channel from the broadcast signal received through the tuner, and then layout information. Displaying a thumbnail image on a single screen according to the, and when a thumbnail image focus shift command is received from the user, and outputs a broadcast program list in the digital broadcast receiver, characterized in that for playing the broadcast of the channel corresponding to the thumbnail image shifted focus This is provided.

The broadcast of the channel corresponding to the thumbnail image whose focus is shifted is reproduced in the area, and the remaining thumbnail images are not reproduced in the displayed state.

After the thumbnail image is extracted from the broadcast signal received through the tuner at regular intervals and stored, the thumbnail image is displayed in accordance with preset layout information when a broadcast program list output command is received from the user.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram schematically illustrating a configuration of a digital broadcast receiver for outputting a program list as a thumbnail image according to an exemplary embodiment of the present invention.

Referring to the drawings, a digital broadcast receiver includes an RF receiver 100, a controller 110, a memory 120, a tuner 130, a demultiplexer 140, a decoder 150, an output 160, and an IDE interface. The unit 170 and the HDD 180 are included.

The RF receiving unit 100 receives the remote control code information selected by the user and transmits it to the control unit 110.

The controller 110 analyzes the remote control code transmitted from the RF receiver 100 and transmits remote control code analysis information to the corresponding device.

For example, if the remote control code interpretation information is a channel change request command, the controller 110 transmits a channel change request command to the tuner 130, and if the remote control code interpretation information is a broadcast program list output command, thumbnail images of various channel programs are displayed. The output is divided into a single screen.

That is, when the broadcast program list output command is received from the RF receiver, the controller 110 displays thumbnail images for each channel on a single screen according to layout information preset by the user.

The controller 110 extracts a broadcast program list in a text form from the broadcast signal received through the tuner 130 and receives the broadcast program list output command from the user and outputs the list together with the thumbnail image.

The controller 110 extracts a thumbnail image every predetermined time from the broadcast signal received through the tuner 130 and stores the thumbnail image in the internal memory.

When the thumbnail image selection information is provided from the user, the controller 110 reproduces a broadcast of a channel corresponding to the thumbnail image. That is, the user moves the focus to the desired thumbnail image by using the direction key of the remote controller, and then the broadcast of the channel corresponding to the thumbnail image to which the focus is moved is reproduced.

The controller 110 receives and stores broadcast program list layout information from a user.

The memory 120 includes a flash ROM for storing software such as an operating system and a DRAM for storing a virtual screen in the form of a bitmap that can be expressed on the output unit.

The tuner 130 receives a broadcast signal of a channel tuned under the control of the controller 110.

The demultiplexer 140 parses various information such as audio, video, and other data multiplexed on the broadcast signal supplied from the tuner 130.

The decoder 150 decodes the audio / video signal and the data signal obtained by parsing by the demultiplexer 140 and processes the decoded audio / video signal to be viewed and listened to.

The IDE interface unit 170 receives the TP data from the decoder 150 and stores the TP data in the HDD 180. When the playback request command is received, the IDE interface unit 170 receives the data stored in the HDD 290 through the control unit 110 through the decoder 150. To be sent).

The HDD 180 stores the TP data transmitted from the IDE interface unit 170 and stores a program selected according to a recording command of the user.

2 is a flowchart illustrating a method for outputting a broadcast program list in a digital broadcast receiver according to the present invention.

When the digital broadcast receiver receives a broadcast program list output command from the user (S200), the digital broadcast receiver displays thumbnail images for each channel according to layout information preset by the user (S202). At this time, the focus is focused on the channel currently being watched by the user, and the broadcast of the channel is reproduced, and the broadcast programs of the remaining channels are displayed as thumbnail images.

See FIG. 3 for a method of setting layout information.

The thumbnail image is captured and stored for each channel in the broadcast signal received through the tuner, and a detailed description of the method of capturing the thumbnail image will be described later with reference to FIG. 4.

For example, if the user sets the layout to 4 divisions, thumbnail images of 4 channels are displayed on the screen of the digital broadcasting receiver.

The user looks at the displayed screen and checks the program being broadcast in each channel. If there is a program to be watched, the user moves the focus to the desired thumbnail image by using the arrow keys. Then, the broadcast of the channel corresponding to the thumbnail image whose focus is shifted is reproduced in that state, and the remaining programs are displayed as it is.

After performing step 202, when the thumbnail image focus movement information is received from the user (S204), the digital broadcast receiver reproduces a broadcast of a channel corresponding to the thumbnail image whose focus has been shifted (S206).

That is, when the thumbnail image focus movement information is received from the user, the digital broadcast receiver recognizes the broadcast image corresponding to the thumbnail image whose focus has been shifted, selects the broadcast signal of the channel through the tuner 130, and decodes the output signal. Output through the unit 160.

At this time, the broadcast being played is played back in the area allocated to the user while being divided into a plurality of screens.

After performing step 206, if a full screen play command is input from the user (S208), the broadcast being played is displayed on the full screen (S210).

Through this, the screen of several channels can be checked on a single screen, and the desired program can be moved to the channel being broadcasted at once.

In addition, you can find out what kind of broadcasts you are doing on other channels, so you can easily and easily find the broadcasts you want.

3 is a flowchart illustrating a layout setting method in a digital broadcast receiver according to the present invention.

When the layout setting command is received from the user (S300), the digital broadcast receiver displays the layout setting screen (S302). The layout setting screen is as shown in FIG.

The user selects the desired layout division information from the displayed layout setting screen. For example, various layouts such as 4 divisions, 9 divisions, 10 divisions, 13 divisions, and 16 divisions are provided on the layout setting screen. If the user selects 4 divisions, 4 channels can be checked on one screen. If 16 divisions is selected, 16 channels can be checked on one screen.

When layout setting information is received from the user (S304), the digital broadcast receiver stores layout setting information selected by the user (S304). The stored layout setting information is used later to display thumbnail images as the user selects a program list output command.

4 is a flowchart illustrating a thumbnail image display method in a digital broadcast receiver according to the present invention.

The digital broadcast receiver captures and stores a thumbnail image for each channel in the broadcast signal received from the tuner (S400). The broadcast signal received by the tuner through the antenna includes a plurality of channels, and the digital broadcast receiver determines the program ID for each channel in the received broadcast signal before decoding the broadcast of the channel tuned by the user's channel selection. And capture thumbnail images for each program ID. Then, the captured thumbnail image is stored along with channel information and program ID.

When a broadcast program list output command is received from the user (S402), the digital broadcast receiver checks preset layout information (S404).

Then, the digital broadcast receiver divides the screen according to the checked layout information (S406), and displays thumbnail images for each channel as shown in FIG. 6 according to the number of divided screens (S408). At this time, the displayed thumbnail image is displayed based on the broadcast currently being watched by the user, and the focus thereof is the broadcast of the channel currently being watched.

According to another embodiment of the present invention, when a broadcast program list output command is received from a user, the digital broadcast receiver may divide a frame of the screen for each of the above layouts, capture a thumbnail image while switching channels, and display the thumbnail image in the set area.

The present invention is not limited to these embodiments, and many variations are possible by those skilled in the art within the spirit of the present invention.

According to the present invention, it is possible to check at a glance which broadcasts are performed on different channels in a digital broadcasting receiver, and there is an advantage of moving a desired channel quickly and easily.

In addition, according to the present invention there is an advantage that can be selected according to the user's taste by providing a variety of partitioning methods.

In addition, according to the present invention by watching the broadcast of multiple channels in real time, the user can check at a glance what kind of broadcasts are on multiple channels, and can easily and easily find the desired program to switch channels to maximize the visual effect There is an advantage.
