DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS
Below, exemplary embodiments will be described in detail with reference to the accompanying drawings. In describing exemplary embodiments, detailed description of relevant known functions or components may be omitted if it would obscure the description of the subject matter. In addition, the exemplary embodiments may be changed in various forms, and therefore, the technical scope is not limited to the following exemplary embodiments. Rather, these exemplary embodiments are provided to make the present disclosure thorough and complete.
Unless explicitly described otherwise, the term ‘including’ will be understood to imply the inclusion of a component, but not the exclusion of any other components. Further, various elements and areas in the drawings are schematically drawn. Therefore, the technical ideas are not limited by a relative size or interval drawn in the accompanying drawings.
FIG. 1 is a diagram schematically illustrating an operation of a broadcast receiving device according to an exemplary embodiment.
Referring to FIG. 1 , when an advertisement image starts while a user watches broadcasting, a broadcast receiving device 100 displaying a list of other channels associated with a channel that he or she is watching is disclosed. When the advertisement image starts while the user watches a broadcast, the broadcast receiving device 100 may sense the start of the advertisement image and display the list of other channels associated with the channel that the user is watching and when the user selects one channel from the list, the broadcast receiving device 100 may display the image of the selected channel.
For example, when an advertisement image 20 (e.g., a cosmetics advertisement) starts at intermission time while the user watches baseball broadcasting 10 (e.g., A team vs B team) broadcast on a channel [ 025 ], the broadcast receiving device 100 may sense a start of the advertisement image 20 and display the advertisement image 20 and a list 11 of other channels associated with the baseball broadcasting channel [ 025 ] that the user is watching together. A method for sensing a start of an advertisement image will be described below with reference to FIGS. 4 and 5 .
In this case, the list 11 of other channels may be a sport channel list. In detail, the list 11 of other channels may include a channel [ 026 ] on which a baseball game of another team is broadcast (for example, C team vs D team), channels [ 054 ] and [ 055 ] on which a soccer game is broadcast, and a channel [ 101 ] on which a golf game is broadcast, etc.
In this case, when the user selects a channel [ 054 ] on which the soccer game is broadcast from the list 11 of other channels displayed along with the advertisement image 20 , the broadcast receiving device 100 may change the advertisement image 20 to an image 30 of the channel [ 054 ] on which the soccer game is broadcast, and display the image 30 .
FIG. 1 illustrates that a single broadcast receiving device displays an image, but a plurality of broadcast receiving devices may also display the image. Below, for convenience of explanation, it will be described that the single broadcast receiving device displays the image.
FIG. 2 is a block diagram illustrating a configuration of the broadcast receiving device according to an exemplary embodiment.
Referring to FIG. 2 , the broadcast receiving device 100 includes a broadcast receiver 110 , an input 120 , a storage 130 (e.g., memory), a display 140 , a communicator 150 , and a processor 160 .
The broadcast receiving device 100 may be a digital TV but exemplary embodiments are not limited thereto. The broadcast receiving device 100 may be implemented as various electronic devices such as a portable phone, a tablet PC, a notebook PC, a PDA, and a DVD player including the display 140 , or a set top box connected to a separate display device without the display. Below, for convenience of explanation, the broadcast receiving device 100 will be described as a digital TV.
The broadcast receiver 110 may receive a digital broadcasting signal from a broadcasting station or a satellite in a wired manner or a wireless manner. The broadcast receiver 110 may receive various kinds of broadcasting signals transmitted from the broadcasting station through a radio frequency network (RF network) and may receive broadcasting through an IP network from various kinds of servers. In this case, the RF network is a communication network which radiates a radio frequency to exchange information. Thus, a wideband is expanded and a link of additional services is possible. An Internet protocol network (IP network) is a network of protocol to exchange a packet between several independent networks, as a rule, to connect communication networks independently operated on the Internet.
A detailed configuration of the broadcast receiver 110 and a receiving method by the broadcast receiver 110 may be variously implemented according to an exemplary embodiment.
The broadcast receiver 110 may receive EPG information including information about a plurality of broadcasting programs. Program information, e.g., information associated with the broadcasting program, is called EPG information. For example, an electronic program guide (EPG) may include information associated with a program such as a program title, a program type, a program date, program classification, playing time of a program, characters of a program, a director of a program, a writer of a program, awards that a program has won, actors of a program, etc. Further, the program information may include information corresponding to a program such as a program title, a program broadcasting period, a program broadcasting day, program broadcasting time, a program type, program classification, a director and characters of a program, and a program plot.
The input 120 inputs a user command to the broadcast receiving device 100 . The input 120 may input user commands controlling the broadcast receiving device 100 . When the display 140 (described below) includes a touch pad, the input 120 may be included in the touch pad of the display 140 and may be implemented as a remote controller, a portable phone, and a mouse, etc. When the input 120 is implemented as a remote controller, a portable phone, or a wireless mouse, the broadcast receiving device 100 may remotely receive the user command. When the input 120 is implemented as a wired mouse, the broadcast receiving device 100 may be physically connected to the mouse to receive the user command.
The input 120 may receive the user command for selecting the wanted channel from the list of other channels displayed. For example, when sensing that the advertisement image starts while the user watches a program image, the broadcast receiving device 100 may display a list of other channels associated with the channel that the user is watching on the display 140 . In this case, if the list of other channels associated with the channel that the user is watching is displayed, the input 120 may receive the user command for selecting one channel from the list of other channels displayed.
When sensing that the advertisement image starts while the user watches the program image, the input 120 may receive a user's preference channel information for generating the list of other channels displayed.
In this case, the list of other channels associated with the channel that the user is watching may be generated using a plurality of channel information pre-classified according to the program type that is broadcast on the channel or a plurality of preference channel information previously input through the input 120 (described below) by the user.
In this case, the list of other channels may be generated using the plurality of channel information on which a program having a type similar to that of the channel that the user is watching among the plurality of channel information pre-classified is broadcast. In this case, the plurality of channels on which the program having the type similar to that of the channel that the user is watching may be a plurality of channels having the same frequency as the channel that the user is watching. The broadcasting provider transmits the plurality of channels within the same frequency together for transmission efficiency. The channels having the same frequency are highly likely to be the channels associated with each other to be appropriate to generate the list of other channels.
For convenience of explanation, the types of programs broadcast described above are sports broadcasts. However, the types of programs may be various content types such as drama, music, movie, and home shopping.
For convenience of description, it is described above that the list of other channels associated with the channel that the user is watching is in a table form, however, the list of other channels may be implemented in many different forms. For example, the list may be implemented as a thumbnail form and a form in which the images of the plurality of channels associated are displayed in a picture in picture (PIP) scheme.
The storage 130 (e.g., memory) stores various programs and data for driving the broadcast receiving device. For example, the storage 130 may store an operating system (OS) for driving the broadcast receiving device 100 , an application for performing various functions, data used while the application is executed, etc. In addition, the storage 130 may store various software modules such as a base module, a sensing module, a communication module, a presentation module, a web browser module, and a service module.
The storage 130 may store the plurality of channel information. In detail, the storage 130 may store the plurality of channel information for generating the list of other channels associated with the channel that the user is watching. In this case, the storage 130 may store the plurality of channel information classified according to the types of broadcasting programs. The plurality of channel information classified according to the types of broadcasting programs may be one previously input in a manufacturing step of the broadcast receiving device 100 , one classified by the EPG information received through the broadcast receiver 110 , or one received by the communicator 150 (described below) connected to an external server. Further, the storage 130 may store the plurality of preference channel information input through the input 120 by the user.
The display 140 may display images obtained by decoding the digital broadcasting signal received by the broadcast receiver 110 . In detail, the display 140 may display the broadcasting program image and the advertisement image. Further, if the start of the advertisement image after the program image is sensed, the display 140 may display the list of other channels associated with the channel that the user is watching. In this case, the display 140 may display the list of other channels along with the advertisement image and may also display only the list of other channels. In this case, the display 140 may display the list of other channels on a main screen and may also display the list of other channels on a sub-screen, which is some area of the main screen in a PIP scheme.
The PIP may be a small image additionally overlaying the present image. By using this, the user may watch various additional information of the present image, the list of other channels, an image of a channel selected from the list of other channels and a size and a position of the sub-screen may be adjusted.
If the user selects one channel from the list of other channels displayed, the display 140 may display the image of the selected channel. In this case, the display 140 may change the image of the main screen to the image of the selected channel and display the image of the selected channel or may display the image of the selected channel on the sub-screen which is some area of the main screen in the PIP scheme.
For convenience of explanation, it is described above that the broadcast receiving device 100 includes the display 140 , but the broadcast receiving device 100 may also be implemented in a state in which it is connected to a separate display device without the broadcast receiving device 100 itself, such as a set top box including the display.
The communicator 150 connects the broadcast receiving device 100 to the external device, and may be implemented in a form in which it is connected to the external device through a universal serial bus (USB) as well as a form in which it is connected to the external device through a local area network (LAN) and the Internet network. In detail, the communicator 150 may receive the plurality of channel information for generating the list of other channels from the external device such as a server. In this case, the channel information received may be the channel information classified for each broadcasting program type.
The processor 160 controls a general operation of the broadcast receiving device 100 . In detail, the processor 160 may control the display 140 to display the images obtained by decoding the digital broadcasting signal received by the broadcast receiver 110 . In this case, the image may include the broadcasting program image and the advertisement image.
If the start of the advertisement image after the program image is sensed, the processor 160 may perform a control to display the list of other channels associated with the channel that the user is watching. In this case, the processor 140 may perform a control to display the list of other channels along with the advertisement image or display only the list of other channels. The processor 160 may perform a control to display the list of other channels on the main screen or display the list of other channels on a sub-screen that is some area of the main screen in the PIP scheme. In this case, the processor 160 may perform a control to display the sub-screen while changing the size and position of the sub-screen according to the user command.
The processor 160 may sense the start of the advertisement image using program and system information protocol (PSIP) information included in the digital broadcasting signal received through the broadcast receiver 110 . The PSIP is a standard made for describing programs and data transmitted from a digital TV and various information for TV reception. Here, an example of the standard may include ATSC standard 65 . The PSIP is a set of tables devised to be operated within all transmission streams for the digital TV and provides information for reception by describing information of a virtual channel transmitted from a specific transmission stream. A method for sensing the start of the advertisement image using the PSIP information will be described in detail with reference to FIGS. 3 to 5 .
If the user selects one channel from the list of other channels displayed, the processor 160 may display the image of the selected channel. In this case, the display 140 may change the image of the main screen to the image of the selected channel and display the image of the selected channel or may display the image of the selected channel on the sub-screen which is some area of the main screen in the PIP scheme.
If the start of the advertisement image after the program image is sensed, the processor 160 may perform a control to change the advertisement image to an image of any channel among other channels associated with the channel that the user is watching and display the image of any channel and display the list of other channels in the changed image. If the user selects one channel from the list of other channels displayed, the processor 160 may perform a control to display the image of the selected channel. In this case, the processor 160 may perform a control to change the image of the main screen to the image of the selected channel and display the image of the selected channel or may display the image of the selected channel on the sub-screen which is some area of the main screen in the PIP scheme.
Any channel among the other channels may be a channel having the lowest channel number among other channels associated with the channel watched by the user or may be a channel having the channel number closest to a channel number watched by the user.
The processor 160 may perform a control to display the list of other channels by sensing the start of the advertisement image after the program image and then display the advertisement image from which the list of other channels displayed is removed if the user command is not input for a predetermined time.
FIG. 3 is a diagram schematically illustrating an example of advertisement image start information inserted while a user watches a broadcasting program.
Referring to FIG. 3 , the broadcast receiving device according to an exemplary embodiment may display the advertisement image after program image 1 . For example, if all three advertisement images are displayed, the broadcast receiving device may display program image 2 later. The program image 1 and the program image 2 may be the same broadcasting program and may also be another broadcasting program. The provided broadcasting image may be an advertisement image which is provided by a key station (e.g., national station) or a local station. In the digital broadcasting system, the number of advertisements inserted while a user watches the broadcasting program, insertion timing of advertisement, etc., are defined as an agreement and one illustrated in FIG. 3 is only an example of the agreement. Therefore, upon the actual implementation, the number of advertisements, the insertion timing of advertisement, whether the advertisement image is provided by the key station or the local station, etc., may be changed according to the agreement.
The broadcast receiving device according to an exemplary embodiment may sense the start of the advertisement image using the PSIP information included in the digital broadcasting signal received through the broadcast receiver.

In this case, the digital broadcasting signal is received from a broadcasting station or a satellite in a wired manner or a wireless manner and the digital broadcasting signal includes the signals for the program image and the advertisement image. Next, the broadcast receiving device displays the images obtained by decoding the received digital broadcasting signal. The broadcast receiving device displays the program image (S 720 ). Next, it is sensed whether the advertisement image starts while the user watches the program image displayed (S 730 ). When the start of the advertisement image is not sensed (S 730 -N), the broadcast receiving device continuously displays the program image that the user is watching. When the start of the advertisement image is sensed (S 730 -Y), the broadcast receiving device displays the list of other channels associated with the channel that the user is currently watching (S 740 ). In this case, the broadcast receiving device may display the list of other channels on the main screen or display the list of other channels on the sub-screen which is some area of the main screen in the PIP scheme. When the start of the advertisement image is sensed, the broadcast receiving device determines whether the preference channel is stored to display the list of the preference channels if the stored preference channels are present and display the list of other channels associated with the channel that the user is watching if the stored preference channels are not present. In this case, the list of other channels associated with the channel that the user is watching may include a plurality of channels having a type similar to that of the channel that the user is currently watching.
Next, the broadcast receiving device determines whether the user selects one channel from the list of other channels displayed (S 750 ). If the user selects one channel from the list of other channels (S 750 -Y), the broadcast receiving device may display the image of the selected channel (S 770 ). In detail, if the user selects one channel from the list of other channels using the input such as a remote controller, a touch screen, and a mouse, the broadcast receiving device may display the image of the selected channel. The broadcast receiving device may display the image of the selected channel on the main screen or display the image of the selected channel on the sub-screen which is some area of the main screen in the PIP scheme. If the user does not select one channel from the list of other channels while a predetermined time elapses (S 750 -N), the broadcast receiving device may continuously display the advertisement image from which the list of other channels is removed (S 760 ).

FIG. 9 illustrates another example of the operation of the broadcast receiving device, and when the advertisement image 20 (for example, cosmetics advertisement) starts at the intermission time while the user watches the baseball broadcasting 10 (for example, A team vs B team) broadcast on the channel [ 025 ], if the start of the advertisement image 20 is sensed, the broadcast receiving device 100 may change the advertisement image 20 to the image 30 of any channel (for example, [ 026 ]) among other channels associated with the channel [ 025 ] on that the user is watching and display the image 30 of any channel.
In detail, the broadcast receiving device 100 may automatically change the advertisement image to the image of the channel [ 026 ] (e.g., C team vs D team) broadcasting another baseball game having the lowest channel number or the closest channel number among the channels associated with the channel [ 025 ] on which the advertisement image is watched and display the image of the channel [ 026 ]. In this case, the broadcast receiving device 100 may display the advertisement image 21 in the changed image in the PIP scheme. In this case, the broadcast receiving device 100 may display the list of other channels associated with the channel that the user is watching.
According to an exemplary embodiment, the broadcast receiving device 100 may display the list 11 of other channels associated with the baseball broadcasting channels
and [ 026 ] in a PIP scheme, and display the advertisement image 21 on the sub-screen which is some area of the main screen on which the changed image 30 is displayed. In this case, the list 11 of other channels may be the sport channel list. In detail, the list 11 of other channels may include the channels [ 054 ] and [ 055 ] on which the soccer game is broadcast and the channel [ 101 ] on which the golf game is broadcast, etc.
In this case, when the user selects a channel [ 054 ] on which the soccer game is broadcast from the list 11 of other channels displayed, the broadcast receiving device 100 may change the changed image 30 to an image 40 of the channel [ 054 ] on which the soccer game is broadcast and display the image 40 . In this case, the broadcast receiving device 100 may display the advertisement image 21 in the image 40 of the channel [ 054 ] on which the soccer game is broadcast in the PIP scheme.
When the user wants, i.e., when the user selects the sub-screen using the input, the image of the main screen and the image of the sub-screen may be switched.
As described above, according to one or more exemplary embodiments, if the advertisement broadcasting starts while the user watches the digital broadcasting, the user may minimize time consumed to change many channels one by one, or to confirm broadcasting contents on other channels by displaying the received EPG information. Further, it is possible to provide user customized advertisement by confirming preference advertisement depending on the user's channel selection.
