Description

Broadcast Receiving Apparatus for Displaying Advertising Video During Channel Switching Time and Control Method thereof {Broadcast Receiving Apparatus for displaying an advertisement during Channel Zapping Time and method

The present invention relates to an advertisement method using a channel switching time and an apparatus for performing the method, and more particularly, multimedia data previously stored in a blank period, that is, a channel switching time, due to a delay occurring during a channel switching in a broadcast receiving apparatus. The present invention relates to a method and an apparatus therefor.

Today, not only in our homes, but everywhere we live, TV has long been an indispensable necessity for life. Following cable TV and satellite broadcasting, new media called IPTV is spreading to us, and TV is coming to us more and more. In addition, as TV becomes an age of convergence of broadcasting and communication, the functions of TV are diversified, and the performance of products is being advanced.

In addition, with the rapid increase in network speed and the development of QoS technology on the Internet, IPTV (Internet Protocol Television), which enables digital broadcasting services such as satellite, cable, and terrestrial, is available on the Internet. Each company develops and launches IPTV products using its own technology, and various standardization activities and researches related to IPTV are actively conducted.

IPTV refers to a service that provides information service, video content, and broadcasting to a television receiver using high-speed Internet. It's a type of digital convergence in terms of the convergence of the Internet and television. The difference with traditional Internet TV is that it uses a television receiver instead of a computer monitor and a remote controller instead of a mouse.

IPTV provides television services using Internet protocols over a network that includes transmission over a broadband connection. IPTV additionally provides Internet services such as Web surfing and Voice over Internet Protocol (VoIP) as well as Video on Demand (VOD) using the same infrastructure.

IPTV requires only a television set, a set-top box and an internet connection. You can add a set-top box or dedicated modem to your television and turn it on just as you would turn it on. Therefore, even a person who is not familiar with a computer can use the remote control to receive various contents and additional services provided by the Internet such as watching movies, home shopping, home banking, online games, and MP3s as well as searching the Internet.

IPTV is not different from general cable broadcasting or satellite broadcasting in that it provides broadcasting contents such as video, but interactive services and personalization services are possible due to the added interactivity. For example, an interactive program guide may be provided in which viewers search for content by title or actor name. In addition, IPTV can provide a combination of three services such as video, voice, and the Internet through a single line. That is, television, telephone, and the Internet are serviced through one line.

Existing digital broadcasting service has transmitted all the contents to each viewer. Therefore, the cable or satellite operator can provide the content as much as the limit of the line connected to the viewer's home, and the viewer can select the content within the limit. In contrast, IPTV transmits only the content selected by the viewer to the viewer. Thus, there is a margin of bandwidth, and the viewer's choice is not limited by the limitations of the line.

However, IPTV, which provides only one content to the viewer, has a problem in switching channels. In the process of channel switching, there is a problem that a network delay occurs that requires access to a specific multicast address from a IPTV terminal through a network in order to receive a broadcast related to a channel to be switched. In addition, there is a problem that a delay required for buffering a certain amount of data necessary for showing video data corresponding to a channel normally switched on a TV screen occurs. This delay causes a blank period in which the user sees nothing during channel switching.

The delay time is expressed as a channel zapping time or a channel switching time. Such channel switching time has been a major problem for operators, and accordingly, various technologies for reducing such channel switching time are being studied. Accordingly, the technology to reduce the channel switching time to about 2 seconds until now has been developed. However, there is a limit in shortening the channel switching time.

The present invention has been devised to improve the above problems, and the technical problem to be achieved by the present invention is to provide advertising image data, such as advertising, instead of the conventional black screen processing during the blank period due to the delay when switching channels of the TV It is aimed at making viewers feel less bored and providing new advertising markets in terms of operators.

According to the present invention for achieving the above object, a broadcast receiving device includes a broadcast receiving module for receiving a broadcast signal; And a memory module for storing image data and a control module for outputting image data previously stored in the memory module during a channel conversion time.

The memory module may further include metadata corresponding to the image data, and when the channel change is made, the control module analyzes the channel change signal for the channel change and then retrieves the metadata corresponding to the channel change signal. Preferably, the video data corresponding to the metadata is output.

The video data is preferably advertising video data.

In addition, the metadata may include at least one of channel, region, and advertisement date information.

When the advertisement image data is output, the control module stores the advertisement exposure information including the output number and exposure channel information of the advertisement image data in a memory module, and transmits the advertisement exposure information to the outside. It is preferable to further include.

In addition, the advertisement image data is preferably in the form of an image file.

The broadcast receiving module may receive a signal multiplexed with a broadcast signal and image data, and further includes a demultiplexer for separating the signal received from the broadcast receiving module into a broadcast signal and image data.

In addition, the broadcast receiving module is preferably a tuner module for receiving the RF signal multiplexed with the image data from the transmission system.

The apparatus may further include an AV decoder for separating and outputting the broadcast signal into audio and video.

In addition, the broadcast receiver is preferably any one of a TV, a set top box (STB), a digital multimedia broadcasting (DMB) receiver, a mobile phone broadcast receiver, and a personal multimedia player (PMP).

On the other hand, a broadcasting system according to an embodiment of the present invention includes a broadcasting center for serving a broadcast signal; And a broadcast receiving device that stores the video data and outputs the pre-stored video data during a channel conversion time when the channel is changed during the reception and output of the broadcast signal.

The image data is advertisement image data, and the operator system may further include a function of receiving advertisement exposure information on information on which the advertisement image data is output from the broadcast receiving device.

In addition, the operator system preferably further comprises a customer management module for managing information of the customers owning the broadcast receiving device.

The operator system may further include a billing module that calculates an advertisement fee by linking the received advertisement exposure information with information of customers of the customer management module.

Meanwhile, a control method of a broadcast receiving apparatus according to an embodiment of the present invention includes a broadcast receiving apparatus for receiving and outputting a broadcast, the broadcast receiving apparatus storing image data in a built-in memory; When the broadcast receiving apparatus detects a channel change during broadcast output, outputting the video data pre-stored in the memory module during the channel conversion time, and when the channel conversion is completed, the broadcast receiving apparatus converts the screen to the changed channel. Steps.

The video data is preferably advertising video data.

In addition, after the screen is converted, the broadcast receiving device receives a confirmation button from the user; And converting the screen into the advertisement image data.

When the search button is input from the user in the step of outputting the advertisement image data, it is preferable that the screen is converted to the homepage after being associated with the advertisement image data.

In addition, after the screen is converted, the broadcast receiving device receives a confirmation button from the user; And converting the screen into the advertisement image data.

From the viewer's point of view, the multimedia data is displayed instead of the conventional black screen processing in this channel switching time, thereby reducing the boredom felt at the channel switching time.

On the corporate side, it is also possible to utilize the channels and channels between channels created by moving from the existing analog broadcasting to the digital broadcasting system as a new form of advertising exposure that has not existed in the advertising market. It will be possible to provide a technique for efficient online access. In this case, the advertisement is exposed for about 2 seconds, but the viewer focuses on the TV screen when switching channels, and thus the effect of the advertisement exposure is very high.

In addition, considering the reality that the channel switching operation of the remote control of the viewers due to the increase in the number of channels, viewers are repeatedly watching the same video by high concentration even for a short time, and thus have a very high advertising effect.

1 is a diagram showing the configuration of a satellite broadcasting system according to an embodiment of the present invention.

As shown in FIG. 1, the advertisement image data sent from the advertisement delivery device 22 in the advertisement provider system 20 and the broadcast data transmitted from the broadcasting center 10 are multiplexed by the multiplexing system 30 and then a high output amplifier ( A high power amplifier (HPA) 40 transmits to the satellite repeater. After receiving the signal, the broadcast receiving device 50 stores the dual advertisement image data in the internal memory. Meanwhile, when transmitting the advertisement image data, the metadata is recorded in the content, and the broadcast receiving device 50 reads the metadata of the corresponding image data file stored in the internal memory and exposes the metadata on the screen.

When TV users perform the channel switching operation, the corresponding contents recorded in the metadata are found and displayed on the screen during the switching time, and as soon as the channel switching is completed, the decoded screen of the switching channel is exposed.

When the channel is switched, the above operation is repeated, and the information of the exposed advertisement operation state is stored in the internal memory.

The stored advertisement exposure information transmits all the information accumulated in real time or for a predetermined time to the customer management device 24.

The advertisement exposure information stored in the internal memory of the broadcast receiver is read through the return path network of the communication line such as the Internet of the telecommunication company connected to the broadcast receiver.

The advertisement exposure information is managed by a DB such as the number of exposures and the exposure channel for each customer or the whole. The advertisement exposure information is stored in the DB such as the type and number of impressions of the users, viewers by channel switching, and the search and purchase of advertisement-related homepages or shopp malls by the search operation. You will be provided with the necessary materials (evidence of advertisement exposure).

Meanwhile, the billing device 26 included in the advertisement system 20 performs a function of calculating an advertisement cost by using advertisement exposure information loaded in the DB. Through this, the revenue structure of the advertiser system can be realized by charging the advertiser.

Meanwhile, in the present invention, an example of transmitting the advertisement image data to the broadcast receiver is an example of multiplexing and transmitting the broadcast signal and the advertisement image data under a satellite broadcasting system. However, this is only an example. Of course, it can be applied to a system for multiplexing the broadcast signal and sending it.

In addition, the method of transmitting the advertisement image data through a channel separate from the broadcast signal can also be applied. That is, the advertisement image data is not transmitted to the broadcast receiving apparatus after multiplexing with the broadcast signal, and the broadcast signal is transmitted through the satellite in the conventional channel, that is, the satellite broadcast, and the advertisement image data is transmitted through a network such as the Internet. It may be fine.

In addition, the advertisement image data is not limited to being transmitted or pushed through a network such as the Internet as described above. In addition, a download method may be used in a broadcast receiver.

Specifically, the broadcast receiver accesses the advertising service provider system, authenticates the customer management device, accesses the database where the advertisement video data is stored, and reads the image data of the new update target in the internal memory of the broadcast receiver. . The download of the advertisement image data is automatically executed in the control module without a separate operation by the user every predetermined time (for example, once a day) in the broadcast receiver. Alternatively, the user may access the advertisement provider system using a remote controller and select and download advertisement image data that he / she wants to see.

2 is a block diagram of a broadcast receiving apparatus according to an embodiment of the present invention.

Broadcast receiving apparatus 200 according to an embodiment of the present invention is largely tuner module 210, demultiplexer 220, memory module 230, remote control receiving module 240, network module 250, AV decoder 260 And a control module 270.

The tuner module 210 receives the RF signal from the transmission system. The RF signal is a signal in which advertisement image data is multiplexed together with a broadcast signal.

The de-multiplexer 220 separates the RF signal received through the tuner module 220 into a broadcast signal and advertisement image data.

The memory module 230 stores the separated advertisement image data. The memory module 230 may be a flash memory, a DRAM, a hard disk drive (HDD), or the like.

The remote control receiving module 240 receives a user's command from the remote control.

The network module 250 connects to the external Internet and performs a role of transmitting and receiving data.

The AV decoder 260 performs a function of separating and outputting the separated broadcast signal into audio and video.

When the channel change is made, the control module 270 outputs the advertisement image data previously stored in the memory module 230 during the channel conversion time, which will be described in more detail below.

Meanwhile, the control module 270 continuously updates the advertisement image data according to a schedule, and the memory module 230 deletes the data that is no longer needed.

The above example is an example of the broadcast receiving apparatus 200 when the advertisement image data is multiplexed with a broadcast signal and then transmitted together through a satellite or a cable.

In addition, the broadcast signal is received via a satellite or cable, and the advertisement image data is received from the network module 250 through the Internet, and then immediately stored in the memory module 230 without passing through the demultiplexer 220 directly. Of course it can.

3 is a block diagram of a broadcast receiving apparatus according to another embodiment of the present invention.

The broadcast receiving device 300 shown in FIG. 3 is an IPTV receiver (Internet TV, Internet Protocol TV) that serves broadcast through the Internet.

The demultiplexer 320, the memory module 330, the remote controller receiving module 340, and the AV decoder 360 are similar to those of FIG. 2, and thus a detailed description thereof will be omitted.

The network module 350 receives broadcast data and advertisement image data through an internet communication network. After the received data passes through the demultiplexer 320, the advertisement image data is transmitted to the memory module 330, and the broadcast data is transmitted to the AV decoder 360.

As described above, a method of outputting the advertisement image data during the channel switching time after storing the advertisement image data in the memory module 230 will be described in detail later with reference to FIG. 4.

4 is a flowchart illustrating a method of outputting advertisement image data during a channel switching time according to an embodiment of the present invention.

When the viewer operates the remote control and clicks the channel switching button (S410), the remote control receiving module included in the broadcast receiver sends the channel switching signal to the control module, and accordingly, the controller switches the channel (S420).

At this time, the control module receives the channel switching signal, and loads the image data corresponding thereto from the memory module (S430). At this time, in order to facilitate selection of the image data, each image data includes metadata. One embodiment of the metadata is shown in FIG.

The metadata may include various information as shown in FIG. 7.

To explain the advertising channel most easily, when the user switches the channel to 6, the control module outputs data corresponding to the TV advertisement of the electronics, and when the user switches the channel to the 7, the control module L The data corresponding to the former refrigerator advertisement will be output.

Meanwhile, metadata may include local information in addition to an advertising channel. Therefore, it is possible to distinguish the exposure area for each advertisement.

In other words, if you want to expose the refrigerator advertisement of the L electronic only in the Busan area, if you set the "Busan" in the metadata field of the metadata and transmit it to the broadcast receiver, only the broadcast receiver installed in the "Busan" area Video data is stored in internal memory. Alternatively, all data may be stored without considering local items, and may be output only when the control module compares the local items at the time of output.

Through this, it can be used in advertisements that are needed only in a specific region, for example, restaurants or other local advertisements for surrounding businesses.

In addition, by adding an advertisement date item to the metadata, it is possible to restrict the display of the advertisement only when and when.

In addition, although not shown in the drawings, time information or other program information may also be added. This can of course show the advertisement associated with a particular program. For example, when a user switches a channel to a fishing broadcast, the advertisement image data is associated with a program, such as showing a fishing rod advertisement image data, so that the user's desire to purchase can be made stronger.

After the advertisement image data is exposed as described above, when the decoding of the signal for the conversion channel is completed (S440-Y), the advertisement image data is switched back to the image of the conversion channel (450).

After that, when the user wants to watch the advertisement video just viewed, the user may click the reconfirmation button. When the user clicks the reconfirmation button (S460-Y), the advertisement image is output again (S470).

5 is a flowchart illustrating a method of outputting advertisement image data during a channel switching time according to another embodiment of the present invention.

Steps S510 to S530 are similar to steps S410 to S430 of FIG. 4, and thus detailed description thereof will be omitted.

If the user operates the advertisement stop button while the advertisement image is output (S540), the advertisement continues to be displayed. Therefore, you can continue to see the advertisement without regard to the channel switching time.

After this, if the advertisement stop button is operated again (S550), the advertisement stop is finished and it is determined whether the channel switching is completed, and if it is completed (S560-Y), the converted channel is output (S570).

6 is a flowchart illustrating a method of outputting advertisement image data during a channel switching time according to another embodiment of the present invention.

Steps S610 to S640 are similar to steps S510 to S540 of FIG. 5, and thus a detailed description thereof will be omitted.

When the user is interested in an advertisement exposed for a short time of the channel switching time and stops by a stop function or the like, the user operates a search button to check detailed product information (S650).

Thereafter, the homepage associated with the advertisement is connected to provide a search function and a search function for related products or various products (S660).

Afterwards, if the search button is operated again (S670), the advertisement stops and the channel switching is completed. If it is completed (S680-Y), the converted channel is output (S690).

As home shopping functions are provided between the channels, the viewers can have a higher exposure to broadcast viewers, thereby increasing their purchasing power and making them more accessible to viewers.

In paying broadcasting, home shopping channels are placed among terrestrial broadcasting channels, which have high channel preference, because they are easily accessible to viewers, and the product sales business of home shopping channels is developing due to this policy.

 As described above, if the advertisement image is exposed for a long time by stopping the advertisement and reconfirming the button, there is a high possibility that the user will operate the search button afterwards. Make the search homepage visible.

8A and 8B show a state of a screen when a channel is changed using a conventional broadcast receiver and a broadcast receiver according to the present invention, respectively.

As shown in FIG. 8A, in the conventional broadcast receiving apparatus, when a user changes a channel from 6 to 8, the user should see a black screen without any content during the channel switching time, as shown in FIG. 8B. According to the broadcast receiving device according to the advertisement image data can be viewed during the channel switching time.

Up to now, the preferred embodiment of the method for outputting the pre-stored advertising image data in the channel switching time has been described in detail.

Meanwhile, in the present embodiment, the advertisement image data has been described. The above-described advertisement image data may be various kinds of video, audio, and pictures.

In addition, the "IPTV" mentioned in this embodiment corresponds to an example of the "broadcast receiver". The present invention is not limited to IPTV, but may be applied to broadcast receivers other than IPTV. Examples of broadcast receivers include STB (Set Top Box), DMB (Digital Multimedia Broadcasting) receiver, and various portable devices having a broadcast reception function (for example, mobile phones, navigation devices, and personal multimedia players). Can be mentioned.

In addition, although the preferred embodiment of the present invention has been shown and described above, the present invention is not limited to the specific embodiments described above, but the technical field to which the invention belongs without departing from the spirit of the invention claimed in the claims.
