Description

Apparatus and method for automatically linking adjacent channel broadcasting services in a mobile digital broadcasting environment, and a computer-readable recording medium recording the broadcasting service automatic linking program for the same {APPARATUS AND METHOD FOR AUTOMATICALLY LINKING BROADCASTING SERVICE OF NEIGHBOR-CHANNELS IN MOBILE DIGITAL MULTIMEDIA BROADCASTING, AND COMPUTER-READABLE RECORD MEDIUM WITH BROADCASTING SERVICE AUTO-LINKING PROGRAM FOR THE SAME}

The present invention provides TPEG priority reception, service preference, existing reception history, and similar similar service in automatically linking a broadcast service to an adjacent channel when a receiving terminal leaves a coverage area of a service channel currently being serviced in a mobile digital broadcasting service environment. The present invention relates to a technology for maximizing convenience of a broadcasting service user in consideration of a catalog database.

In general, the broadcasting service started from broadcasting for transmitting and receiving analog television or analog radio signals and has now reached the stage of providing digital broadcasting service. These digital broadcasting services include terrestrial digital multimedia broadcasting (T-DMB), which is used for mobile phones or vehicles, as well as television, China Mobile Multimedia Broadcasting, a mobile mobile broadcasting service developed by China, and terrestrial broadcasting in Japan. ISDB-T, the DMB standard, and Digital Video Broadcasting-Terrestrial (DVB-T), the European digital broadcasting standard, are being developed in various ways around the world.

Such digital broadcasting services are premised on mobility, such as terrestrial digital multimedia broadcasting (T-DMB). In such a mobile digital broadcasting service, a user can always receive a broadcast anytime and anywhere with a receiving terminal for viewing or listening to a mobile phone or terrestrial digital broadcasting.

However, in terrestrial digital multimedia broadcasting, channel setting or broadcasting service setting is individually defined for each region (region), and thus, when the receiving terminal leaves the service region for each channel while moving, the corresponding service cannot be continuously received. That is, in the case of leaving the service area of the current broadcast service, the receiving terminal generally does not detect the departure of the service area and continuously tries to reproduce only the channel of the selected frequency.

On the other hand, conventionally, when a terminal receiving a digital broadcast leaves the service area of the broadcast service, the receiving terminal detects this and searches for adjacent channels by itself. When searching for an adjacent channel as described above, the terminal is configured to receive the first searched channel among the signals of the searched adjacent channel. That is, it does not consider what channel the user currently selects and receives. Therefore, when the user moves out of the service area to another service area through various means such as a car or a bus, the user first receives a broadcast service set by the terminal.

Therefore, the user is not provided with the same service as the broadcast service he is watching or listening to, and the inconvenience of having to search the entire channel every time he leaves the service area and select the desired channel among the searched channels. If the user is driving a car, the problem may be a risk that may cause an accident.

An object of the present invention is to provide TPEG priority reception, service preference, existing reception history, and the same in automatically linking a broadcast service to an adjacent channel when a receiving terminal leaves a coverage area of a service channel currently being serviced in a mobile digital broadcasting service environment.

(207); When a service area deviation of mobile digital broadcasting is detected due to regional movement, a broadcasting service item having a lower preset digit having the same service ID compared to the service ID of an existing broadcasting service received in the service area before departure from the first database of the memory unit. Is obtained in a newly entered service area, the control unit 205 for setting the obtained broadcast service item to a similar service and controlling the wireless unit to link a channel to the similar service.

In this case, the memory unit 207 further includes a second database for storing the broadcasting service preferences of the region of the user based on at least one of the playing time and the number of times of the broadcasting service for each receiving terminal. When the deviation of the service area according to the movement of the area is detected, it is preferable to control the radio unit to set the preferred service based on the broadcasting service preference in the newly entered service area from the second database of the memory unit and link the channel to the preferred service.

In addition, the memory unit 207 further includes a third database for storing information of channels provided with the TPEG service for each region, and the controller 205 receives TPEG priorities in user setting when the service area deviation is detected due to the movement of the region. In this case, it is preferable to control the radio unit to acquire the TPEG serviceable channel in the newly entered service area from the third database of the memory unit and link to the obtained TPEG serviceable channel.

In addition, the memory unit 207 may further include a fourth database for storing information of a link designation channel preset by a user for each region, and the controller 205 may detect the departure of the service region according to the movement of the region. It is preferable to control the radio unit to link to the link designation channel if the link designation channel exists in the newly entered region by querying the database.

The method according to the present invention comprises a first method for setting a first database for storing channel and service information for a mobile digital broadcast for each region in order to automatically link a broadcast service in response to local movement of a receiving terminal in a mobile digital broadcasting environment. step; Detecting a departure from the service area according to the movement of the area; A third step of retrieving a service area newly entered from a first database by a lower predetermined digit from a first database in comparison with the service ID of an existing broadcasting service received in the service area before the departure in response to the area departure; A fourth step of setting the obtained broadcast service item as a similar service when acquiring a broadcast service item as a result of the search; And a fifth step of controlling the wireless unit to link the channel with the similar service set above.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described with reference to the accompanying drawings. It should be noted that the drawings of the present invention attached hereto are provided for the purpose of helping understanding of the present invention, and the present invention is not limited to the shape or the arrangement exemplified in the drawings of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS The above and other features and advantages of the present invention will be more apparent from the following description taken in conjunction with the accompanying drawings, in which: FIG.

1 is an exemplary diagram of a terrestrial digital broadcasting system for explaining the technical idea of the present invention.

First, the digital broadcasting providing server 10 is an apparatus for providing a terrestrial digital broadcasting service. The digital broadcasting providing server 10 may be implemented as a single server or a plurality of servers. For example, a server for transmitting a KBS broadcast and a server for transmitting an MBC broadcast may be separately provided, or a single broadcast server may manage all of them. In addition, a server for transmitting individual broadcasts (eg, KBS, MBC) may also be composed of several server devices.

In addition, depending on the region, the digital broadcasting providing server 10 may operate different servers even from the same broadcaster, and may manage the entire region collectively in one digital broadcasting providing server 10. For example, a server providing the KBS broadcasting service covering Seoul and Gyeonggi area and a server providing the KBS broadcasting service covering the Daejeon and Chungcheong area may be different servers, or a single server may cover an entire broadcast. It can also be managed.

In the present invention, all the broadcasts are shown as being provided through one digital broadcast providing server 10 for convenience of description. However, the digital broadcast providing server 10 may be configured to have a larger number of broadcast servers according to the region or the number of broadcasters. As described above, specific matters related to the number of broadcast servers are related to the design of a system for providing terrestrial digital services, and thus, the present invention will not limit these matters.

The first broadcast network 20 and the second broadcast network 30 represent a network for delivering contents of a broadcast service according to a region. For example, if the first broadcast network 20 is one network for covering Seoul and Gyeonggi, South Korea, the second broadcast network 30 is one network for covering Daejeon and Chungcheong, Korea.

Accordingly, a plurality of base stations for providing respective broadcast service contents may exist below the first broadcast network 20. In FIG. 1, the first digital broadcast transmitter 40 is set as one of them. In addition, a plurality of base stations for providing respective broadcast service contents may exist below the second broadcast network 30. In FIG. 1, the second digital broadcast transmitter 50 is set as one of them. Let's do it.

As described above, the first digital broadcast transmitter 40 and the second digital broadcast transmitter 50 are base stations or related equipment for transmitting broadcast service contents covering different regions as described above.

It is assumed that the digital broadcasting reception terminal 100 for receiving digital broadcasting in such a digital broadcasting environment receives digital broadcasting service contents in the region of the first digital broadcasting transmitter 40. In this case, the digital broadcast receiving terminal 100 may be provided with a service searched for in its desired area. For example, assuming that the first digital broadcast transmitter 40 is a digital broadcast transmitter covering Seoul and Gyeonggi, which are the metropolitan areas of the Republic of Korea, the digital broadcast receiving terminal 100 is the type of broadcast service content as shown in FIG. Can be received.

FIG. 2 shows channel information and service information on broadcast service contents that can be received in Seoul and Gyeonggi, Korea. As an example of such information, a frequency band and a service label service of a corresponding service are provided. ID (Service ID), subchannel ID (Shbch ID), service type (Serv Type), bit rate (BitRate) and the like are also shown.

It is assumed that the digital broadcasting reception terminal 100 is included in the region of the first digital broadcasting transmitter 40 to listen to one of the services shown in FIG. 2, for example, YTN broadcasting service contents of the service label. . At this time, when the digital broadcasting reception terminal 100 moves geographically and enters the region of the second digital broadcasting transmitter 50, as shown in FIG. 1, broadcast contents provided in different regions are shown in FIG. Like this, different types and different frequencies are used.

FIG. 3 shows channel information and service information on broadcast service contents that can be received in Daejeon and Chungcheong, South Korea. As shown in FIG. 2, frequencies and service labels and service IDs of the corresponding services are shown. In contrast to [FIG. 2], the information shown in [FIG. 3], for example, in the case of YTN service in Seoul and Gyeonggi area, is serviced with a service label of 'YTN' in the frequency band of 183.008 MHz, but in the Daejeon and Chungcheong areas, 202.736 MHz It is provided in the frequency band with a service label of 'CJB-m YTN'.

Accordingly, the receiving terminal 100 according to the prior art, for example, watches the YTN service and then moves out of the region (Seoul and Gyeonggi) of the first digital broadcasting transmitter 40 to the region (the Daejeon and Chungcheong region) of the second digital broadcasting transmitter 50. In the case of entering, it does not receive a broadcast service at all, or receives a signal of MBC11 FM, which is the nearest channel (199.280 MHz), as shown in FIG. Therefore, the user cannot receive the service continuously.

However, the digital broadcasting reception terminal 100 according to the present invention may search for and provide a channel with high preference when the user presets to move to a channel that the user prefers. As another example, when the digital broadcasting reception terminal 100 according to the present invention is configured to search for a service similar to the broadcast service content that is currently being received, the broadcast service content that is provided among the services illustrated in FIG. It may be set to receive the similar broadcast service content by searching for the broadcast service content most similar to the data of FIG. 3. Unlike this, when a user sets a search for a specific channel in advance, the user may be configured to search for a specific channel first to provide a service.

Such details will be described in more detail below with reference to FIGS. 4 and 5.

4 is a functional internal block diagram of a terminal for receiving a digital broadcast signal according to an embodiment of the present invention.

The radio unit 201 sets the frequency of the broadcast signal received from the antenna under the control of the control unit 205, and after receiving the signal of the set frequency, converts the high frequency signal into a baseband signal.

The signal converted into the baseband signal by the radio unit 201 is input to the decoder unit 203. The decoder unit 203 demodulates and decodes the baseband signal. When the decoder 203 demodulates and decodes the audio signal, the decoder 203 outputs the audio signal through the speaker SPK. The decoder 203 outputs the audio signal to the screen providing unit 211 through the controller 205. In this case, the controller 205 and the decoder 203 may be configured as one chip, and the image signal output from the decoder 203 may be directly output to the screen providing unit 211 without passing through the controller 205. Note that it may be. However, the controller 205 controls an output time point of the output audio signal and the video signal for synchronous control of audio and video.

The control unit 205 controls the radio unit 201 to tune to a frequency band desired by the user, and controls the decoder unit 203 to control demodulation and decoding of the baseband signal. In addition, the user's command is input through the user's key input from the user interface unit 209 or the touch pad input or the user's voice recognition. As such, when a user's command is input, an operation corresponding to the input command is performed. In the present invention, a description of the general process of operating according to the user's command will be omitted.

As described above, the controller 205 controls the decoder 203 to output the same to the speaker SPK and the screen providing unit 211 in synchronization with the demodulated and decoded audio signal and the video signal.

In addition, the control unit 205 detects the departure of the service area according to the present invention, and if the departure of the service area checks the service area of the current area and then searches the channel based on the preference set by the user or similar broadcast service contents. First determines whether to search for a channel or move to a channel preset by the user. When the determination of the channel setting is completed as described above, the radio unit 201 is controlled to tune the corresponding frequency band, and then the decoder unit 203 is controlled to receive the corresponding broadcast service contents to control demodulation and decoding of audio and video. . A more detailed description thereof will be described in more detail later with reference to FIG. 5.

The memory unit 207 stores various control data for providing a terrestrial digital broadcasting service, control data for performing control according to the present invention, data input by a user, and the like. Such a memory may be various types of data storage devices such as a hard disk, a ROM, a RAM, a flash memory, a CD, a DVD, and the like.

The memory unit 207 assists the automatic linking operation performed by the control unit 205 according to the technical idea of the present invention when a local movement (deviation of service area, new service area entry) of the receiving terminal 100 occurs. The first database DB-1 to the fourth database DB-4 are set and operated.

The first database DB-1 is configured to store channel and service information for mobile digital broadcasting by region. For example, the first database DB-1 stores various channel information and service information such as those shown in FIGS. 2 and 3 by region. do.

The second database DB-2 stores the broadcasting service preference of the user for the receiving terminal 100 for each region. In this case, the broadcasting service preference of the user may be implemented based on any one or both of the playing time and the playing count of the broadcasting service made through the receiving terminal 100 so far.

The third database (DB-3) is a configuration for storing the information of the channel provided with the TPEG (Transport Protocol Expert Group) service for each region. Among the digital broadcasting channels, there are channels in which TPEG service is provided and others which are not. If the user is using a DMB / navigation integrated terminal, the TPEG receiving channel will be preferred, and accordingly, the third database (DB-3) stores information of channels for which TPEG services are provided for each region.

The fourth database DB-4 stores the information on the link designation channel preset by the user for each region. If the user has manually set the desired channel for the link, the relevant information is stored.

The user interface unit 209 is a device for allowing a user of the receiving terminal 100 to input a desired command. A key matrix form, a keypad form, a touch pad form, It is made in various forms such as a voice recognition module.

The screen providing unit 211 is a device for visually providing an image of contents provided through a terrestrial digital broadcasting service to a user, and may be configured in various forms such as an LCD, a cathode ray tube, and an LED panel.

5 is a control flowchart of channel setting when a digital broadcast receiving terminal leaves a broadcast service area according to an exemplary embodiment of the present invention.

First, the control unit 205 controls the radio unit 201 and the decoder unit 203 in step S300 to convert the broadcast service content signal received by the radio unit 201 through the antenna to the baseband, and the decoder unit ( In step 203, demodulation and decoding of the audio signal and the video signal including the sound of the baseband broadcast service content is controlled to be output in synchronization with the speaker SPK and the screen providing unit 211.

In this way, while providing the broadcast service content in step S300, the controller 205 proceeds to step S302 to check whether the digital broadcast signal is weak and leaving the service area. If it is determined in step S302 that the broadcast signal is weak and the service area is determined to be out of the service area, the control unit 205 proceeds to step S304, and otherwise, continues to provide the broadcast service of step S300.

In this case, the inspection for departure of the broadcast service region may detect departure of the broadcast service region by examining whether the signal reception strength is weakened below a preset threshold. In addition, in order to prevent the ping-pong phenomenon of the broadcast service area deviation detection, it is more preferable that the wireless unit 201 has two different tuners. For example, if the tuner's signal set as a mail tuner is below the first preset threshold and this condition persists for a certain period of time or becomes weaker, it may be necessary to check whether the tuner set as a secondary is entering another region. Can be. At this time, the check for entering into another area determines that the second threshold value equal to or different from the first threshold value is set to move to another broadcasting service area when the state higher than the second threshold value is maintained for a predetermined time. Can be. As such, techniques for preventing the ping-pong phenomenon are already well known in the handover techniques of the mobile communication terminal, and thus, the technique may be applied using the technique.

On the other hand, if there is only one tuner, if a weak signal is received that is difficult to provide the broadcast service content, other service channels are searched, and if there is a channel having a signal higher than or equal to a threshold among the searched service channels, You may decide to leave the area.

The control unit 205 proceeds to step S304 to check whether the user wants to receive the TPEG service. If the receiving terminal 100 supports the TPEG service and the user desires the TPEG service, the control unit 205 prioritizes the TPEG service available channel for the newly entered region from the third database DB-3. You can search.

However, such a priority may not have a step (S304) according to the format set by the user in advance, and although not shown in FIG. 5, when the receiving terminal 100 does not provide the TPEG service ( The flowchart may be configured not to include the step S304).

In FIG. 5 according to the present invention, a case of a terminal providing a TPEG service will be described. If the terminal supports the TPEG service and the currently provided broadcast service content is the TPEG service, the control unit 205 proceeds to step S306 and searches for the TPEG service channel first, and then proceeds to step S322.

On the other hand, if the UE is not receiving the TPEG service or the UE does not receive the TPEG service, or if the user does not desire the TPEG reception priority, the control unit 205 proceeds to step S308 to determine whether the preference channel is first searched for. Check it. If it is set to search for the preference channel preferentially (S308), the control unit 205 proceeds to step S310, otherwise proceeds to step S312.

First, in step S310, the controller 205 searches the second database DB-2 storing the user preferences of the memory unit 207 and checks whether the corresponding channels exist in the order of the highest channel preference. do. When searching for the channel with the highest preference in the second database (DB-2), set the channel with the highest preference by increasing the frequency count value by 1 and setting the frequency count for each channel setting for the channel set by the user manually. You can also do that. At this time, it is preferable to consider the play time and the play frequency of the individual channels together, but only one of them may be considered for ease of implementation. In addition, preference may be implemented in units of channels or in units of broadcast services.

Next, the case where the similar service is set first will be described. Referring to FIGS. 2 and 3, it can be seen that a service ID is assigned to each service label. The service IDs assigned to each service label are set to the same as the least significant two digits in case of a similar service. For example, the service ID of the YTN service label in the Seoul area is "0xF1E00400", and the lower two digits are '00'. In this case, the similar service has the CJB-m YTN service label in the Daejeon area, and the service ID is "0xF1E00800". . That is, the lower two digits of the service ID of the CJB-m YTN service label of the Daejeon area are also '00', which is the same as the Seoul area.

In another example, the service label of the Seoul area is MY MBC, the service ID is "0xF1E00420", and the lower two digits are '20'. The service ID of the similar service in Daejeon is my MBC11, and the corresponding service ID is "0xF1E00820". That is, it can be seen that the lower two digits of the similar service ID in the Daejeon area are also '20'.

In addition, the service label of the Seoul area is KBS HEART, the service ID is "0xF1E00442", and the lower two digits are '42'. The service ID of the similar service in Daejeon is KBS HEART, and the service ID is "0xF1e00242", and the lower two digits are '42'.

In the case of the similar service, a search is possible by comparing the lower two digits of the service ID corresponding to the service label. To this end, as described above with reference to FIG. 4, the first database DB-1 stores channel and service information for mobile digital broadcasting by region, and the controller 205 detects a service departure and a new entry. If so, the first database DB-1 is searched to obtain a similar service in a new entry area for the existing broadcast service.

On the other hand, when proceeding from step S308 to step S312, the control unit 205 checks whether or not it is set to search for similar services with respect to the broadcast service watched in the previous region. If the similar service is set to be checked first, the control unit 205 proceeds to step S314 and searches for a similar service corresponding to the corresponding service in the manner described above.

However, if the similar service is not set first, the control unit 205 proceeds to step S316 and checks whether the service channel designated by the user exists by referring to the database. If a link designation channel (a channel previously designated by the user as a link to the new entry area) is set in the database DB-4, the process proceeds to step S318 to search for the link designation channel. If there is no service channel specified by the user, the adjacent channel may be sequentially searched to provide the fastest found channel (S320).

As such, when a service channel is searched in steps S306, S310, S314, and S318, the controller 205 proceeds to step S322 and automatically links to the found channel, if necessary. Update various databases.

If the appropriate channel does not exist during the above steps (S310), (S314), and (S318), it may be configured to select the nearest channel as an auxiliary means. Then, the control unit 205 controls the radio unit 201 to link to the adjacent channel, and then controls the decoder unit 203 to receive broadcast service content.

After that, the control unit 205 returns to step S300 to control to provide a broadcast service of the selected channel.

The present invention can also be embodied in the form of computer readable code on a computer readable recording medium. At this time, the computer-readable recording medium includes all kinds of recording devices in which data that can be read by a computer system is stored.

Examples of the computer-readable recording medium include a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, an optical data storage, and the like, and may be implemented in the form of a carrier wave . The computer-readable recording medium can also be stored and executed by a computer-readable code in a distributed manner on a networked computer system. And functional programs, codes, and code segments for implementing the present invention can be easily deduced by programmers skilled in the art to which the present invention belongs.

As described above, the embodiments of the present invention have been disclosed in the present specification and drawings, and although specific terms have been used, they have been used only in a general sense to easily describe the technical contents of the present invention and to facilitate understanding of the invention. And is not intended to limit the scope of the invention.
