<Embodiment>
[First configuration example of Twitter support system]
The Twitter support system according to the embodiment of the present disclosure supports a general user or a broadcaster of content to collect all tweets tweeted on the content while viewing the content. Is. In addition, when using the Twitter service, the Twitter support system assists in quickly viewing a content when it is found that a tweet related to the content has been raised.

FIG. 1 illustrates a first configuration example of a Twitter support system according to an embodiment of the present disclosure.

The first configuration example of the Twitter support system 10 includes a broadcasting device 20, a hash tag RA (Registration Authority) unit 21, a hash tag DB (DataBase) unit 22, and a receiving device 30. The Twitter support system 10 uses a broadcast network 11, a bidirectional communication network 12, and a Twitter server 13.

The broadcasting network 11 includes a terrestrial TV broadcasting network, a satellite TV broadcasting network, a CATV network, an IPTV network, and the like. The bidirectional communication network 12 indicates an IP communication network represented by the Internet. The Twitter server 13 is an existing server that provides a Twitter service, and manages tweets to which hashtags posted by users of the Twitter service are added.

The broadcasting device 20 broadcasts content (program) as MPEG2TS via the broadcasting network 11 in accordance with DVB (Digital Video Broadcasting) (or DVB derived standard) which is a public standard for digital broadcasting. This MPEG2TS includes DVB service information (hereinafter referred to as DVB-SI) corresponding to the content to be broadcast.

The broadcasting device 20 is specific to each service broadcast on the DVB network, which is defined by “Digital Video Broadcasting; Specification for Service Service Information in DVB systems; EN300468 v1.3.1” from DVB-SI of the content to be broadcast. Extract DVB-Triplet used as identification information. In addition, the broadcasting device 20 also extracts the event identifier Eid stored in the DVB-SI event information table EIT, and as shown in FIG. 2, DVB-Triplet + α with the event identifier Eid added to the DVB-Triplet Is generated.

Here, the DVB-Triplet includes the original network identifier ONid stored in the DVB-SI network information table NIT, the transport stream identifier TSid and the service identifier Sid stored in the DVB-SI stream description table SDT. Indicates 3 items of information.

The original network identifier ONid is unique identification information of a set of a plurality of multiplexed MPEG2TS broadcast from the same broadcasting device 20. The transport stream identifier TSid is unique identification information of each MPEG2TS in the set of a plurality of multiplexed MPEG2TSs. The service identifier Sid is unique identification information of each service (so-called channel) in MPEG2TS. The event identifier Eid is identification information of an event (content or a section within the content) in the service.

In addition, when the event identifier Eid is given to the section in the content, there are a plurality of event identifiers Eid for one content. In this case, a plurality of DVB-Triplet + α for one content is also generated.

The broadcasting device 20 uses the WebAPI of the hash tag RA unit 21 to supply one or more DVB-Triplet + α that can uniquely identify each content to be broadcast to the hash tag RA unit 21. Furthermore, the broadcasting device 20 can optionally notify the hash tag RA unit 21 of a content ID that is identification information of the content to be broadcast and a hash tag to be given to a tweet made about the content. The content ID may or may not have uniqueness (global uniqueness).

The hashtag RA unit 21 registers one or more DVB-Triplet + α corresponding to one content supplied from the broadcasting device 20 in the hashtag DB unit 22. Further, when the broadcast apparatus 20 is notified of the content ID and the hash tag together with the DVB-Triplet + α, the hash tag RA unit 21 associates them with the DVB-Triplet + α and registers them in the hash tag DB unit 22. .

Furthermore, the hash tag RA unit 21 associates a hash tag notified from the receiving device 30 or other external device using the Web API of the hash tag RA unit 21 with DVB-Triplet + α, and a hash tag DB unit 22 can be additionally registered.

Thereby, as shown in FIG. 3, a database in which the content ID and one or more hash tags are associated with one or more DVB-Triplet + α is constructed in the hash tag DB unit 22.

Further, the hash tag RA unit 21 refers to the hash tag DB unit 22 in response to a hash tag search request corresponding to DVB-Triplet + α from the receiving device 30 using the search WebAPI, and the DVB-Triplet + A response including a hash tag corresponding to α is returned to the receiving device 30. Also, the hash tag RA unit 21 refers to the hash tag DB unit 22 in response to a DVB-Triplet + α search request corresponding to the hash tag from the receiving device 30 using the search WebAPI, and corresponds to the hash tag. A response including DVB-Triplet + α is returned to the receiving device 30.

The receiving device 30 is capable of receiving a TV broadcast such as a television receiver, for example, a tuner 31 for receiving a DVB standard TV broadcast broadcast from the broadcasting device 20, and a Twitter for using a Twitter service. (Twitter) Has an application 32.

The tuner 31 receives and plays MPEG2TS as a DVB standard TV broadcast, and outputs content video and audio. Further, the tuner 31 extracts DVB-SI from the received MPEG2TS and supplies it to the twitter application 32.

The Twitter application 32 has a general function as an application using the Twitter service, that is, posts a short sentence (tweet) input by the user to the Twitter server 13 or acquires a tweet posted on the Twitter server 13. Or display a list.

Furthermore, the Twitter application 32 acquires DVB-SI corresponding to the content that the user is viewing (the tuner 31 is receiving) from the tuner 31, extracts DVB-Triplet + α, and hashes including the DVB-Triplet + α A tag request query is generated and transmitted to the hash tag RA unit 21. Further, the hash tag included in the response returned from the hash tag RA unit 21 in response to the hash tag request query is added to the tweet input by the user and posted to the twitter server 13.

Also, the Twitter application 32 generates a DVB-Triplet + α request query including the one specified by the user from the hash tags added to the tweet displayed in the list, and transmits it to the hash tag RA unit 21. Further, tuning of tuner 31 is controlled by notifying tuner 31 of DVB-Triplet + α included in the response returned from hash tag RA unit 21 in response to the DVB-Triplet + α request query.

Thereby, the receiving device 30 receives and displays the content of the TV broadcast and simultaneously accesses the Twitter server 13. Thereby, the user can post the topic of the content as a tweet while viewing the content. In addition, it is possible to select a channel so that content that is a topic on Twitter can be received.

[Second configuration example of Twitter support system]
Next, FIG. 4 is a block diagram showing a second configuration example of the Twitter support system. In the first configuration example shown in FIG. 1, the receiving device 30 has the tuner 31 and the tweeter application 32. However, in the second configuration example, these are mounted on different devices.

That is, in the second configuration example, the receiving device 50 has a tuner 51 for receiving a DVB standard TV broadcast broadcast from the broadcasting device 20, and the terminal device 60 is a Twitter for using the Twitter service. (Twitter) Has an application 61.

For example, a TV receiver or the like is assumed as the receiving device 50, and a tablet terminal, a slate PC, a mobile phone, a smartphone, or the like is assumed as the terminal device 60. It is assumed that the receiving device 50 and the terminal device 60 form a home network by a wireless LAN or the like.

The other constituent elements in the second configuration example in FIG. 2 are the same as those in the first configuration example and are given the same reference numerals, and thus the description thereof is omitted.

[Description of processing for registering DVB-Triplet + α of content in hashtag DB unit 22]
Next, FIG. 4 is a flowchart for explaining processing for registering DVB-Triplet + α of content in the hash tag DB unit 22.

In step S11, the broadcasting device 20 organizes content to be broadcast in the future, and generates DVB-SI corresponding to the content. Furthermore, the broadcasting device 20 extracts DVB-Triplet + α from the DVB-SI.

In step S12, the broadcasting device 20 calls the registration WebAPI to supply the DVB-Triplet + α to the hash tag RA unit 21 and register it in the hash tag DB unit 22. At this time, a content ID and a hash tag can also be registered in association with DVB-Triplet + α. Thereafter, in step S13, the broadcast device 20 broadcasts DVB-SI together with the content.

On the other hand, in step S21, the hash tag RA unit 21 registers one or more DVB-Triplet + α corresponding to one content in the hash tag DB unit 22 in response to the calling of the WebAPI from the broadcasting device 20. Further, when the broadcast apparatus 20 is notified of the content ID and the hash tag together with the DVB-Triplet + α, the hash tag RA unit 21 associates them with the DVB-Triplet + α and registers them in the hash tag DB unit 22. .

Furthermore, the hash tag RA unit 21 additionally registers the hash tag notified from other than the broadcasting device 20 in the hash tag DB unit 22 in step S22.

Here, the WebAPI for DVB-Triplet + α registration will be explained in detail.

For example, as shown below, the registration WebAPI has a format in which one or more DVB-Triplet + α, a content ID, and one or more hash tags are arranged in order in a query character string of http-get.
http://www.hashTagRA.com/RegistrationAuthority/set?dvbUrl=
”Dvb: //8468.12634.18.333,dvb: //8468.12634.18.444”
& contentId = ”123”
& hashTag = ”# nkh_akashiro, # uta_kassen”

The hash tag RA unit 21 is provided with a search Web API and a delete Web API in addition to the DVB-Triplet + α registration Web API described above.

The Web API for searching DVB-Triplet + α has a format that specifies DVB-Triplet + α, content ID, or hash tag, for example, as follows.
http://www.hashTagRA.com/RegistrationAuthority/getAll?contentId=123

The http response of the hash tag RA unit 21 in response to the search Web API call is, for example, as follows.
dvbUrl = ”dvb: //8468.12634.18.333,dvb: //8468.12634.18.444”
& contentId = ”123”
& hashTag = ”# nkh_akashiro, # uta_kassen”

The Web API for erasing DVB-Triplet + α has a format that specifies DVB-Triplet + α, content ID, or hash tag, for example, as follows.
http://www.hashTagRA.com/RegistrationAuthority/deleteAll?contentId=123

The hash tag RA unit 21 deletes the corresponding information registered in the hash tag DB unit 22 by calling the Web API for deletion.

This completes the description of the process of registering the content DVB-Triplet + α in the hash tag DB unit 22.

[Description of processing when using the Twitter service while viewing content in the first configuration example]
FIG. 6 is a flowchart for explaining processing (hereinafter referred to as viewing tweet processing in the first configuration example) when using the Twitter service while viewing content in the first configuration example.

In step S31, the receiving device 30 starts receiving and playing back the content by the tuner 31 and activates the twitter application 32 in accordance with a predetermined operation from the user. As a result, the user can use the Twitter service while viewing the content.

In step S32, the Twitter application 32 stands by until a tweet is input by the user who is viewing the content. If a tweet is input, the process proceeds to step S33.

In step S33, the tweeter application 32 acquires DVB-SI corresponding to the content being received from the tuner 31 and being reproduced. Further, the tweeter application 32 extracts DVB-Triplet + α from the DVB-SI. In step S34, the twitter application 32 requests a hash tag corresponding to the extracted DVB-Triplet + α by calling the search WebAPI of the hash tag RA unit 21.

For example, the search WebAPI is as follows.
http://www.hashTagRA.com/RegistrationAuthority/getHashtag? dvbUrl = ”dvb: //8468.12634.18.333”

In accordance with the search WebAPI, in step S41, the hash tag RA unit 21 refers to the hash tag DB unit 22 and generates the following http response including a hash tag corresponding to DVB-Triplet + α to generate a Twitter. Reply to the application 32.
hashTag = ”# nkh_akashiro, # uta_kassen”

In step S35, the twitter application 32 adds the hash tag included in the response to the tweet confirmed by the user in the process of step S32 and posts it to the twitter server 13. When the response includes a plurality of hash tags, the user may be allowed to select one of the plurality of hash tags to be added to the tweet.

In response to the posting of a tweet from the Twitter application 32, in step S51, the tweeter server 13 publishes the posted tweet, filters all the tweets with the hash tag of the tweet, and transmits the result to the tweet application 32. . In step S36, the twitter application 32 browses the tweet transmitted from the twitter server 13.

Thereafter, in step S37, the tweeter application 32 determines whether or not its own end is instructed by the user, and repeats steps S32 to S37 until the end is instructed. When the termination is instructed, the viewing tweet process of the first configuration example is terminated.

According to the viewing tweet processing of the first configuration example described above, the user can post a tweet corresponding to the content being viewed without giving an appropriate hash tag by himself / herself. Tweets posted in this way are accurately collected as tweets related to the same content by the broadcasting station or the like.

[Explanation of processing when tweet becomes content viewing lead in first configuration example]
Next, FIG. 7 is a flowchart for explaining processing when a tweet becomes a content viewing lead in the first configuration example (hereinafter referred to as viewing guidance processing in the first configuration example).

In step S133, the tweeter application 61 requests DVB-Triplet + α corresponding to the identified hash tag by calling the search WebAPI of the hash tag RA unit 21. In response to the search WebAPI, in step S151, the hash tag RA unit 21 refers to the hash tag DB unit 22, generates an http response including DVB-Triplet + α corresponding to the hash tag, and returns the response to the Twitter application 61. To do.

In step S134, the twitter application 61 notifies the tuner 51 of DVB-Triplet + α included in the response, and requests reception and playback of content corresponding to DVB-Triplet + α. In response to this request, in step S161, the tuner 51 analyzes DVB-Triplet + α, specifies the original network identifier Onid, the transport identifier Tsid, the service identifier Sid, and the event identifier Eid, and receives the corresponding content. , Start playback.

Thereafter, in step S135, the twitter application 61 determines whether or not the user has instructed to end the process, and repeats steps S132 to S135 until the end is instructed. When the termination is instructed, the viewing guidance process of the second configuration example is terminated.

According to the viewing guidance process of the second configuration example described above, the user receives the content currently being broadcast on the Twitter service used by using the terminal device 60, and the receiving device 50. You can watch at. In addition, the broadcast station side can guide the user of the Twitter service to view the content by enlarging tweets about the content to be broadcast.

In this embodiment, the case where viewing is guided to the content being broadcast has been described. However, DVB-Triplet + α included in the response corresponds to content that has already been broadcast or has not yet been transmitted. It may correspond to broadcast content. Therefore, when DVB-Triplet + α corresponds to a broadcasted content, for example, the content is guided to a service that distributes the content by streaming. Also, if DVB-Triplet + α corresponds to unbroadcast content, for example, the recording reservation setting for the content is performed.

[Example of Screen Display of Receiving Device 30]
FIG. 10 shows a display example when the receiving device 30 simultaneously displays the content video and the Twitter service video on the screen.

As shown in FIG. 3A, the screen 80 is provided with a content display area 81, a tweet display area 82, and a tweet input area 83. Further, the screen 80 is provided with hash tag selection buttons 84-1 and 84-2 and an update button 85.

In the content display area 81, the video of the content being received and reproduced by the tuner 31 is displayed. In the tweet display area 82, posted tweets transmitted from the Twitter server 13 are displayed. The tweet input area 83 is for a user to input a tweet. The hash tag selection buttons 84-1 and 84-2 are used to select a hash tag to be added to a tweet. The update button 85 is for instructing posting of the input tweet to the Twitter server 13.

As shown in FIG. B, when a character string (tweet) is input to the tweet input area 83 by the user, a hash tag corresponding to DVB-Triplet + α of the content being received and reproduced is received from the hash tag RA unit 21. Acquired and the hash tag character string is displayed on the hash tag selection buttons 84-1 and 84-2.

Then, as shown in FIG. C, even if at least one of the hash tag selection buttons 84-1 and 84-2 is selected, the hash tag is added to the tweet. When the update button 85 is operated in this state, the tweet input in the tweet input area 83 is posted to the twitter server 13.

[Modification]
In the viewing guidance processing of the first and second configuration examples described above, the user is guided to view the content being broadcast, but the content being talked about by the tweet that has already been raised has already been broadcast. In some cases, it is not broadcast. Therefore, when the DVB-Triplet + α included in the response corresponds to the broadcasted content, for example, the content is guided to a service that distributes the content. Also, if DVB-Triplet + α corresponds to unbroadcast content, for example, the recording reservation setting for the content is performed.

Also, in this embodiment, DVB-Triplet + α is extracted from DVB-SI corresponding to the content as information for uniquely identifying the content being broadcast. Instead, for example, it may be distributed from a predetermined server via the Internet. In such a case, the url of the predetermined server may be used instead of DVB-Triplet + α as information for uniquely specifying the content.
