Description

  The present invention relates to a television program data reproduction control system, a television program data transmission device, an advertisement server, a television program data reproduction control method, and a program.

  In recent years, DLNA (Digital Living Network) that enables HDDs (Hard Disk Drive) recorders and home appliances to be connected to a TV using a home network so that the information held by the HDD recorder and home appliances can be viewed on the TV. A standard called Alliance is drawing attention. In DLNA, an information provider such as an HDD recorder or home appliance is called a digital media server (DMS: Digital Media Server), and a television is called a digital media player (DMP: Digital Media Player). The name will be used.

  In DLNA, the DMS stores a title list of contents and details of each content. The DMP has a function of searching for a DMS that can be communicated, and acquires and displays a title list from the searched DMS. When the user selects a specific title using operation means such as a remote controller, the DMP acquires the content related to the title from the DMS, and reproduces and outputs it.

By the way, the applicant has recently developed a technique (referred to as W-DLNA) for connecting DLNA to an external network (see Non-Patent Document 1). According to this, a DMS (W-DLNA home gateway module) connected to an external server through a communication line is prepared in the home. This DMS acquires a title list of contents possessed by the external server. The DMP handles this title list in the same way as the title list held by other DMSs in the house and displays it to the user. When the user selects one of these titles, the DMP requests the DMS to obtain the selected content. Upon receiving this request, the DMS goes to acquire content from the external server and transfers the acquired content to the DMP.
KDDI R & D Laboratories, Inc., “Development of Wide-area Technology for Information Appliances (W-DLNA)”, [online], December 19, 2006, [March 26, 2007 search], Internet <URL: http : //www.kddilabs.jp/pr_pdf/20061219DLNA.pdf>

  One of the usage modes of W-DLNA is to use an external server as a DMS in another user's home. Hereinafter, the DMS that provides the content is referred to as DMS-A1, the owner user is referred to as user A, and the W-DLNA home gateway module in the user A's home is referred to as DMP-A2. The DMP that receives content from the user A is DMP-B, the owner user is the user B, and the W-DLNA home gateway module in the user B's home is DMS-B.

  User A instructs DMP-A2 to provide the content in DMS-A1 to user B. Then, DMP-A2 acquires a title list of contents in DMS-A1, establishes a SIP (Session Initiation Protocol) session with DMS-B, and acquires the acquired title list to DMS-B. Send. User B confirms the title list in DMP-B and selects one of them. Then, DMS-B acquires the content related to the title selected from DMS-A1 via DMP-A2, and transfers it to DMP-B. The DMP-B reproduces and outputs the content thus transferred.

  However, when the content transferred from the user A's home to the user B's home is a recorded product of a television program, the following problem occurs with respect to the advertisement (CM: Commercial Message) included therein.

  The first is a regional problem. If the areas where user A's house and user B's house are different, advertisements in different areas will be viewed at user B's house. This is not desirable for corporate advertising strategies.

  The second is a time issue. At user B's home, content is viewed after television broadcasting, and advertisements that are no longer old are viewed. This is also not preferable for the corporate advertising strategy. Note that the same can be said about this problem when the user B views a TV program recorded by himself / herself later.

  Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a system configuration diagram of a W-DLNA system 1 including a television program data reproduction control system according to the present embodiment.
As shown in the figure, the W-DLNA system 1 includes a home network 10, an HDD recorder 11 connected thereto, and a W-DLNA home gateway module 12 (hereinafter referred to as a gateway 12) in the user A home. In addition, the user B's home includes a home network 20, a television 21 connected thereto, and a W-DLNA home gateway module 22 (hereinafter referred to as a gateway 22), and a SIP server 31 connected to the Internet 30 and An advertisement server 32 is included. The television program data reproduction control system includes the gateway 22 and the advertisement server 32 among these components. In the following description, it is assumed that user A's home is in Nagoya and user B's home is in Tokyo.

First, each component in the user A home will be described. The home network 10 includes a transmission medium such as a LAN cable or radio, and a connection device such as a hub or a router.
The HDD recorder 11 is a television program recording device that functions as the above-described DMS. Specifically, it has a function of receiving and recording a TV program, and includes a title of the recorded TV program and TV program data that is moving image data (more specifically, MPEG data) of a finite time as the content. I remember it. When the DMP (for example, a gateway 12 described later) requests a title list, the HDD recorder 11 transmits the stored TV program title list to the DMP. Further, in the DMP, when the user selects one of the titles included in the title list, the television program data related to the selected title is transmitted to the DMP. In the present embodiment, the selection of the title by the user is performed not on the gateway 12 as the DMP but on the television 21 as the DMP. Details thereof will be described later.

  The gateway 12 is a recorded television program data transmission device that functions as the above-described DMP. The gateway 12 is implemented as an application in a broadband router or a set top box.

  The gateway 12 acquires television program data recorded on the HDD recorder 11 via the home network 10. Further, it is connected to the Internet 30 and transmits TV program data acquired from the HDD recorder 11 to the gateway 22 described later.

  Details of a procedure when the gateway 12 transmits the television program data will be described. Here, an example in which the gateway 12 and the gateway 22 establish a SIP session using the SIP server 31 will be described. First, the gateway 12 receives input of identification information (described later) of the transmission destination of television program data from the user. And the identification information input with respect to the SIP server 31 is transmitted.

  The SIP server 31 stores identification information and an IP address in association with each device connected to the Internet 30. The identification information is determined in advance for each IP address stored in the SIP server 31. As specific identification information, for example, numerical information such as a telephone number is preferably used.

  When the SIP server 31 receives the identification information from the gateway 12, the SIP server 31 returns an IP address stored in association with the identification information. The gateway 12 performs a predetermined negotiation process with the returned IP address, that is, the gateway 22. When the negotiation process is completed, a SIP session is established between the gateway 12 and the gateway 22.

  When the SIP session is established, the gateway 12 first transmits the title list acquired from the HDD recorder 11 to the gateway 22. The gateway 22 that has received the title list returns selected title information indicating the title selected by the user (described later). Upon receiving the selected title information, the gateway 12 acquires the television program data of the title indicated by the selected title information, and transmits the IP address returned from the SIP server 31 as the destination.

Next, each component in the user B home will be described. The home network 20 includes a transmission medium such as a LAN cable or wireless and a connection device such as a hub or a router.
The television 21 is a television program reproduction output device that functions as the above-described DMP. Specifically, the television 21 has a function of searching for a DMS that can communicate (for example, a gateway 22 described later), and requests the searched DMS to transmit a title list. When a title list is received in response to this request, the received title list is reproduced and output using a display device such as a cathode ray tube, a liquid crystal display, a plasma display, and a speaker. The television 21 is configured to include operation means including a remote controller. When the user selects a specific title using the operation means, the selected title information indicating the title is transmitted to the DMS. When the DMS transmits the TV program data according to the selected title information, the TV 21 receives the TV program data, and reproduces and outputs it using the display device and the speaker.

  The gateway 22 is a television program data transmission device that functions as the DMS. The gateway 22 is implemented as an application in a broadband router or a set top box.

  The gateway 22 receives the title list from the gateway 12 and stores it. Then, when there is a request from the television 21, the stored title list is transmitted to the television 21. As a result, when the selected title information is received from the television 21, the gateway 22 transmits the selected title information to the gateway 12. As a result, since the television program data is received from the gateway 12, the gateway 22 transmits the received television program data to the television 21. This television program data is reproduced and output by the television 21.

  The TV program data recorded at the user A's home and reproduced and output on the TV 21 at the user B's home as described above may include advertisement data. In the present embodiment, this advertisement data is replaced with advertisement data suitable for the region where the user B is located (reproduction region) and the date and time (reproduction date and time) that the user B views. Hereinafter, the configuration for that purpose will be described in detail.

  FIG. 2 is a schematic block diagram showing functional blocks of a television program data reproduction control system included in the W-DLNA system 1. As shown in the figure, the gateway 22 includes a television program data receiving unit 221, an advertisement data receiving unit 222, and a playback control unit 223. Note that the playback control unit 223 includes a replacement unit 2230 therein. The advertisement server 32 includes a reproduction status information acquisition unit 321, an advertisement data selection unit 322, and an advertisement data storage unit 323.

  The advertisement data storage unit 323 functions as an advertisement data storage unit that stores a large number of advertisement data. Each advertisement data is moving image data (more specifically, MPEG data) having a finite time length, like television program data. The advertisement data storage unit 323 stores each advertisement data in association with a region and a period (a period specified by the date and time zone) in which the advertisement data is to be reproduced. Table 1 shows a specific storage example of the advertisement data storage unit 323. Note that the content stored in the advertisement data storage unit 323 is updated by, for example, a television station.

  The playback status information acquisition unit 321 functions as playback status information acquisition means for acquiring playback status information including at least one of the playback area and playback date and time of a TV program by the television 21. In a specific example, when transmitting the television program data to the television 21, the playback control unit 223 of the gateway 22 includes, for each television program data, regional information indicating the region (Tokyo) where the user B's home is located, Current time information indicating the current time is transmitted to the advertisement server 32. The reproduction status information acquisition unit 321 receives the area information and the current time information transmitted in this way, and acquires them as reproduction status information.

  The advertisement data selection unit 322 selects one or a plurality of advertisement data from the advertisement data stored in the advertisement data storage unit 323 based on the playback status information acquired from the playback status information acquisition unit 321. Specifically, the advertisement data is stored in association with the area information included in the reproduction status information, and is stored in association with the period including the current time indicated by the current time information included in the reproduction status information. One or more advertisement data are selected. In addition, although the example using both area information and present time information is demonstrated here, of course, you may use only one side. The advertisement data selection unit 322 transmits the selected one or more advertisement data to the gateway 22. Thus, the advertisement data selection unit 322 functions as an advertisement data selection unit.

  The TV program data receiving unit 221 functions as a TV program data receiving unit that receives TV program data from the gateway 12. The reproduction control unit 223 transmits the television program data acquired in this way to the television 21. The details of these processes are as described above. At this time, the reproduction control unit 223 transmits the area information and the current time information to the advertisement server 32 as described above.

  The advertisement data receiving unit 222 functions as an advertisement data receiving unit that receives one or a plurality of advertisement data from the advertisement server 32. The advertisement data receiving unit 222 outputs the received one or more advertisement data to the replacement unit 2230.

  When the playback control unit 223 transmits the TV program data, the replacement unit 2230 receives one or a plurality of advertisement data (advertisement data broadcast in the past in the Nagoya area) received by the advertisement data reception unit 222. It functions as a replacement means for replacing the one or more advertisement data (advertisement data to be aired in the Tokyo area). Specifically, an advertisement data portion in the television program data to be transmitted is detected, and the portion is replaced with the one or more advertisement data received by the advertisement data receiving unit 222. As a result of the replacement performed by the replacement unit 2230, the television 21 reproduces and outputs television program data including the replaced advertisement data.

  FIG. 3 is a diagram illustrating an example of television program data. As shown in the figure, the television program data is data including a main data portion and an advertisement data portion alternately. The replacement unit 2230 detects the advertisement data portion and replaces it with the one or more advertisement data received by the advertisement data receiving unit 222. For the detection of the advertisement data portion, for example, the volume difference between the main data portion and the advertisement data portion can be used. In this case, the replacement unit 2230 detects the advertisement data portion by detecting a change in volume.

As described above, according to the television program data reproduction control system, when a television program is reproduced and output at user B's home, an advertisement suitable for the region (reproduction region) where user B's home is located can be provided. It becomes possible. It is also possible to provide an advertisement suitable for the date and time (viewing date and time) that the user B views.
In addition, when the TV program data recorded at user A's home is played back at user B's home, the advertisement data therein can be replaced.

  Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and the present invention can of course be implemented in various modes without departing from the scope of the present invention. It is.

  For example, when transmitting the regional information and the current time information to the advertisement server 32, the gateway 22 uses the TV program identification information that can uniquely identify the title of the TV program to be reproduced or the TV program in Japan. It is good also as transmitting. The advertisement data storage unit 323 stores the advertisement data in association with the television program title or television program identification information, and the advertisement data selection unit 322 associates the advertisement data with the received television program title or television program identification information. It is good also as selecting the advertisement data memorize | stored. In this way, it is possible to cause the television 21 to reproduce and output appropriate advertisement data not only according to the reproduction region / reproduction date but also according to the television program production circumstances (sponsor etc.).

  Further, when transmitting the regional information and the current time information to the advertisement server 32, the gateway 22 transmits the advertisement time length information indicating the time length of the advertisement data included in the television program data to be reproduced together. It is good. And the advertisement data selection part 322 is good also as selecting the advertisement data for the received time length. In this way, the advertisement server 32 can transmit only the minimum necessary advertisement data to the gateway 22.

  The present invention is applicable not only to the case where a TV program recorded by the user A is transferred to the user B at a later date, but also to so-called streaming transmission in which the user A transfers the TV program data to the user B in real time. Is possible.
