Description

  The present invention relates to a display device, a recommendation server, and a program for displaying a content guide on a display. The content guide is a program guide that allows a user to view and select a desired program, and is displayed on a display such as a television device.

According to the digital broadcasting service, content distribution forms are roughly divided into the following two types.
(1) Broadcast content that depends on the broadcast time (2) On-demand content that does not depend on the broadcast time

  There is a “content guide” as a display image of a guide role that allows the user to understand the outline of a plurality of contents at a glance and to view and select one of the contents. As a content guide, an “electronic program guide” or “EPG (Electronic Program Guide)” displays a schedule of broadcast-type content, and allows desired content to be viewed and selected. The “on-demand content guide” displays a list of on-demand content, and allows the user to view and select desired content.

  According to broadcast-type content (for example, referred to as “linear TV”), the user browses the content guide in order to confirm the broadcast time. The content guide is an electronic version of a broadcast time schedule (for example, referred to as a “late field”) found in newspapers or magazines. This is because the user can easily view and select a channel for a desired program by browsing the content guide (see, for example, Patent Document 1).

  As a content guide for broadcast-type content, for example, there is a technique for displaying a grid-like cell in which the horizontal axis is time and the vertical axis is a channel number (see, for example, Patent Document 2). In the cell, description of contents such as a program title is described. According to this technique, when one cell (first subset) specified by time and channel number is selected, a plurality of time cells (second subset) are further displayed in the cell. The user can view and select desired content from these time cells.

  On the other hand, according to the on-demand type content, when the user designates the address of the desired content with respect to the content reproduction apparatus, streaming of the content is distributed from the content server. In practice, the content address is given by the system when the user selects the content on the on-demand content guide. When the content reproduction apparatus transmits a request to the address of the content server via the network, the content server distributes from the top of the content (startover). Therefore, according to the on-demand content, the user only needs to search for the desired content from the on-demand content guide, and does not need to recognize the time and channel number.

JP 2008-193418 A Japanese Patent No. 4108522

Nikkei Trendy Net, “Video distribution for TV“ AcTVila ”, the degree of fullness and availability of programs of interest”, [online], [searched August 26, 2009], Internet <URL: http: // trendy. nikkeibp.co.jp/article/column/20080206/1006845/?SS=expand-digital&FD=764014590>

  The user is required to browse different content guides when searching for desired broadcast-type content and when searching for desired on-demand content. Since these different types of contents are conceptually completely different in delivery form, there is no technique for browsing these contents collectively using a content guide.

  In the case of a broadcast-type content guide, all programs scheduled to be broadcast and available content are listed regardless of the user's intention to view. The user needs to search for desired content from a large amount of information based on the broadcast time and channel number.

  For on-demand content, a content guide that displays a list of available content is used. For example, according to the technique described in Non-Patent Document 1, a content guide for on-demand content is realized. When a large number of contents of 50 or more are displayed in the content guide as in this example, it takes a long time for the user to reach the desired content, and eventually it may not be found. This is based on the fact that conventional on-demand content guides are hierarchical menus that narrow down items such as “performer”, “title of work”, and “genre”. Therefore, the user himself / herself must find desired content while narrowing down the items little by little.

  Furthermore, assuming a content guide that integrates broadcast-type content and on-demand content, the amount of information becomes extremely large, and it is extremely difficult for a user to browse and search for desired content.

  Accordingly, the present invention provides a display device that displays on a display one content guide that allows a user to easily select a content that is highly viewable without distinguishing a plurality of different types of content.

  FIG. 1 is a system configuration diagram according to the present invention.

  According to FIG. 1, a display device 1 such as a television device or a mobile phone is equipped with a display 101. The user can view and select desired content by browsing the content guide displayed on the display 101. The content selected for viewing by the user is reproduced and displayed on the display 101.

  According to FIG. 1, a broadcast station 2 and a content server 3 are represented as content distribution sources for the display device 1. The broadcast station 2 distributes broadcast content, and the content server 3 distributes on-demand content or broadcast content. In the following description, it is assumed that the content server 3 distributes on-demand content.

  Broadcast content includes those based on terrestrial digital broadcast, satellite digital broadcast, cable television broadcast, or IP broadcast. Here, the broadcastable content that can be viewed is content that can be reproduced at the present time or content that can be reproduced at a future time. That is, even content that can be played back in the future can be displayed in the content guide in advance. On-demand content may be based on video on demand or Internet video (for example, YouTube (registered trademark)).

  A television device as the display device 1 has an antenna for receiving broadcast waves and can receive broadcast-type content from the broadcast station 2. The television apparatus is connected to a home network and is connected to an access network and the Internet via a router. Accordingly, the television apparatus can receive on-demand content from the content server 3.

Further, the mobile phone can connect to a mobile phone network and the Internet via a base station and receive on-demand content from the content server 3.

  According to FIG. 1, the recommendation server 4 is further connected to the Internet. The recommendation server 4 recommends and extracts broadcast-type content and on-demand type content that are highly viewable based on the preference keyword and / or viewing history keyword for each user. The recommendation information is transmitted from the recommendation server 4 to the display device 1 possessed by the user.

  FIG. 2 is a first functional configuration diagram of the display device according to the present invention.

  According to FIG. 2, the display device 1 includes a display unit 101, a user operation unit 102, a broadcast receiving unit 103, a communication interface unit 104, and a content storage unit 111. Also, “the existence of the content is well known and the content with high possibility of viewing that matches the user's preference” is set as the first content, and “the existence of the content is not well known, The “highly relevant content” is set as the second content. According to FIG. 2, for example, the first content will be described as broadcast content, and the second content will be described as on-demand content. Of course, both the first content and the second content may be broadcast content or on-demand content. The difference in information source between the first content and the second content is not limited to only the broadcast type / on-demand type.

  The display unit 101 displays a content guide and reproduces and displays the content according to a user operation. According to the present invention, there is a feature in the display configuration of the content guide for allowing the user to select and view the content.

  The user operation unit 102 receives a user operation. When the display device 1 is, for example, a television device, the user operation unit 102 may receive an infrared operation signal from a remote operation device (remote control device) possessed by the user. Further, when the display device 1 is, for example, a mobile phone, the user operation unit 102 may be a numeric keypad or a soft key pressed by the user.

  The broadcast receiving unit 103 receives the broadcast content (first content) of the broadcast station (first information source) 2. The broadcast receiving unit 103 receives content based on channel settings from among a plurality of contents that can be received at the current time via broadcast waves. The received broadcast content is output to the content storage unit 111.

The received on-demand content is output to the content storage unit 111. Further, the communication interface unit 104 receives recommendation information from the recommendation server 4.

  The content accumulation unit 111 accumulates both broadcast-type content (first content) and on-demand content (second content). The content storage unit 111 may temporarily record broadcast-type content or streaming on-demand content in a cache memory, or permanently store it in a recording device such as a hard disk. You may do. Since the content storage unit 111 functions as a cache memory, it is possible to reproduce the broadcast wave or data flowing from the server while receiving it in a streaming manner.

  Further, according to FIG. 2, the display device 1 includes a first content extraction unit 112, a second content extraction unit 113, a content guide display unit 114, a content reproduction control unit 115, and a viewing history transmission unit 116. And have. These functional components are realized by executing a program that causes a computer mounted on the display device to function.

  The first content extraction unit 112 recommends and extracts broadcast-type content (first content) that is highly viewable for the user from among a plurality of broadcast-type content that can be viewed at the current time by the broadcast receiving unit 103. To do. The first content here is, for example, “content such as a popular program of terrestrial broadcasting that is well known in advance to be broadcast and that has a high possibility of viewing that matches the user's preference”. It is. Of course, it may be already stored in the content storage unit 111.

  At this time, it is also preferable that the first content extraction unit 112 extracts a plurality of broadcast-type contents in the priority order according to the viewability. Specifically, the first content extraction unit 112 recommends and extracts one or more channel numbers that can be received at the current time via broadcast waves.

  Here, the first content extraction unit 112 may extract the first content based on the user's preference keyword or viewing history keyword. For example, a plurality of broadcast contents having the preference keyword “cooking” are recommended and extracted. Also, for example, based on the viewing history of the user “viewing broadcast content of channel number 1 every Thursday at 20:00”, the broadcast content of channel number 1 is recommended and extracted at that time.

  Further, the first content extraction unit 112 may extract the first content according to the recommendation information received from the recommendation server 4. The recommendation server 4 instructs broadcast-type content that is likely to be viewed by the user based on the user's preference keyword and viewing history keyword.

  The second content extraction unit 113 is related to the broadcast-type content (first content) extracted by the first content extraction unit 112 from the plurality of on-demand content that can be viewed by the communication interface unit 104. One or more on-demand contents (second contents) to be recommended are extracted. The second content here is, for example, “content whose existence is not well known but highly relevant to the first content”. Of course, it may be already stored in the content storage unit 111.

  For example, the second content extraction unit 113 recommends and extracts a plurality of on-demand contents having the keyword “recipe” of the broadcast contents. At this time, it is also preferable that a plurality of on-demand contents are extracted in order of priority according to relevance. Specifically, the second content extraction unit 113 recommends and extracts the address of the content that can be provided from the content server 3.

  The content guide display unit 114 displays a first icon for viewing selection of the extracted broadcast-type content (first content), and selects the selected on-demand content (adjacent to the first icon). A second icon for viewing selection of (second content) is displayed.

  According to FIG. 2, first, after the broadcast type content is recommended and extracted, the related on-demand content for the broadcast type content is recommended and extracted. Generally, users have been familiar with the “late field” of newspapers and magazines for a long time. Therefore, in many cases, the user views and selects a desired channel from among terrestrial broadcast-type programs having only a few channels. Eventually, the content that the user wants to view tends to be biased toward terrestrial broadcast content.

  Conversely, on-demand services provide many contents on the Internet in addition to those provided by cable television operators and telecommunications carriers. Therefore, although the number of usable contents is enormous, an efficient content viewing selection technique by a user has not been provided, and its spread has not progressed.

  Therefore, according to FIG. 2, the content guide displayed by the content guide display unit 114 is adjacent to the first icon of the terrestrial broadcast-type content that is easy for the user to view and select. Display the icon.

  The viewing history transmission unit 116 transmits, to the recommendation server 4, a viewing history keyword whose content has been selected for viewing by the user. The viewing history is also transmitted to the first content extraction unit 112 and the second content extraction unit 113.
