- the present invention relates to an information providing apparatus and an information providing method for presenting information for supporting selection of content viewing and other value-added information to a user who records, schedules or views a broadcast content
- the present invention relates to an information providing apparatus and an information providing method for providing viewing selection information and other value-added information in which a user's preference has become apparent based on a user's viewing history and the like, and a computer program.
- Background art
- Broadcasting technology encompasses a wide range of technologies, including signal processing, transmission and reception, and audio and video information processing.
- signal processing transmission and reception
- audio and video information processing there are various transmission modes for providing program contents to users, such as a broadcast system using radio waves such as terrestrial waves and satellite waves, a cable television system, and a net program provided using computer communication.
- the penetration rate of television is extremely high and is installed in almost all homes, and broadcast contents distributed from each broadcast station are viewed by an unspecified number of people.
- Another form of viewing the broadcast content is to record the received content on the viewer side and reproduce it at a desired time.
- PCs Personal recorders
- the HDD is a device capable of random access to recording data. Therefore, when playing back recorded content, it is not necessary to simply play back the recorded program from the beginning like a conventional video tape, and it is not necessary to simply play back the recorded program (or a specific program in the program). Scenes or specific corners).
- a viewing mode in which a receiver (TV or video recording / playback device) equipped with a large-capacity storage such as a hard disk device is used to receive broadcast content, temporarily store it in the receiver, and then play it back. Called "server-type broadcasting.”
- video and audio are distributed in advance so that they can be viewed only in real time, such as ordinary television reception, so that they can be viewed from a specified time, or information that is distributed simultaneously. For example, it is possible to perform scene search and digest viewing by using such methods.
- EPG electronic program guide
- the CE device such as an HDD recorder acquires an EPG in parallel with the recording processing of a broadcast program, and presents the EPG when a user plays and views the recorded program. A support effect can be obtained.
- EPG systems include VBI (Vertical Blanking Interval) type (see, for example, Patent Document 1) and digital direct satellite broadcasting (DSS: Digital Satellite System (trademark of Hughes Communication)). Digital satellite system (for example, see Patent Document 2).
- VBI Very High Frequency
- the VBI data constituting the EPG is located at a position on the horizontal scanning line where the original image is not affected. Import and transmit.
- display data of the electronic program guide can be generated from the VBI data and displayed on the monitor.
- EPG data is digitized together with the original image data, and then packetized and transmitted.
- this EPG data is stored in the memory, the corresponding display data is generated, and displayed on the monitor.
- a program guide display device that can display a program guide that allows a user to efficiently recognize a program that the user particularly wants to view even when there are many programs that match the user's preference has been proposed (eg, , Patent Document 3).
- EPG data of a plurality of programs is stored, EPG data is searched using the EPG data storage unit 102 and a keyword for program search input by the user, and the program detected by the search is searched. Is created and displayed based on the evaluation information for each keyword.
- the user sets keywords (for example, program titles, contents, performers, etc.) representing his / her preferences (for specifying a program to be viewed), and broadcast content that hits the keyword is set.
- keywords for example, program titles, contents, performers, etc.
- his / her preferences for specifying a program to be viewed
