Embodiment Construction

[0055] figure 1 is a schematic diagram showing a typical structure of a content suggestion system applicable to the present invention. exist figure 1 , the delivery server 3 acquires streaming data from the streaming database 1, and delivers the acquired data to the client device 5 via a network 6, such as the Internet or other suitable network. The delivery server 3 also obtains metadata related to the content from the metadata database 2 , and supplies the obtained data to the content suggestion server 4 via the network 6 .

[0056] Such as figure 2 As shown, the metadata consists of items representing content attributes such as "broadcast start time", "broadcast end time", "broadcast station", "genre", "title", "person" , Subtitle, and Keywords.

[0057] As far as grouping items including at least one such attribute item are concerned, the content suggestion server 4 provides the same group ID to its constituent items (i.e., those contents that generate the grouping it...

Abstract

An information processing device and method, a recording medium, and a program for appropriately generating preference information based on frequently viewed programs and infrequently viewed programs and suggesting programs corresponding to user preferences. A preference information extraction section (101) extracts preference information based on metadata on a program and records a program browsing history. The preference information of the program viewed for the first time is recorded as the specific program preference information. In addition, user preference information is generated based on program preference information of programs whose number of views exceeds a threshold. A control section (103) sets a schedule for automatic recording of programs whose number of views exceeds a threshold. When the reservation of automatic recording is canceled, the preference information update section (102) modifies the user preference information based on the metadata of the program whose reservation has been cancelled.

Description

technical field [0001] The present invention relates to an information processing device, an information processing method, a recording medium and a program. More specifically, the present invention relates to an information processing device, an information processing method, a recording medium, and a program for efficiently and powerfully suggesting content. Background technique [0002] There is a content suggestion system capable of searching for delivered content that meets user preferences and providing the user with information related to the content thus detected (one such system is disclosed in Japanese Laid-Open Patent No. 2000-287189 system). [0003] Systems of the type described above typically examine attributes of content that are often selected by the user (eg, one of such attributes is the genre of the content) and suggest content based on each attribute deemed to match the user's preferences. [0004] However, the properties of content are typically estab...
