Description

Control method for recorded content in digital broadcasting program service {Method for controlling recorded contents for digital broadcasting program service}

The present invention relates to a method for controlling content recorded in a digital broadcast program service, and more particularly, a reservation recording list request function and a recorded content list request function in a digital broadcast program service such as TV-Anytime. In addition, the recorded content request function and the recorded content deletion request function are added to allow the user to effectively manage content recorded on a personal digital network recorder (NDR). It relates to a control method for the content.

The present invention is derived from the research conducted as part of the IT new growth engine core technology development project of the Ministry of Information and Communication and the Ministry of Information and Communication Research and Development. [Task Management Number: 2005-S-403-02, Title: Intelligent Integrated Information Broadcasting TV) technology development].

Recently, as digital broadcasting services are provided in earnest, researches on technologies for providing customized broadcasting services in a multi-channel multimedia environment have been actively conducted. For example, the 'TV-Anytime' forum defines and provides a standard of metadata structure so that all users can watch various types of programs at any time and in any way they want based on personal mass storage device (NDR). have.

The TV-Anytime Forum is a private standards body established in September 1999 with the aim of developing standards for providing audio-visual services in a user environment with a personal digital storage device (NDR).

Metadata refers to descriptive data about content, such as program titles, genres, and outlines, and is generally defined as data about data. In other words, the TV-Anytime metadata includes program description metadata and user description metadata. Program description metadata is composed of content description metadata and instance description metadata. Metadata for one program is correlated with a content identifier called a Content Reference Identifier (CRID). Content description metadata is generated by a content creator and includes program titles, genres, summaries, critic reviews, and the like. The instance description metadata is generated by a content provider and includes a location (broadcast time, channel, etc.), a usage rule, a delivery parameter, and the like. Finally, user description metadata includes user preferences, usage history, personal bookmarks, and the like, and is generated by the user.

The 9th standard of TV-Anytime, Remote Programming-ETSI TS 102 822-9 v1.1.1., Provides a data model and data transmission / reception method for the control of a personalized digital recorder (NDR). It is defined. The control_NDR operation, which is a representative remote procedure for this, provides three functions: a record request, a related status request, and a record cancel.

However, in the case of providing the NDR service using the reservation request function, the reservation status check function, and the reservation cancellation function, the above three functions are used for individual reservations for desired content, status check for individual reservation requests, and cancellation of individual reservations. Since only functions are provided, only processing functions for one reserved recording item are provided. That is, when the service is provided only by the reservation request function, the reservation status check function, and the reservation cancellation function, the user terminal additionally needs to store and manage information related to the reservation recording, as well as to a personal mass storage device (NDR). It is difficult to maintain and manage the storage space because there is no method of checking, viewing, and deleting the recorded content.

This is the information about all reservation recording items that the user registered by the member ID (SubscriptionId) has applied for (for example, the registration number of the reservation recordings that have been previously applied, and information about the program that was the subject of the reservation recording at the time of each reservation recording application). ), You'll need to store and manage your own content, as well as request content lists for content you've recorded for yourself that you haven't watched or kept for rewatching, and the physical location of the content you've selected for viewing in your recorded content list. There is a problem in that it is impossible to check and manage (delete) information about a recorded program due to the absence of a confirmation request and a deletion request function of content in which viewing is completed.

Accordingly, the present invention has been proposed to solve the above problems of the prior art, to manage the content stored in the personal mass storage device in a digital broadcast program service such as TV-Anytime, reservation recording list request function, By adding the function of requesting recorded content list, requesting recorded content, and requesting to delete recorded content, the user can effectively manage the recorded content on a personalized networked digital recorder (NDR). An object of the present invention is to provide a method of controlling content recorded in a digital broadcasting program service.

In the present invention, the following four functions are added to the control_NDR operation in order to effectively manage the reserved recording content in the personal mass storage device (NDR).

First, information about all the pre-booked recorded content lists (items) registered by a member ID (SubscriptionId), for example, a registration number (member ID) of a reservation recording request, and a reservation recording for each reservation recording request. A scheduled recording list request (RecordListRequest) function is added to request information about a program that was a target of the program.

The RecordListRequest function allows the user not only to view information on all reservation recording lists (items) that he / she has applied for at a time, but also allows recording of content in which reservation recording is meaningful at this time. It also helps to screen recording programs. For example, any user who wants to reserve an episode of a series needs to check how many episodes of the series they watched or reserved, and can check it from the reserved recording list.

Second, the RecordedContentListRequest function is added to check the list of contents that have been recorded and stored and managed in a personal mass storage device (NDR) but have not been watched or deleted for re-watching. .

Third, a Recorded ContentRequest function for physical location resolution of content selected by the user for viewing in the recorded content list is added.

Fourth, a recorded content deletion request (RecordedContentDelete) function for deleting content selected by the user from the recorded content list is added.
