Excerpt
Excerpt
Abstract: A DVR, server, or other agent correlates media metadata from diverse sources, like an EPG data provider and multiple video-on-demand (VOD) service providers. Metadata sets from different sources are compared in order to attempt to identify identical programs to which the metadata sets pertain. From at least one metadata set, information about the program that the other metadata set lacks is selected. A “canonical” data structure instance for the program is created. The information that is lacking from at least one of the metadata sources is inserted into that instance. For each source from which a program is available, the DVR stores the identity of that source on the DVR's persistent storage device in association with the canonical data structure instance for that program. The DVR receives search criteria from a user and then searches the stored canonical data structure instance for programs that satisfy the criteria.
[0005]Some DVRs allow a DVR user to search for specific programs in which the DVR user might be interested. For example, in response to a DVR user's search request, a DVR might present, to the DVR user, a user interface into which the DVR user can enter criteria that programs in which the DVR user is interested ought to satisfy. The user interface might contain different user-fillable fields for different types of criteria that programs could satisfy. For example, a user interface might contain a “title” field, one or more “actors” fields, a “category” and/or “genre” field, a “year” field, a “rating” field, etc. After receiving the user-specified criteria through such a user interface, the DVR searches program metadata that the DVR obtained from the EPG data provider. Typically, the EPG-provided program metadata will indicate, for each program, the kinds of information (e.g., title, actors, category, genre, year, rating, etc.) for which the user entered criteria. The DVR determines, based on the EPG-provided program metadata, a set of to-be-broadcasted programs that are associated with program metadata that satisfies the user-specified criteria. The DVR then presents, to the DVR user, a list of to-be-broadcasted programs that are contained in the set.
