Abstract

Described herein are systems and methods for managing different formats for media files and playback devices in a media system. The media system may include a source device, at least one playback device, and a manager device coupled through a communication system. The source device may store a plurality of media files for various media forms (e.g., video, audio, image, or gaming media files). Each media file and playback device may have a playback format that is specified by values of one or more format parameters. The manager device may automatically determine format parameters of each media file and playback device and store to a media data structure. The manager device may also automatically determine and store compatibility data indicating format compatibility between different media files and playback devices, the compatibility data being used to automatically convert media files to the formats of the playback devices.

12. A method for managing playback formats of a media system comprising at least one source device, at least one playback device, and a manager device coupled with the at least one source device and the at least one playback device, the at least one source device configured for storing a plurality of media files, each media file having a format defined by at least one format parameter value, and the at least one playback device configured for playing media files in a format defined by at least one format parameter value, the method comprising:

using the manager device, producing a media data structure comprising a plurality of media file entries for the plurality of media files, each media file entry representing a media file;

using the manager device, for each media file in the plurality of media files, determining compatibility data indicating compatibility of the format of the media file with the format of each playback device, and storing the compatibility data to the media file entry for the media file in the media data structure; and

using the manager device, for at least one media file, using the compatibility data in the media file entry for the media file to convert the media file to a format of at least one playback device.

13. The method of claim 12, wherein a format of a playback device comprises zero or more required format parameter values and zero or more preferred format parameter values.
