Electronic program guide with tagging

A computer program product, tangibly embodied in a machine-readable storage device, the computer program product including instructions being operable to cause data processing apparatus to:

• store, on a computer-readable storage device, an active media object list identifying media objects in an active state, the media objects in an active state being defined by those media objects currently accessible by a user via one or more broadcast channels, one or more local media object storage devices, one or more remote media object storage devices, or any combination thereof;
• receive one or more tag requests identifying one or more programs, each of the one or more programs being associated with one or more media objects;
• update a tag list stored on the computer-readable storage device to identify the one or more programs identified by the one or more tag requests;
• receive a guide information request for tagged media objects that are in an active state;
• generate a user navigation list comprising source identifiers of a plurality of selected media objects and a plurality of titles associated with each of the plurality of selected media objects, the plurality of selected media objects each being associated with at least one of the one or more programs identified in the tag list and being included in the active media object list;
• and
• transmit the user navigation list to a display device for displaying one or more pairs of the plurality of source identifiers and titles.

A data processing apparatus for providing an electronic program guide, the data processing apparatus comprising:

• means for storing, on a computer-readable storage device, an active media object list identifying media objects in an active state, the media objects in an active state being defined by those media objects currently accessible by a user via one or more broadcast channels, one or more local media object storage devices, one or more remote media object storage devices, or any combination thereof;
• means for receiving one or more tag requests identifying one or more programs, each of the one or more programs being associated with one or more media objects;
• means for updating a tag list stored on the computer-readable storage device to identify the one or more programs identified by the one or more tag requests;
• means for receiving a guide information request for tagged media objects that are in an active state;
• means for generating a user navigation list comprising source identifiers of a plurality of selected media objects and a plurality of titles associated with each of the plurality of selected media objects, the plurality of selected media objects each being associated with at least one of the one or more programs identified in the tag list and being included in the active media object list;
• and
• means for transmitting the user navigation list to a display device for displaying one or more pairs of the plurality of source identifiers and titles.
