    Abstract: A method performed by an accessory 104, e.g. AM/FM or high definition (HDTV) receiver, connected to portable media device (PMD) 102, comprises: determining whether a received broadcast track will be tagged, generating a tag comprising track identifying information, instructing connected PMD to open a tag file in a store, and writing the tag to the file. Also independently claimed is a similar method simply instructing the PMD to save the tag, omitting the 'file open' step. Also, a method including receiving plural tracks, with metadata, tagging a currently playing track, and instructing the PMD to open a tag file for a tag record containing a metadata portion for the current track. In addition, an accessory for a PMD, including a tag extraction engine; a method wherein a handle for a tag file is returned from media device to accessory; a method including communicating a tag identification information portion via a media asset delivery service; and a media asset access method generating an entry in a list of media assets. Further methods acquire a media asset including affiliate identifier requests that identify a referral source from which a client device obtained a unique asset (track) associated identifier.

    Abstract: A method, system, and connector interface for authenticating an accessory . A method includes performing an authentication operation and allowing the accessory to access the media player during the authentication operation; if the authentication operation fails, the accessory is locked out from any fu rther access to the media player. The authentication operation can include, e.g., validating authentication information included in an authentication ce rtificate provided by the accessory and/or validating a digital signature pr ovided by the accessory. The media player and accessory may utilize a plural ity of commands in a variety of environments such as within a connector inte rface system environment to control access to the media player.
