Abstract: An arrangement for packaging and transferring files such as content items and metadata in synchronization operations. Files are packaged in a concatenated fashion in order to optimize usage of the transfer channel, while maintaining an ability to keep track of how many files have been transferred. Metadata associated with the files may be sent in a single package in advance of sending the files. The metadata may be compressed using both a custom mechanism that takes into account predictable commonalities inherent in metadata for multimedia files, as well as standard compression techniques.

Abstract: Each of one or more songs in a song list is analyzed to determine whether the song satisfies a set of criteria at its current location. For each of the one or more songs that satisfies the set of criteria, the song is kept at its current location in the song list. For each of the one or more songs that does not satisfy the set of criteria, an attempt is made to select (e.g., randomly) another song in an unprocessed portion of the song list that satisfies the set of criteria. If a selected song satisfies the set of criteria then the song and the selected song are swapped. However, if greater than a threshold number of attempts to select a song that satisfies the set of criteria are made, then the song is kept at its current location in the song list.

Abstract: A system that facilitates implementation of business rules for multimedia content on a portable device comprises a receiver component that receives a request for support of extensions to a protocol that enable transfer of customized business rules associated with multimedia content from a host device to a portable device, the portable device is a closed system. A servicing component provides the requested support to an entity that initiated the request.

Abstract: Arrangements and techniques for enumerating portable device contents via a content management device are discussed herein. The portable device is caused to create and store a first data structure, referred to herein as a portable database, corresponding to the contents of a media library stored thereon. Upon connection to a content management device, the portable database is copied to the content management device, and is used in conjunction with information stored by the content management device in a second data structure, referred to herein as a device content table, to efficiently enumerate and provide other manipulation of the contents of the media library stored on the portable device.
