Method for secure storage and delivery of media content

The memory device contains control structures that allow media content to be stored securely and distributed in a manner envisioned by the content owner, or service providers involved in the distribution. A wide variety of different avenues become available for distributing media content using such memory devices, such as where the devices contain one or more of the following: abridged preview media content, encrypted unabridged media content, prepaid content, rights and / or rules governing access to such content. The memory device has a type of control structures that enable a service provider (who can also be the content owner) to create a secure environment for media content distribution where end users and terminals register with the service provider, and gain access to the content in a manner controlled by the service provider. The various components to be loaded (e.g. abridged preview media content, encrypted unabridged media content, prepaid content, rights and / or rules governing access to such content) may be generated and loaded in a secure and efficient manner.

Filesystem-Aware Block Storage System, Apparatus, and Method

A filesystem-aware storage system locates and analyzes host filesystem data structures in order to determine storage usage of the host filesystem. To this end, the storage system might locate an operating system partition, parse the operating system partion to locate its data structures, and parse the operating system data structures to locate the host filesystem data structures. The storage system manages data storage based on the storage usage of the host file system. The storage system can use the storage usage information to identify storage areas that are no longer being used by the host filesystem and reclaim those areas for additional data storage capacity. Also, the storage system can identify the types of data stored by the host filesystem and manage data storage based on the data types, such as selecting a storage layout and / or an encoding scheme for the data based on the data type.

Play list manager

A play list manager is disclosed that can be used to create and update play lists. The play lists can be used for audio information, visual information, or a combination of audio and visual information. The user of the play list manager creates a play list and specifies certain criteria for automatically adding tracks to the play list. When a new track is added to the environment, the system tests whether the track's properties satisfy the criteria for the play list. If so, the new track is automatically added to the play list. In one alternative, a user can select a predefined play list, whose criteria has already been created. Upon selection of the predefined play list, the play list manager accesses each track and adds the track to the play list if the track's properties satisfy the criteria for the predefined play list.

Network-based data collection, including local data attributes, enabling media management without requiring a network connection

Consistent user experience of playlist capabilities, despite differences in available resources and on-line connectivity, is provided. Data embedded in a playback device compensates for lack of connectivity. For compactness, embedded data can be targeted to geographic region(s) by selecting metadata for recordings containing audio using statistics on playback of the recordings in many geographic regions. The statistics and corresponding metadata are segregated by the geographic regions. Then a portion of the corresponding metadata is selected for at least one of the geographic regions based on the statistics. By using statistics that indicate popularity of recordings within geographic regions based on frequency of playback or requests for information about a recording when it is played, the portion of the corresponding metadata that is selected can be tailored for individual geographic regions. To ensure that subregions and genres are not totally excluded, the portion selected may not be solely based on popularity.

Method for exchanging logical volumes in a disk array storage device in response to statistical analyses and preliminary testing

Load balancing of activities on physical disk storage devices is accomplished by monitoring reading and writing operations to logical volumes on the physical disk storage devices. A list of exchangeable pairs of logical volumes is developed based on size and function. Statistics accumulated over an interval are then used to obtain access activity values for each logical volume and each physical disk drive. A statistical analysis selects one logical volume pair. After testing to determine any adverse effect of making that change, the exchange is made to more evenly distribute the loading on individual physical disk storage devices.
