A system and method for transferring Very Large Files (VLFs) from a content provider to a requesting node over a network via a proxy are provided. The content provider processes a VLF to provide a chunked VLF. The chunked VLF includes a number of chunks each including a portion of the VLF. A transfer is initiated when a request for the VLF is sent from the requesting node to the proxy. The proxy then determines if any of the chunks of the chunked VLF are stored in proxy cache associated with the proxy. If not, the proxy directs the request to the content provider. In response, the content provider sends the chunks of the chunked VLF to the proxy. Upon receiving each of the chunks, the proxy stores the chunk in the proxy cache and sends the chunk to the requesting node.

A system and method are provided for synchronizing playback of media content on multiple playback devices utilizing Digital Rights Management (DRM) encoding. In general, multiple playback devices or users of those playback devices are associated to form a virtual group. A virtual group (VG) control function operates to synchronize advertisement (ad) slots within media content provided to the playback devices in the virtual group utilizing DRM encoding.

The present invention provides a system and method for recommending operational information, such as play lists or settings, for one or more devices associated with a local wireless network based on content information describing content stored on a number of user devices within the local wireless network. More specifically, a recommendation engine obtains the content information for a number of user devices within the local wireless network from either a central node or the user devices and analyzes the content information to recommend operational information for one or more devices associated with the local wireless network.

A system and method are provided for utilizing a secondary device to overlay disassociated media elements onto video content presented to a user via a primary device. In general, an overlay control function of a secondary device provides an overlay input to a primary device playing video content. The overlay input includes one or more media elements forming the overlay as well as information defining a desired position of the overlay. In response, an overlay rights enforcement function of the primary device obtains overlay access rights and determines whether the overlay is permitted based on overlay access rights. If the overlay is permitted, the overlay formed by the one or more media elements provided in the overlay input received from the secondary device is overlaid on top of the video content being played by the primary device.

A system and method for automatically configuring a content capture device according to a configuration profile for a desired service are provided. In general, the user of the content capture device registers for one or more services. Thereafter, in one embodiment, the user of the content capture device selects one of a desired service prior to content capture. In another embodiment, the desired service is selected based on contextual information obtained by the content capture device. Once the desired service is selected, the content capture device obtains a configuration profile for the desired service. The configuration profile includes required or suggested configurations for the content capture device when capturing content to be distributed to the desired service. The content capture device performs an auto-configuration process based on the configuration profile. Once the content capture device is configured, content captured by the content capture device is distributed to the desired service.

The present invention provides a system and method for modifying a profile of a user device prior to sending the profile to a destination server, wherein the destination server customizes content provided to the user device based on the modified profile. In general, the profile of the user device may include information identifying capabilities of the user device, user preferences, and demographic information regarding a user of the user device. At either the user device or a mediating server interconnecting the user device and the destination server, the profile of the user device is modified based upon one or more rules to provide the modified profile. The modified profile is then provided to the destination server, which customizes content provided to the user device based on the modified profile.

A system and method are provided for creating collaborative content tracks to be presented to a user concurrently with a media presentation such as a movie, an episode of a television series, a song, or the like. Each time a user selects and plays a media presentation, user events describing actions taken by the user while viewing or listening to the media presentation are collected and provided to a Collaborative Content Track (CCT) server. The user events may include user events occurring on a primary media playback system, user events occurring on associated secondary user devices, or a combination thereof. In this manner, the CCT server obtains user events for each of a number of media presentations. Based on the user events, the CCT server may generate CCTs for any one of the media presentations to be presented to a user concurrently with the media presentation.

A system and method are provided for identifying participants for a preferential ad-hoc network using a peer-to-peer (P2P) network and then establishing the ad-hoc network with the identified participants. In general, an initiating peer node provides a request for participants for an ad-hoc network to the P2P network, wherein the request includes content information describing content stored at the initiating peer node. The content information is used by the peer nodes receiving the request to determine whether to join the ad-hock network. The peer nodes receiving the request that decide to join the ad-hoc network respond to the initiating peer node via the P2P network. All or select ones of the peer nodes responding to the request are identified as the participants for the ad-hoc network. Once the participants are identified, the initiating peer node dynamically establishes the ad-hoc network with the identified participants.
摘要:
A method and apparatus for redirecting client-side storage operations to one or more remote storage devices. An HTTP message generated by a web server includes one or more client-side storage operations. Based on defined criteria, the client-side storage operations are replaced with remote storage instructions to generate a modified HTTP message. The modified HTTP message is sent towards the client device. A user agent on the client device receives the HTTP message and executes the remote storage instructions. The storage operations are implemented on the remote storage devices rather than on the client.

A system and method are provided for accessing and managing information, or metadata, describing content residing on a number of agent devices. In general, the system includes a central node and a number of agent devices communicatively coupled by a network. In operation, the central node communicates with the agent devices to obtain content information describing content stored at the agent devices and optionally the locations of the agent devices from the agent devices. The content information and optionally the locations of the agent devices are stored in a database associated with the central node. Thereafter, the central node enables requesting nodes such as the agent devices to access the database. In addition or alternatively, the central node may provide automatic alerts to the agent devices when other agent devices matching specified criteria are available.
