A computer-implemented method of transforming an image file by an image file transformation apparatus, the method including providing an image file in a pixel-based format having a plurality of pixels, dividing the pixels into a plurality of patches, sampling the pixels to generate boundary conditions relating to each of the patches, deriving Fourier coefficients of a solution to a partial differential equation according to the boundary conditions, and outputting the Fourier coefficients for each of the patches as a transformed image file.

A remote storage digital video recorder (RS-DVR) system is disclosed. The RS-DVR system includes a network interface to communicate data between the RS-DVR system and a subscriber system via a network, a file system module coupled to the network interface, an ingest agent coupled to the file system module to receive encoded media segments that represent media content files encoded at a plurality of different bitrates; and a storage architecture coupled to the file system to store the encoded media segments, resulting in stored media segments. The RS-DVR carries out a number of functions and operations to service multiple subscribers and associated subscriber systems, such as various storage device management operations, file structure techniques, assignment of recorded media to subscribers, file system indexing, and supporting shared and per-subscriber content rights.

A method begins by a processing module of a dispersed storage network (DSN) obtaining an identifier (ID) piece of multiple ID pieces regarding a registry fragment of a distributed DSN registry. The method continues with the processing module performing a function on the ID piece to obtain a registry fragment alias, wherein performance of the function on the multiple ID pieces would produce multiple registry fragment aliases. The method continues with the processing module determining DSN addressing information for the registry fragment based on the registry fragment alias, wherein the DSN addressing information is determinable from any one of the multiple registry fragment aliases. The method continues with the processing module receiving a response regarding the registry fragment when a local copy of the registry fragment is not up-to-date.

Systems and methods are described herein for synchronizing media asset playback on multiple devices. A media guidance application may transmit a media asset for simultaneous display to a first device and a second device. During playback of the media asset, the media guidance application may receive indications of the amount of the media asset consumed by the first and second device. In response to determining that one device has fallen behind in playback, the media guidance application may pause playback on other devices. In response to determining that the devices have become synchronized in playback, the media guidance application may resume playback on all devices.

A system, method and computer-readable medium are presented for providing real-time content-based navigation of live video programming. The method aspect of the invention comprises receiving a live video program, generating an index to the received live video program by extracting images and/or text from the video program, recording the live video program, presenting at least a portion of data associated with the generated index to a user, receiving user input regarding a portion of the recorded video program to which the user desires to navigate and playing back the recorded video program starting at the navigated portion identified by the user input.

A method includes receiving, at a media server, a request to create a media content summary. The request includes a user-specified criterion. The method includes identifying segments of media content based on annotation data. The annotation data includes annotations associated with a first segment of the segments and a second segment of the segments. The first segment is identified based on a number of corresponding annotations. The method further includes generating the media content summary by automatically changing a first size of the first segment and a second size of the second segment such that a total size of the media content summary satisfies the user-specified criterion.

A method includes receiving a media request for a target device. The signaling information may be received from the target device and a media server. At least one attribute of the target device and the media server may be identified using the signaling information. At least one attribute of the target device and the media server may be evaluated against a service level objective to select a media format. The service level objective may include consideration of the target device and available bandwidth over a provider network. The media may be provided in the selected media format over the provider network to the target device.

A broadcast targeting system is provided where third party database information is utilized in conjunction with broadcast network client information to identify households within the broadcast network including one or more desired recipients of targeted assets. In instances where a user equipment device of the targeted household includes multiple users (i.e., a multiple-user device), use of third party data in conjunction with an indication of which household member is currently using the multiple user device (e.g., set top box, etc.) allows for more effectively delivering assets targeted to a specific member(s) of the household.

A method and an apparatus are used to target interactive virtual objects to subscribers in a television delivery system. Programs are selected and virtual object locations are defined in the selected programs. The virtual objects available for targeting are categorized and the categories are correlated to subscriber information to determine the optimum targeting of the virtual objects. The virtual objects may be targeted based on individual subscriber information or on information related to groups of subscribers. When a frame of a program includes a virtual object location, a default or an alternate virtual object is displayed. The virtual object location may change over space or time. The virtual object may be interactive, and may be used to link a subscriber to a remote location, such as an Internet web site. An operations center or a cable headend may generate a group assignment plan that assigns the subscribers' television terminals to groups, based on factors such as area of dominant influence and household income. A retrieval plan is then generated that instructs the television terminals to select the desired virtual object for display. The television terminals record which virtual objects were displayed, and report this information to the cable headends and the operations center. The reported information is used to generate billing for commercial advertisers, and to analyze viewer watching habits. Interactive virtual objects are received by the television terminal with directions on actions to be taken upon selection of the interactive virtual object. Actions may result in the initiation of processes locally at the television terminal, or communication with a remote site for the initiation of processes to be performed remotely. The invention uses upstream data reception hardware, databases and processing hardware and software, and corresponding features in the televisions to accomplish these functions.

A system and method are provided of minimizing network bandwidth used from an external network by client peers in a local network. The method can include the operation of organizing a plurality of clients each having media streamlets and a client parent in a structure within the local network. Mapping information propagates through the structure. The mapping information represents local streamlet locations as stored by the plurality of clients. Another operation is retrieving a local streamlet from a client identified in the mapping information as having the local streamlet for the requesting client.
