A client-side FEC selection system involves pre-generating FEC data for a plurality of media segment streams based on a number of FEC configuration settings at a server. Metadata relative to the FEC data may be provided to a client device via appropriate manifest files or other mechanisms, whereupon the client device is operative to select and request a suitable FEC data fragment responsive to monitoring various network characteristics.

Dynamic client-side selection of FEC information

A method of synchronizing playback of a media asset between a first playback device and one or more other playback devices includes synchronizing an initial playback timeline of a media asset with a reference clock, and then playing the media asset with the initial playback timeline on each of the two or more playback devices. In response to a playback-alteration command, an updated playback timeline of the media asset is synchronized with the reference clock, and the media asset is then played with the updated playback timeline on each of the two or more playback devices.

In a computing device, both an address of a first device and a secret are graphically encoded to generate one or more images that can be captured by a second device. The second device captures and decodes the one or more images, and sends a communication initiation request to the address of the first device. The communication initiation request includes the address of the second device and identifies the secret. Communication between the first and second device continues only if the first device verifies, based on the communication initiation request, that the second device knows the secret.

Device pairing based on graphically encoded data

User-specific attribute customization is provided by an entertainment system including a user identification module to identify one or more users within an operative range of the entertainment system, and a dominant attribute module to automatically express exclusive user-specific attributes of a dominant user when the dominant user is one of two or more identified users within the operative range of the entertainment system. The entertainment system further includes a cooperative attribute module to automatically express merged user-specific attributes of a first user and a second user when the first user and the second user are two of two or more identified users within the operative range of the entertainment system.

User-specific attribute customization

A first software program executing on a computing device emulates a second computing device executing a software program using emulated memory. The first software program permits the second software program to perform an operation on a contiguous portion of the emulated memory only when a pointer and a table entry both contain the same identifier, thus protecting against common types of memory usage errors in the second software program. The pointer has an address to the contiguous portion. The table entry maps to the contiguous portion. A plurality of table entries map to a respective plurality of contiguous portion of the emulated memory. A plurality of the pointers each contain the address to a respective contiguous portion of the emulated memory as well as containing an identifier corresponding to the respective contiguous portion of the emulated memory. The second computing device can be high or low in resources.

The invention involves transmission download of data to plural, mass storage medium-based remote users of content or software upgrades or multiple versions. Optionally provided are pre-download scheduling of one or more future download sessions and post-download remote scripted software execution by the remote clients. For purposes of more efficient use of the transmission link, low-volume scheduling information or content are transmitted within designated narrow-bandwidth sub-channels or trickle streams allocated within the broad bandwidth of the transmission channel and such allocation may be dynamic to vary the allocation based upon relative high-volume, high-speed and low-volume, low-speed demands. The invention is implemented in software residing primarily in the server computer connected with the transmission provider. The software schedules allotted bandwidth within the broadcast band of the transmission link and formats high-volume data for transmission within sub-allocation channels logically devised therein. Client software at the plural distributed home entertainment device sites reserves capacity on disk and receives such transmission data for storage thereon, optionally executing a downloaded execution script that may reconfigure the client software so that new options and features are available at the client site for operational enhancements as well as video program or content enhancements. Client software at the plural distributed home entertainment device sites reserves capacity on disk and receives such broadcast data for storage thereon, optionally executing a downloaded execution script that may reconfigure the client software.

The invention involves storing data on a storage medium without fragmentation. A data conveyance system configures data for delivery to a data storage system and associates a storage instruction with the data. The storage instruction instructs the data storage system to store the data without fragmentation. The data conveyance system then conveys the data and the storage instruction to the data storage system. The data storage system receives the conveyance and a controller reads the storage instruction. The controller stores the data in contiguous storage locations on the storage medium in accordance with the storage instruction. If the storage medium is a disk, the data conveyance system may configure the data for delivery to the data storage system by generating a filesystem and combining the data and the filesystem to form a partition file. The data conveyance system then associates the storage instruction with the partition file and conveys the storage instruction and partition file to the data storage system. The data storage system controller formats the storage disk to include a new disk partition and stores the partition file in the new disk partition. Alternatively, the controller may first read the data storage disk to find contiguous storage locations which are empty, and store the partition file only if sufficient available storage locations are found. As a further alternative, the controller may first de-fragment the storage disk to increase the number of contiguous storage locations available for storage.
