Abstract: One embodiment sets forth a technique that includes receiving a request for a range of data included in an encoded version of the media title that is stored across a set of files. The technique also includes determining, based on a file extent index, one or more files included in the set of files, wherein the file extent index maps an identifier for each file in the set to a given range of data that is stored in the file and included in the encoded version. The technique further includes retrieving the range of data from the file(s), wherein at least a portion of the retrieved range of data falls within the given range of data that is stored in each of the one or more files, and transmitting the range of data in a response to the request.

Abstract: Systems, devices and processes reduce the amount of memory or disk space needed to store encoded video content used in adaptive video streaming by eliminating certain portions of the recorded program from one or more copies of the encoded program. Content occurring before or after a scheduled start of a program, for example, can be retained in only a subset of the encoded copies so that the program content is available to be streamed, but only at certain video qualities. Commercials or other less popular portions may also be eliminated in one or more encoded copies. By eliminating the less-likely-to-be-viewed portions of the content from some (but not all) of the encoded copies, the total amount of storage space needed to store the encoded program is reduced without compromising the ability to play back all portions of the recorded program.

Abstract: Aspects of the present disclosure provide for systems and methods that provide automatic failure options from a primary recording and/or playback device/system to a backup recording and/or playback system, but are not so limited. A disclosed system operates to failover to one or more of a backup cDVR system and/or local DVR device/system when a primary recording and/or playback device/system is inoperable or otherwise inaccessible. A method of an embodiment operates to automatically failover to a backup DVR device/system upon detecting a failure mode associated with a primary DVR device/system, wherein the automatic failover includes synchronizing one or more content items and/or one or more content items playlists associated with the backup DVR device/system and the primary DVR device/system.

Abstract: A computer-implemented method is described for automatically digitally transforming and editing video files to produce a finished video presentation. The method includes the steps of storing video files with associated tags, recording or receiving from a user a master video, matching the words or phrases recorded in the master video with the tags to determine one or more locations at which to insert the video files, and automatically assembling the master video and video files into the finished video presentation. Audio and visual effects may also be added to the video presentation. Computer apparatus configured to generate the video presentation is also described.

Abstract: Systems and methods for providing an interactive media guidance application for merging recorded video segments that are from the same program are provided. In response to a recording interruption, the interactive media guidance application may record multiple video segments. After recording the segments, the interactive media guidance application may search for and merge these segments to form a single recording. In some embodiments, the interactive media guidance application may detect the presence of a previously recorded segment. After detecting the previously recorded segment, the interactive media guidance application may automatically record the video following the end of the previously recorded segment. The interactive media guidance application may use data associated with the segments and other media cues to match the segments. The interactive media guidance application may also identify the duration of the recorded video content and provide choices for recording the video again.

Abstract: A method, and corresponding computer program product and computer system, for replicating a database image in a distributed database environment comprises: defining a checkpoint image of the primary node including a database structure and a plurality of database pages; creating a replica database by initiating a backup node and saving the defined structure on the initiated backup node; sending each database page of the checkpoint image for saving on the backup node; saving every transaction on the primary node and creating a corresponding REDO transaction; identifying each data page operated on by each REDO transaction; sending each created REDO transaction to the backup node in the order in which the corresponding transaction occurred, and prioritizing each identified database page so that it arrives at the backup node before or substantially at the same time as a corresponding REDO transaction.

Abstract: A digital display device and a method for controlling the same are disclosed. The method of controlling a digital display device connected to at least one network and at least one memory includes receiving content (e.g., a TV program, etc.) over the at least one network, calculating memory capacity of an internal or external memory, storing the received content (e.g., a TV program, etc.) in the internal or external memory according to the calculated result, accessing the internal or external memory if a specific channel is selected, extracting the content (e.g., a TV program, etc.) stored in the accessed internal or external memory, and outputting video data and audio data corresponding to the extracted content (e.g., a TV program, etc.).

Abstract: A content can be recorded for certain in a video recording system including a video recording apparatus and a video recording and transmitting apparatus. The video recording apparatus includes: a recording control unit that starts recording the content when a period of time indicated by scheduled recording information starts; and a message transmitting unit that transmits recording-state information to the video recording and transmitting apparatus at regular intervals. The video recording and transmitting apparatus includes: a recording-state monitoring unit that determines whether or not the continued reception of a signal has been suspended during the period of time; and a recording control unit that starts recording the content when the recording-state monitoring unit determines that the continued reception of the signal has been suspended.

Abstract: Recording reconstruction from multiple overlapping recordings may be provided. New recorders may copy manifests from working recorders, as opposed to reconstructing from failed recorders, to construct manifests that refer to video fragments from different recorders. Origin servers may follow these reconstructed manifests to obtain any fragment in the recording, in any combination of recorder failure/take-over/restart, as long as there was at least one recorder functioning at all times.

Abstract: Provided is a metadata structure for storing and re-producing stereoscopic data and a method for storing a stereoscopic content file based on the metadata structure. The stereoscopic content file storing method includes storing streams of the stereoscopic contents; and, when the stereoscopic content has more than two elementary streams, storing information for dividing the elementary streams into a main track and a supplementary track.

Abstract: A video decoding device includes a decoder configured to decode a plurality of separate partial areas of each of pictures included in encoded video data and a motion vector indicating a positional relationship between each of the partial areas and a partial area of a different picture referenced in order to encode the partial area; an error detector configured to detect, as an error area, a partial area that is unable to be decoded by the decoder from among the plurality of partial areas; a referenced area determiner configured to determine a referenced area of a third picture that has already been decoded, the referenced area corresponding to the error area; a concealment unit configured to conceal the error area using data included in the referenced area; and an image integrator configured to reproduce the first picture.
