Disclosed are various embodiments directed to transcoding a bit stream comprising audio and video frames that contains discontinuities. The video and/or audio portion of the bit stream may be divided into segments, where some of the segments are transcoded in parallel using a plurality of transcoder devices. In some embodiments, a discontinuity is detected in the bit stream before encoding, where the discontinuity is associated with a shift in a set of time stamps associated with the bit stream. A magnitude of the discontinuity is determined. The transcoding system aligns at least a portion of the audio frames to the series of video frames according to at least the discontinuity and the magnitude of the discontinuity. In other embodiments, the discontinuity is detected after encoding by analyzing time stamps that have been established during the transcoding process.

A system and method for optimizing a compound prediction setting for a media stream and signaling the compound prediction setting is disclosed. A rate distortion optimization using the prediction modes of a compound prediction setting is carried out, and the rate distortion result is extrapolated to different compound prediction settings, without having to process each compound prediction setting separately. The optimal compound prediction setting is selected, and an element is encoded into the bitstream indicating the compound prediction setting that is used. A gradual mode coding scheme is used to minimize the bandwidth cost, and preserve the bandwidth savings of the compound prediction mode.

Systems and methods are described for automatically driving portions of a video production workflow according specifications governed by a data-rich storyboard. Embodiments operate in context of a novel video production workflow in which much or all of the production expertise of a traditional production workflow collaborates at a storyboard phase of the workflow to architect a single, data-rich storyboard according to concepts and rules. The rich storyboard is generated and stored in a data framework that drives specifications over the workflow in such a way that portions of the workflow can be automated and consistently repeated. For example, the rich storyboard drives generation of automated coaches for acquisition and pre-auditing of individualized story assets from storymakers. The rich storyboard can then drive automated rendering of the assets into multiple, individualized storyvine video products that each conforms to the rich storyboard concepts, rules, and specifications.

Disclosed is an information processing method comprising the steps of: storing measured position information in association with first time information representing times of day at which the measured position information is obtained; storing video information in association with second time information representing times of day at which the video information is obtained; and associating the measured position information with the video information in accordance with degrees of difference between the first time information and the second time information.

A recording apparatus is disclosed that records information data and file system information for managing a file containing the information data in accordance with a predetermined file system to a recording medium having a plurality of blocks including an alternative block for a detect block. The data recorded in the recording medium is managed in accordance with the predetermined file system. The recording apparatus sets a threshold based on the size of the file system information, and if the alternative block remaining amount in the recording medium is less than or equal to the threshold, recording of the information data to the recording medium is inhibited.

A correlation-based system for watermarking continuous digital media at the system application level. It is a post-compression process for watermarking where no a priori knowledge of the underlying compression algorithm is required. Per each compressed media frame, a current unique digital signature is generated based on the data from the current compressed frame plus the digital signature that has been previously generated. The signature thus generated is then used in conjunction with the next compressed frame to generate the next unique digital signature. All digital signatures are correlated according to the above process until a “reset” signal is issued. A new chain of correlated digital signatures is produced by the system with a pre-determined initial signature.

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.

According to one embodiment, there is provided a control block including a read control processor for reading designated content, a time information processor for processing time information. A controller returns, to a user terminal, a response signal, and information indicating a second absolute time point when an operation is executed in response to a request signal generated by the user terminal at a first absolute time point. The controller stores time difference information indicating a time difference between the first and the second absolute time points. When responding to a further request signal sent from the requester via the network, the controller sets, as tag time information, time information obtained by correcting, using the time difference information, a current relative time period for which the designated content is read.
