Algorithms and methods for video transcoding.
Video transcoding is the process of dynamic video adaptation. Dynamic video adaptation can be defined as the process of converting video from one format to another, changing the bit rate, frame rate or resolution of the encoded video, which is mainly necessitated by the end user requirements. H.264 …

Rate control and bit allocations for JPEG transcoding
… saving more bits as needed throughout the transcoding of the image. This intra-image process decrements specific coefficients, minimizing the change in value (and hence image quality) while maximizing the savings in bitrate. The result is a fast JPEG transcoder that reliably achieves a …

Transcoding multilingual and non-standard web content to voiceXML
Transcoding systems redesign and reformat already existing web interfaces into other formats so that they can be available to other audiences. For example, change it into audio, sign language or other medium. The bene_t of such systems is less work on meeting the needs of di_erent audiences. This …

Anti-Freeze: High-Quality Adaptive Live Streaming with Real-time Transcoder
… pose a challenge for real-time video transcoding and streaming. Transcoding is a computationally intense process and if not performed efficiently it can result in unwanted delays, which further limit the Quality-of-Service (QoS) delivered by the streaming protocol. In this thesis, we …

Robust Content Identification and De-Duplication with Scalable Fisher Vector In video with Temporal Sampling
… that is agnostic to the typical coding and transcoding variations. The key innovations are a key point repeatability model that selects the best key point features, and a non-uniform sampling scheme that significantly reduces the bits required to represent a segment, and scalability from PCA …

Out-of-core image techniques with extensions for WAMI
… format, and a novel fast method for online transcoding of data to this out-of-core format. Specific extensions are provided for Wide Area Motion Imagery (WAMI) with spatio-temporal caching and distributed rendering for large tiled displays. A brief study is also made for extending these …

Aesthetic forms of expression as information delivery units
… techniques, which require a conscious act of transcoding, these aesthetic forms stimulate more direct, emotional response. Such a hypothesis could open a new channel for the delivery of various types of information, providing us, in situations of information overload, with a background …

A real-time audio transcoder with watermark images for content protection and quality of service monitoring
… present a universal media access-compliant (UMA) transcoding module along with a watermarking-based data-hiding module that provides copyright protection as well as data integrity, authenticity assurance, and QoS monitoring. The audio was first adapted to multiple clients' needs on the server …

English productions of 'Measure for Measure' on stage and screen : the play's indeterminacy and the authority of performance
… in adapting the text of Measure for Measure or transcoding it into a different, two-dimensional media of the screen, the adaptor sets himself up as a rival authority to that of Shakespeare and, in consequence, changes our perception of the ‘work’. The adaptations of Measure for Measure from the …
