Scalable video coding (svc) file format
TLDR
In this paper, extensions to the AVC file format are made to provide a new SVC file format that enables the storage and access of scalable video data, which is stored as a single track within a media data section of the SVC format.Abstract:
The currently existing ISO/AVC file format is modified by providing extensions to store and access video content currently being defined by the SVC standard. Specifically, extensions to the AVC file format are made to provide a new SVC file format that enables the storage and access of scalable video data. The scalable video data is stored as a single track within a media data section of the SVC file format. New extensions are defined for description entries and boxes within a metadata section of the SVC file format. These extensions provide means for extracting sub-streams or layers from the single track of scalable video data stored in the media data section.read more

Image processing device and method
TL;DR: In this paper, an image processing device and a method that make it possible to suppress block noise is presented, which can be applied to an image processor and can be used to suppress noise in a filter process determination unit.
Patent
Information additive code generator and decoder for communication systems
TL;DR: In this article, an encoder uses an input file of data and a key to produce an output symbol with key I. The output symbols are generally independent of each other, and an unbounded number (subject to the resolution of I) can be generated, if needed.
Patent
Enhanced block-request streaming using scalable encoding
TL;DR: Block as discussed by the authors is a block request streaming system, where the files or data elements are organized as blocks that are transmitted and decoded as a unit, and the system is configured to provide and consume scalable blocks such that the quality of the presentation increases as more of the block is downloaded.
Patent
Enhanced block-request streaming using cooperative parallel HTTP and forward error correction
TL;DR: A block-request streaming system provides for improvements in the user experience and bandwidth efficiency of such systems, typically using an ingestion system that generates data in a form to be served by a conventional file server (HTTP, FTP, or the like), wherein the ingestion system intakes content and prepares it as files or data elements to be serve by the file server, which might or might not include a cache as mentioned in this paper.

Patent
Metadata based file switch and switched file system
TL;DR: In this paper, the file switch (200) aggregates the file server's responses to the client computer's request and presents a single response back to the clients computer, in a manner that is transparent to both the clients and the file servers.
Patent
Method and apparatus for adaptive up-scaling for spatially scalable coding
TL;DR: Adaptive up-sample filtering is used to improve compression efficiency of spatially scalable coding systems by more effectively predicting the high-resolution (enhanced-layer) video from the low-resolution lower-layer video (or image).
