In one embodiment, the one control server is also operable to calculate a utility of each caching option and enforce it by sending triggers to the peers to initiate the caching at those peers. | 02-26-2009 |

20130117270 | CATEGORY-PREFIXED DATA BATCHING OF CODED MEDIA DATA IN MULTIPLE CATEGORIES - Innovations for category-prefixed data batching (“CPDB”) of entropy-coded data or other payload data for coded media data, as well as innovations for corresponding recovery of the entropy-coded data (or other payload data) formatted with CPDB. The CPDB can be used in conjunction with coding/decoding for video content, image content, audio content or another type of content. For example, after receiving coded media data in multiple categories from encoding units, a formatting tool formats payload data with CPDB, generating a batch prefix for a batch of the CPDB-formatted payload data. The batch prefix includes a category identifier and a data quantity indicator. The formatting tool outputs the CPDB-formatted payload data to a bitstream. At the decoder side, a formatting tool receives the CPDB-formatted payload data in a bitstream, recovers the payload data from the CPDB-formatted payload data, and outputs the payload data (e.g., to decoding units). | 05-09-2013 |
20130155047 | IMAGE THREE-DIMENSIONAL (3D) MODELING - Among other things, one or more techniques and/or systems are disclosed for creating a three-dimensional model of an image. Image data, comprise a series of images of a location, such as along a route, can be received. The image data can comprise a first image element location for a first image element, where the first image element location may correspond to a three-dimensional point in the image, such as a location in the image with a depth from a point of observation. The first image element can be segmented into a first façade plane using the first image element location. The first façade plane can be merged with a second façade plane, resulting in a three-dimensional model of the image. The second façade plane can comprise a second image element, where the image data comprises a second image element location for the second image element. | 06-20-2013 |
20130272430 | CONSTRAINTS AND UNIT TYPES TO SIMPLIFY VIDEO RANDOM ACCESS - Disclosed herein are innovations for bitstreams having clean random access (CRA) pictures and/or other types of random access point (RAP) pictures. New type definitions and strategic constraints on types of RAP pictures can simplify mapping of units of elementary video stream data to a container format. Such innovations can help improve the ability for video coding systems to more flexibly perform adaptive video delivery, production editing, commercial insertion, and the like. | 10-17-2013 |

20140092991 | CONDITIONAL SIGNALLING OF REFERENCE PICTURE LIST MODIFICATION INFORMATION - Innovations in signaling of reference picture list (“RPL”) modification information. For example, a video encoder evaluates a condition that depends at least in part on a variable indicating a number of total reference pictures. Depending on the results of the evaluation, the encoder signals in a bitstream a flag that indicates whether an RPL is modified according to syntax elements explicitly signaled in the bitstream. A video decoder evaluates the condition and, depending on results of the evaluation, parses from a bitstream a flag that indicates whether an RPL is modified according to syntax elements explicitly signaled in the bitstream. The condition can be evaluated as part of processing for an RPL modification structure that includes the flag, or as part of processing for a slice header. The encoder and decoder can also evaluate other conditions that affect syntax elements for list entries of the RPL modification information. | 04-03-2014 |
20140092998 | FRAME PACKING AND UNPACKING HIGHER-RESOLUTION CHROMA SAMPLING FORMATS - Video frames of a higher-resolution chroma sampling format such as YUV 4:4:4 are packed into video frames of a lower-resolution chroma sampling format such as YUV 4:2:0 for purposes of video encoding. For example, sample values for a frame in YUV 4:4:4 format are packed into two frames in YUV 4:2:0 format. After decoding, the video frames of the lower-resolution chroma sampling format can be unpacked to reconstruct the video frames of the higher-resolution chroma sampling format. In this way, available encoders and decoders operating at the lower-resolution chroma sampling format can be used, while still retaining higher resolution chroma information. In example implementations, frames in YUV 4:4:4 format are packed into frames in YUV 4:2:0 format such that geometric correspondence is maintained between Y, U and V components for the frames in YUV 4:2:0 format. | 04-03-2014 |
20140341281 | Enhanced Intra-Prediction Coding Using Planar Representations - The present invention provides low complexity planar mode coding in which a first prediction value is calculated using linear interpolation between a value of respective horizontal boundary pixels and a value of one of vertical boundary pixels, and a second prediction value is calculated using linear interpolation between a value of respective vertical boundary pixels and a value of one of the horizontal boundary pixels. The first and second prediction values are then averaged to derive a respective prediction pixel value in a prediction block. A residual between the prediction block and a target block is signaled to a decoder. | 11-20-2014 |
