    摘要: A method of facilitating the self-administration of a directory of available modules on a group's syndicated customizable content document or start page is presented. The method includes presenting an initial list of modules to an administrator of a group, enabling the administrator to identify module selection information that identifies criteria for inclusion and/or exclusion of one or more modules in a directory, and storing the module selection information identified by the administrator. When a user of the group accesses a customized content document, the user is presented with a modified list of available modules based on the module selection information. Using this method, the administrator is capable of excluding modules from a global list, including only a specific subset of modules, or a combination of both. A system of carrying out the method is also presented.

    摘要: Disclosed herein are techniques and computer readable media containing instructions arranged to determine a bit allocation for a temporal base layer and at least one temporal enhancement layer. The techniques are enhanced to yield improved reproduced quality for the case where both a temporal base layer and at least one temporal enhancement layer is being used. An exemplary method for determining a bit allocation to one base layer includes initializing a bit allocation between the base layer and the at least one enhancement layer, determining a quality difference between the base layer and the at least one enhancement layer, expressed, for example, in the Quantizer Parameter of the last picture of each layer within a GOP, and determining a new bit allocation between the base layer and the at least one enhancement layer based on the quality difference and at least one constant factor.

    摘要: Disclosed are adaptive loop filtering techniques for video encoding and/or decoding. For a video unit, the encoder selects a set of predefined filters or generates a set of new filters, and places into the bitstream information identifying the set of predefined filters, or information defining the set of new filters. The set of filters may be used for loop filtering of at least one of the reconstructed samples of the video unit. At the decoder, a set of filters may be obtained by, decoding an index that identifies a set of predefined filters, or by decoding information related to a set of new filters. The obtained set of filters may be used for loop filtering of at least one decoded and reconstructed sample of the video unit.

    摘要: Systems and methods for using redundant pictures and slice groups to encode spatially scalable H.264 Baseline profile conformant video and to route that video to endpoints of varying capabilities without using the Scalable Video extension of H.264 or transcoding. Reduced resolution versions of primary coded pictures are encoded as slice groups in a full-resolution composite pictures, which are added to the video bitstream as redundant pictures. A router then processes the spatially scaled video bitstream into separate streams having different resolutions and routes these to endpoints of varying capabilities.

    摘要: Described are techniques in video coding and/or decoding that allow for selectively breaking prediction and/or in loop filtering across segment boundaries between different segments of a video picture. A high layer syntax element, such as a parameter set or a slice header, may contain one or more indications signalling to an encoder and/or decoder whether an associated prediction or loop filtering tool may be applied across the segment boundary. In response to such one or more indications, the encoder and/or decoder may then control the prediction or loop filtering tool accordingly.

    摘要: Disclosed are techniques for adaptive interpolation filtering of luminance and chrominance samples in the context of motion compensation in video encoding or decoding. A two-dimensional interpolation filter of n×m coefficients may be separable, i.e., it may be separated into two one-dimensional filters with m and n coefficients, respectively. The bitstream may include, per video unit and sub-sample position, information indicating whether to use a newly-generated, a cached, or a default filter that may be a separable two-dimensional filter. The information may be structured in a way that takes advantage of the two-dimensional filter being separable. When a newly-generated filter is signalled, the bitstream may contain information pertaining to the characteristics of the newly-generated filter, such as its coefficients. A decoder may fetch this information from the bitstream to create the filters which are applied to samples of the video unit. An encoder may create a bitstream as described.

    摘要: A system and method for adjusting a video bit rate (VBR) over a network includes reducing the VBR if the network incurs a packet loss (PL) that is greater than a PL threshold increasing the VBR if the PL is less than or equal to the PL threshold over a maximum integer number of time intervals and increasing the maximum integer number of time intervals if the PL is greater than the packet loss threshold at the increased VBR. In addition, the VBR is increased over consecutive time intervals until a maximum video bit rate is restored, if the PL over each consecutive time interval is less than or equal to the packet loss threshold.
