Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: The present invention allows higher quality video images to be transmitted without a concomitant increase in a total number of video data bits transmitted per frame. Quantization parameters are applied to coefficients of macroblocks within a given video frame. A lower value of the quantization parameter is applied near a central region of a video frame. This central region is referred to as a prime video region. Applying the lower quantization parameter to the prime video region has the effect of increasing the video data bit density within that area. Outside of the prime video region, the video data bit density per macroblock is decreased so as to have a zero net-gain in bit density over the entire video frame. Furthermore, there may be a plurality of prime video regions where quantization parameters are dynamically coded. In this case, the value of the quantization parameter will increase or decrease within a given prime video region based on a relative importance of a particular prime video region. Consequently, a quantization parameter matrix may vary depending on the video scene.

Abstract translation: 本发明允许传输更高质量的视频图像，而不伴随每帧传输的视频数据比特数的总和增加。 量化参数被应用于给定视频帧内的宏块的系数。 在视频帧的中心区域附近施加较低的量化参数值。 该中心区域被称为主要视频区域。 将较低量化参数应用于主视频区域具有增加该区域内的视频数据位密度的效果。 在主视频区域之外，每个宏块的视频数据比特密度减小，从而在整个视频帧上具有零比特密度的净增益。 此外，可以存在多个主要视频区域，其中量化参数被动态地编码。 在这种情况下，基于特定主要视频区域的相对重要性，量化参数的值将在给定的主视频区域内增加或减少。 因此，量化参数矩阵可以根据视频场景而变化。
