摘要： Embodiments of the present invention provide apparatuses and methods of coding video. The apparatuses and methods may further provide coding a source video sequence according to a block-based coding process, estimating processing capabilities of a target decoder, determining if the estimated processing capabilities are sufficient to perform deblocking filtering. If not sufficient, the apparatuses and methods may provide computing deblocking filter strengths for pixel blocks of the source video sequence to be used at decoding, and transmitting the deblocking filter strengths in a coded video data signal with the coded video data. Moreover, if not sufficient, the apparatuses and methods may provide changing coding parameters including, but not limited to, block sizes, transform sizes, and Qmatrix.

摘要： Systems, apparatuses and methods whereby coded bitstreams are delivered to downstream end-user devices having various performance capabilities. A head-end encoder/video store generates a primary coded bitstream and metadata for delivery to an intermediate re-encoding system. The re-encoding system recodes the primary coded bitstream to generate secondary coded bitstreams based on coding parameters in the metadata. Each secondary coded bitstream is matched to a conformance point of a downstream end-user device. Coding parameters for each conformance point can be derived from the head-end encoder encoding original source video to generate the secondary coded bitstreams and extracting information from the coding process/results. The metadata can then can be communicated as part of the primary coded bitstream (e.g., as SEI) or can be communicated separately. As a result, the complexity of the secondary coded bitstream is appropriately scaled to match the capabilities of the downstream end-user device to which it is delivered.

摘要： A first improvement is described for prediction of motion vectors to be used in prediction of video data for enhancement layer data. Arbitrary pixelblock partitioning between base layer data and enhancement layer data raises problems to identify base layer motion vectors to be used as prediction sources for enhancement layer motion vectors. The disclosed method develops enhancement layer motion vectors by scaling a base layer pixelblock partition map according to a size difference between the base layer video image and the enhancement layer video image, then identified scale base layer pixelblocks that are co-located with the enhancement layer pixelblocks for which motion vector prediction is to be performed. Motion vectors from the scaled co-located base layer pixelblocks are averaged, weighted according to a degree of overlap between the base layer pixelblocks and the enhancement layer pixelblock. Another improvement is obtained by filtering recovered base layer image data before being provided to an enhancement layer decoder. When a specified filter requires image data outside a prediction region available from a base layer decoder, the prediction region data may be supplemented with previously-decoded data from an enhancement layer at a border of the prediction region.
摘要翻译：描述了用于预测要用于预测增强层数据的视频数据的运动矢量的第一个改进。基本层数据与增强层数据之间的任意像素块划分引起了问题，以识别要用作增强层运动向量的预测源的基本层运动向量。所公开的方法通过根据基础层视频图像和增强层视频图像之间的大小差异来缩放基础层像素块分割图来开发增强层运动向量，然后识别与增强层像素块共同定位的缩放基础层像素块针对哪个运动矢量预测将被执行。根据基础层像素块与增强层像素块之间的重叠程度对来自缩放后的共同定位基础层像素块的运动向量进行平均，加权。通过在提供给增强层解码器之前过滤恢复的基本层图像数据来获得另一改进。当指定过滤器需要可从基础层解码器获得的预测区域之外的图像数据时，预测区域数据可补充来自预测区域边界处的增强层的先前解码的数据。

摘要： Some embodiments provide a method for encoding a first set of pixels in a first image by reference to a second image in a video sequence (See Fig. 7, items 700 and 705). In a first search window within a second image, the method searches to identify a first particular portion in the second image that best matches the first set of pixels in the first image (See Fig. 7, item 715). In the first search window within the second image, the method identifies a first location corresponding to the first particular portion (See Fig. 7, item 710). In a second search window within the second image, the method then searches to identify a second particular portion in the second image that best matches the first set of pixels in the first image (See Fig. 7, item 720), where the second search window is defined about the first location (See Fig. 7, item 735).

摘要： Some embodiments of the invention provide a multi-pass encoding method that encodes several images (e.g., several frames of a video sequence). The method iteratively performs an encoding operation that encodes these images (Figure 1, 110). The encoding operation is based on a nominal quantization parameter, which the method uses to compute quantization parameters for the images (132). During several different iterations of the encoding operation, the method uses several different nominal quantization parameters (125). The method stops its iterations (140) when it reaches a terminating criterion (e.g., it identifies an acceptable encoding of the images).
