摘要： Innovations in the area of prediction of block vector ("BV") values improve encoding or decoding of blocks using intra block copy ("BC") prediction. For example, some of the innovations relate to use of a default BV predictor with a non-zero value. Other innovations relate to use of a selected one of multiple BV predictor candidates for a current block. Still other innovations relate to use of a skip mode in which a current intra-BC-predicted block uses a predicted BV value.

摘要： An invention is disclosed for conducting a remote presentation session with a client that uses a web browser to conduct the session. In embodiments, a proxy server exists between the remote presentation server and the client. The proxy server establishes a HTTP session with the client and a remote presentation session with the client. The server generates graphics encoded with a remote presentation protocol and sends them to the proxy, which re-encodes them as video and sends them to the client for display in the web browser. The client captures user input at the web browser and sends it to the proxy, which encodes it with the remote presentation protocol and sends it to the server to be processed.

摘要： Methods and systems for processing graphical data received at a computing system from a remote source are described. At the remote source, text portions of the remote screen to be compressed and transmitted have applied thereto e.g. a lossless codec, while image and background data have applied thereto a proogressive codec, or optionally e.g. MPEG-4 AVC/264. At the receiving computing system, the subsequently received graphical content are decoded, wherein decoding the received graphical content includes creating a decoded image. During post-processing, one or more of a plurality of filters, including e.g. an asymmetric deblocking filter (602), a bilateral filter (606) and a peaking filter (604), may be applied to decompressed graphical content from one or more regions of the screen as received from decoders. In said post-processing, if a region of the decompressed graphical content is considered to be of middle quality, a plurality of filters are applied to that region in e.g. a first order (600). Alternatively, if the quality of the region is considered to be of a low quality, the plurality of filters are applied in a second order (700). Otherwise, if a region under consideration is considered to be of a high quality then either: no filter is applied; or only an asymmetric deblocking filter is applied.

摘要： A method for removing boundary distortion includes receiving a one-dimensional input signal and determining whether the one-dimensional input signal includes an even number of data elements. If the one-dimensional input signal includes an even number of data elements, an extrapolation operation is performed on one of a first or second boundary of the one-dimensional input signal. The extrapolation operation produces one additional data element. The method may further include performing a mirroring operation on the signal data resulting from the extrapolation operation to produce a mirrored signal, and performing a transform operation the mirrored signal.

摘要： 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.
摘要翻译：出于视频编码的目的，诸如YUV 4：4：4的更高分辨率色度采样格式的视频帧被打包成较低分辨率色度采样格式的视频帧，例如YUV 4：2：0。例如，YUV 4：4：4格式的帧的样本值以YUV 4：2：0格式打包成两帧。在解码之后，可以解压缩较低分辨率色度采样格式的视频帧以重构更高分辨率色度采样格式的视频帧。以这种方式，可以使用以较低分辨率色度采样格式工作的可用编码器和解码器，同时仍然保留更高分辨率的色度信息。在示例实现中，YUV 4：4：4格式的帧以YUV 4：2：0格式打包成帧，使得在YUV 4：2：0格式的帧中的Y，U和V分量之间保持几何对应。

摘要： An invention is disclosed for encoding and decoding data in a 4:4:4 subsampling scheme, using an encoder/decoder that is not configured to encode or decode data in 4:4:4. In embodiments, an encoder planararizes an input frame into three component frames in a 4:0:0 scheme. The encoder then encodes each component frame in the 4:0:0 scheme, and aggregates the encoded component frames into a bit stream. A decoder receives such a bit stream, and decodes it with a component not configured to decode data in 4:4:4. The decoder decodes the bit stream to produce a representation of the three component frames in 4:0:0, then aggregates the three component frames into a representation of the original frame in 4:4:4.
