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： 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.

摘要： Example embodiments of the present disclosure provide techniques for efficiently processing and transmitting graphics data when sub-regions of the screen represented by the graphics data are updated at different relative update rates. In an embodiment, when the screen is divided into tiles and a plurality of the tiles have been determined as being changed, some of the sublevels resulting from the image transform may not be encoded and transmitted. The decoding process may use zeroes for any data not received. The rendering subsystem may render the image with the partial data, and the remaining data may be received in subsequent transmissions.

摘要： An invention is disclosed for performing differencing of graphical data in post-transform space for a remote presentation session. Graphical data is transformed from a first representation to a second representation (e.g. with a DWT), and then a difference is taken of the post-transform data and the post-transform data of the frame that preceded the current frame. This difference is then encoded and transmitted to a client, which decodes it, and creates a representation of the graphical data using the delta, and a previously determined representation of the previous frame. By performing differencing in post-transform space, fidelity of the remote presentation session is retained while it may decrease bandwidth. This may occur because the entropy of the delta representation is usually lower than a non-delta representation while the scheme retains the identical data of the final decoded image of the non-delta version of the same compression scheme.
摘要翻译：公开了一种用于在远程呈现会话的后变换空间中执行图形数据的差异的发明。将图形数据从第一表示变换到第二表示（例如，具有DWT），然后对当前帧之前的帧的后变换数据和后变换数据进行区别。然后将该差异编码并发送到客户端，客户端对其进行解码，并使用增量和先前确定的前一帧的表示来创建图形数据的表示。通过在后变换空间中执行差分，保留远程呈现会话的保真度，同时可以减少带宽。这可能是因为Δ表示的熵通常低于非增量表示，而该方案保留相同压缩方案的非增量版本的最终解码图像的相同数据。

摘要： An invention is disclosed for efficiently processing and transmitting graphics data in a remote desktop environment. In embodiments of the invention, a connection is established between a remote desktop server computer and a remote desktop client computer. The remote desktop server computer may process graphics data representative of a remote user desktop. The remote desktop server computer may divide the remote desktop screen in data regions and portions. The remote desktop server computer may then encode and transmit each region to the remote desktop client computer at a certain quality that may be adjusted progressively across the screen frames. The remote desktop server computer may also stop encoding and transmitting the portions of the data region that would not be visible to a user when the region is rendered on a display. The remote desktop user experiences an image quality gradually improving with each frame containing information about the image.

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 performing entropy encoding in a parallelized manner, using a GPU. In embodiments, an input sequence of integers is received, and run-length encoding is performed on any runs of zeros in parallel operations on the GPU. Then, a plurality of parallelized operations are performed on the run-length encoded sequence to entropy encode the sequence. The value N may be entropy encoded using only N and the value that precedes it in the sequence, N−1, so the encoding may be sub-divided into multiple operations that may be performed in parallel on the GPU. After entropy encoding is performed, a bitstream may be produced using parallelized operations on the GPU.
摘要翻译：公开了一种使用GPU以并行方式执行熵编码的发明。在实施例中，接收整数的输入序列，并且对GPU上的并行操作中的任何零运行执行游程编码。然后，对游程长度编码序列执行多个并行操作，以对该序列进行熵编码。值N可以仅使用N进行熵编码，并且可以在序列N-1中进行熵编码，因此编码可以被细分为可以在GPU上并行执行的多个操作。在执行熵编码之后，可以使用GPU上的并行操作来产生比特流。
