摘要： Example embodiments of the present disclosure provide for a fast entropy coder / decoder for use in real time image compression. A method of processing graphics data for transmission to a remote computing device may comprise receiving graphics data representative of a client screen to be rendered, receiving information indicative of available bandwidth for transmission and, based on the information, determining that the available bandwidth meets a predetermined threshold, and entropy encoding the graphics data using a fixed bit size encoding stream, wherein runs of zeroes are encoded in a variable number of units of the fixed bit size, and literal values are encoded using one of an entry in a cache of recently used literal values or a variable number of units of the fixed bit size.

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： Systems, methods and computer readable media are disclosed for reducing the tearing of display data received across a communications network. A server determines at least two logically related drawing orders in an order heap and warps those orders with a begin marker and an end marker. It sends those wrapped orders across the communications network to a client. The client receives those orders and renders them to a shadow buffer. When the client processes the end marker, it moves the drawing orders in the shadow buffer to a client display surface.

摘要： Techniques are disclosed for a user-mode based remote desktop protocol (RDP) encoding architecture. A user mode desktop application and user mode virtual channel application run in user-mode session space. Virtual channel data from the virtual channel application is marshaled and sent to a RDP encoder process in user-mode system space. There it is converted to RDP protocol data units (PDU) and sent to a remote client across a communications network. Graphics data from the desktop application is sent to a display driver in kernel-mode session space and then to a graphics reflector that marshals the graphics data and sends it to the RDP encoder for a similar transformation.

摘要： Techniques are disclosed for acceleration techniques for improved image remoting. A rolling 2D hash of a first image sent to a client is computed. When the server has a second image to send to the client, it calculates a rolling 2D hash of the new image. It also calculates "pivot points" for the images based on the rolling 2D hashes. Based on the pivot points, it determines possible matching hash windows between the two images that correspond to window moves or scrolls. Where a match is confirmed, it determines whether a "larger" a larger matching rectangle exists between the two images. It then instructs the client to display the matching rectangle that exists in the first image that the client has in the appropriate location in the second image, thereby saving the bandwidth requirements to re-transmit it to the client.

摘要： Systems, methods and computer readable media are disclosed for accelerating the compression of images on a multi-processor computer. In an embodiment, an image is divided into a plurality of slices, each slice having the same width as the image. These slices are provided to a work manager that maintains a thread for each processor. The work manager assigns each slice to a thread for processing in an efficient manner (such as the thread corresponding to the first available processor), and when an indication that the slice has been compressed for each slice is received, the work manager assembles the compressed image.

摘要： Systems, methods and computer readable media are disclosed for a vectorized tile differencing algorithm for a remote desktop protocol (RDP). A server executes a CBC-variant vectorized hash algorithm that is used to produce a big key that identifies the tile, and keeps track of these big keys. Where a serial version of the algorithm operates on a single portion of the image at once - such as 32 bits - the vectorized algorithm operates on a plurality of these portions simultaneously. Where the server identifies that a tile has already been sent to a client via RDP because it has a second big key that matches the big key, it sends the big key to the client - which caches received tiles - and the client uses it to access the proper tile for display. Where the server identifies that a tile has not already been sent to the client, it sends the client the tile.
