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： In various embodiments, methods and systems are disclosed for integrating a remote presentation protocol with a datagram based transport. In one embodiment, an integrated protocol is configured to support lossless or reduced loss transport based on Retransmission (ARQ) combined with Forward Error Correction (FEC). The protocol involves encoding and decoding of data packets including feedback headers and FEC packets, continuous measurement of RTT, RTO and packet delay, dynamically evaluating loss probability to determine and adjust the ratio of FEC, congestion management based on dynamically detecting increase in packet delay, and fast data transmission rate ramp-up based on detecting a decrease in packet delay.

摘要： In various embodiments, methods and systems are disclosed for a hybrid rate plus window based congestion protocol that controls the rate of packet transmission into the network and provides low queuing delay, practically zero packet loss, fair allocation of network resources amongst multiple flows, and full link utilization. In one embodiment, a congestion window may be used to control the maximum number of outstanding bits, a transmission rate may be used to control the rate of packets entering the network (packet pacing), a queuing delay based rate update may be used to control queuing delay within tolerated bounds and minimize packet loss, and aggressive ramp-up/graceful back-off may be used to fully utilize the link capacity and additive-increase, multiplicative-decrease (AIMD) rate control may be used to provide fairness amongst multiple flows.

摘要： An invention is disclosed for classifying a graphic—e.g. as text or non-text. In embodiments, machine learning is used to generate a solution for classifying graphics of a graphic based on providing the machine learning system a plurality of graphics that are already classified. The way to determine a classification is then used by a remote presentation session server to classify tiles of frames to be transmitted to a client in a remote presentation session. The server encodes the tiles based on their classifications and transmits the encoded tiles to the client.

摘要： Data can be streamed from a server to a client via an established connection. Commands (e.g., commands to navigate the streamed data) can be communicated to the server and streaming can continue (possibly from a different location) without breaking the connection. In one implementation, the connection is an HTTP 1.1 (HyperText Transfer Protocol version 1.1) connection.

摘要： A display area having rendered data thereon is divided into a plurality of tiles and an update frequency for each tile is determined. A determination is then made as to whether the update frequency of each tile exceeds a threshold. For each tile whose update frequency exceeds the threshold, that tile is marked as a candidate tile. Adjacent candidate tiles are then associated to form a heat map. The heat map is then analyzed to determine whether to encode the rendered data associated with the heat map.
