20090077252 | Optimized Data Stream Compression Using Data-Dependent Chunking - Systems and methods for compression of data to be transmitted are described. A data stream, such as a byte code sequence, is partitioned into one or more data chunks. The data chunks can be associated with an identifier, such as a signature that differentiates one data chunk from the other. Thus, different data chunks would be identifiable through different signatures. The data chunks associated with the signatures can be compared with a repository or a history buffer. The history buffer includes a collection of previously transmitted data chunks each associated with their respective signature. | 03-19-2009 |
20090195537 | GRAPHICS REMOTING ARCHITECTURE - Systems and methods to implement a graphics remoting architecture for rendering graphics images at remote clients are disclosed. In one implementation, when a D3D application hosted on a remote server is used by a remote client, the graphics associated with the D3D application are created and rendered at the remote client. For this, the D3D commands and D3D objects corresponding to the graphics are abstracted into data streams at the remote server. The data streams are then sent to the remote client. At the remote client, the D3D commands and D3D objects are extracted from the data streams and executed to create the graphics images. The graphics images are then rendered and displayed using output devices at the remote client. | 08-06-2009 |
20090210482 | Framework for Rendering Plug-ins in Remote Access Services - A framework for and hosting rendering plug-ins in remote access services is disclosed. The framework provides an interface between the core components of the remote access system and the rendering plug-ins. The framework utilizes public APIs to provide the interface between the core components and the rendering plug-ins. Using the APIs, the framework can allow various existing and new rendering plug-ins to interact with the core components of the remote access system, thereby making an extensible system that can support a variety of rendering plug-ins. | 08-20-2009 |
20090210811 | DRAGGING AND DROPPING OBJECTS BETWEEN LOCAL AND REMOTE MODULES - The present invention extends to methods, systems, and computer program products for dragging and dropping objects between local and remote modules. Terminal server components simulate the functionality of participants in drag and drag operations to facilitate the dragging and dropping of objects between local and remote modules and vice versa. The terminal server components interact locally to communicate with modules participating in a drag and drop operation. The terminal server components also send messages over a terminal server session to relay appropriate drag and drop information to corresponding terminal server components on the other end of the terminal server session. | 08-20-2009 |

20110185068 | MULTI-LINK REMOTE PROTOCOL - In various embodiments, a remote client is allowed to access at least a part of a connection service located on alternate sources other than the primary remote presentation server. In some embodiments, the remote presentation virtual channels may be split into multiple connections with the purpose of allowing better flow control. Some embodiments may be implemented in a virtual machine environment for cases in which the data to be transferred through a data channel is located in the host virtual machine partition but the remote endpoint is located on the guest virtual machine partition. | 07-28-2011 |
20110185071 | LOSS TOLERANT PROTOCOL FOR REMOTING DESKTOP GRAPHICS - In various embodiments, remote presentation encoding techniques may be modified in such a way that the data can be transmitted over transports without guaranteed packet delivery. In one embodiment, the desktop graphics data may be encoded in individual frames, each frame comprising self-contained graphics elements that fit in a small number of User Datagram Protocol (UDP) protocol data units (PDUs). The PDUs may then be sent to the client on a separate lossy link instead of the lossless link. On the client side, the client may detect which graphic elements within a frame were “lost” as a result of dropped UDP packets and request a refresh from the server through the lossless channel. | 07-28-2011 |
20110197151 | GRAPHICS REMOTING USING AUGMENTATION DATA - Methods and systems are disclosed in which bitmap data transmission is improved by using some of the advantages of primitive remoting, thus allowing for the reduction of the bandwidth and processing needed to remote a virtual desktop experience. In an embodiment, rendering is performed and bitmaps are remoted, but metadata comprising shortcuts or hints are provided to assist in the rendering of the bitmap data. | 08-11-2011 |
20110219122 | REMOTE CONTENT CLASSIFICATION AND TRANSMISSION USING MULTIPLE TRANSPORT CHANNELS - In various embodiments, methods and systems are disclosed for the implementation of multiple transport channels between the client and server. Each of the channels may be adapted to efficiently communicate data for a particular data type and thus be particularly well suited for its data-element characteristics and the detected link characteristics between the client and server. | 09-08-2011 |
20110219287 | REMOTE PRESENTATION OVER LOSSY TRANSPORT WITH FORWARD ERROR CORRECTION - 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. | 09-08-2011 |

20120082395 | Entropy Coder for Image Compression - 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. | 04-05-2012 |
20120275697 | PRE-PROCESSING OF IMAGE DATA FOR ENHANCED COMPRESSION - Embodiments herein provide for a pre-processing stage or mechanism for enhancing data compression of an image by splitting or separating the color channels for pixels into planar data sources. Typically, image data is displayed as an interleaved set of channel types for a color space such that each pixel within an image (such as a bitmap) has one component for each color channel. By separating the interleaved bitmap into a planar representation, each plane can be compressed independently and often times achieve higher compression ratios. This is especially true for channels that are expected to stay fairly constant throughout the bitmap most of the time. The utilization of the above embodiment can be further enhanced through manipulation of channel data or through converting the color space from one form to another. | 11-01-2012 |
