Abstract: A method for communicating an image stream, one embodiment comprising negotiating, between a server and client, an MTCC identifying: a window as a portion of a display of the client, and an occluded portion of the window defined by the client; generating, by the server, complying with the MTCC, a sequence of image frames each comprising pixel data in a portion of the frame identified by the occluded portion; transmitting an encoding of a first frame of the sequence not including an encoding of the pixel data in the portion of the first frame; identifying, by the server, an event associated with the sequence; and transmitting, before communication between the server and the client regarding the event, by the server, information of the event in conjunction with an encoding of a second frame of the sequence including an encoding of the pixel data in the portion of the second frame.

Abstract: A method and apparatus for motion determination comprising generating a hash value for each changed pixel in a frame of an image display sequence, the changed pixels indicated in a set of sparse display coordinates, for each changed pixel, overwriting (X, Y) information at a position in a symbol table indexed by the hash value, the (X, Y) information comprising one display coordinate associated with the each changed pixel, generating motion vectors for a frame, each motion vector specifying a pixel area determined from at least one (X, Y) delta between one of the changed pixels represented in the symbol table and a previously changed pixel represented at the position in a previous frame symbol table for a previous frame in the image display sequence, and transmitting the motion vectors from the host computer over a network to a client computer.

Abstract: A method and apparatus for transmitting a desktop display comprising classifying a first region of the desktop display as persistently changed and a second region of the desktop display as sporadically changed, adjusting, in relation to a user experience (UX) bias and a resource constraint, a target image quality for the first region, decimating the first region in accordance with a spatial decimation factor to generate a first decimated region, compressing the first decimated region at the target image quality and compressing the second region to generate a plurality of compressed regions and transmitting the plurality of compressed regions to a client via an IP network.

Abstract: A method and apparatus for sequencing remote desktop connections. In one embodiment, the method comprises receiving, at a processor, a session exchange request from a first client in a first connection to a remote desktop; selecting, by the processor, a second client for connection to the remote desktop based on the session exchange request; configuring, by the processor, the second client; and orchestrating, by the processor, a second connection between the second client and the remote desktop.

Abstract: A method and apparatus for endpoint configuration management comprising receiving an endpoint topology and storing the endpoint topology in a configuration store, modifying a configuration for a remote session to conform to the endpoint topology and corresponding the configuration to the endpoint topology in the data structure and presenting to the endpoint the modified configuration of the remote session.

Abstract: A method and apparatus for transferring data from a first to a second memory of a computer system. The method comprises (i) initializing a descriptor with a description of physical addressing of a first section of a first array of the first memory; (ii) updating a mask associated with the descriptor with an indication for transferring data from a first sub-section of the first section to the second memory, the mask and the data managed by an application on a first virtual machine of the computer system, the application isolated from the physical addressing of the first section; (iii) responsive to the updated mask, (a) determining physical addresses of the first sub-section based on the description, and (b), transferring the data from the first sub-section to the second memory; and (iv) clearing at least a portion of the updated mask to indicate completion of transferring the data.
