Abstract: Methods and systems for determining performance of a hosted application are described herein. Determining the performance of a hosted application may require the calculation of scores corresponding to metrics about user experience, including a user workload context, a user action, a frame rate, a round trip latency time, and image quality. The scores associated with the metrics about user experience may be weighted against each other, in accordance with an equation, described herein, to calculate a value corresponding to the performance of a hosted application. Data may be generated and shared with both a virtual computing environment and an administrator of the virtual computing environment. The data may include instructions to optimize user experience within the virtual computing environment. The instructions may be executed by the virtual computing environment to prepare the virtual computing environment for further user interaction.

Abstract: A computing system includes a virtual server providing first and second virtual desktops. A first client computing device accesses the first virtual desktop via a communications network, and shares content of the first virtual desktop as a screen sharer in a collaboration session. A second client computing device accesses the second virtual desktop via the communications network, and displays content of the second virtual desktop in a virtual desktop window. The second client computing device participates in the collaboration session as a screen viewer, and receives the shared screen content of the first virtual desktop. The shared screen content is displayed by the second client computing device in a shared screen window, with the shared screen window being separate from the virtual desktop window.

Abstract: Systems and methods for stream-based compression are described. One example is an encoder of a first device that receives an input stream of bytes including a first byte preceded by one or more second bytes. The encoder may determine to identify a prefix code for the first byte. The encoder may select a prefix code table using the one or more second bytes. The encoder may identify, from the selected prefix code table, the prefix code of the first byte. The encoder may generate an output stream of bytes by replacing the first byte in the input stream with the prefix code of the first byte. The encoder may transmit the output stream from the encoder of the first device to a decoder of a second device. The output stream may have a fewer number of bits than the input stream.

Abstract: A method may include receiving, from a first client device, a first position of a selection event at the first client device. The first client device being engaged in a web conference session with a second client device. The second client device sharing a content displayed at the second client device such that the content is also displayed at the first client device. If the first position of the selection event is determined to correspond to a second position of a resource link included in the content being shared by the second client device, information associated with the resource link may be sent to the first client device. The information may enable the first client device to access a resource associated with the resource link by launching a corresponding application such as a browser, a media player, and/or a text editor. Related systems and articles of manufacture are also provided.

Abstract: Systems and methods for supporting multiple local browser tabs and windows during a remote browser session are described. A remote browser session may be, in some examples, a remote session accessed in a local browser tab with inputs to the remote session launching web pages and applications on a server rather than locally on a device. In some remote browser session experiences, further interactions with the launched web pages and applications may be limited to being within the local browser tab. The user can instead utilize functionality and methods where applications and browser windows can be started in or moved to individual tabs or windows of the local browser. Then those different tabs and windows may be selected to switch between applications and/or web sites that are running in a shared remote session on a server saving server resources.

Abstract: Systems and methods are provided for encoding a multi-pixel caching scheme for lossless encoders. The systems and methods can include obtaining a sequence of pixels, determining repeating sub-sequences of the sequence of pixels consisting of a single repeated pixel and non-repeating sub-sequences of the sequence of pixels, responsive to the determination, encoding the repeating sub-sequences using a run-length of the repeated pixel and encoding the non-repeating sub-sequences using a multi-pixel cache, wherein the encoding using a multi-pixel cache comprises, encoding non-repeating sub-sequences stored in the multi-pixel cache as the location of the non-repeating sub-sequences in the multi-pixel cache, and encoding non-repeating sub-sequences not stored in the multi-pixel cache using the value of the pixels in the non-repeating sub-sequences.

Abstract: A computing system may receive, from a client device, data associated with a file to be uploaded to the computing system, and may determine, based at least in part on the received data, a recommended compression technique to be used on the file. The computing system may send an indication of the recommended compression technique to the client device. The computing system may receive, from the client device, a version of the file that is compressed in accordance with the recommended compression technique.

Abstract: Described embodiments provide systems and methods for stream-based compression. An encoder of a first device receives an input stream of bytes including a first byte preceded by one or more second bytes. The encoder may determine to identify a prefix code for the first byte. The encoder may select a prefix code table using the one or more second bytes. The encoder may identify, from the selected prefix code table, the prefix code of the first byte. The encoder may generate an output stream of bytes by replacing the first byte in the input stream with the prefix code of the first byte. The encoder may transmit the output stream from the encoder of the first device to a decoder of a second device. The output stream may have a fewer number of bits than the input stream.

Abstract: Systems and methods for providing a visible watermark in a remote session. The methods comprise: determining if a graphic update needs to be made at a client computing device during the remote session; generating a first graphic update message in response to a determination that a graphic update is needed; identifying pixels of the graphic which would be affected by at least one watermark if the graphic and watermark were both displayed on a screen of the client computing device; constructing a second string of commands specifying a new color value for each of the pixels that were previously identified; converting the first graphic update message to a second graphic update message by inserting the second string of commands in between a first string of commands and an End-Of-Frame (“EOF”) command; and communicating the second graphic update message from the sever to the client computing device.
