摘要： Techniques are provided for establishing a Unified Communications (UC) session between a client endpoint device and remote endpoint devices, the client endpoint device managing the session using a first-party call control protocol in response to commands from a third-party control protocol and user input. A hosted virtual desktop (HVD) generates an HVD image and communicates it to the client endpoint device for display, via a virtual desktop interface (VDI) protocol. The HVD image comprises a UC user interface generated by a UC application on the HVD, the user interface comprising at least one user interface element and at least one placeholder where a client-provided user interface element may be inserted. A client UC application receives the HVD image and inserts client-provided user interface elements over the placeholders before sending the integrated image to a client operating system to be rendered on the display of client endpoint device.

摘要： Techniques are provided for establishing an integrated and transparent overlay of a browser window for rendering data such as streaming media on a client endpoint device. A web browser on a Hosted Virtual Desktop (HVD) draws HVD display image comprising a browser window and communicates it to the client endpoint device for display, via a virtual desktop interface (VDI) protocol. The browser window comprises zero or more host-provided window elements such as a window frame and at least one placeholder element where a client-provided frameless browser window may be rendered. A browser (or browser extension) on the HVD works together with a browser server on the client endpoint device to render data such as streaming media in the client-provided frameless browser window in place of the placeholder, before displaying the frameless browser window and the HVD display as an integrated display at the client endpoint device.

摘要： Techniques are provided for using a middlebox to composite displays from multiple hosted virtualized applications (HVAs) for transmission to a client endpoint device. The middlebox receives one or more HVA displays via a virtual desktop interface (VDI) protocol, each HVA display from an individual HVA. The middlebox renders and composites the HVA displays together into a hosted virtual desktop (HVD) display, and sends the HVD display to the client endpoint device via a VDI protocol. The client endpoint device is therefore able to display a composite image of multiple HVA displays even if it is a zero client endpoint lacking the capability to perform compositing itself. In some examples, the middlebox reduces computational load by reducing the HVD frame rate, so that it is able to maintain HVD functionality during times of high system activity.

摘要： Techniques are provided herein for providing survivable browsing when a client endpoint device loses contact with its host server. A Hosted Virtual Desktop (HVD) draws and communicates an HVD display image comprising a HVD browser window to the client endpoint device for display, via a virtual desktop interface (VDI) protocol. A browser (or browser extension) on the HVD works together with a browser server on the client endpoint device to synchronize browser data, and in some examples to render data such as streaming media in a client-provided frameless browser window in place of a placeholder in the HVD browser window. In response to the detection of an inactive VDI session, the browser server on the client endpoint device launches an endpoint browser instance to seamlessly switch browsing from the HVD browser window to an endpoint browser window, using the browser synchronization data.

摘要： According to an embodiment of the present invention, an apparatus for performing video conferencing is provided that includes an I-frame injector element operable to intercept I-frame requests from one or more end points and to attempt to service the I-frame requests such that at least a portion of the requests are prevented from propagating back to an originating sender. In more specific embodiments, when a receiver endpoint sends a fast video update (FVU) request upstream, it is intercepted by the I-frame injector element and rather than passing the FVU request to the sender the I-frame injector element replaces a next P-frame from the sender with an I-frame, whereby the I-frame is constructed so that when decoded, it matches the P-frame that it replaced. In still more detailed embodiments, the I-frame injector element operates in one of three modes that are associated with bandwidth parameters.

摘要： In one embodiment, a system includes a video mixer coupled with an audio mixer for exchange of information that includes a first set of delay values respecting input audio streams received by the audio mixer from a plurality of source endpoints, and output audio streams sent from the audio mixer to a plurality of destination endpoints. The information further including a second set of delay values respecting the corresponding input video streams. The audio mixer calculates end-to-end video delays, and the video mixer calculates end-to-end audio delays. The audio mixer delays the output audio streams to equalize the end-to-end audio and video delays in the event that the end-to-end audio delays are less than the end-to-end video delays, and the video mixer delays the output video streams to equalize the end-to-end audio and video delays in the event that the end-to-end video delays are less than the end-to-end audio delays.
