Abstract: In various examples, systems and methods are disclosed relating to error concealment by replacing a lost video frame region with a chronological predecessor. Network packets including data corresponding to an encoded bitstream of a frame of a video stream can be received. In response to determining that at least one packet of the video stream has been lost, a region of the video frame corresponding to the lost network packet can be replaced with the same region of a previous frame of the video stream.

Abstract: The present disclosure relates to streaming individual application windows and/or other desktop elements of a remote desktop. Data used to represent irrelevant desktop areas may be replaced with lower entropy data that may be highly compressed in a video stream and/or with data representative of other visual content. The video stream may also include desktop metadata (e.g., locations for desktop visuals, etc.) used to render the desktop elements on the local desktop. The desktop visuals of an application window may be rendered in a proxy window on the local desktop.

Abstract: A system and method for transmitting state based input over a network are presented. Embodiments of the present invention are operable to generate vector data comprising a composite of all state data associated with the state of all user input claims of a client system and transmit the vector data from the client device to a host device over a network. Embodiments of the present invention are further operable at the host device to determine a simulated input state at the client side by performing a comparison of the vector data currently received to a last known vector data and rendering output in response to the comparison.

Abstract: A method is enacted in a computer system operatively coupled to a hand-actuated input device. The method includes the action of determining automatically which form of user input to offer a process running on the computer system, the user input including position data from the input device. The method also includes the action of offering the position data to the process in the form determined.

Abstract: In various examples, systems and methods are disclosed relating to improving perceived video quality through temporal redistribution of network packet payloads that may carry error mitigation data. A subset of network packets for an encoded video stream is identified from a sequence of network packets as corresponding to a region of a video frame of the encoded video stream. A transmission order for the sequence of network packets is determined based at least on the subset of network packets and one or more error correction packets corresponding to the sequence of network packets. The sequence of network packets is transmitted to a receiver client device according to the transmission order.

Abstract: The disclosure relates to the transfer of per-pixel transparency information using video codecs that do not provide an alpha channel (alternatively referred to as “transparency-agnostic video codecs”). For example, alpha information of visual elements may be transcoded into the supported channels of a video stream to generate additional samples of a supported color space, which are representative of the alpha information. After being encoded by a “transparency-agnostic video codec” and transmitted, the received alpha information may then be extracted from the supported channels of the video stream to render the received visuals with corresponding per-pixel transparency.
