Abstract: Embodiments of the present disclosure relate to a remote desktop system which allows an application that executes on a remote computing device to be presented to a remote terminal as if the application is executing on the remote terminal. This system determines which of the remote computing device's application windows are top-level windows, and creates a rendering target for each top-level window. The rendering target is a graphics surface that is marshaled to the remote terminal. A PDU (Protocol Data Channel) is produced over this first graphics surface that includes a mapping of the location of the top-level window. A second graphics surface containing transparency information is created for a top-level window that contains a transparency characteristic. This second graphics surface is encoded and marshaled to the remote terminal separately from the first graphics surface. The client computing device receives and merges the two graphics surfaces, and renders a window with the expected transparency.

Abstract: Embodiments of the present disclosure provide for dividing a display area having rendered data thereon into a plurality of tiles and determining an update frequency for each tile. A determination is then made as to whether the update frequency of each tile exceeds a threshold. For each tile whose update frequency exceeds the threshold, that tile is marked as a candidate tile. Each of the adjacent candidate tiles are then associated to form a heat map. The heat map is then analyzed to determine whether to encode the rendered data associated with the heat map.

Abstract: Methods and systems for processing graphical data received at a computing system from a remote source are described. One method includes decoding received graphical content, the received graphical content including an image being compressed using a plurality of codecs, wherein decoding the received graphical content includes creating a decoded image. The method also includes, based on quality of the received graphical content, selecting from among a plurality of filters to apply to the decoded image. The method further includes applying a plurality of filters to at least a portion of the decoded image.

Abstract: Methods and systems for delivering screen content to a client device are disclosed. One method includes, for each of a plurality of coding units corresponding to screen regions included in a screen at a particular time, classifying screen content included in the coding unit as having a content type selected from among a plurality of content types, at least one of the content types comprising a screen image type, and, based on a determination that the screen content has a screen image type, applying a progressive standards-based encoding to the screen content of that coding unit. The method also includes transmitting encoded screen content for each of the screen regions to the client device.

Abstract: Methods and systems for processing chrominance of screen content, including up-conversion and down-conversion of screen content, are disclosed. One method includes down-converting chrominance of screen content at a computing device from a first format to a second format, the second format compatible with a video codec. The method also includes compressing the down-converted screen content in the second format using the video codec to generate compressed down-converted screen content. The method further includes transmitting the compressed down-converted screen content to a second computing device.

Abstract: An extensible remote display infrastructure is described that provides support for a competitive multi-vendor development environment. Application functionality may be partitioned to suit the needs of a given application and client-side functionality may be packaged in dynamic virtual channel plug-ins for remote display clients. Interactive coupling between the remote display clients and the dynamic virtual channel plug-ins may be facilitated by remote display client extensibility repositories. The remote display client extensibility repositories may be located within a communication infrastructure aspect of the extensible remote display infrastructure and, in particular, at a static virtual channel level. Dynamic virtual channel plug-ins may register properties, functionality and/or components with remote display client extensibility repositories at available granularity.
