Abstract: A converter can process image data from input HDR images in real time to compute new metadata about the brightness, contrast, color gamut and/or color volume for the image data to be displayed from each frame. Existing metadata can be ignored. The converter can combine the metadata for a current HDR frame with metadata for a plurality of immediately previous sequential frames to provide parameters for tone mapping. The converter uses these parameters, and characteristics about a lower dynamic range display which will receive output image data, to define a transfer function for converting the input HDR image data into output image data for display. The converter analyzes and tone maps HDR frames at a rate sufficient to allow output video to be generated at a desired frame rate while receiving the image data from frames of the input HDR video at an input frame rate.

Abstract: A game engine may generate video and audio content on a per-frame basis. Audio data corresponding to a current frame may be generated to comprise sound-field information independent of a speaker configuration or spatialization technology that may be used to play the associated audio. The sound-field may be generated based on monaural audio data corresponding to a sound produced by an in-game object at the object's position as of the current frame. The sound-field information may be transmitted to a remote computing device for reproduction using a selected, available speaker configuration and spatialization technology.

Abstract: A gaming console composites a camera video overlay on gameplay video for broadcasting such that the gameplay area that is rendered by the gaming console is not obscured, even when the camera video overlay is composited on the gameplay video for broadcasting. The gaming console or a companion device of the gaming console can also allow a user to specify placement of the camera video overlay on the gameplay video for broadcasting, permitting the user to choose the portion of the gameplay video for broadcasting that is obscured by the camera video overlay.

Abstract: A video game application is executed on a computer gaming device. While the video game application is providing active gameplay, the computer gaming device receives a command to broadcast the active gameplay. Responsive to the command, the computer gaming device broadcasts the active gameplay without interrupting the active gameplay.

Abstract: An electronic marketplace includes a plurality of video game applications available for purchase. For each of the plurality of video game applications, the electronic marketplace may display a tile identifying the video game application, a payment object for initiating a purchase of the video game application, and a preview object to initiate viewing of a live broadcast of active gameplay of the video game application.

Abstract: While broadcasting active gameplay of the video game application with a first broadcast configuration, a computer gaming device receives a command to change the broadcast configuration to a second broadcast configuration. Responsive to the command, the computer gaming device begins broadcasting the active gameplay with the second broadcast configuration without interrupting active gameplay or broadcasting of active gameplay.

Abstract: A method of accessing a first computing device from a second computing device using a remote desktop service is disclosed. The first and second device register are authenticated and registered with a remote access gateway. In some embodiments, the remote access gateway stores a copy of the first computer and changes made to the copy are synchronized with the actual first computer when it access the remote access gateway. A virtual operating system experience on the second computer is virtually the same as the real operating system experience on the first computer.

Abstract: The claimed invention adapts an existing operating system native replication service component to interface with a general application running on a peer-to-peer network. The claimed invention provides the general application with replication services without the need for coding this functionality from scratch. The claimed invention also adapts the replication service functionality to create a topology of connections based on information received from a peer-to-peer network component, thereby making the replication service function more efficiently with a peer-to-peer network.

Abstract: A series of unique records may be published to establish and maintain ad hoc or online meetings on a peer-to-peer network. The published records include a creator record, a presentation record, a file sharing record, a friendly name record, and invitation status record, a capabilities record, and a presence record. Each of the published records has a global unique identifier (GUID) a uniquely and universally identifies each of the record types.
