The present disclosure relates to systems and methods for transmitting Standard Dynamic Range (SDR) content. The systems and methods may use a modified Electro-Optical Transfer Function (EOTF) curve to convert nonlinear color values of SDR content into optical output values of modified SDR content. The systems and methods may encode the modified SDR content using eight bits while preventing banding. The systems and methods may transmit the encoded data to a client device for presentation on a display.

Efficient electro-optical transfer function (EOTF) curve for standard dynamic range (SDR) content

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.

Real time tone mapping of high dynamic range image data at time of playback on a lower dynamic range display

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.

Game streaming with spatial audio

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.

Positioning a camera video overlay on gameplay video

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.

Broadcast initiation without interruption to active gameplay

Enabling a user interface (UI) for management of a host device from a client device. A connection is established between the host device and the client device via a web portal. The host device and the client device are without a host management software installed thereon. A content window is displayed on the client device in response to the established connection with the host device. A client status display area is displayed on the client device indicating at least a connection status with the host device. A corresponding host status display area is displayed on the host device indicating a connection status with the client device. The displayed client status display area specifically identifies the client device and defines client parameters for receiving messages during management of the host device. The displayed host status display area specifically identifies the host device and defines host parameters for receiving messages during interaction with the client device.

Remote device communication platform user interface

Managing via a web portal a remote device from a source device connected to a communication network. A device ID is assigned to the remote device, and a remote management software for remote management of the remote device is not installed on the source device or the remote device. Based on the assigned device ID, a connection is established with the remote device via the communication network. A first instruction is received from a user for authenticating access to the web portal. The user is authenticated in response to the received first instruction. An online status is established for the authenticated user. A second instruction is received from the authenticated user requesting access to the remote device. The device ID of the remote device is validated. The validated device ID is associated with the authenticated user. A connection is established between the remote device and the web portal.

Remote device communication platform

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.

Remote desktop access

Automatic file replication and scanning for malware in a sharing environment is based on detection of file system changes. Only one client of the multi-client environment needs to include malware protection software for all clients to benefit. A file replication service for each client monitors a shared directory, and synchronizes files across clients at the file system driver level. When a new file appears in the shared directory of a client system, through this driver, the new file automatically gets replicated. A malware protection component operates by monitoring the directory for new or modified files. File replication causes automatic malware scanning on the client that has protection. When the file has been cleaned and re-written to the directory, the replication service senses that the file has changed and replicates the cleaned file to the other clients. Thus, the replication behavior produces a multiparty file scanning and cleansing protection scheme.

Distributed malicious software protection in file sharing environments

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.

Methodology and system for file replication based on a peergroup

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.
