Abstract: A system for facilitating a virtual screening is disclosed. The system identifies a user for participating in a virtual screening of media content. The system generates a unique link for the user to facilitate access to the media content. When the user interacts with the link, the system prompts the user to authenticate with the system and determines whether the authentication was successful. If authentication is successful, the link is associated with an identifier of the user and/or a user device. A request for a key for decrypting the media content and a request for a digitally signed file accessing the media content pursuant to parameters are made. If the digitally signed file is valid, the system applies a watermark to the media content to track the use of the media content and streams the media content to the user. Feedback on the media content is obtained from the user.

Abstract: Aspects of the disclosure provide methods and apparatuses for media processing. In some examples, an apparatus includes processing circuitry. The processing circuitry can exchange, with a server device, a plurality of control messages over a control plane channel that uses a first transport protocol. The plurality of control messages belongs to a control plane of a bidirectional protocol for immersive media distribution. The processing circuitry receives, from the server device, a first plurality of data messages over a first data plane channel that uses a second transport protocol. The first plurality of data messages belongs to a data plane of the bidirectional protocol and carries immersive media content. The processing circuitry presents the immersive media content carried by the first plurality of data messages.

Abstract: One aspect of this disclosure relates a video processing device comprising a processor for processing a manifest file for video streaming for a user. The manifest file comprises at least a plurality of positions defined for a scene that are associated with pre-rendered omnidirectional or volumetric video segments stored on a server system. The manifest file may also contain a plurality of resource locators for retrieving omnidirectional or volumetric video segments from the server system. Each resource locator may be associated with a position defined for the scene. The video processing device may be configured to associate a position of the user with a first position for the scene in the manifest file to retrieve a first omnidirectional or volumetric video segment associated with the first position using a first resource locator from the manifest file.

Abstract: Techniques are provided for processing media content. For example, a process can include using a scene description to obtain media information and buffer information for a media object. The media information can identify an expected format for storing the media object in one or more output buffers of a media pipeline. The buffer information can include output buffer attributes. The process can include using the media information and the buffer information to initialize the media pipeline for the media object. The process can include obtaining the media object in a delivery format and generating one or more processed media objects. Each processed media object can be converted from the delivery format to the expected format for storing the processed media object in an output buffer. The process can include outputting the processed media object(a) to the output buffer(s) using the initialized media pipeline.

Abstract: An automated system/method for identifying and enabling viewer selection/purchase of products or services associated with digital content presented on a display device. Products within the digital content are identified and existing product placement data is ascertained. For products that do not include such data, other methodologies, with the assistance of third-party servers, are employed to assess identity and purchase availability. Viewer input designate products to assess or products can be automatically assessed. Viewers initiate purchase of identified products via the display device or other electronic devices controlled by viewers, such as via viewers' smart phones. Various processes for identifying products include use of AI processing, access to data on third-party servers, crowd sourcing and other methodologies. Various techniques for selecting products for purchases are employed including employing 3D codes (e.g., QR codes) alongside presented products to enable other portable electronic devices to facilitate purchase. Digital representations of the selected products (i.e., of real- world products) may be purchased or licensed for use within the digital realm. Other features are described.
