Methods, systems, and apparatus, including computer programs encoded on computer storage media relate to a method for providing multi-point video presentations with live annotations within a communication platform. First, the system receives video feeds depicting imagery of a number of users. The system then determines a boundary about each user in the video feeds, with the boundaries each having an interior portion and an exterior portion. The system provides a media background for the exterior portions, then generates a composite video for each of the feeds. The system then determines that one or more client devices have annotation permissions, and receives one or more annotation inputs corresponding to at least one of the composite videos. Finally, the system updates at least one of the composite videos to additionally depict the annotation inputs within a third layer.

Provided is a terminal. The terminal may include an input and output interface configured to receive a first video capturing a first user, a communication interface configured to transmit the first video or a first sound of the first user to a terminal of a counterpart and receive a second video or second sound, which is obtained by the terminal of the counterpart, through a video call session, a display configured to display the first video and the second video, and a processor configured to detect a specific event during the video call session, determine whether an inappropriate element is included in the first video or the first sound when the specific event is detected, and stop transmitting the first video or the first sound according to a result of the determination.

Provided is a video reception method performed by a video reception apparatus including a display. The video reception method includes: receiving a reception signal multiplexed from video data and audio data; outputting, as first transfer characteristics information, transfer characteristics obtained by demultiplexing the reception signal; outputting, as second transfer characteristics information, transfer characteristics obtained by decoding the video data, the second transfer characteristics information being information for specifying, at frame accuracy, a transfer function corresponding to a luminance dynamic range of the video data; and displaying the video data while controlling a luminance dynamic range of the display at frame accuracy according to the second transfer characteristics information.

A method of processing an image by a device obtaining one or more images including captured images of objects in a target space, generating metadata including information about mapping between the one or more images and a three-dimensional (3D) mesh model used to generate a virtual reality (VR) image of the target space, and transmitting the one or more images and the metadata to a terminal.

A transmitting apparatus including circuitry configured to generate caption data corresponding to content data and having elements defined in Extensible Markup Language (XML), and output the content data and the generated caption data to a reproducing device.

A transmission method in the present disclosure includes; obtaining an image and image signal characteristics information indicating one of an opto-electrical transfer function (OETF) or an electro-optical transfer function (EOTF) as image signal characteristics of the image; and transmitting a signal including the image and the image signal characteristics information. According to the transmission method in the present disclosure, a receiving device that received a high dynamic range (HDR) image and a standard dynamic range (SDR) image transmitted through broadcasting or the like can display these images appropriately.

A display device includes a display for displaying at least one piece of content, a user input interface for receiving a signal from a remote control device, and a controller for controlling operation of the display device. The controller performs control to display a video of first content in an overall area of a first layer of a screen, to display a first on screen display (OSD) window having predetermined first transparency in a first area of a second layer of the screen upon receiving a first OSD window output request signal, and to change the first transparency to predetermined second transparency when a pointer is located in the first area of the second layer of the screen.

A system and method for altering the characteristics of a display based on environmental data is disclosed. Exemplary embodiments provide a light sensor, an environmental processing unit which is adapted to receive electrical signals from the light sensor and generate an environmentally-reactive control signal (S.sub.a), an image signal processor which accepts S.sub.a and an encoded image signal (S.sub.e) and generates a pre-decoding image signal (S.sub.p), and an image signal decoder which accepts Sp and generates a decoded image signal for the display. The environmentally-reactive control signal (S.sub.a) may contain the instantaneous value of the desired display black level S.sub.b. Alternatively or additionally, the environmentally-reactive control signal (S.sub.a) may contain a signal linearity modification value.

Various embodiments set forth systems and techniques for personalizing censorship of digital content. The techniques include generating, based on a user characteristic, a censorship profile associated with a user, wherein the censorship profile identifies a censorship element; determining a censorship feature associated with the censorship element, wherein the censorship feature is to be activated during playback of digital content that includes the censorship element; identifying, based on temporal boundaries data and temporal facet data associated with a digital content item, one or more portions of the digital content item that include at least one element matching the censorship element; and activating the censorship feature during playback of the one or more portions of the digital content item.

A protected graphics module can send its output to a display engine securely. Secure communications with the display can provide a level of confidentiality of content generated by protected graphics modules against software and hardware attacks.
