A display system includes a conversion apparatus converting video luminance including a luminance value in a first luminance range and a display apparatus connected thereto and displaying the video. The conversion apparatus includes a first acquisition unit, a first luminance converter, a second luminance converter, a quantization converter, and an output unit outputting a third luminance signal to the display apparatus. The display apparatus includes: a second acquisition unit acquiring the third luminance signal and setting information indicating display settings recommended to the display apparatus in display of the video; a display setting unit setting the display apparatus, using the setting information; a third luminance converter converting a third code value indicated by the third luminance signal into a second luminance value compatible with a second luminance range, using the setting information; and a display controller displaying the video on the display apparatus based on the second luminance value.

A conversion method for converting luminance of a video, including a luminance value in a first luminance range, to be displayed on a display apparatus includes: acquiring a first luminance signal indicating a code value obtained by quantization of the luminance value of the video; and converting the code value indicated by the acquired first luminance signal into a second luminance value determined based on a luminance range of the display apparatus, the second luminance value being compatible with a second luminance range with a maximum value smaller than a maximum value of the first luminance range and larger than 100 nit. This provides the conversion method capable of achieving further improvement.

Techniques for virtualizing content are disclosed. Elements comprising source content are virtualized by mapping each to and representing each with a corresponding database object. A specification of the corresponding database objects is provided for rendering the source content instead of any original pixel information of the source content so that a virtualized version of the source content is rendered.

Techniques for delivering virtualized content are disclosed. In some embodiments, elements in source content are mapped to a set of corresponding database objects, and the set of database objects is modified to generate a virtualized version of the source content. A specification of the virtualized version of the source content is provided to an output device in response to a request from the output device for the source content.

Techniques for delivering virtualized content are disclosed. In some embodiments, source content is virtualized by mapping elements in the source content to existing database objects, and a specification of the virtualized version of the source content is provided to an output device in response to a request from the output device for the source content. In some such cases, a format of the source content, a format of the virtualized version of the source content, and a native format in which the virtualized version of the source content is rendered at the output device all comprise different formats.

Techniques for virtualizing content are disclosed. One or more objects comprising source video content are determined. The one or more objects comprising the source video content are virtualized by mapping each to and representing each with a corresponding database object. Data comprising the corresponding database objects is provided for rendering the source video content instead of any original pixel information of the source video content so that a virtualized version of the source video content is rendered.

A system and method for controlling and selecting sources in a room on a network. The system allows a remote viewer to create a virtual presence within the room by providing the available displays, corresponding to the sources, to the remote viewer. The system includes a standardizing technique for improving the communication and overall switching of data for streaming on a network. The system can include a recording server for performing dual recording of the video files in each of a local database and a remote database. A graphical user interface (GUI) display is provided to guide a local user through a medical procedure in the standardized system.

A method of processing a video includes capturing a first set of video data at a first definition, transmitting the first set of video data at a second definition lower than the first definition wirelessly to a user terminal, receiving a video edit request wirelessly from the user terminal, and finding video corresponding to edited video data described by the video edit request, thereby forming a second set of video data at a third definition. The video edit request is formed from editing the received first set of video data at the second definition at the user terminal.
