    Abstract: An intermediation method used in an intermediation system that includes an intermediation device determining a permission for application services requiring user authentication on a network, where in response to a user request, a first account used for a first service and a second account used for a second service, and a registration request for using the linking service linking the first application service and the second application service are associated with each other, when the two accounts are valid, as accounts usable in a linking service, an association between the first and second services is stored in the intermediation device, and when the user makes a request to use the linked services, that use is controlled by a query to the intermediation device regarding whether the account is associated as able to use the linking service.

    Abstract: A playback method according to one aspect of the present disclosure is performed by a Blu-ray device connected to a display device. The playback method includes obtaining, from a recording medium, output control information of content recorded on the recording medium; obtaining, from the recording medium, a video signal of the content recorded on the recording medium; and (a) outputting the obtained video signal to the display device without converting image quality of the video signal, when the obtained output control information does not restrict output of content using a first copyright protection technology, and (b) converting the image quality of the obtained video signal and outputting the video signal to the display device, when the obtained output control information restricts output of content using the first copyright protection technology and output using the first copyright protection technology is performed according to a type of the display device.

    IPC: H04N5/235

    Abstract: A video display apparatus includes: a tone mapping processor that converts, by using dynamic metadata indicating a maximum luminance of a video in each of a plurality of time intervals included in a predetermined period, a luminance of the video in each time interval based on conversion characteristics according to the maximum luminance of the video in the time interval; and a display. The tone mapping processor switches between: a first operation of performing the tone mapping process by using first dynamic metadata that indicates the maximum luminance that is constant over the plurality of time intervals, the first dynamic metadata being generated by using static metadata that indicates a maximum luminance of the video in the predetermined period; and a second operation of performing the tone mapping process by using second dynamic metadata in which the maximum luminance varies over the plurality of time intervals.
