A decoding system decodes a video stream, which is encoded video information. The decoding system includes an attribute information acquirer that acquires first attribute information, indicating whether a dynamic range of luminance of the video stream is a first dynamic range or a second dynamic range that is wider than the first dynamic range, and a decoder that acquires the video steam and generates decoded video information. The decoding system also includes an outputter that, in a case where the first attribute information indicates the second dynamic range, outputs the decoded video information and maximum luminance information indicating a maximum luminance of the video stream in accordance with the second dynamic range. Further, in other cases, the outputter outputs the decoded video information and maximum luminance information indicating the maximum luminance of all pictures in the video stream.

A decoding system decodes a video stream, which is encoded video information. The decoding system includes a decoder that acquires the video steam and generates decoded video information, a maximum luminance information acquirer that acquires maximum luminance information indicating the maximum luminance of the video stream from the video stream, and an outputter that outputs the decoded video information along with the maximum luminance information. In in a case where the video stream includes a base video stream and an enhanced video stream, the decoder generates base video information by decoding the base video stream, an enhanced video information by decoding the enhanced video stream, and generates the decoded video information based on the base video information and the enhanced video information, and the outputter outputs the decoded video information, along with the maximum luminance information.

A decoding method of a video stream, which is encoded video information. The video stream includes a base video stream, and an enhanced video stream, which is a video stream to enhance luminance of the base video stream, and a describer that contains the combination information of the base video stream and the enhanced video stream. The decoding method includes acquiring the describer, and identifying the combination of the base video steam and the enhanced video stream. The decoding method also includes generating base video information by decoding the base video stream, generating enhanced video information by decoding the enhanced video stream, generating decoded video information based on the base video stream and the enhanced video stream, and outputting the decoded video information.

The present technology relates to a reproduction device, a reproduction method, and a recording medium that enable content having a wide dynamic range of brightness to be displayed with an appropriate brightness. A recording medium, on which the reproduction device of one aspect of the present technology performs reproduction, records coded data of an extended video that is a video having a second brightness range that is wider than a first brightness range, brightness characteristic information that represents a brightness characteristic of the extended video, and brightness conversion definition information used when performing a brightness conversion of the extended video to a standard video that is a video having the first brightness range. The reproduction device decodes the coded data and converts the extended video obtained by decoding the coded data to the standard video on the basis of the brightness conversion definition information.

There is provided a reproduction apparatus, a reproduction method, a program, and a recording medium that can prevent an unnatural change in luminance in a case where other information is displayed by being superimposed on a video. A reproduction apparatus according to an aspect of the present technology receives a video stream to which dynamic metadata including luminance information of a picture has been added, and in a case where predetermined information is superimposed and displayed on the picture, adds metadata indicated by a flag indicating the metadata used for luminance adjustment while the predetermined information is superimposed and displayed to the picture constituting the received video stream, and outputs the picture to which the metadata has been added to a display apparatus. The present technology can be applied to a Blu-ray (registered trademark) Disc player.

The present embodiments provide methods and systems to playback and customize the playback of content relative to the portable storage medium. Some of these methods identify content to be rendered, through a playback device, in association with a first portable storage medium; identify one or more customizable display parameters to be applied in displaying the identified content; receive a first definition, following the identification of the customizable display parameters, for at least a first customizable display parameter of the one or more customizable display parameters; and cause the first definition for the first customizable display parameter to be stored on the playback device in association with the first customizable display parameter such that the first definition is to be applied by the playback device in rendering the content relative to the first customizable display parameter.

A playback device reads out and plays contents from a recording medium. The playback device includes a first decoder that decodes a base video stream and an enhanced video stream, a second decoder that decodes encoded graphics data, and a first superimposer that superimposes the enhanced video information and stores enhanced high-luminance video information in a first video plain. The playback device also includes a first processor that converts color of a number of levels into a converted number of levels, a second superimposer that superimposes the decoded graphic data on the enhanced high-luminance video information, a second video plain storing the video information, and a second processor that converts color of a number of levels into a converted number of levels. The playback device further includes a third superimposer that superimposes the decoded graphic data on the high-luminance video information, and an outputter that outputs the superimposed result.

The reproduction device outputs data of the extended video after adding frame information including the brightness characteristic information to frame data when information acquired from a display device that is to be an output destination of the video includes information representing a display performance of the extended video, and when no information representing the display performance of the extended video is included, outputs the data of the standard video. The present technology can be applied to a player that reproduces content.

Disclosed herein is a system and method for rendering media related content and web services. According to one or more embodiments, media content is rendered from a source. In one or more segments of the media source, at least one of an object, person or location is identified and additional information, relevant content or services about the person, object or location are displayed or made accessible while or after the media content is being rendered, on one or more devices and/or on one or more paired devices.
