Several ways are provided for a viewer of a movie to create a deep tag, that is, a bookmark for a segment of the movie. The deep tag can be associated with descriptive text and sent to an address provided by the viewer, either an e-mail address or an instant messaging address. Additionally, before the deep tag is created, it can be checked whether the content owner of the movie is known. If known, the content owner's rules, if any, regarding deep tagging are followed. If unknown, a set of registered content owners can be alerted of the presence of new content. When ownership of the new content is established, the already-created deep tags can be updated in accordance with the content owner's rules, if any, regarding deep tagging.

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 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.

A playback device reads out from a recording medium and plays multiple High Dynamic Range (HDR) video streams that are encoded with video information. The playback device includes a first register, a second register and a playback unit. For each of the HDR video streams, the first register stores first information indicating whether the playback device corresponds to or not, and the second register stores second information indicating whether a display device connected to the playback device corresponds to or not. The playback unit plays the HDR video streams using a playback format selected based on a playback program stored in the recording medium, in a case where the first information and the second information indicate that there are multiple playback formats corresponding to both the playback device and the display device.

In order to provide a recording and reproducing device that allows a user to select and manage arbitrary play lists, a unit of management for managing all registered play list information and an upper management hierarchical level are added. The unit of management is adapted to be handled on the same level with unified information that indicates a reproduction range of all AV data. User-defined unified information is adapted to be handled on the added management hierarchical level. The user-defined unified information is formed to allow arbitrary reproduction ranges contained on a lower hierarchical level to be registered.
