The techniques described herein relate to methods, apparatus, and computer readable media configured to access multimedia data comprising a hierarchical track structure with a first track of a first sequence of temporally-related media units at a first level, and a second track at a second level comprising metadata specifying a temporal track derivation operation. The metadata includes a set of one or more operations to perform on the first track, each operation including a unit duration of the first sequence and a start unit in the first sequence. The temporal track derivation operation is performed on a set of media units comprising at least the first sequence, and includes applying the set of one or more operations to temporally modify the first sequence to generate second media data for the second track that includes a second sequence of temporally-related media units from the set of media units.

A method for performing an operation of a memory arrangement, comprising receiving a command at a layer of a computer system, determining if the command received is one of a first command type or a second command type, determining a type of command that is able to be received and is capable of operation of the memory arrangement, comparing the type of command capable of operation of the memory arrangement and the received command at the layer, and converting the command received at the layer to a command type capable of operation of the memory arrangement when the type of command received at the layer is different than type of command that is able to be received and is capable of operation of the memory arrangement.

A recording medium includes a video stream of a standard-luminance range and a video stream of high-luminance range, which are used selectively in accordance with a playback environment. The recording medium also includes a subtitle stream of the standard-luminance range and a subtitle stream of the high-luminance range, which are used selectively in accordance with the playback environment. A playlist file includes a management region where playback control information relating to a main stream is stored, and includes an extended region. The management region stores first playback control information specifying playing of the video stream of the high-luminance range and the subtitle stream of the high-luminance range in combination. The extended region stores second playback control information specifying playing of the video stream of the standard-luminance range and the subtitle stream of the standard-luminance range in combination.

A receiving apparatus comprises a recorder of the received digital contents and commercial messages. Commercial message retrieved from the recorder is interposed into a digital content or between a pair of digital contents in accordance with the type of commercial message. Interposition of commercial message is controlled by internal information, such as history of actually displaying the same commercial message, or history of skipping the same commercial message. The receiving apparatus controls the repetition time of displaying the same commercial message, or decision whether or not actually displaying a specific commercial message, or the order of displaying commercial messages. Skip of commercial message is prevented unless display has been repeated over a minimum requirement, or user agrees with a compensation for the skip. Repetition of the same commercial message ceases with skip repeated over a limit. Notice of interposing commercial message or of compensation for skip is made in advance.

The problem to be solved is to make it possible to download via a network, efficiently manage, retrieve, and reproduce an external content associated with a content recorded on a recording medium. To solve the problem, a program is used which controls reproduction of information located on a recording medium and related information. The program includes the steps of: obtaining from the outside specific information associated with predetermined information recorded on a recording medium; and obtaining medium identification information located on a recording medium; wherein if the specific information has been obtained, a storage unit in a reproducing apparatus is controlled to associate the specific information with the medium identification information for storage.

Methods and systems that facilitate the downloading of media items to a first network device from a second network device are disclosed. A plurality of media items are identified Media item metadata associated with the plurality of media items is obtained from the second network device and stored on the first network device. Media item content data associate with a first subset of the plurality of media items is obtained from the second network device and stored on the first network device. In this manner, only media item metadata associate with a second subset of the plurality of media items is stored on the first network device.

An image processing apparatus comprises a receiver (201) for receiving an image signal which comprises at least an encoded image and a target display reference. The target display reference is indicative of a dynamic range of a target display for which the encoded image is encoded. A dynamic range processor (203) generates an output image by applying a dynamic range transform to the encoded image in response to the target display reference. An output (205) then outputs an output image signal comprising the output image, e.g. to a suitable display. The dynamic range transform may furthermore be performed in response to a display dynamic range indication received from a display. The invention may be used to generate an improved High Dynamic Range (HDR) image from e.g. a Low Dynamic Range (LDR) image, or vice versa.

In some implementations, a user can play a music track from a dynamically generated playlist. The user can provide input indicating that the user likes or dislikes the music track and the playlist can be adjusted based on the user input. In some implementations, information can be presented to the user so that the user can preview changes to the playlist before the changes are made to the playlist. In some implementations, a user can adjust playlist criteria (configuration) by adjusting specific music characteristics. In some implementations, a user can adjust playlist criteria by manipulating a list of representative music tracks. In some implementations, a user can compare the user's playlist to playlists of other users.

The present technology relates to a display device that enables content having a wide dynamic range of brightness to be displayed with an appropriate brightness from a reproduction device. The display comprises circuitry configured to store display information related to high dynamic range (HDR) video and to transmit to the reproduction device an extended display identification data that includes display information representing a performance of the display device. The display device includes a monitor configured to display an image of the HDR video in accordance with brightness designated by HDR information if the monitor is capable of displaying the designated brightness and to adjust a brightness of the image of the HDR video to a brightness capability of the monitor if the monitor is not capable of displaying the designated brightness.
