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.

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.

A system and method for controlling media devices over telecommunication networks is disclosed. In particular embodiments, the system and method utilize cellular telecommunication networks. The present system and method allows a user to control and, in some instances, unify a multitude of devices over the telecommunication network. Through telecommunication networks, such as cellular networks, media and entertainment can be shared between multiple devices.

A method of placing an ad in a video in an original format may include producing a transcoded video in a proxy format which is a representation of frames of the video in the original format. The transcoded video in the proxy format is convertible to other formats for output. The method may include selecting the ad from a set of ads, selecting a location within a frame of the transcoded video where the ad is to be placed, selecting frames of the transcoded video where the ad is to be placed, placing a placeholder in the transcoded video in the selected frames at the selected location, and storing the transcoded video in the proxy format. When the transcoded video is presented to a user on a display device, the selected ad is inserted in place of the placeholder.

There is provided an information processing apparatus, an information processing method, a recording medium, a playback apparatus, a playback method, and a program that are designed to prevent an unnatural change in luminance during random access. The information processing apparatus according to one aspect of the present technology generates dynamic metadata including information regarding luminance of a picture, and encodes HDR video data such that the dynamic metadata is added to each picture serving as a random access point. For example, the dynamic metadata can be allowed to be added to the first picture of a GOP, the first picture serving as the random access point during fast-forward playback/rewind playback or cueing playback. The present technology can be applied to a Blu-ray (registered trademark) Disc player.

Systems and methods for media storage and retrieval. In one embodiment, a system may include a controller to receive first commands from a remote control, transmit second commands to a mass storage device, receive first signals corresponding to data from the mass storage device, and transmit second signals corresponding to the first signals to a display device or audio device configured to receive the second signals and reproduce the data for observation by a user. The mass storage device may include a mechanism to store, retrieve, and play one or more discs containing the data, and it may be configured to transmit the data to the controller using the first signals. Methods for media storage and retrieval are also disclosed herein.

A configuration is realized in which a packet delimiter can be discriminated from an MMTP packet string including MMT format data, and a packet can be selectively acquired and reproduced. The MMT format data is input through a broadcast wave or the like, a packet length of an MMT protocol (MMTP) packet including the MMT format data is acquired, and recording data in which an additional header storing the acquired packet length is set before the MMTP packet, is generated, and is recorded in an information recording medium. A reproducing device is capable of discriminating a delimiter of each MMTP packet, according to the packet length of the MMTP packet, read from the additional header, is capable of acquiring reproducing data, for example, image data, from the selected packet, and is capable of decoding and reproducing the acquired data.

A method of placing an ad in a video in an original format may include producing a transcoded video in a proxy format which is a representation of frames of the video in the original format. The transcoded video in the proxy format is convertible to other formats for output. The method may include selecting the ad from a set of ads, selecting a location within a frame of the transcoded video where the ad is to be placed, selecting frames of the transcoded video where the ad is to be placed, placing a placeholder in the transcoded video in the selected frames at the selected location, and storing the transcoded video in the proxy format. When the transcoded video is presented to a user on a display device, the selected ad is inserted in place of the placeholder.

A digital content package includes first content comprising a video feature such as a motion picture or the like, and a user-selectable application configured to operate as follows. When activated using an icon off of a menu screen, the application records an identifier for scenes (discrete portions) of the first content that are selected by a user to generate a playlist. The user may select the scenes by indicating a start and end of each scene. The application saves the playlist locally, then uploads to a server. Via a user account at the server, a user may publish the playlist to a user-created distribution list, webpage, or other electronic publication, and modify the playlist by deleting or reordering scenes.

A network editor comprises a central location with stored videos such as movies that can be edited by editors at remote locations. An editor receives a representation of a video and specifies edits relative to the representation, enabling the editor to use a device lacking sufficient processing capability to edit the video directly, and also reducing the volume of information transmitted between the central location and the remote editor. The central location is able to provide the edited movie in a format suitable to the display capabilities of the viewing device of the viewer requesting the edited video.
