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.

A method and system for recording and reporting license plate indicia are provided. The method includes receiving an input command from a user of a vehicle requesting a capture of an image of license plate indicia of a second vehicle, capturing, via one or more cameras, one or more image of the license plate of the second vehicle, determining, using the processing circuitry, a license plate number from the captured one or more images of the license plate, and displaying the recognized license plate number on a display of the vehicle. The method further includes detecting a location of the vehicle and storing the determined license plate number, the location of the vehicle, and the image of the license plate indicia in an audio head unit or in a navigation unit.

An exemplary virtual reality system accesses metadata describing a plurality of frame sequences that each include two-dimensional color data frames and depth data frames that depict a different view of a three-dimensional (3D) scene. The virtual reality system identifies a set of experience parameters defining a particular virtual reality experience associated with the 3D scene and that is to be experienced by a user using a media player device. Based on the metadata and the set of experience parameters, the virtual reality system selects frame sequences from the plurality of frame sequences for inclusion in a frame sequence subset that is customized to the particular virtual reality experience and that collectively includes data sufficient to allow the media player device to generate a virtual 3D representation of the 3D scene. The virtual reality system also provides the selected frame sequences of the frame sequence subset to the media player device.

Two or more video signals are received at respective two or more peer-level storage nodes. Discrete wavelet transformations are performed on the two or more video signals via the two or more peer-level storage nodes. Temporally stationary background data is determined from the discrete wavelet transformations at each of the two or more peer-level storage nodes. Redundancies are determined using the temporally stationary background data, the redundancies indicating an overlap between the two or more video signals. A storage size of two or more video signals is reduced by not storing the redundancies on at least one of the peer-level storage nodes.

In some embodiments, a method receives sub-bitstreams from a multi-pass transcoding process of a video. A target quality is received based on a characteristic of transcoding of the video. Then, the method generates a combination of sub-bitstream chunks from the sub-bitstreams for the video. A set of exchange rates is calculated where each exchange rate defines how much bitrate will be reduced in relation to quality if an anchor sub-bitstream chunk from the combination of sub-bitstream chunks is replaced with another sub-bitstream chunk from other sub-bitstreams. Then method iteratively exchanges one of the anchor sub-bitstream chunks in the combination of sub-bitstream chunks with another sub-bitstream chunk based on the exchange rate of the anchor sub-bitstream chunk in the combination of sub-bitstream chunks until the quality measurement of the combination meets the target quality. Then, the combination of sub-bitstream chunks is recorded as a transcoded bitstream.

Systems and methods provide for editing of spherical video data. In one example, a computing device can receive a spherical video (or a video associated with an angular field of view greater than an angular field of view associated with a display screen of the computing device), such as by a built-in spherical video capturing system or acquiring the video data from another device. The computing device can display the spherical video data. While the spherical video data is displayed, the computing device can track the movement of an object (e.g., the computing device, a user, a real or virtual object represented in the spherical video data, etc.) to change the position of the viewport into the spherical video. The computing device can generate a new video from the new positions of the viewport.

A method of processing a video includes capturing a first set of video data at a first definition, transmitting the first set of video data at a second definition lower than the first definition wirelessly to a user terminal, receiving a video edit request wirelessly from the user terminal, and finding video corresponding to edited video data described by the video edit request, thereby forming a second set of video data at a third definition. The video edit request is formed from editing the received first set of video data at the second definition at the user terminal.

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.
