Abstract: The present disclosure relates to a decoding device, a decoding method, an encoding device, and an encoding method, which are capable of enabling a decoding side to accurately recognize a color gamut of an encoding target image. The decoding device includes circuitry configured to receive an encoded stream including encoded data of an image and color primary information indicating a coordinate of at least one color primary of the image. The circuitry extracts the encoded data and the color primary information from the received encoded stream. The circuitry decodes the encoded data to generate the image. Further, the circuitry adjusts a color space of the generated image based on the extracted color primary information. The present disclosure can be applied to, for example, a decoding device of a high efficiency video coding (HEVC) scheme.

Abstract: A liquid crystal display device includes: an acquisition unit that acquires viewing direction information indicating a direction in which a user views a displayed image; a compensation unit that adaptively compensates a chromaticity point in a video signal using the viewing direction information acquired by the acquisition unit together with color shift amount information that uses a color difference to associate the viewing direction with a color shift amount of display light; and a liquid crystal display unit that performs video display based on the video signal compensated by the compensation unit.

Abstract: Video data and audio data of multiplexed data are separated. Abstract video data is generated from the separated video data and abstract audio data is generated from the separated audio data. Then, the abstract video data and the abstract audio data are packed and a packed video and audio data management table is generated from packed video and audio data D2 and video and audio data synchronization information D3. The packed video and audio data management table comprehensively manages the packed video and audio data. Thus, data of various video formats, various audio formats and various multiplexing formats can be monistically managed.

Abstract: A magnetic head accesses sectors of one track in the order starting with a sector where the magnetic head is put into an on-track state. A seek start timing is reliably determined by accessing on a track by track basis with an uncertain process of a read-ahead operation eliminated. A search time is eliminated by accessing any sector within one track. As a result, the number of seeks is minimized and access time is reduced. A sector format is used to perform an access operation on a track by track basis. In this arrangement, each of seek time and search time is reduced during a random access time and a data transmission speed of a disk drive is assured.

Abstract: A stable system is provided wherein the influence of disturbance or the like can be reduced. First error correcting code units and second error correcting code units are used, and thereby a wider range of random errors and burst errors are made correctable to avoid retry operation. Thus, stable data reproduction is carried out without degrading transfer rate. Further, the constitution of error correcting blocks is set so that when a head is moved to some track during seek operation, a sector having the second error correcting code recorded therein is the first sector to be read.

Abstract: In order to reproduce data in a stable manner by correction of random and burst errors of a wide range without lowering a transfer speed, C2 error correction for correcting an inter-sector error is carried out in addition to the conventional C1 error correction for correcting an error generated in a sector. The configuration of an error correction unit (or an ECC block) including C1 and C2 codes is formed as a track. That is to say, one track is used as the base of an ECC block unit. In this way, two ECC block units never exist in the same track.

Abstract: An information storage device which stores information in recording areas generated by dividing a track is provided, wherein servo information is configured, the information storage device including: a recording area setting part which divides a storage medium into predetermined recording areas; an error detecting part which detects an error in the servo information. When the error detecting part detects an error in the servo information, recording areas spanning from a recording area including the servo information having the error to a recording area including next servo information are replaced by other recording areas, wherein the servo error information is managed and recording area setting is restarted.
