摘要:
An amount-of-movement detection device which is capable of detecting the amount of movement with a high degree of accuracy when the amount of movement of an image is detected by hierarchical block matching method. An amount-of-movement detection device 1 forms image data S2.sub.n and S3.sub.n of plural hierarchies having different resolutions from each other, by input image S1.sub.n input at a first point in time, and forms multiplexed image data S2.sub.n-1 and S3.sub.n-1 of a higher hierarchy of low resolution, based on an input image S1.sub.n-1 input at a second point in time, by selecting pixels overlapping with each other from the image data of the lower hierarchy having higher resolution and reducing them in size, in order to detect a motion vector by block matching at a predetermined block unit for each of the hierarchies corresponding to the hierarchized image data S2.sub.n and S3.sub.n and the multiplexed and hierarchized image data S2.sub.n-1 and S3.sub.n-1. Thus, the accuracy in the detection of an amount of movement can be greatly enhanced.

摘要:
A recording apparatus according to the present invention comprises converting means 15, 18, and 19 and recording means 23, 24, 32, and 33. The converting means 15, 18, and 19 convert the data structure of data into a file structure handled by software. The recording means 23, 24, 32, and 33 record data on a record medium. The file structure has a first data unit as entity data, a second data unit as a set of a plurality of first data units, and a data portion describing management information for managing the relation of the plurality of first data units and attributes of entity data of the first data units. The data portion contains security information for protecting intangible property rights of data.
摘要:
A digital recording apparatus using a disc shaped record medium including an extracting unit that extracts outlined information of each of a plurality of files recorded on the disc shaped record medium. A correlating unit correlates the extracted outlined information and the plurality of files and generates an index file. A recording unit records the index file to a predetermined position of the disc shaped record medium. When a predetermined operation mode is performed, a plurality of types of data of the plurality of files are output in a predetermined format.

There are disclosed methods and systems (and related data structures) for processing metadata in files, including media files, so that an alteration or falsification of the metadata can be detected. According to certain embodiments, the metadata includes hash values and digital signatures that were generated by a content server. These hash values and digital signatures can be used by a client device to authenticate the metadata.

MAC values formed with respect to each file belonging to a directory 122A and ICVs (D-ICVc) formed on the basis of the MAC values of all files belonging to the directory 122A are stored into a sequence page 121A. Sequence pages 121A, 121B, formed respectively with respect to all of directories 122A, 122B, on a disk and the ICVs formed on the basis of the D-ICVs stored in all of the sequence pages 121A, 121B, . . . are stored into a sequence block 114. Since the MAC values are closed and managed every directory by the sequence pages 121A, 121B, . . . , a data alteration check can be executed every directory. An alteration check of data recorded on a recording medium can be efficiently performed.
