摘要:
A method for processing an analog video signal that represents a work for which rights information is asserted. The signal includes a rights assertion mark (RAM) in the video portion of the signal within the visible picture such that capture of the picture will include the mark. The signal also includes copy control information (CCI) bits in the vertical blanking interval of the signal for representing copying and redistribution rules. If the RAM is present and the CCI bits are present, then the copying and redistribution rules represented by the CCI bits are applied. If the RAM is present but the CCI bits are not, then the most restrictive copying and redistribution rules that can be represented by the CCI bits are applied.

An apparatus for processing data and content includes at least one drive and a player (that may be implemented by software). At least some of the content is protected using a content scrambling scheme such as audio or video watermarking. The drive and player cooperate to operate in a lockable mode wherein if protected content is provided to the drive, the drive and player are interlocked so that the content is presented by the player only in accordance with consistent with protection scheme being used, and cannot be presented by any other player. Moreover, in the locked mode, protected content may not be accepted from any other drive. The drive and player are switched to an unlockded mode by presenting to the drive unprotected content.

VEIL modulation is a method of “subliminal” encoding of data in a video image that is similar to a watermark. The encoding consists of alternately proportionately raised and lowered luminance on selected horizontal scan lines. The encoding can be detected using a notch filter centered at half the line frequency. The encoding is lost, however, if the resolution of the video signal is changed downward. The invention preserves the encoding by coding alternate groups of lines, not alternate lines. This allows detection with a notch filter even after a reduction in resolution.

An optical disc used for storing content includes a theft control area selected to render the disc unreadable. The disc must be exposed to radiation of a specific wavelength before it can be read by a regular device. The theft control area may include an area that contains data that instructs the device not to read the disc. This area includes a coating that changes its optical characteristics when exposed to the radiation. The material could be radiochromic or thermochromic. Alternatively, the theft control area includes an RFID device that includes an element that is radiation sensitive. In this embodiment, when the disc is irradiated, the element changes its electrical characteristics.

Images may be registered using temporal (time-based) and spatial information. In a film implementation, because film is a sequence of frames, using information from neighboring frames may enable a temporally smoother visual experience. In addition, it may be beneficial to take advantage of the fact that consecutive frames are often shifted similarly during the photographic process. Distortion measures may be used that discount candidate transformations that are considered to be too far from one or more preferred transformations, such as, for example, an optimal transformation from another frame or block or a currently-optimal transformation from the same frame/block. Composite color images may be processed to provide registration of underlying components.

A double-sided optical disc, such as a DVD-18 disc, is formed with data tracks on each layer. The tracks on one side are oriented along one spiral while the tracks on the other side are oriented along a second spiral, the two spirals being oriented in opposite directions as viewed from the respective sides. A player with two laser read heads is provided for reading the disc. Each laser read head is disposed adjacent to a respective disc side. The data is read from the two sides, either in sequence from one side and then the other, simultaneously, or in some alternating fashion.
摘要:
A system for playing a selected one of multiple audio tracks recorded in synchronized fashion with a motion picture on an optical disk. The optical disk has encoded on it a mixing master music and effects (“M&E”) track, or a switching master M&E track. Individual audio tracks are provided for language-specific versions of the same motion picture, but these tracks have data recorded in them only where there is dialog. In this way, for many a motion picture, all tracks but masters will have data recorded for well less than half of the running time of the motion picture. When a mixing master is used, it is mixed with a language-specific track when the latter has dialog; the mixing master contains no dialog. If a switching master is used, it may contain dialog recorded with the M&E; when a language-specific track has dialog recorded in it, it also contains M&E and the track is played to the exclusion of the switching master.
