摘要： It is proposed to copy protect data files for transmission by incorporating DSV data patterns, that is, data patterns which are difficult to encode without causing DSV problems, in the data files. The data in five audio streams and two video streams is placed, by way of encoders (10) and a multiplexer (12) into a stream of blocks of encoded data in the MPEG file format (14). In this format, blocks of video data V are arranged alternately with blocks of audio data A and padding stream blocks P. DSV data patterns (16) are incorporated into the MPEG file (14) by way of an encoder (18) to produce the copy protected data file (15). The DSV data patterns (16) are incorporated into locations within the MPEG file which have no data content such as padding stream blocks P and/or into unused audio data blocks A. The DSV data patterns incorporated within the data blocks fed either to a monitor or to a reproduction system will not interfere with the reproduction such that unfettered access is provided to the transmitted information. However, a CD or DVD writer will generally be caused to write a disc which, when read, will result in a reader returning corrupted data or information signalling a read error. Thus, the data in the MPEG file (14) has been copy protected.

摘要： The present invention relates to a method of copy protecting optical discs, such as CD-ROMs. Instead of encoding data onto the CD-ROMs in a manner which ensures balanced dc content, for copy protection the digital data is encoded and recorded onto the optical disc such that it is arranged to give some of the recorded digital data unbalanced dc content. Thus, for example, the DSV value of the encoded data may be changed rapidly in less than (100) frames to (Figure 9). For an area of digital data on the optical disc in which the DSV has been caused to rise steeply (Figure 10a), heavy distortions in audio arise (Figure 10c) during an attempt to copy an audio track including the single segment of unbalanced dc content.

摘要： In a system for protecting encoded digital data, for example, on a digital audio compact disc (CD-DA), specific audio samples are altered to cause spikes which are audible as clicks if played. All of the codewords in the encoded data which contain those altered samples are then identified, and data in each codeword is changed such that on decoding, the codewords will be identified as uncorrectable. Thus, if the decoded data is played by an audio player, error flags are reliably set so that error concealment, such as interpolation, is invoked and the spikes are inaudible. However, a data reader will either pass the uncorrectable data unchanged or will attempt to correct it. Therefore if a copy of the audio data is made, the clicks will be audible on playback.
摘要翻译：在用于保护编码的数字数据的系统中，例如在数字音频光盘（CD-DA）上，特定的音频样本被改变以引起如果播放时作为点击听起来的尖峰。然后识别包含那些改变的样本的编码数据中的所有码字，并且改变每个码字中的数据，使得在解码时，码字将被识别为不可校正。因此，如果由音频播放器播放解码的数据，则可靠地设置错误标志，使得诸如插值之类的错误隐藏被调用并且峰值听不见。但是，数据读取器将不通过不可修正的数据，或者尝试更正它。因此，如果制作了音频数据的副本，则播放时的点击次数将是可听见的。

摘要： The method and apparatus of the invention utilise the fact that CDs manufactured from the same master will have distinctive physical characteristics attributable to the physical manufacturing process of the master to distinguish counterfeit CDs from genuine discs. For a genuine disc (4), the relative angular orientation of specified sections (1, 2, 3) of the recorded data are determined and recorded. The relative angular orientation of the same sections (1, 2, 3) of data on a test disc (5) are also determined. Where the relative angular orientations are the same it is concluded that the test disc derives from the same source as the genuine disc and is therefore bona fide. Where there is no correlation, the test disc may be identified as counterfeit. The relative angular orientations, or other physical characteristics of the discs, may be physically measured, or may be calculated from information gained by reading the data on the disc.

摘要： The manufacturing process for a data carrying disc, such as a CD, begins with the production of a master, and in the physical manufacturing process of the master, variations are introduced which give the master distinctive physical characteristics and cause errors in the data. The master is used to form generations of discs, and the physical characteristics of the master are passed on down the generations. A group of discs manufactured from the same source consistently exhibit the physical characteristics of the master, and those physical characteristics are used as a 'fingerprint' for identifying that source. To determine the provenance of a data carrying disc, uncorrected data is read from the disc. Information about errors is extracted from the data read. The error information is then compared with characteristic error information which characterises data carrying discs produced from a well known source to determine whether the data carrying disc has been produced from the known source. The error information extracted is representative of errors arising from the physical manufacturing process.
