    摘要: In record or content control management systems, various selected reference, record control, copy protection or control information signals, or other signifiers, are used to identify control signals, for example, bits, to provide control of subsequent use of data, audio and video signals in the analog and digital domain. Method and apparatus are disclosed for modifying the effects of a content control system as well as for modifying an effect of a copy protection signal. To this end, the reference, record control, copy protection signals, or other control information signals, e.g., content control signals, may be modified to cause an erroneous or unintended reading subsequently of the reference or control signals which in turn correspondingly alters the control command of the record or content control system. Further, where a copy protection signal is being used as a control signal, a modification may be made to the copy protection signal to alter the subsequently generated control command while still maintaining copy protection effects in the analog domain and allowing recording in the digital domain. Also, included are unique methods for providing content control.

    摘要: Subversive DSV (SDSV) sequences of data symbols having a large absolute value of DSV are extremely valuable in the copy protection of optical discs as they can induce uncorrectable read errors. However, very few SDSV sequences of data symbols can be found in multimodal codes such as Eight-to-Sixteen Modulation (ESM) utilised in DVDs. It is required to select data symbols, for encoding using a multimodal code, which are capable of forcing an encoder to produce at least one subversive sequence of code words. A possible code word for a data symbol is selected if the code word has a large absolute value of DSV and there are no alternative code words, or all alternative code words are equivalent, or all alternatives except one are ruled out by RLL rules.

    摘要: A computer network having a requesting node and a providing node permits data transfer therebetween when permitted by an authorizing node. Reports generated in response to authorizations and reports generated in response to data transfers are reconciled at a reconciliation node to improve the accuracy of payments collected and paid for use of the data. Such payments include copyright royalties for audio, video, and other works recorded in digital format.
