Abstract: There are two different methods of embedding supplemental data, e.g. for watermarking into an encoded signal.I. For an encoder, which needs auxiliary information for encoding (=probability information in this special case), the auxiliary information to encode the supplemental data is derived from data used otherwise in the encoding process. The advantage is that the derived auxiliary data does not have to be stored, so that embedding the supplemental data is economical with respect to the total amount of bits used.II. In the encoding process used for super Audio CD, a set of parameters (e.g. filter coefficients) is used by the encoder, whereby these parameters have to be stored, as they are needed for decoding. To embed supplemental data, at least one of the chosen parameters (e.g. the LSB of the first coefficient) is set to a dedicated value in response to the value of the supplemental data to be embedded. The advantage is that the bit rate will not be affected at all.

Abstract: An information carrier includes information arranged according to a recorded format. The information includes format information indicative of parameters of the recording format such as start and stop addresses of user information. The information is recorded according to predefined encoding rules, which correspond to rules of a different recording format that prescribes a predefined location on the information carrier for recording the format information. However the predefined location includes a confusion pattern and the format information is recorded at a second location that is different from the predefined location. A non-compliant player is unable to read or copy the information carrier because the reading is disturbed by the wrong parameters of the recording format. A recorder is arranged for recording the confusion pattern and relocating format information, whereas a player is arranged to retrieve the relocated format information.

Abstract translation: 信息载体包括根据记录格式排列的信息。 信息包括指示诸如用户信息的开始和停止地址的记录格式的参数的格式信息。 根据预定义的编码规则来记录信息，该规则对应于在信息载体上规定用于记录格式信息的预定位置的不同记录格式的规则。 然而，预定位置包括混淆模式，格式信息被记录在与预定位置不同的第二位置处。 由于阅读受到记录格式的错误参数的干扰，不符合规定的播放器无法读取或复制信息载体。 记录器被配置用于记录混淆模式和重定位格式信息，而播放器被安排用于检索重新定位的格式信息。

Abstract: User information is encoded on a record carrier in accordance with a first record carrier standard, the encoding of the user information also being in accordance with a second record carrier standard. Also, format information is provided on the record carrier for presenting the user information in a predetermined manner, at least a portion of the format information being according to the second standard and not in accordance with the first standard so that a player in accordance with the first standard and not in accordance with the second standard can not play the user information in the predefined manner.

Abstract: In an information delivery system, a security device (SD) manages an access to information (INF). The security device (SD) is capable of providing a pointer (PO) which indicates a location (LO) from which additional data (ADA) may be obtained. The additional data (ADA) may be a description of the information (INF) which is offered. For example, in a pay TV system, the information (INF) may be a particular movie of which the description is “James Bond, Dr. No, action category, 12 year and older, broadcast April 19, at 20H30.” In that case, the pointer (PO) may be used to inform a subscriber that his security device (SD) allows him to watch this particular movie. However, the additional data (ADA) contained in the location (LO) indicated by the pointer (PO), may also be software for various purposes such as, for example, playing games or configuring a receiver (REC) which co-operates with the security device (SD).

Abstract: Supplemental data is embedded in an information signal such as a sigma-delta modulated audio signal. The encoded signal includes two or more channels, e.g. a left channel bit stream and a right channel bit stream. The same supplemental data is accommodated at corresponding predetermined bit positions, e.g. every Mth bit position, of the bit streams. This allows detection and extraction of the supplemental data without the need for accommodating a sync pattern in the signal. At the receiving end, a sequence of Mth bits from the first channel is compared with a corresponding sequence of Mth bits from the second channel. If they are identical, the sequence is a candidate supplemental data sequence. This is done for different sequence positions until the supplemental data has been found.
