    摘要： A format of data recorded in a DVD-Audio disc is composed of an audio manager (AMG) and a plurality of audio title sets (ATSS) following the AMG. A plurality of audio packs are arranged in each ATS. An audio signal indicating a musical composition is encoded to audio data in a signal processing circuit, and the audio data is arranged in the audio packs. The audio data of the audio packs are formatted in a DVD formatting unit with the AMG to be arranged in the ATSs following the AMG. Also, copyright information is arranged in an area of a control data block placed in a read-in area of the DVD-Audio disc. Table-of-contents (TOC) information indicating a top address of the audio data is automatically produced and is arranged in an empty area of the control data block reserved for the copyright information, in an area of the audio packs, in an area of the AMG or in an area of the ATSs. The AMG, the ATSs including the audio packs and the TOC information arranged at the data format in the DVD formatting unit are transmitted to a human editor through a transmission medium and is recorded in the DVD-Audio disc.

    摘要： In an audio signal encoding apparatus, a first audio signal and a second audio signal are added into an addition-result signal. The first audio signal is subtracted from the second audio signal to generate a subtraction-result signal. A first difference signal is generated which represents a difference in the addition-result signal. A second difference signal is generated which represents a difference in the subtraction-result signal. A plurality of first predictors have different prediction characteristics respectively, and are responsive to the first difference signal for generating first different prediction signals for the first difference signal, respectively. A plurality of first subtracters operate for generating first prediction-error signals representing differences between the first difference signal and the first different prediction signals, respectively. A first minimum prediction-error signal representative of a smallest difference is selected from among the first prediction-error signals. A plurality of second predictors have different prediction characteristics respectively, and are responsive to the second difference signal for generating second different prediction signals for the second difference signal, respectively. A plurality of second subtracters operate for generating second prediction-error signals representing differences between the second difference signal and the second different prediction signals, respectively. A second minimum prediction-error signal representative of a smallest difference is selected from among the second prediction-error signals.

    摘要： At least one musical composition is transmitted via a digital video disc together with bonus information relating to the musical composition and an approved interactive data required when a user accesses the bonus information. An arbitrary interactive data is entered by the user accessing the bonus information. The transmitted musical composition is reproducible regardless of the entered interactive data. However, a reproduction of the bonus information is allowed only when the entered interactive data agrees with the approved interactive data.
