    摘要: An audio signal encoding apparatus includes a device for compressing multiple-channel digital audio signals into compression-resultant multiple-channel signals respectively. The multiple-channel digital audio signals relate to a sampling frequency and a quantization bit number. The compression-resultant multiple-channel signals, a signal representative of the sampling frequency, and a signal representative of the quantization bit number are formatted into a formatting-resultant signal. The formatting-resultant signal contains a sub packet and a sync information portion. The sub packet contains at least portions of the compression-resultant multiple-channel signals. The sync information portion contains the signal representative of the sampling frequency and the signal representative of the quantization bit number.

    摘要: DVD-video data and DVD-audio data are recorded in a DVD-Avd disc. The DVD-audio data is composed of an audio manager having an audio manager information, an audio manager menu, a first audio title set including first audio data and a second audio title set including second audio data. The first audio data of the first audio title set is connected with audio contents included in the DVD-video data, and a real time information (RTI). pack or a still picture (SPCT) pack is included in the second audio title set. Therefore, the audio contents of the DVD-video data and the audio data of the DVD-audio data are managed by the audio manager information, and text information indicated by real time information or a still picture is displayed while reproducing the audio data. Also, DVD-video data recorded in a DVD-video disc, which is normally reproduced by using a reproducing apparatus dedicated to the DVD-video disc, can be reproduced by using a reproducing apparatus for the DVD-Avd 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: 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. Therefore, when the audio data is read out from the DVD-Audio disc, the audio data can be easily played back from the top position of the musical composition according to the TOC information.
