    摘要: A digital signal recording disc has a first area and a second area. The second area differs from the first area. The first area stores a first-channel digital audio signal and a second-channel digital audio signal. The first-channel digital audio signal results from quantizing a first-channel analog audio signal with a first quantization bit number. The second-channel digital audio signal results from quantizing a second-channel analog audio signal with a second quantization bit number. The second area stores information of the first and second quantization bit numbers.

    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: 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: An input signal is quantized into a quantization-resultant signal. The quantization-resultant signal is compressed into a compression-resultant signal. The compression-resultant signal is formatted into a formatting-resultant signal corresponding to a predetermined format for a digital recording disc. The formatting-resultant signal includes segments corresponding to user data areas prescribed in the predetermined format. The compression-resultant signal is placed in the segments of the formatting-resultant signal. The formatting-resultant signal is encoded into an encoding-resultant signal of a CD format. The encoding-resultant signal is recorded on a recording medium.
