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:
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.

A digital audio signal obtained from an analog audio signal indicating a music, pieces of audio reproduction control information respectively indicating the adjustment of a sound quality of the music are added to the digital audio signal, and the digital audio signal is recorded with the pieces of audio reproduction control information as packed data. When a user selects a piece of particular audio reproduction control information from the pieces of audio reproduction control information after the packed data is read out, levels of pieces of audio data of the digital audio signal are adjusted according to the particular audio reproduction control information, so that the user can entertain the music at a desired sound quality.

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.
摘要:
An audio signal encoder is provided which is designed to A/D-convert an analog input signal at a first sampling frequency without being compressed and at a second sampling frequency that is two or four times higher than the first sampling frequency in data compression for minimizing data compression-caused errors in high-frequency components encoded. A decoder decoding digital signals produced by the encoder and a record carrier storing therein the digital signals are also provided.
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.

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.
