Problems solved by technology

[0007] However, the use of such redefined data is completely detrimental to the above-mentioned convenient identification of recording start Ids and track numbers on the recording medium when the data is recorded on a known digital recording device by means of a digital interface.
[0008] In particular, with this reproducing apparatus applicable to digital audio discs conforming to the new standard as well as existing CDs, there is a confusion that the above-mentioned convenience can be utilized when reproducing a CD, and when reproducing a CD The above-mentioned convenience cannot be used when opening a new disk, so it is very inconvenient from the user's point of view

Embodiment Construction

[0063] Now, the present invention will be described by referring to the accompanying drawings that can illustrate preferred embodiments of the reproducing apparatus and reproducing method according to the present invention.

[0064] Embodiments of the reproducing apparatus according to the invention as described below are suitable for reproducing music from compact discs (CDs) and from novel discs capable of storing high-speed 1-bit digital audio signals and can also output audio files conforming to the Digital Audio Interface standard. audio signal. This new type of optical disc capable of storing high-speed 1-bit digital audio signals will be referred to as an HD (High Definition) disc hereinafter.

[0065] Each high-speed 1-bit audio signal recorded on the HD disc can be obtained by delta-sigma (ΔΣ) modulation of an analog audio signal, and the audio signal also has a data format of 1-bit data word length and 2,8224MHz ( 44.1KHz×64) sampling frequency.

[0066] Fig. 1 is ...

Abstract

This invention relates to a reproduction method and also to a reproduction apparatus adapted to transmit a first digital signal for main data of a piece of music and additional data accompanying the main data and including the number of the piece of music and the elapsed time on the track and a second digital signal for main data of the piece of music and accompanying absolute time data on a common digital interface.

Description

technical field [0001] The present invention relates to a reproduction method and also to a reproduction device adapted to transmit main data for a piece of music and additional data accompanying the main data comprising the number of this piece of music and the elapsed time on the track and a second digital signal for the master data of the piece of music and the accompanying absolute time data on a common digital interface. Background technique [0002] The digital audio interface output of known laser disk (CD) is used to produce the channel state data that comprises the type code that is used to identify the type code of the CD type of the CD disc to be played except the main data that all is digital audio data and comprises Q code. User data, where each Q-code includes a track number and the elapsed time of a piece of music on the track. [0003] In addition, for great user convenience, many known recording devices using a digital audio tape (DAT) or a minidisc (MD) as...
