Title:
DIGITAL AUDIO RECORDING MEDIUM AND PLAYER THEREFOR
Document Type and Number:
Japanese Patent JPH03142753
Kind Code:
A
Abstract:
PURPOSE:To efficiently and quickly amplify an output sound by making a sub-code assume the amplifier control command code of the reproducing system of a digital audio signal. CONSTITUTION:The sub-code recorded together with a main code including the digital audio signal is made to assume the amplifier power source control command code of the reproducing system of the digital audio signal. Therefore, the action characteristic of the amplifier of the reproducing system can be controlled according to the control information of an amplifier by decoding the sub-code at the time of reproducing. Thus, since the amplifier is automatically controlled at the time of the reproducing by recording the optimum amplifier control command previously on a disk according to the content of music software, that means, an output level, a high efficient power output is obtained.
