Abstract
Abstract The disc contains a synchronising signal, a digital audio data and a subcode signal recorded in each frame. At the predetermined bits (user's bits) of the subcode signal, the codes that correspond to a hue parameter, an intensity parameter and a fade-in or a fade-out parameter are recorded.
