Description

408304 V. Description of the invention u) The present invention relates to an audio disc, a method and a device for playing audio data recorded thereon, and more specifically, this case is related to a disc of high-quality audio data And method and method for playing audio data recorded on it. Generally speaking, 'audio data recorded on a compact disc (CD) is sampled at 44.1 KHz' and each sample is quantized into 16-bit audio data "compared to a phonograph record (LP). CDs are more convenient to use and store, but at the same time their sound quality is inferior. For example, when sampled at 44, 1 KHz and quantized to 16 bits; the original sound is difficult to reproduce when the audio data is played, and this difference can be discerned when compared to earlier records than CDs. In fact, the human audible audio range is greater than 20KHz, and the dynamic range should be 120dB. With CDs, it is impossible to record or play multi-channel music that has become more and more important, because it can only record audio signals of up to two channels. In response to the above problems, a variety of uses have been made to increase the sampling frequency and recording channels of audio data. Several methods have been proposed to improve the sound quality of playback. Currently, a disc player for playing various discs has been designed. These discs include digital versatile disks (DVJ). In DVD discs, video and audio data is stored in a high-density manner, and video data is recorded in MPEG format. Audio data is recorded with linear pulse code modulation (pCM), Dolby AC_3, or ^^ ". The device used to play DVD video discs has a form of playing video / audio data for reproduction in DVD video Video / audio data on the disc.
