This invention relates to a karaoke CD format and a device for controlling audio signals utilizing the karaoke CD format which provides a user with selective reproduction of the voice of a player. The karaoke CD format includes a CD format divided into video sectors and audio sectors. The audio sectors are further divided into a part for recording accompaniment sound and playing sound at the same time and a part for recording accompaniment sound only. There is provided record coding information for distinguishing the parts. An apparatus, method and storage medium for reproducing digital data, are discussed. According to an embodiment, the apparatus includes an audio data processor to receive data units of digital audio data, the data units corresponding to at least one of: 1) a first type of digital audio data, and 2) a second type of digital audio data which includes at least one content different from the first type of digital audio data; each type of digital audio data being specified by attribute information, which has: a) first information for indicating a coding mode of the digital audio data, and b) second information, different than the first information, for identifying one of the first type of digital audio data and the second type of digital audio data.
摘要:
A digital data file encryption system and method where digital data encrypted to a high level and an encryption key are received and stored in a computer. The stored, encrypted digital data is decrypted on the basis of the encryption key and stored in a buffer of a predetermined size. Output digital data from the buffer is reencrypted to a low level of encryption and downloaded to a digital data playing device or a data storage medium. Therefore, a digital audio or video data file is prevented from being diverted in unencrypted form from a computer communication network when it is transmitted to a personal computer through the computer communication network and, in turn, downloaded to the digital data playing device. Further, the digital data playing device is prevented from rising in cost due to the use of simple encryption for data downloaded to the playing device.
