Abstract
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.
Claims5
A karaoke device for processing digital data reproduced from a recording medium, the digital data including:
- A) at least two types of digital audio data, including:
- 1) a first type of digital audio data being only one kind of audio, and
- 2) a second type of digital audio data being at least two kinds of audio data;
- B) and coding information, including:
- 1) first information indicating a coding mode of the digital audio data on the recording medium, and
- 2) second information, different than said first information, distinguishing the first type of digital audio data from the second type of digital audio data,
- said karaoke device comprising:
- a) a data processor processing the digital data reproduced from the recording medium, said data processor including a system time clock, a memory for storing said first and second types of digital audio data, and an audio presentation part controlling a presentation time of said first or second type of digital audio data based on said system time clock;
- and
- b) controller receiving the second information from the processed digital data, and controlling the data processor to output selectively one of the first or the second type of digital audio data based on the received second information.
The method for processing digital data reproduced from a recording medium for karaoke, the digital data including:
- A) at least two types of digital audio data, including:
- 1) a first type of digital audio data being only one kind of audio, and
- 2) a second type of digital audio data being at least two kinds of audio data;
- B) and coding information, including:
- 1) first information indicating a coding mode of the digital audio data on the recording medium, and
- 2) second information, different than said first information, distinguishing the first type of digital audio data from the second type of digital audio data,
- the steps comprising:
- a) processing the digital data reproduced from the recording medium;
- b) extracting a system time clock from the digital data;
- c) storing said first and second types of digital audio data;
- d) controlling a presentation time of said first or second type of digital audio data based on said system time clock,
- e) receiving the second information from the processed digital data, and
- f) selectively outputting one of the first or the second type of digital audio data based on the received second information.
