Abstract
A multimedia platform records a performance on a keyboard synchronously with a picture by periodically regulating an internal clock, which is indicative of the lapse of time, with time codes inserted into the set of video data codes representative of the picture, and reproduces the performance through an automatic player piano also synchronously with the picture by periodically regulating the internal clock with the time codes, whereby the user enjoys himself or herself in the performance as if he or she feels himself or herself performing in a convert hall.
Claims20
A multimedia platform for recording at least first music sounds in an information storage medium synchronously with a picture, comprising:
- a first data source producing a first sort of data containing pieces of first music data information representative of said first music sounds;
- a second data source producing a second sort of data containing pieces of video data information representative of visual images of said picture and pieces of first time data information representative of a first time defined from a first viewpoint;
- a third data source incrementing a second time defined from said first viewpoint and represented by pieces of second time data information, connected to said second data source so as to compare said second time with said first time to see whether said second time is consistent with said first time, modifying said pieces of second time data information with the negative answer so as to eliminate a time difference from between said first time and said second time, and converting said pieces of second time data information to pieces of third time data information representative of a third time defined from a second viewpoint different from said first viewpoint;
- a recorder connected to said first data source and said third data source so as to store said pieces of first music data information and said pieces of third time data information in said information storage medium;
- and
- an image generator connected to said second data source for producing said visual images.
A multimedia platform for reproducing at least first music sounds synchronously with a picture, comprising:
- a first data source outputting a first sort of data containing pieces of first music data information representative of said first music sounds and pieces of first time data information representative of a first time defined from a first viewpoint;
- a second data source outputting a second sort of data containing pieces of video data information representative of visual images of said picture and pieces of second time data information representative of a second time defined from a second viewpoint different from said first viewpoint;
- an image generator connected to said second data source so as to produce said picture from said pieces of video data information;
- a sound generator connected for generating said first music sounds from said pieces of first music data information;
- and
- a timing controller incrementing a third time defined from said second viewpoint and represented by pieces of third time data information, connected to said second data source so as to compare said pieces of third time data information with said pieces of second time data information to see whether or not said third time is consistent with said second time, connected to said first data source so as to modify said pieces of said first time data information with the negative answer for eliminating a time difference from between said second time and said third time, converting said pieces of first time data information to pieces of fourth time data information representative of a fourth time defined from said second viewpoint, comparing said pieces of fourth time data information with said pieces of third time data information to see whether or not said third time catches up said fourth time, and further connected to said sound generator so as to transfer said pieces of first music data information to said sound generator when said third time catches up said fourth time.
