Music station for producing visual images synchronously with music data codes
First Claim
1. A music station for producing visual images of tones to be produced together with visual images of a performance, comprising:
- a receiver connected to a communication channel, and receiving pieces of music data representative of said tones to be produced and pieces of first timing data mixed with said pieces of music data;
another receiver connected to another communication channel independent of said communication channel, and receiving pieces of video data representative of said performance carried out in synchronism with said tones produced at another station remote from said music station and pieces of second timing data mixed with said pieces of video data and delivered to said another communication channel concurrently with the delivery of said pieces of first timing data to said communication channel, respectively;
a timing adjuster connected to said receiver and said another receiver, and eliminating a time lag from between each of said pieces of first timing data and associated one of said pieces of second timing data so as to establish said pieces of video data and said pieces of music data in synchronization with one another;
a display unit having plural image producing areas at least two of which are assigned to visual images of said performance and visual images of said tones, respectively; and
a display driver connected to said receiver, said another receiver and said display unit, producing an image-carrying signal representative of said visual images of said performance and another image-carrying signal representative of said visual images of said tones, and supplying said image-carrying signal and said another image-carrying signal to said display unit so that said visual images of said performance and said visual images of said tones are produced in the at least two areas, respectively, in correlation with one another.

Abstract
In order to make a tutor give a remote music lesson to a trainee, the audio-visual station transmits MIDI music data codes/time stamp data codes and click time data codes through a packet switching network and an audio-visual signal, which expresses real images of tutor'"'"'s hands on the keyboard, and click signal through a teleconference system to another audio-visual station; the controller for the trainee makes the internal clock synchronous with the internal clock for the tutor through the pairing work between the click time data codes and the click signals so that the images of note bars and real images are synchronously produced on a display unit in front of the trainee'"'"'s keyboard; moreover, while the tutor'"'"'s exhibition is being carried out, any oral direction does not reach the trainee so that the trainee concentrate himself to the exhibition.

13. A music station for producing visual images of tones, comprising:
-
a receiver connected to a communication channel, and receiving pieces of music data representative of said tones to be produced and pieces of time data each representative of a time at which associated one of said tones is to be produced;
a display unit having an image producing area where said visual images of said tones are to be produced;
a timing generator connected to said receiver, and analyzing said pieces of time data so as to determine timings at which said visual images of said tones appear in said image producing area on said display unit; and
a display driver connected to said receiver, said timing generator and said display unit, producing an image-carrying signal representative of said visual images of said tones on the basis of said pieces of music data, and supplying said image-carrying signal to said display unit so as to produce said visual images of said tones in said image producing area on said display unit as if said visual images of said tone are produced at said timings. - View Dependent Claims (14, 15, 16, 17, 18)

19. A music station for producing a music passage of tones and voice, comprising:
-
a receiver connected to a communication system, and receiving pieces of music data representative of said tones;
a tone generating system connected to said receiver so as to produce said music passage of said tones;
another receiver connected to said communication system, and receiving pieces of audio data representative of said voice for producing an audio signal;
a signal-to-sound converter for converting said audio signal to said voice;
a controller connected between said receiver and said tone generating system, and analyzing said tones to be produced to see whether or not a loudness of said tones exceeds a threshold for producing a control signal; and
a switch connected between said another receiver and said signal-to-sound converter, and responsive to said control signal so as to interrupt said audio signal while said loudness is keeping over said threshold. - View Dependent Claims (20, 21)
