ABSTRACT:
TECHNICAL FIELD
The invention relates to a music piece distributing apparatus, a music piece receiving apparatus, a music piece distributing method, a music piece receiving method, and a music piece receiving system which can easily distribute requested music piece data through digital broadcasting.
BACKGROUND OF THE INVENTION
A communication type KARAOKE system is known as a conventional music piece distributing system. The communication type KARAOKE system has the following problems because MIDI (Musical Instrument Digital Interface) data is used.
In most cases of making MIDI data, a person who has a special skill has to listen to music and make a musical score. When MIDI data is made, special skill and knowledge are also needed and it is difficult to accurately trace the original music piece.
For reproduction by an MIDI sound source, it is difficult to equalize the tone of a musical instrument, the brace of a wind instrument, the touch of a keyboard instrument, or the playing manner or cutting of a stringed instrument with those of the original music piece. It is difficult to form the same mood as that of the original music piece while including an upsurging manner of a melody or the like.
When data is distributed by audio compression there are problems because a plurality of audio compressing techniques exist with individual characteristics, and independent formats. There is no compatibility.
It is, therefore, an object of the invention to provide a system which selects and distributes music piece data using a compression method that can be reproduced (that is, can be decoded) by a receiving apparatus.
SUMMARY OF INVENTION
According to the invention, there also is provided a music piece distributing apparatus for distributing music piece data on the basis of a request from a remote receiver, characterized by comprising:
receiving means for receiving a request signal from the receiver including at least music piece identification information and compressing system identification information; and
transmitting means for transmitting music piece data in which a music piece corresponding to the music piece identification information included in the received request signal has been compressed by a compressing system corresponding to the compressing system identification information included in the request signal.
According to the invention, there also is provided a music piece receiving apparatus for requesting music piece data of a music piece selected by the user to a remote music piece distributing apparatus and receiving and outputting the music piece data distributed from the music piece distributing apparatus, characterized by comprising:
forming means for forming a request signal including at least music piece identification information to identify the selected music piece and compressing system identification information to identify a compressing system when the music piece is distributed;
transmitting means for transmitting the formed request signal to the music piece distributing apparatus;
receiving means for receiving the music piece data distributed from the music piece distributing apparatus; and
decoding means for decoding the received music piece data by a compression decoding system corresponding to the compressing system designated by the compressing system identification information.
According to the invention, there is further provided a music piece distributing method of distributing music piece data on the basis of a request from a remote receiver, comprising the steps of:
receiving a request signal from the receiver including at least music piece identification information and compressing system identification information; and
transmitting music piece data in which a music piece corresponding to the music piece identification information included in the received request signal has been compressed by a compressing system corresponding to the compressing system identification information included in the request signal.
According to the invention, there is further provided a music piece receiving method of requesting music piece data of a music piece selected by the user to a remote music piece distributing apparatus and receiving and outputting the music piece data distributed from the music piece distributing apparatus, comprising the steps of:
forming a request signal including at least music piece identification information to identify the selected music piece and compressing system identification information to identify a compressing system when the music piece is distributed;
transmitting the formed request signal to the music piece distributing apparatus;
receiving the music piece data distributed from the music piece distributing apparatus; and
decoding the received music piece data by a compression decoding system corresponding to the compressing system designated by the compressing system identification information.
According to the invention, there is further provided a music piece distributing system in which a music piece distributing apparatus distributes music piece data on the basis of a request from a remote receiver, wherein
in the receiver,
a request signal including at least music piece identification information to identify the selected music piece and compressing system identification information to identify a compressing system when the music piece is distributed is formed and
the formed request signal is transmitted to the music piece distributing apparatus, and
in the music piece distributing apparatus,
the transmitted request signal is received from the receiver, and
the music piece data in which the music piece corresponding to the music piece identification information included in the received request signal has been compressed by the compressing system corresponding to the compressing system identification information included in the request signal is transmitted.
