Abstract
PURPOSE:To prevent a blank in reproduction by dividing music information to a main memory at every channel, down-loading information through each channel, transferring the music information of the designated channel from the main memory to a sub-memory and using the sub memory for a load. CONSTITUTION:The music information extracted from a database 1 by a host computer 2 is transmitted to a terminal equipment 5 via a public line 3, saved in a main memory 8a at every channel sequentially by a CPU 6 and the music information of a desired genre designated by a channel selection means 7 from the main memory 8a is transferred to the sub memory 8b, where the information is reproduced by the CPU 6, loaded to a reproduction means 9 and reproduced continuously. Then the music information is transferred to the sub memory 8b to save the music information of the same channel sequentially to the idle area in the main memory 8a and the succeeding music information is transferred to the sub memory 8b reproduced and erased from the main memory 8a. Thus, reproduction is attained without intermission.

生システム。[Claims] 1. A host computer 2 that transmits arbitrary music information from a database 1 storing a large amount of binary encoded music information to a terminal device 5 via a public line 3; A CPU 6 downloads music information of the genre specified by the channel selection means 7 to the main memory 8a divided for each channel and loads it from the main memory 8a to the secondary memory 8b for reproduction, and the music processed by the CPU for reproduction. 1. A music transmission and playback system used for BGM playback, characterized by comprising a means 9 for playing back information. 2. A database 21 consisting of a large number of compressed music information that has been binary encoded and compressed by converting frequently occurring data units into short bits, and the compressed music information in this database is stored in the memory (1) and The bit pattern table for restoring the compressed music information is stored in the memory (2), and the converted/restored bit string is stored in the memory (3), and the restoring CPU having a plurality of registers stores the bit pattern table in the memory (2). 1), (2), and (3), a data restoration device 26 that can freely read or write data, a main CPU 27 that reproduces music information of a genre specified by the channel selection means 28, and this main CPU.
1. A music transmission and playback system used for BGM playback, characterized in that it comprises means 29 for sequentially playing back music information processed in U.
