Abstract
An audio recording and reproducing apparatus includes a controller for controlling the entire behaviors, hard disc for write and read of audio data, audio compression/expansion circuit for expanding compressed audio data, and external I/O port. The audio recording and reproducing apparatus is connected to a network service center to obtain desired music data from storage of the network service center and to store it in the hard disc.
Claims45
An audio reproducing apparatus, comprising:
- control means for controlling entire behaviors;
- storage means for writing and reading data;
- audio expanding means for expanding compressed audio data;
- external I/O means for transferring incoming and outgoing data, the transferring of incoming and outgoing data operative to charge an account associated with the transfer of such incoming and outgoing data;
- and
- a personal computer standard bus for transmitting data among said control means, said storage means, said audio expanding means and said external I/O means, so that compressed audio data is stored in said storage means, and said compressed audio data is transferred to and expanded by said audio expanding means to be audibly reproduced.
3 more elements
An audio recording apparatus, comprising:
- control means for controlling entire behaviors;
- storage means for writing and reading data;
- audio compressing means for compressing audio data;
- external I/O means for transferring incoming and outgoing data;
- and
- a personal computer standard bus for transmitting data among said control means, said storage means, said audio compressing means and said external I/O means, wherein incoming data sent in a predetermined format is transferred through said external I/O means, and compressed audio data is generated from the transferred incoming data and stored in said storage means, the transferring of incoming and outgoing data operative to charge an account associated with the transfer of such incoming and outgoing data.
