Method and apparatus for digital data distributing system
First Claim
1. A system for distributing digital data to a portable device including a recording medium, comprising:
- a storage device which stores said digital data;
a determination device which determines a bit rate of said digital data in accordance with a predetermined distribution condition when the digital data fetched from said storage device is distributed to said portable device; and
a transmission device which transmits the digital data fetched from said storage device to said portable device at a bit rate determined by said determination device.

Abstract
Disclosed is a data distributing system for distributing music data consisting of digital sound data, for example, to a portable device having a memory card. The system has a function for changing a bit rate at which data distribution is executed based on distribution conditions associated with usage or use conditions of the portable device. This data distributing system can construct a library system having stored therein a lot of music data for every music title. A user can download desired content data from the system to the memory card so as to be in conformance with usage of a portable device or use conditions such as the remaining capacity of the memory card.
