1. Field of the Invention
The present invention relates to a data processing method, a reproduction apparatus such as a portable player and an information processing apparatus such as a computer for providing services related to content data.
2. Description of the Related Art
For example, there are systems for managing reproduction history of a plurality of music data (audio data) stored in a hard disk of a personal computer and determining preference of the user based on the reproduction history.
In such a system, the user connects a portable player to a personal computer and outputs music data read from a hard disk as the above personal content data to the portable player for storing the same.
Then, the user reproduces the content data stored in the portable player while the user goes outside.
However, in the above system of the related art, since a user often plays back music data by the portable player, preference of the user cannot be specified correctly only by using reproduction history data in the personal computer, so it suffers from the disadvantage that services according to the users' preferences cannot be provided.
