Abstract

In an information system including an information processing apparatus and an in-vehicle apparatus, a synchronization process is performed in a highly efficient manner, which allows an improvement in usability in playing back playable data on the in-vehicle apparatus. The information processing apparatus acquires a list of playable data already existing in the in-vehicle apparatus and produces synchronization data by extracting, as the synchronization data, playable data from the playable data existing in the information processing apparatus in accordance with the acquired list such that the extracted playable data does not include any part of the playable data already existing in the in-vehicle apparatus.

Claims

1. An information processing apparatus capable of producing synchronization data to be used in a synchronization process by which data existing in an in-vehicle apparatus and playable by the in-vehicle apparatus is to be synchronized in terms of content with playable data existing in the information processing apparatus, and supplying the produced synchronization data to the in-vehicle apparatus,

wherein the synchronization data is produced such that when playable data selected by a user from the playable data existing in the information processing apparatus is supplied to a portable device capable of supplying this playable data to the in-vehicle apparatus, the synchronization data is produced by extracting playable data as the synchronization data from the playable data existing in the information processing apparatus such that the extracted playable data does not include any part of the playable data supplied to the portable device.

2. The information processing apparatus according to claim 1, wherein the device is a portable audio player.

3. The information processing apparatus according to claim 1, wherein the playable data is music data.

4. The information processing apparatus according to claim 1, wherein the information processing apparatus performs the synchronization process via wireless or wired communication.

5. An information system including an information processing apparatus and an in-vehicle apparatus, the information system being capable of performing a synchronization process including producing, by the information processing apparatus, synchronization data to be used in the synchronization process by which data existing in the in-vehicle apparatus and playable by the in-vehicle apparatus is to be synchronized in terms of content with playable data existing in the information processing apparatus, and supplying the produced synchronization data to the in-vehicle apparatus,

wherein when playable data selected by a user from playable data existing in the information processing apparatus is supplied from the information processing apparatus to a portable device capable of supplying this playable data to the in-vehicle apparatus, the information processing apparatus produces the synchronization data by extracting playable data as the synchronization data from the playable data existing in the information processing apparatus such that the extracted playable data does not include any part of the playable data already supplied to the portable device.

6. The information system according to claim 5, wherein the device is a portable audio player.

7. The information system according to claim 5, wherein the playable data is music data.

8. The information system according to claim 5, wherein the synchronization process is performed via wireless or wired communication.
