First Claim
1. A method for reproducing contents information in an interactive optical disc device, comprising the steps of:
- a) synchronizing and reproducing data read from an interactive optical disc and contents information sent and downloaded from a contents provider server connected via the Internet;
b) if the sending of said contents information from said contents provider server is suspended or delayed, generating a command for requesting re-sending of specific contents information, based upon information about a size of said downloaded contents information, and sending the generated command to said contents provider server; and
c) reproducing said specific contents information re-sent from said contents provider server in response to said command together with data read from said interactive optical disc while re-synchronizing it with said data read from said interactive optical disc.

Abstract
Disclosed herein are a method for reproducing contents information in an interactive optical disc device and a method for providing contents information in a contents provider server. The interactive optical disc device is connected with the contents provider server via the Internet to receive a variety of contents information provided from the contents provider server. When the sending of the contents information from the contents provider server to the interactive optical disc device is suspended or delayed due to a network connection loss on the Internet or an insufficient storage capacity of a buffer memory in the interactive optical disc device, contents information re-sent from the contents provider server and a data stream read from an interactive DVD are re-synchronized and reproduced. Therefore, a user of the interactive optical disc device can normally watch more various contents information.
