1. A method of reproducing an interactive disk using a network, comprising the steps of:
- (a) checking whether a disk inserted in a disk device is an interactive disk, the disk having a file with contents pre-recorded therein;
(b) setting a system to be suitable for a reproduction of the contents, based on a result of the checking step;
(c) in response to a user'"'"'s request, transmitting, to an external source, disk version information and content version information, and a demand for a file having a latest version compatible with the inserted interactive disk and including contents having a version later than a version of the contents of the pre-recorded file;
(d) receiving, from the external source through the network, a subset of the contents of the file having the latest version compatible with the inserted interactive disk, and verifying that a version of the contents of the file having the latest version compatible with the inserted interactive disk is later than the version of the contents of the pre-recorded file;
(e) updating the contents that are pre-recorded on the interactive disk based on the received subset if the version of the contents of the file having the latest version compatible with the inserted interactive disk is verified to be later than the version of the contents of the pre-recorded file;
(f) resetting the system to be suitable for a reproduction of the updated contents; and
(g) presenting the updated contents by presenting the subset synchronously with video or audio data read from the interactive disk prior to or while receiving a second subset.

Abstract
The present invention relates to an interactive disk reproducing method using a network. The present method downloads various content-related information associated with A/V data pre-recorded on a placed interactive disk from a remote content-providing server connected through a network, and makes presentation of video or audio reproduced from the interactive disk along with contents received from the server while synchronizing presentation time of the A/V data and the contents with reference to the downloaded content-related information.

8. An apparatus for reproducing an interactive disk using a network, comprising:
-
a controller configured to check whether a disk inserted in a disk device is an interactive disk and generate a corresponding checking result, to set a system to be suitable for a reproduction of contents, based on the checking result, in response to a user'"'"'s request, transmit, to an external source, disk version information and content version information, and a demand for a file having a latest version compatible with the inserted interactive disk and including contents having a version later than a version of the contents of the pre-recorded file, to receive, from the external source through the network, a subset of the contents of the file having the latest version compatible with the inserted interactive disk, to verify that a version of the contents of the file having the latest version compatible with the inserted interactive disk is later than the version of the contents of the pre-recorded file, to update contents that are pre-recorded on the interactive disk based on the received subset if the version of the contents of the file having the latest version compatible with the inserted interactive disk is verified to be later than the version of the contents of the pre-recorded file, and to reset the system to be suitable for a reproduction of the updated contents; and a presentation engine configured to present the updated contents by presenting the subset synchronously with video or audio data read from the interactive disk prior to or while receiving a second subset. - View Dependent Claims (9, 10, 11, 12, 13, 14)
