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.

Claims

1. A method of reproducing an interactive disk using a network, comprising the steps of:

(a) checking whether a disk placed in a disk device is an interactive disk;

(b) receiving, from a server through a network, at least one file related with contents of the latest version compatible with a version of the inserted interactive disk; and

(c) making presentation of video or audio read from the interactive disk along with contents received from the server while synchronizing presentation time each other with reference to information of the received file.

2. The method of claim 1, wherein said step (a) further conducts a setting operation of system to be suitable to an interactive disk reproduction with reference to information of a file written on the disk.

3. The method of claim 1, wherein the files received in said step (b) includes a first file having system setting information for an interactive disk reproduction and a second file having time information for synchronizing video, audio, and the contents that are pre-recorded on the interactive disk.

4. The method of claim 3, wherein said step (c) further conducts a setting operation of system to be suitable for data reproduction with reference to information included in the first file, the setting operation including setting of a display form for presentation of video/audio/contents.

5. The method of claim 1, wherein the contents are received from the server before they are presented in synchronization with video/audio data.

6. The method of claim 1, wherein said step (a) determines the placed disk to be an interactive type if the disk includes a file having information a disk version, a content version, and an address pointing a content-providing server.

7. The method of claim 6, wherein said step (b) makes a connection to the server with reference to the address, sends the disk version to the server, and receives at least one content-related file of the latest version from the server if the server transmits in response to the transmission of disk version.

8. The method of claim 7, wherein said step (c) uses the received file if a version of the file received from the server is later than that of a corresponding file recorded on the interactive disk.

9. The method of claim 1, wherein said step (c) presents both or either of the video/audio and the contents in response to a user'"'"'s selection.

10. The method of claim 1, wherein the contents are composed of an html-formatted file, a sound file, or an image file.
