Abstract

A method of rendering multimedia contents harmless is described. The method includes: reading out a predetermined word and the contents from a recording apparatus; replacing the predetermined word in transcript data with a different word, and setting the transcript data including the different word, and the predetermined word, respectively, as transcript data of harmless contents, and as transcript data of unique information; replacing the predetermined word with the different word, and setting the sound data including the different word and the predetermined word according to a time when the predetermined word appears in the firstly mentioned transcript data, respectively, as sound data of the harmless contents, and as sound data of the unique information; replacing the predetermined word in the presentation data with the different word, and the predetermined word, respectively, as presentation data of the harmless contents, and as presentation data of the unique information; recording the harmless contents; and recording the unique information.

Claims

1-17. -17. (canceled)

18. A method of rendering contents, having transcript data and sound data synchronized with each other by time, harmless in a computer having a means for setting as transcript data of unique information, a means for setting as sound data of unique information, a storage device for recording harmless contents and a storage device for recording unique information, comprising the steps of:

reading out a predetermined word from a recording apparatus by the means for setting as transcript data of unique information;

reading out the contents from a recording apparatus by the means for setting as the transcript data of unique information;

judging whether or not the transcript data contains the predetermined word by the means for setting the transcript data of unique information;

replacing the predetermined word in the transcript data with a different word, and setting the transcript data including the different word and the predetermined word as a transcript data of harmless contents and as a transcript data of the unique information, respectively, on condition that it has been judged that the transcript data contains the predetermined word by the means for setting as the transcript data of the unique information;

replacing the predetermined word of a time stamp in the sound data with the different word based upon the time stamp where the predetermined word appears in the transcript data, and setting the sound data including the different word and the predetermined word as a sound data of harmless contents and as a sound data of the unique information, respectively, on condition that it has been judged that the transcript data contains the predetermined word;

recording the harmless contents in the storage device for recording the harmless contents; and

recording the unique information in the storage device for recording the unique information;

wherein, the contents contain moving image data of a presenter, and

the method further comprises the steps of;

filtering a portion corresponding to a time stamp of the moving image data on the basis of the time stamp when a predetermined word appears in the transcript data, and setting the filtered portion as a picture data of harmless contents, on condition that it has been judged that the transcript data contains the predetermined word;

recording an image data of the harmless contents in the storage device for recording harmless contents; and

recording a portion of an original data before filtering the image data in the storage device for recording unique information as unique information.

19. The method according to claim 18, wherein the contents contains presentation data, and

the method further comprises the steps of:

determining whether or not the presentation data contains the predetermined word; and

replacing the predetermined word of the presentation data with a different word, and setting the presentation data including a different word and the predetermined word as the presentation data of harmless contents and as the presentation data of unique information, respectively, on condition that it has been judged that the presentation data contains the predetermined word.

20. The method according to claim 18, wherein the step of recording the unique information further comprises the step of registering authorization levels for accessing the unique information.

21. The method according to claim 18, wherein the step of recording the unique information further comprises the step of encrypting the unique information.

22. The method according to claim 20, further comprising the step of replacing the predetermined image with a different image, on condition that the presentation data contains a predetermined image.

23. The method according to claim 18, wherein, in the step of setting the predetermined word as sound data of the unique information, the predetermined word is replaced with the different word by using synthesized speech.
