The invention enables a body of information to be easily manipulated (e.g., summarized, rearranged, edited, selectively accessed or searched) to facilitate use of the information by a user. The body of information is represented by at least two sets of temporally related data. Manipulation of a second one of the sets of data in a predetermined manner is accomplished indirectly through direct manipulation of a first one of the sets of data in the predetermined manner. Where the body of information is represented by more than two sets of temporally related data, the additional sets of data can also be manipulated in a similar fashion. The invention takes advantage of the fact that some forms or types of data more readily lend themselves to particular manipulations and operations than other forms or types of data. In a particular embodiment of the invention, digital text data representing a body of information (which is also represented by video and/or audio data) is manipulated, the digital text data is aligned with either the digital video data or digital audio data of the body of information, and the digital video data or digital audio data is manipulated according to the manipulation of the digital text data and the alignment of the digital text data with the digital video data or digital audio data. The other of the video or audio data (if present) can be manipulated by aligning that data with either the text data or the previously manipulated video or audio data, then manipulating the other of the video or audio data according to the previous manipulation of the data with which the other of the video or audio data has been aligned. |
