Abstract

The method of storing a time based stream of information to generate a presentation is provided for in which a processing system is used. The methods provide for deleting a selected time based stream of information from the storage medium. In one embodiment, a process manager in the processing system deletes selected information in response to a user selection command. This process manager may further check for reference data to the information and only delete the information is no more than one reference to the selected information exists. A trash depository may be used as an intermediary holding area for the information prior to is deletion. Other aspect of the present invention relating to the processing system conserving storage for a time based stream of information for use in authoring a presentation are also described.

Claims

1. A method of destructively editing a time based stream of information in a processing system, the method comprising:

capturing the time based stream of information from an information source having a transfer rate into a storage of the processing system;

partitioning in a first display area of a display of the processing system the time based stream of information into a first portion and a second portion, the first portion and the second portion being displayed as a first thumbnail and a second thumbnail in the first display area, wherein the first thumbnail includes a first reference referenced to a first segment of the time based stream of information stored in the storage and the second thumbnail includes a second reference referenced to a second segment of the time based stream of information stored in the storage;

displaying in a second display area of the display of the processing system for authoring a presentation having a plurality of video clips in sequence, wherein each of the plurality of the video clips can be formed by selecting one of the thumbnails displayed in the first display area and placing the selected thumbnail into a particular location of the second display area;

in response to a user input, playing in a third display area of the display the presentation authored in the second display area;

selecting the first portion of the time based stream of information from the first display area;

in response to receiving a user deletion command for deleting the first portion, determining whether there are multiple references from one or more video clips of the second display area and/or from thumbnails displayed in the first display area that are currently referenced to the first portion; and

permanently deleting the first portion of the time based stream of information from the storage if there is no more than one reference currently referenced to the first portion, without examining storage capacity state, in response to the user deletion command such that the first portion is no longer stored on the storage and is thereby destructively edited;

providing reference data corresponding to the stored time based stream information an wherein the selecting is by extracting the reference data from at least a portion of a reference, wherein the reference forms at least one new reference with reference data to the remaining time based stream of information, and

wherein the extracted reference data is from a portion nested within the reference and the reference splits into a first new reference corresponding to the time based stream of information prior to the extracted reference data and a second new reference corresponding to the time based stream of information after the extracted reference data.

2. The method of claim 1, further including depositing the extracted reference data in a trash depository prior to deleting the first portion.

3. The method of claim 1, further comprising permanently eliminating the first portion of the time based stream of information from storage directly without an intermediary step.

4. A method for managing storage in a processing system, comprising:

selecting the first portion of the time based stream of information in response to a user selection command;

in response to a deletion command received from a user for deleting the selected first portion determining whether the first portion is represented by more than one reference data containing processing information corresponding to the time based stream of information; and

permanently deleting the first portion of the time based stream of information from the storage of the processing system if there is no more than one reference data associated with the first portion containing processing information corresponding to the time based stream of information, without examining storage capacity state,

such that the first portion is no longer stored on the storage and is thereby destructively edited;

wherein the selecting is by extracting corresponding reference data from at least a portion of a reference, the reference forms at least one new reference to the remaining time based stream of information after extracting; and

wherein the extracted reference data is nested in the reference and the reference splits into a first new reference corresponding to the time based stream of information prior to the extracted reference data and a second new reference corresponding to the time based stream of information after the extracted reference data.

5. The method of claim 4, further including depositing corresponding reference data in a trash depository prior to deleting the first portion of the time based stream of information.

6. The method of claim 5, wherein the deleting further includes determining if a cancel command is not received.

7. The method of claim 4, wherein if a cancel command is received, the extracted reference data is replaced in the reference and the first portion is not deleted.

8. A method of claim 4, further comprising permanently eliminating the first portion of the time based stream of information from storage directly without an intermediary step.

9. A time based stream of information processing system comprising:
