Abstract

A method, system, and computer program product for presenting text from multimedia data to a user is provided. In one embodiment, multimedia data containing associated text data is received by a data processing system. The associated text data is extracted from the multimedia data. The associated text data is then outputted without outputting moving images from the multimedia data.

Claims

1. A method for presenting text from moving video to a user, the method comprising:

receiving multimedia data containing a plurality of moving video frames and an associated plurality of sets of text data, wherein the associated plurality of sets of text data are associated in time with the plurality of moving video frames, wherein the plurality of sets of text data includes a first text data set associated with a first plurality of moving video frames of the multimedia data, and a second text data set associated with a second plurality of moving video frames of the multimedia data;

extracting the associated plurality of sets of text data from the multimedia data;

extracting a first video frame, from the first plurality of moving video frames, associated with the first text data set to form a first still image;

extracting a second video frame, from the second plurality of moving video frames, associated with the first text data set to form a second still image;

outputting the first text data set in association with the first still image;

outputting the second text data set in association with the second still image;

wherein the step of extracting the associated plurality of sets of text data comprises parsing the multimedia data to determine the first text data set and the first video frame of the first plurality of moving video frames and discarding remaining moving video frames from the first plurality of moving video frames.

2. The method as recited in claim 1, wherein the first text data set and the second text data set are presented in association with the first still image and the second still image, respectively, to the user simultaneously.

3. The method as recited in claim 2, wherein the first text data set and the second text data set are presented in association with the first still image and the second still image, respectively, in separate portions of a static display.

4. The method as recited in claim 1, wherein the first text data set and the second text data set are presented in association with the first still image and the second still image, respectively, to the user individually in a sequential order.

5. The method as recited in claim 4, wherein a next set of text data in the sequential order is presented in response to an indication by the user to display the next set of text data.
