Abstract

A system and method are provided for displaying a uniform network resource locator embedded in a time-based medium. In one embodiment, the time-based medium can be a movie file having an uniform network resource locator embedded by association with a track in the movie file. In another embodiment, the time-based medium can be a video signal having encoded information defining an embedded uniform network resource locator. An output for display is generated based upon the time-based medium where display of the output shows the embedded uniform network resource locator to a user such that the embedded uniform network resource locator is active during display of the output. The user is then allowed to activate the embedded uniform network resource locator. In response to activation by the user, the embedded uniform network resource locator is followed to retrieve a resource addressed by the embedded uniform network resource locator.

Claims

1. A system for displaying a uniform network resource locator embedded in a time-based medium, comprising:

a data storage device storing a time-based medium having an embedded uniform network resource locator;

a playback application operable to access the data storage device, the playback application further operable to read the time-based medium, interpret the time-based medium and generate an output for display, the output including the embedded uniform network resource locator where the embedded uniform network resource locator is active;

a display coupled to receive the output of the playback application and to display the output to a user of the system; and

a user input device operable to provide information to the playback application, such that the user can select and activate the embedded uniform network resource locator; and

the playback application operable to follow the embedded uniform network resource locator to retrieve a resource addressed by the embedded uniform network resource locator if the embedded uniform network resource locator is activated.

2. The system of claim 1, wherein the time-based medium is a movie file having embedded Internet/intranet uniform resource locators.

3. The system of claim 2, wherein the movie file comprises:

a plurality of tracks each defining a sequence of samples for playback by a playback application; and

a URL track associated with one of the plurality of tracks, the URL track defining a uniform resource locator in association with one or more samples of the associated track;

such that the URL is active during playback of the movie file concurrent with the associated samples.

4. The movie file of claim 3, wherein the plurality of tracks includes an image track defining a sequence of images for playback by the playback application to generate video, and the URL track is associated with the image track.

5. The system of claim 3, wherein the plurality of tracks includes an audio track defining a sequence of audio samples for playback by a playback application to generate sound, and the URL track is associated with the audio track.

6. The system of claim 1, wherein the output displayed to the user includes a uniform network resource locator window that shows a history of uniform network resource locators active at some point in the display window.

7. The system of claim 1, wherein the embedded uniform network resource locator is a hot spot.

8. The system of claim 1, wherein the embedded uniform network resource locator is a hypertext link.

9. The system of claim 1, wherein the playback application follows the activated embedded uniform network resource locator by invoking a web browser to retrieve the resource addressed by the embedded uniform network resource locator.

10. The system of claim 1, wherein the system is implemented using a personal computer having:

a memory operable to store the playback application; and

a processor coupled to the data storage device, the memory, the display and the user input device, the processor operable to execute the playback application.

11. A system for distributing a video signal having an encoded uniform network resource locator, comprising:

an encoding system operable to generate a video signal including video and encoded information, the encoded information defining a uniform network resource locator embedded in the video; and

a decoding system operable to receive the video signal, the decoding system further operable to decode the encoded information from the video signal, to display the video with the uniform network resource locator embedded in the video to a user, and to allow the user to select and activate the embedded uniform network resource locator; and

the decoding system operable to follow the embedded uniform network resource locator to retrieve a resource addressed by the embedded uniform network resource locator if the embedded uniform network resource locator is activated.

12. The system of claim 11, wherein the encoding device comprises:

a data storage device storing a time-based medium having an embedded network uniform resource locator;

an encode unit operable to access the data storage device, the encode unit further operable to read and interpret the time-based medium and operable to encode the embedded uniform network resource locator into the video signal; and

video output terminals operable to receive the video signal and to provide the video signal for receipt by the decoding system.

13. The system of claim 11, wherein the decoding unit comprises:

a video receiver operable to receive the video signal;

a decode unit operable to receive the video signal from the video receiver, the decode unit further operable to decode the encoded information from the video signal, to generate and provide the video with the embedded uniform network resource locator and to generate and provide data defining the embedded uniform network resource locator;

a display operable to receive the video with the embedded uniform network resource locator from the decode unit, the display further operable to display the video with the embedded uniform network resource locator to a user;

a processing unit operable to receive the data from the decode unit, the processing unit further operable to process the data to monitor the embedded uniform network resource locator; and

a user interface operable to communicate with the processing unit, such that the user can provide input to the processing unit for activating the embedded uniform network resource locator.

14. The system of claim 13, wherein the user interface includes a web browser operable to retrieve the resource addressed the activated embedded uniform network resource locator.

15. The system of claim 11, further comprising a distribution network coupled to receive the video signal from the encoding system, and the distribution network operable to transmit the video signal to the decoding system.

16. The system of claim 11, wherein the video signal from the encoding system is recorded on a video cassette recorder tape and the video cassette recorder tape is provided to the decoding system.

17. The system of claim 15, further comprising a plurality of additional decoding systems, and wherein the encoding system is associated with a television station distributing a video signal to the decoding systems.

18. The system of claim 17, wherein the distribution network is a cable network.

19. The system of claim 17, wherein the distribution network is a direct broadcast satellite network.

20. A method for displaying a uniform network resource locator embedded in a time-based medium, comprising:

embedding a uniform network resource locator in a time-based medium;

generating an output for display based upon the time-based medium, where display of the output shows the embedded uniform network resource locator to a user where the embedded uniform network resource locator is active during display of the output;

allowing the user to activate the embedded uniform network resource locator; and

following the embedded uniform network resource locator to retrieve a resource addressed by the embedded uniform network resource locator in response to activation by the user.

21. The method of claim 20, wherein embedding the uniform network resource locator comprises embedding the uniform network resource locator in a movie file, where the uniform network resource locator is associated with a track in the movie file.

22. The method of claim 20, wherein embedding the uniform network resource locator comprises encoding information into a video signal that defines the embedded uniform network resource locator, and wherein generating the output for display comprises decoding the encoded information from the video signal.

23. The method of claim 20, wherein generating the output for display includes generating video output during which the embedded uniform network resource locator is active for a defined period of time.
