Abstract

The present invention is a system and method of controlling the playback of the event stream information of a particular television channel by a digital video recorder (DVR). The DVR is a computer system configured with a hard drive and video decoder/encoder devices. The hardware environment of DVR (100) further comprises an input interface (102), tuner (105), MPEG-2 encoder (110), MPEG-2 decoder (120), external mass storage device (125), and central processing unit (CPU) (135), internal memory (127), operating system (140), and event stream generator (250). The system and method of controlling the playback function of the present invention is primarily implemented within event stream generator 250. Event stream generator (250) generates a new video stream for playback onto the television by incorporated the broadcasted event stream information into the selected recorded video stream.

13. In a digital video recording system configured with at least one mass storage device, a method of incorporating an event data stream from a television broadcasted video signal onto a pre-recorded video stream for playback on the television, the method comprising:

generating a user recording profile containing at least one television program, receiving a first digital video stream corresponding to the user recording profile, the first digital video stream containing a first event data stream;

recording onto the at least one mass storage device the first digital video stream;

based upon a user'"'"'s playback requirements for the first video stream, generating a second digital video stream while simultaneously capturing a second event data stream from the television broadcasted video signal; and

generating a third digital video stream by replacing the first event data stream with the second event data stream.

14. The method of claim 13 wherein generating the third digital video stream further comprises:

extracting the second event stream from the television broadcasted video signal;

locating the first event data stream within the first digital video stream; and

storing the second event data stream over the first event data stream within the first digital video stream creating the third video stream.

15. The method of claim 14 further comprises decoding the third digital video stream into analog signals for playback on the television.

16. The method of claim 14 extracting the second event stream further comprises:

decoding the second event stream; and

if the second event stream does not exist, generating a third digital video stream with a prior recorded event data stream.

17. The method of claim 13 further comprising identifying the television video signal based upon the user'"'"'s playback requirements for the first video stream.

18. The method of claim 14 extracting the second event stream further comprises:

decoding the second event stream; and

if the second event stream does not exist, generating a third digital video stream without an event stream.

19. A digital video recording system for incorporating an event data stream from a television broadcasted video signal onto a pre-recorded video stream for playback on the television, the system comprising:

a recorder module configured to record onto the at least one mass storage device a first digital video stream including a first event data stream, the first digital video stream corresponding to a user generated recording profile, the recording profile including at least one television program or program segment;

a playback module configured to generate a second digital video stream while simultaneously capturing a second event data stream from the television broadcasted video signal, the second event data stream being based upon a user'"'"'s playback requirements for the first video stream; and

an event generator module configured to generate a third digital video stream by incorporating the second event data stream into the second digital video stream.

20. The system of claim 19 wherein event generator module is further configured to:

extract the second event stream from the television broadcasted video signal;

locate the first event data stream within the first digital video stream; and

store the second event data stream over the first event data stream within the first digital video stream creating the third video stream.

21. The system of claim 20 further comprising a decoder module configured to decode the third digital video stream into analog signals for playback on the television.

22. The system of claim 20 wherein the event generator module is further configure to:

decode the second event stream; and

if the second event stream does not exist, generate a third digital video stream with a prior recorded event data stream.

23. The system of claim 20 wherein the playback module is further configured to identify the television video signal based upon the user'"'"'s playback requirements for the first video stream.

24. The system of claim 20 wherein the event generator module is further configured to:

decode the second event stream; and

if the second event stream does not exist, generate a third digital video stream without an event stream.
