Abstract

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) includes an input interface (102), tuner (105), MPEG-2 encoder (120), MPEG-2 decoder (110), external mass storage device (125), a 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 incorporating the broadcasted event stream information into the selected recorded video stream.

Claims

1. In a digital video recording system configured with a processor and at least one mass storage device, a method for incorporating a current event data stream from a television broadcasted video signal onto a pre-recorded video stream for playback on a television set, said method comprising:

retrieving, by said processor, a first digital video stream from the at least one mass storage device, said first digital video stream comprising television program content and a first event data stream;

ascertaining, by said processor, whether a current event is located in the current event data stream in the television broadcasted video signal;

if said ascertaining ascertains that the current event is located in the current event data stream in the television broadcasted video signal, then

automatically replacing, by said processor, the first event data stream with the current event data stream in the retrieved first digital video stream to generate a composite video stream containing the television program content and the current event data stream;

after said replacing the first event data stream, playing back, by said processor, on a screen of the television set the television program content concurrently with the current event data stream, said television program content and said current event data stream being concurrently visible on the screen during said playing back;

if said ascertaining ascertains that the current event is not located in the current event data stream in the television broadcasted video signal, then

automatically retaining, by said processor, the retrieved first digital video stream without replacing the first event data stream in the retrieved first digital video stream;

after said retaining the retrieved first digital video stream, playing back, by said processor, on the screen of the television set the television program content in the retained first digital video stream.

2. The method of claim 1, wherein said ascertaining ascertains that the current event is located in the current event data stream in the television broadcasted video signal.

3. The method of claim 2, wherein the screen of the television set consists of a first portion and a second portion, wherein said playing back comprises concurrently playing back the television program content on the first portion of the screen and playing back the current event data stream on the second portion of the screen, and wherein the first portion and the second portion are mutually exclusive.

4. The method of claim 1, wherein said ascertaining ascertains that the current event is not located in the current event data stream in the television broadcasted video signal.

5. The method of claim 1, said method further comprising:

said processor determining that the first event data stream includes a first event, wherein said ascertaining is performed in response to said determining that the first event data stream includes the first event.

6. The method of claim 1, said method further comprising:

said processor receiving the first digital video stream comprising the television program content, said first digital video stream containing a first event data stream; and

prior to said retrieving, said processor recording the received first digital video stream onto the at least one mass storage device.

7. The method of claim 6, wherein said recording the received first digital video stream is based upon a user'"'"'s playback requirements for the first digital video stream.

8. A digital video recording system for incorporating a current event data stream from a television broadcasted video signal onto a pre-recorded video stream for playback on a television set, said system comprising:

a processor;

a mass storage device coupled to the processor;

a computer readable memory coupled to the processor;

first program instructions to retrieve a first digital video stream from the at least one mass storage device, said first digital video stream comprising television program content and a first event data stream;

second program instructions to ascertain whether a current event is located in the current event data stream in the television broadcasted video signal;

third program instructions to respond to ascertaining that the current event is located in the current event data stream in the television broadcasted video signal, said third program instructions comprising;

program instructions to automatically replace the first event data stream with the current event data stream in the retrieved first digital video stream to generate a composite video stream containing the television program content and the current event data stream; and

program instructions to play back, on a screen of the television set after the first event data stream is replaced, the television program content concurrently with the current event data stream, said television program content and said current event data stream being concurrently visible on the screen during said playing back;

fourth program instructions to respond to ascertaining that the current event is not located in the current event data stream in the television broadcasted video signal, said fourth program instructions comprising;

program instructions to automatically retain the retrieved first digital video stream without replacing the first event data stream in the retrieved first digital video stream; and

program instructions to play back on the screen of the television set, after the retrieved first digital video stream is retained, the television program content in the retained first digital video stream,

wherein the first program instructions, the second program instructions, the third program instructions, and the fourth program instructions are stored on the mass storage device for execution by the processor via the computer readable memory.

9. The system of claim 8, wherein the screen of the television set consists of a first portion and a second portion, wherein said program instructions to play back said television program content comprise program instructions to concurrently play back said television program content on the first portion of the screen and play back the current event data stream on the second portion of the screen, and wherein the first portion and the second portion are mutually exclusive.

10. The system of claim 8, said system further comprising:

fifth program instructions to determine that the first event data stream includes a first event, wherein said second program instructions to ascertain comprise program instructions to ascertain, in response to a determination having been made that the first event data stream includes the first event, whether the current event is located in the current event data stream in the television broadcasted video signal,

wherein the fifth program instructions are stored on the mass storage device for execution by the processor via the computer readable memory.

11. The system of claim 8, said system further comprising:

fifth program instructions to receive the first digital video stream comprising the television program content, said first digital video stream containing a first event data stream; and

sixth program instructions to record, prior to the first digital video stream having been retrieved from the at least one mass storage device, the received first digital video stream onto the at least one mass storage device,

wherein the fifth program instructions and the sixth program instructions are stored on the mass storage device for execution by the processor via the computer readable memory.

12. The system of claim 11, wherein a recording of the received first digital video stream via execution of the sixth program instructions is based upon a user'"'"'s playback requirements for the first digital video stream.
