Abstract

A computer microcontroller (225) controls the operational functions of a video reporter (10) for superimposing real time emergency broadcast messages and information on a television picture concurrently with any programing in progress. The video reporter (10) has a signal splitting means for splitting a television broadcast signal such that the signal is transmitted to the video reporter and a TV. A tuner (210) constantly scans predetermined channels for video reporter messages of the type to be superimposed. The video messages are embedded in intelligent data having a preamble (810) which enables the microcontroller to identify the message type and determine whether it is superimposable.

There is a decoding means (230) for decoding the video reporter data and a message extracting means (240) for extracting messages from the video reporter data. An overlay generating means (250) generates a video signal from the video reporter data and the video signal can be superimposed over any television picture of the programing in progress, including VCR, video game, and other programing by means for superimposing the video signal over the television picture (260).

Claims

1. A method for superimposing a real time video reporter message on a television picture concurrently with any programing in progress, which comprises the steps of:

splitting a television broadcast signal into at least a first television signal and a second video reporter signal;

continuously tuning the video reporter signal for predetermined channels having video reporter data thereon;

repeating the tuning step until video reporter data is detected;

decoding the video reporter data;

extracting messages from the video reporter data;

selecting the messages to be superimposed on the television picture;

generating a video signal from the video reporter data for superimposing over the television picture; and

,

superimposing the video signal over the television picture of the programing in progress.

2. The method of claim 1 further comprising the step of synthesizing an audio message from the messages to be superimposed following the selecting step.

3. The method of claim 2 further comprising the step of generating an audible tone for alerting a viewer to the messages to be superimposed before the superimposing step.

4. The method of claim 3 further comprising the step of producing a visual indicator to alert a viewer to the messages to be superimposed before the superimposing step.

5. The method of claim 4 wherein the television broadcast signal includes teletext and closed caption text data, and the superimposing means is capable of superimposing various data simultaneously over the television picture in progress, the various data selected from the group consisting of video reporter data, teletext and closed caption text data.

6. The method of claim 5 further comprising the step of powering a television on before the superimposing step and powering the television off following the superimposing step.

7. The method of claim 6 further comprising the step of interrupting VCR programing in progress before the superimposing step, such that the various data can be superimposed over a VCR programing television picture.

8. The method of claim 6 further comprising the step of interrupting video game programing in progress before the superimposing step, such that the various data can be superimposed over a video game programing television picture.

9. The method of claims 7 or 8, further comprising the step of temporarily storing the messages to be superimposed following the superimposing step.

11. The video reporter of claim 3 further comprising a first programing means for selectively programing input data, the input data includes the channels to be scanned and the type of messages to be superimposed on the television picture.

12. The video reporter of claim 11 further comprising storing and retrieving means for storing and retrieving the video reporter data and the input data.

13. The video reporter of claim 12 further comprising a second programing means for selectively programing at least one video reporter-specific address such that the video reporter can receive the television broadcast signal from a particular broadcast station as desired.

14. The video reporter of claim 13 further comprising text to speech synthesizing means for synthesizing an audio message from the messages to be superimposed.

15. The video reporter of claim 14 further comprising tone generating means for generating an audible tone for alerting a viewer to the messages to be superimposed.

16. The video reporter of claim 14 further comprising visual indicator producing means for producing a visual indicator to alert a viewer to the message.

17. The video reporter of claim 16 wherein the television broadcast signal includes teletext and closed caption text data, and the superimposing means is capable of superimposing various data simultaneously over the television picture in progress, the various data selected from the group consisting of video reporter data, teletext and closed caption text data.

18. The video reporter of claim 17 further comprising computer microcontroller means for operating the video reporter.

19. The video reporter of claim 18 further comprising printing means for printing the various data.

20. The video reporter of claim 19 further comprising VCR interrupting means for interrupting VCR programing in progress, such that the various data can be superimposed over a VCR programing television picture.

21. The video reporter of claim 20 further comprising video game interrupting means for interrupting video game programing in progress, such that the various data can be superimposed over a video game programing television picture.

22. The video reporter of claim 21 further comprising television power switching means for powering a television on and off.

23. The video reporter of claim 22 wherein the video reporter is housed within a television set.

10. A video reporter for superimposing real time emergency broadcast messages and information on a television picture concurrently with any programing in progress comprising;

signal splitting means for splitting a television broadcast signal into at least a first television signal and a second video reporter signal;

tuning means for continuously tuning the video reporter signal for predetermined channels having video reporter data thereon;

decoding means for decoding the video reporter data;

message extracting means for extracting messages from the video reporter data;

message selecting means for selecting the messages to be superimposed on the television picture;

overlay generating means for generating a video signal from the video reporter data for superimposing over the television picture; and

,

superimposing means for superimposing the video signal over the television picture of the programing in progress.

24. A method for controlling and coordinating the operation of a video reporter involved in the process of simultaneously superimposing various data over a television picture of any programing in progress, which comprises the steps of:

constantly reading user input data storage means for detecting user input data;

constantly determining command functions of a video reporter from the input data;

constantly revising the command functions in consideration of the user input data;

instructing a tuning means for continuously tuning a video reporter signal to scan predetermined channels until video reporter data is detected by the tuning means;
