Viewer controlled multi-function system for processing television signals
First Claim
1. An apparatus for manipulating information embedded in video program signals comprising:
- an input means having an input for receiving a video program signal, said input means recognizing and segregating a selected portion of the video program signal as a data signal at an output;
a digital signal processor having an input connected to said input means output for modifying the data signal to exclude objectionable content and generating the modified data signal at an output;
a radio frequency modulator having an input connected to said digital signal processor output and being responsive to the modified data signal for generating a modified video program signal recognizable by a standard television signal decoder circuit whereby the objectionable content is not available to a viewer upon subsequent display of the modified video program signal; and
wherein said input means includes a compressed video packet microcontroller for recognizing and segregating a compressed video packet information portion of the video program signal and generating the data signal as a compressed video packet data signal, said digital signal processor processes the compressed video packet data signal and generates the processed compressed video packet data signal, and said radio frequency modulator generates the modified video program signal with a picture-in-picture image.

Abstract
An apparatus and a method for manipulating video, audio, closed-captioned and compressed video packet data embedded in video programming signals includes a video signal processor for embedding data into a broadcast video signal prior to broadcast, the video signal containing at least one of video information, audio information, closed-captioned information and video packet data information. The embedded data is embedded in at least one predetermined line of at least one predetermined frame of the video program signal. An instruction defining a predetermined screening format for at least one of the video information, the audio information, the closed-captioned information and the video packet data information is stored and a circuit is responsive to the embedded data and the stored instruction for reproducing the information in the video signal in a predetermined screening format.

9. A method for modifying a selected portion of a video program signal comprising the steps of:
-
a. recognizing and segregating a selected portion of a video program signal as a data signal;
b. recognizing components of the data signal as being objectionable to a viewer;
c. modifying the data signal to exclude objectionable content; and
d. generating the modified data signal as a modified video program signal recognizable by a standard television signal decoder circuit whereby the objectionable content is not available to a viewer upon subsequent display of the modified video program signal wherein said step a. is performed on a compressed video packet information portion of the video program signal said steps b. and c. are performed by processing the closed-captioned information and said step d. is performed by generating the modified video program signal with a picture-in-picture image. - View Dependent Claims (10, 11, 12, 13, 14, 15)
