Abstract:
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.
