Abstract
An apparatus, method and system for improving or otherwise affecting the picture produced from a video signal. The apparatus preferably includes a video signal receiver, a circuit that decodes picture parameter correction information from a received video signal, and a circuit that processes a received video signal based on decoded picture parameter correction information. The correction information is preferably located in the vertical blanking interval of the received video signal. The method includes encoding picture parameter correction information into a vertical blanking interval of a video signal.
Claims23
An apparatus for improving or otherwise affecting the picture produced from a video signal, comprising:
- a circuit that receives a video signal;
- a circuit that extracts from a received video signal a digital picture parameter adjustment code that is representative of at least a first amount by which to adjust a first picture parameter and a second amount by which to adjust a second picture parameter, said first and second picture parameters being from the group of picture parameters including color, noise reduction, intensity, black level and clarity picture parameters;
- a circuit coupled to said video signal receiving circuit and said extraction circuit that adjusts the value of the first picture parameter of a received video signal by the first amount and that adjusts the value of the second picture parameter of that received video signal by the second amount;
- and
- an output that outputs a received video signal so adjusted;
- wherein said first and said second picture parameters are different picture parameters.
