摘要：
A method, apparatus and system for signal modulation. A plurality of pixels are selected in a pattern such that a first pixel group of the plurality of pixels is unpaired with a second pixel group of the plurality of pixels throughout the pattern in a portion of a video signal. The intensity of the plurality of the pixels is altered at a constant magnitude in the portion of the video signal pursuant to the pattern in a substantially invisible way.
