A decimation system and method for providing video data to a PIG window in an EPG environment. In one embodiment, the system includes an EPG system having a picture in guide window, a tuner to generate a video signal, a decoder coupled to the tuner to receive the video signal and generate pixels based on the received signal, a PIG generator coupled to the decoder that performs a real time weighted averaging to select a subset of the pixels; and a display generator to display the subset of the pixels in the PIG window on a monitor.
