Abstract:
An electronic program guide (EPG) system including a picture in guide (PIG) window comprising:a monitor having a display screen; 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 generate a subset of the pixels as a line of pixels is generated by the decoder; a memory to buffer the generated pixels; and a display generator to display the subset of the pixels in the PIG window on the display screen, wherein the memory buffers 3 adjacent pixels in a 3Ã—3 sliding window for the current line and the previous two lines, and the PIG generator performs the real time weighted averaging to select one pixel out of the nine pixels from the sliding window.
