Method and apparatus for representation of video and audio signals on a low-resolution display

摘要

The method for the representation of video and audio signals on a low-resolution display panel, which includes the steps of: scaling the video or audio frame to fit the display panel, quantization of the video or audio signals to predetermined level values, temporal representation of video data by using the pulse density modulation, sending the signal pulses to the display panel. In further aspect the step of temporal representation contains the anti-flickering signal manipulation technique incorporating maximization of separation of the pulses during the pulse density modulation.

1. A method for modulation of a video signal for display on a low-resolution display, the method comprising:
scaling the video signal to fit the low-resolution display; quantizing the video signal to predetermined level values; generating a pulse density modulated representation of the scaled and quantized video signal; altering the scaled and quantized video signal to result in an increased temporal distance between each two consecutive pulses in the pulse density modulated representation to decrease flickering; and sending the pulse density modulated representation of the scaled and quantized video signal directly to a display buffer for output of the pulse density modulated representation of the scaled and quantized video signal to the low-resolution display.
