Abstract:
A method for processing video data and graphics data, the method comprises the steps of:a) retrieving the graphics data at a first clock rate to produce retrieved graphics data;b) retrieving the video data at the first clock rate to produce retrieved video data;c) sampling the retrieved video data at a second clock rate to produce sampled video data, wherein the second clock rate is greater than the first clock rate;d) filtering the sampled video data to produce filtered video data, wherein the filtering attenuates high frequency components of the sampled video data;e) mixing, based on a control signal, the retrieved graphics data with the filtered video data to produce mixed data; andf) buffering the graphics data and retrieving the graphics data from a buffer at the second clock rate to produce the retrieved graphics data.
