SYSTEM AND METHOD FOR DIGITAL VIDEO FRAME SCANNING AND STREAMING

摘要

A computer system executable method for use in transmitting digital video stream from a transmitting device to at least one receiving device. The method includes copying VRAM at time (t) from a transmitting digital device to create memory array Aij(t) (12), compressing Aij(t) data (14), sending compressed Aij(t) data to receiving digital device (16), copying VRAM at time (t+1) to create memory array Aij(t+1) (18), scanning and comparing memory array Aij(t) and memory array Aij(t+1) (20), creating memory array XORij(t+1) and coding the pixels to indicate changed and unchanged pixels (22), compressing XORij(t+1) data (24), and sending compressed XORij(t+1) data to receiving digital device (26). The method may continue (28) with the next frame (18).
