Patent ID: 7649937

Claim:
A method of processing a video signal for transmission from a capture device to a remote computing device over a network, wherein at least a portion of the method is performed by the capture device specifically configured to implement the methodology, the method comprising the steps of: capturing a first frame of video data from a video source, the first frame defining a bit-mapped representation comprised of a first plurality of pixels with each pixel including a characteristic component; segmenting the first frame into blocks of pixels; identifying the first frame as the base frame; transmitting the base frame to the remote computing device; capturing a next frame of video data from the video source, the next frame defining a bit-mapped representation comprised of a second plurality of pixels with each pixel including a characteristic component; segmenting the next frame into blocks of pixels; comparing each block in the base frame to a corresponding block in the next frame based on the characteristic component of the pixels within each block; identifying blocks in the next frame that differ from the corresponding blocks in the base frame by a first trigger value; transmitting the identified blocks to the remote computing device; transmitting blocks in the next frame that are adjacent to the identified blocks to the remote computing device.
