Abstract
A method and apparatus for communicating image data. In one embodiment, the method comprises transmitting, by a computer comprising at least one processor, (i) an initial encoding of a first image instance of a first spatial tile in a sequence of image frames followed by (ii) an initial encoding of a second image instance of the first spatial tile; transmitting, by the computer, an encoding indicative of a perfect match between pixel values of a first image instance of a second spatial tile in the sequence and the first image instance of the first spatial tile; and transmitting, by the computer, an initial encoding of a second image instance of the second spatial tile based on receiving an indication of an absence of a decoding of the encoding of the first image instance of the first spatial tile.
