1. A computer-implemented method comprising, by a source computer:
generating a first down-sampled frame of an input image by sampling the input image according to a first sampling pattern, wherein the first down-sampled frame comprises a first subset of pixels of a set of pixels in the input image;
generating a first encoded down-sampled frame by encoding the first down-sampled frame;
transmitting the first encoded down-sampled frame of the input image to a recipient device for display, wherein the recipient device uses the first encoded down-sampled frame of the input image to generate a first output frame for display by decoding and up-sampling the first encoded down-sampled frame;
responsive to transmitting the first encoded down-sampled frame of the input image to the recipient device for display, generating at the source computer, a second down-sampled frame of the input image by sampling the input image according to a second sampling pattern;
generating a second encoded down-sampled frame by encoding the second down-sampled frame; and
transmitting the second encoded down-sampled frame of the input image to the recipient device for display, wherein the recipient device uses the first encoded down-sampled frame and the second encoded down-sampled frame to generate a second output frame for display in accordance with the first sampling pattern and the second sampling pattern.
