1. A method, comprising: performing, by a computing device: receiving image data for a first image in a sequence of images, wherein each image in the sequence comprises a plurality of image tiles; transmitting the image data for the first image, wherein said transmitting comprises transmitting image data for at least some of the first image's plurality of tiles using lossy compression due to resource constraints; receiving image data for a subsequent image in the sequence of images; determining that the image data for at least some of the subsequent image's plurality of tiles does not change more than a predetermined amount relative to image data for corresponding tiles of the first image; and transmitting the image data for the subsequent image in a manner sufficient to create lossless versions of tiles for which lossily compressed data was previously sent.
