Abstract
A method of making a video stream from a plurality of viewports within large format imagery is described. In one embodiment, the method includes retrieving a plurality of viewports within a plurality of images, each image being arranged as a matrix of tiles, from a file container. The method includes inputting parameters including an identification of a plurality of records where the plurality of images containing the plurality of viewports are stored, an origin of each of the plurality of viewports and a pixel width and a pixel height of each of the plurality viewports. The method further includes requesting the plurality of viewports from the file container using the parameters; and reading data of each of the plurality of viewports starting from the origin of each or the plurality of viewports. The method may further include arranging the plurality of viewports as a video codestream of a group of pictures.
