Abstract

A computer-implemented system and method are described for encoding video. For example, a method according to one embodiment comprises: selecting a tile size for subdividing each image in a sequence of images based on a specified type of encoding algorithm to be used for encoding the tiles, wherein M tiles are encoded for each image, each tile being encoded according to a first encoding format or a second encoding format, each tile having a designated tile location within each image; specifying a rotating pattern to be used for encoding the tiles over a sequence of N images, the rotating pattern comprising encoding only certain tiles of each image using the first encoding format, and rotating the tile locations selected for the first encoding format over the N images to ensure that all M tiles have been encoded according to the first encoding format across the N images; and encoding the sequence of N images using the rotating pattern.

Claims

1. A computer-implemented method for encoding video comprising:

selecting a tile size for subdividing each image in a sequence of images based on a specified type of encoding algorithm to be used for encoding the tiles, wherein M tiles are encoded for each image, each tile being encoded according to a first encoding format or a second encoding format, each tile having a designated tile location within each image;

specifying a rotating pattern to be used for encoding the tiles over a sequence of N images, the rotating pattern comprising encoding only certain tiles of each image using the first encoding format, and rotating the tile locations selected for the first encoding format over the N images to ensure that all M tiles have been encoded according to the first encoding format across the N images; and

encoding the sequence of N images using the rotating pattern.
