Systems and methods for video coding and transmission

Abstract

Disclosed herein are certain embodiments of lattice video coding (LVC) systems and methods (collectively referred to herein also as LVC systems) that provide for adaptive streaming and/or burst error immunity in a video distribution network, such as the Internet or other communication networks. In general, as and explained further below, such LVC systems decompose or partition pictures of one or more segments (e.g., groups of pictures or GOPs) of a video stream into N lattice representations (also referred to herein as latticed representations, latticed or latticed video representations, or the like), where each lattice representation comprises a subset of the pixels of the pre-partitioned picture, and where the collective lattice representations of a given picture comprises the same number of pixels as the pre-partitioned picture. Each resulting lattice representation corresponds to an independently decodable stream (or in some embodiments, dependently decodable streams) that is transmitted in such a manner as to enable dispersion of the corresponding data, hence resulting in temporal data elasticity and immunity to burst errors. Further, with regard to adaptive streaming, the decomposition of the original video into independently decodable streams of lattice representations enables fine-tuning of the bit rate without the necessity of signaling between a receiver and server while obviating the need for additional encoding hardware as is common in multi-bit rate stream implementations.
