Hierarchical video compression supporting selective delivery of two-dimensional and three-dimensional video content

Abstract

Systems, methods and apparatuses are described herein for encoding a plurality of video frame sequences, wherein each video frame sequence corresponds to a different perspective view of the same subject matter. In accordance with various embodiments, the encoding is performed in a hierarchical manner that leverages referencing between frames of different ones of the video frame sequences (so-called “external referencing”), but that also allows for encoded representations of only a subset of the video frame sequences to be provided when less than all sequences are required to support a particular viewing mode of a display system that is capable of displaying the subject matter in a two-dimensional mode, a three-dimensional mode, or a multi-view three-dimensional mode.

Problems solved by technology

Recently, there has been a substantial increase in the types and amount of digital video content available to consumers and a concomitant increase in demand for such content.

Even though video compression techniques such as those mentioned above can be used to reduce the amount of data needed to represent digital video content, there is still a finite amount of bandwidth available on networks that transmit digital video content and there is also a finite amount of
