Abstract
Techniques are provided herein to shift at an encoding device a portion of a video sequence by a first predetermined number of pixels horizontally and by a first predetermined number of pixels vertically to produce a shifted first portion of the video sequence. The shifted first portion of the video sequence is encoded to produce a first video description. The portion of the video sequence is shifted by a second predetermined number of pixels horizontally and by a second predetermined number of pixels vertically to produce a shifted second portion of the video sequence. The shifted second portion of the video sequence is encoded to produce a second video description, and the first video description and the second video description are transmitted. The techniques are scalable to shift and encode the portion of the video sequence a plurality of times to produce any number of video descriptions. Similarly, techniques are provided herein to perform such functions in reverse at a decoder.
