Patent ID: 8644374

Claim:
A method comprising: at an encoding device, shifting 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; discarding first portion pixels that have been shifted out of the shifted first portion of the video sequence; padding the shifted first portion opposite a discarded first portion pixels side of the video sequence with pixels of known characteristics when either the first predetermined number of pixels horizontally or the first predetermined number of pixels vertically is not equal to zero; encoding the shifted first portion of the video sequence to produce a first video description; determining a first transmission bandwidth requirement for transmitting the first video description; quantizing the first video description with a first set of weights to meet the first transmission bandwidth requirement; shifting the portion of the video sequence 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; discarding second portion pixels that have been shifted out of the shifted second portion of the video sequence; padding the shifted second portion opposite a discarded second portion pixel side of the video sequence with pixels of known characteristics prior to encoding the shifted second portion of the video sequence to produce a second video description; encoding the shifted second portion of the video sequence to produce the second video description; determining a second transmission bandwidth requirement for transmitting the second video description; quantizing the second video description with a second set of weights to meet the second transmission bandwidth requirement; and transmitting the first video description and the second video description.
