Abstract
Video compression algorithms typically represent visual information by a combination of motion and texture data. Motion data describes the temporal relationship between the content of a frame and that of a previous frame. This invention describes a method and apparatus for efficiently encoding motion data, particularly in the presence of horizontal and/or vertical motion boundaries.
Claims20
A prediction generator comprising:
- a memory for storing a first prediction and a second prediction;
- a comparator coupled to the memory to compare the first prediction and the second prediction;
- and
- a controller coupled to the comparator to update the second prediction while the first and second predictions are equal and a stop condition is not satisfied.
A method comprising:
- setting first and second predictions;
- comparing the first and second predictions;
- and
- updating the second prediction if the first and second predictions are equal and a stop condition is not satisfied.
An article of manufacture having one or more non-transitory computer readable storage media having instructions stored thereon which, when executed by a system, cause the system to perform a method comprising:
- setting first and second predictions;
- comparing the first and second predictions;
- and
- updating the second prediction if the first and second predictions are equal and a stop condition is not satisfied.
