IPC: H04N19/159
Filed: 2012-09-17
Abstract: The present invention provides a method, apparatus and computer program product for video compression. The technology includes features wherein video content is initially obtained and subsequently separated into picture content and audio content. The picture content is separated into a frame by frame configuration, and a frame type for compression is determined for each of these frames. A frame is filtered and segmented into two or more portions, wherein each portion is indicative of a desired quantization for use during the encoding process. Each portion of the frame is subsequently encoded according to the respective desired quantization. Encoded picture content is generated and includes each encoded portion of a frame and its respective desired quantization. This encoded picture content is interleaved with the encoded audio content, thereby resulting in the compression of the video content. Upon reversal of this sequence of tasks will enable the substantial recreation of the video content for subsequent presentation.

Abstract: The subject invention provides novel plants that are not only resistant to 2,4-D and other phenoxy auxin herbicides, but also to aryloxyphenoxypropionate herbicides.  Heretofore, there was no expectation or suggestion that a plant with both of these advantageous properties could be produced by the introduction of a single gene. The subject invention also includes plants that produce one or more enzymes of the subject invention alone or "stacked"  together with another herbicide resistance gene, preferably a glyphosate. resistance gene, so as to provide broader and more robust weed control, increased treatment flexibility, and improved herbicide resistance management options. More specifically, preferred enzymes and genes for use according to the subject invention are referred to herein as AAD (aryloxyalkanoate dioxygenase) genes and proteins. No a-ketoglutarate-dependent dioxygenase enzyme has previously been reported to have the ability to degrade herbicides of different chemical classes and modes of action. This highly novel discovery is the basis of significant herbicide tolerant crop trait opportunities as well as development of selectable marker technology. The subject invention also includes related methods of controlling weeds. The subject invention enables novel combinations of herbicides to be used in new ways. Furthermore, the subject invention provides novel methods of preventing the formation of, and controlling, weeds that are resistant (or naturally more tolerant) to one or more herbicides such as glyphosate.
