US 7,606,310 B1 · Video compression and encoding method

Abstract

A method of compressing video data having at least one frame having at least one block and each block having an array of pixels is provided. The method transforms the pixels of each block into coefficients and creates an optimal transmission order of the coefficients. The method also optimizes the speed of processing compressed video data by partitioning the data bitstream and coding each partition independently. The method also predicts fractional pixel motion by selecting an interpolation method for each given plurality or block of pixels depending upon at least one metric related to each given block and varies the method from block to block. The method also enhances error recovery for a current frame using a frame prior to the frame immediately before the current frame as the only reference frame for lessening quality loss during data transmission. Enhanced motion vector coding is also provided.

Dependent claims

A method for encoding motion vectors in video compression, comprising the steps of:

Subdividing an image into a set of partitions, and for a given partition;
a) Examining motion vectors of partitions surrounding said given partition in said image that have been encoded prior to said given partition
b) Counting how many times each motion vector appears in the partitions surrounding said given partition and producing a plurality of tallies of each of said motion vectors;
and
c) Using a subset of said tallies to determine which motion vector is re-used as a reference to encode a motion vector of said given partition.
