摘要： Video coding methods and apparatuses are provided that make use of various models and/or modes to significantly improve coding efficiency especially for high/complex motion sequences. The methods and apparatuses take advantage of the temporal and/or spatial correlations that may exist within portions of the frames, e.g., at the Macroblocks level, etc. The methods and apparatuses tend to significantly reduce the amount of data required for encoding motion information while retaining or even improving video image quality.

摘要： Improved video coding is described to encode video data within a sequence of video frames. To this end, at least a portion of a reference frame is encoded to include motion information associated with the portion of the reference frame. At least a portion of a predictable frame that includes video data predictively correlated to said portion of said reference frame is defined based on the motion information. At least said portion of the predictable frame is encoded without including corresponding motion information and including mode identifying data. The mode identifying data indicate that the encoded portion of the predictable frame can be directly derived using at least the motion information associated with the portion of the reference frame.

摘要： Methods and apparatuses are provided relating to the encoding of data, such as, e.g., images, video, etc. For example, certain methods include processing at least a portion of data using a plurality of different quantization functions to produce a plurality of corresponding quantized portions of data, and selectively outputting one of the quantized portions of data based on at least one threshold value. The method may also include dividing initial data into a plurality of portions and classifying the portion of data based on at least one classification characteristic. Here, for example, there may be a threshold value that is associated with the classification characteristic. Additional syntax may be adopted to enable considerably higher compression efficiency by allowing several alternative motion prediction cases. A high efficiency time stamp independent Direct Mode is also provided which considers spatial motion vector prediction as well with stationary temporal predictors.
