Abstract
A video encoder and corresponding method are provided for mixed inter/intra encoding of a macroblock having a plurality of partitions, where the encoder includes a reference picture weighting applicator coupled with a reference picture weighting factor unit for assigning weighting factors corresponding to each of the inter and intra coded partitions, respectively; and the corresponding method for encoding a macroblock with several partitions includes inter-coding at least one partition and intra-coding at least a second partition.
Claims23
A method for encoding a macroblock having a plurality of partitions, the method comprising:
- inter-coding at least one of said plurality of partitions;
- and
- intra-coding at least a second of said plurality of partitions wherein said intra-coding comprises providing a reference picture index that is associated with a weighting factor of zero.
A method for encoding a macroblock having at least one partition, the method comprising non-predictively intra-coding the at least one partition by providing a reference picture index that is associated with a weighting factor of zero, wherein said non-predictive intra-coding is performed within a weighted prediction encoding mode by using a weighting factor of zero with a weighted prediction tool from at least one of the Main and Extended profiles of the JVT standard.
A video encoder for mixed inter/intra encoding of a macroblock having a plurality of partitions, the encoder comprising:
- a reference picture weighting applicator;
- and
- a reference picture weighting factor unit in signal communication with the reference picture weighting applicator for assigning weighting factors corresponding to each of the mixed inter and intra coded partitions, respectively.
An apparatus for encoding a macroblock having a plurality of partitions comprising:
- means for inter-coding at least one of said plurality of partitions;
- and
- means for intra-coding at least a second of said plurality of partitions,
- wherein said means for intra-coding utilizes a reference picture index that is associated with a weighting factor of zero.
