Abstract
A method and apparatus for coding positions of data such as coefficients are described. In one embodiment, the method comprises coding data in a vector of data based on indications of whether the data is zero or non-zero identified using a tree data structure and producing a bit stream based on coded data.
Claims37
A method comprising:
- coding data in a vector of data based on indications of whether the data is zero or non-zero identified using a tree data structure;
- and
- producing a bit stream based on coded data.
An apparatus for encoding coefficients comprising:
- an input to receive a vector of data;
- and
- an entropy encoder coupled to the input to code data in the vector of data based on indications of whether the data is zero or non-zero identified using a tree data structure.
An article of manufacture having one or more recordable media storing instructions which, when executed by a system, cause the system to perform a method comprising:
- coding data in a vector of data based on indications of whether the data is zero or non-zero identified using a tree data structure;
- and
- producing a bit stream based on coded data.
A method comprising:
- receiving a bit stream;
- and
- decoding the bit stream to produce a vector of decoded data based on indications of whether the data is zero or non-zero as identified by a tree data structure.
An apparatus for decoding quantized coefficients comprising:
- an input to receive a bitstream;
- and
- an entropy decoder coupled to the input to produce a vector of decoded data based on indications of whether the data is zero or non-zero as identified by a tree data structure.
An article of manufacture having one or more recordable media storing instructions which, when executed by a system, cause the system to perform a method comprising:
- decoding the bit stream to produce a vector of decoded data based on indications of whether the data is zero or non-zero as identified by a tree data structure.
