Abstract
A system for, and method of, entropy coding. In one embodiment, the system includes: (1) a memory configured to contained initialized accumulated statistics coding variable values and (2) a processor configured to employ the initialized accumulated statistics coding variable values to context-adaptive encode multiple symbols until an accumulated statistics update condition occurs and updating and store the accumulated statistics coding variable values in the memory only upon occurrence of the accumulated statistics update condition.
Claims17
A system for entropy coding, comprising:
- a memory configured to contain initialized accumulated statistics coding variable values;
- a processor configured to employ said initialized accumulated statistics coding variable values to context-adaptive encode multiple symbols until an accumulated statistics update condition occurs and updating and store said accumulated statistics coding variable values in said memory only upon occurrence of said accumulated statistics update condition.
A method of entropy coding, comprising:
- initializing accumulated statistics coding variable values;
- context-adaptive encoding multiple symbols using said accumulated statistics coding variable values until an accumulated statistics update condition occurs;
- and
- updating said accumulated statistics coding variable values only upon occurrence of said accumulated statistics update condition.
A method of accumulated statistics-based entropy coding, comprising:
- (a) initializing accumulated statistics coding variable values;
- (b) context-adaptive encoding a symbol using current accumulated statistics variable values;
- (c) when an update condition occurs, updating said accumulated statistics variable values;
- and
- (d) repeating steps (b)-(c) until all symbols are encoded.
A method of accumulated statistics-based entropy coding, comprising the steps of:
- (a) performing a core coding process of an accumulated statistics-based entropy coding scheme;
- (b) when a discrete point occurs, performing an updating process, otherwise do not update;
- and
- (c) repeating steps (a)-(b) until a coding is complete.
