Abstract
A method and apparatus for selecting a coding mode are described. For example, the method receives at least one block of a signal to be encoded. The method determines a frame vertical pixel difference in the at least one block and determines a field vertical pixel difference in the at least one block. The method then compares the frame vertical pixel difference with the field vertical pixel difference to determine a first coding mode for the at least one block.
Claims21
A method for selecting a coding mode, comprising:
- receiving at least one block of a signal to be encoded;
- determining a frame vertical pixel difference in said at least one block;
- determining a field vertical pixel difference in said at least one block;
- and
- comparing said frame vertical pixel difference with said field vertical pixel difference to determine a first coding mode for said at least one block.
A computer readable medium having stored thereon instructions that, when executed by a processor, causes the processor to perform a method for selecting a coding mode, comprising:
- receiving at least one block of a signal to be encoded;
- determining a frame vertical pixel difference in said at least one block;
- determining a field vertical pixel difference in said at least one block;
- and
- comparing said frame vertical pixel difference with said field vertical pixel difference to determine a first coding mode for said at least one block.
An apparatus for selecting a coding mode, comprising:
- means for receiving at least one block of a signal to be encoded;
- means for determining a frame vertical pixel difference in said at least one block;
- means for determining a field vertical pixel difference in said at least one block;
- and
- means for comparing said frame vertical pixel difference with said field vertical pixel difference to determine a first coding mode for said at least one block.
A method for selecting a coding mode, comprising:
- receiving at least one block of a signal to be encoded;
- determining a field coding cost of said at least one block in accordance with a field coding mode;
- determining a frame coding cost of said at least one block in accordance with a frame coding mode;
- and
- comparing said frame coding cost with said field coding cost to determine a coding mode for said at least one block.
