Abstract
Video encoding methods and video encoders that provide improved performance while reducing power consumption. In one aspect, a video encoding method comprises the steps of outputting a parameter for a slice of a current frame, wherein the slice comprises a plurality of macroblocks, processing the slice by consecutively encoding and decoding each macroblock of the slice in response to the parameter, and outputting an interrupt signal for the slice The parameter preferably comprises an address of the first macroblock of the slice, an address of a search area in a previous frame, the search area corresponding to a current macroblock in a current frame, and a number of macroblocks comprising the slice.

A video encoding method, comprising the steps of:
- outputting a parameter for a slice of a current frame, wherein the slice comprises a plurality of macroblocks, wherein the parameter comprises an address of a first macroblock of the slice, an address of a search area in a previous frame, the search area corresponding to a current macroblock in a current frame, and a number of macroblocks comprising the slice;
- processing the slice by consecutively encoding and decoding each macroblock of the slice in response to the parameter;
- and
- outputting an interrupt signal for the slice.
A video encoder, comprising:
- a main control unit for outputting a parameter for a slice of a current frame, wherein the slice comprise a plurality of macroblocks, wherein the parameter comprises an address of a first macroblock of the slice, an address of a search area in a previous frame, the search area corresponding to a current macroblock in a current frame, and a number of macroblocks of the slice;
- and
- a motion estimator for consecutively encoding and decoding each macroblock of the slice in response to the parameter and outputting an interrupt signal to the main control unit when the encoding and decoding for the slice is complete.
A video encoding method, comprising the steps of:
- outputting a parameter for a slice of a current frame, wherein the slice comprises a plurality of macroblocks;
- processing the slice by consecutively encoding and decoding each macroblock of the slice in response to the parameter;
- and
- outputting an interrupt signal when the encoding and decoding for the slice is complete, wherein the interrupt signal indicates a point in time when encoding and decoding of each macroblock of the slice has been completed.
