Abstract:
A method of fast mode decision of an enhancement layer using a bitrate-distortion cost in an SVC encoder includes: calculating a bitrate-distortion cost for a current macro block of an enhancement layer and a bitrate-distortion cost for a previous macro-block of the current macro block of an enhancement layer based on an optimal motion mode and an motion vector for a macro block of a base layer of a current frame; correcting the bitrate-distortion cost for the previous macro block calculated at the calculating by a correction value for reflecting relationship with the previous frame to calculate a final bitrate-distortion cost for the previous macro block; and comparing the bitrate-distortion cost for the current macro block calculated at the calculating with the final bitrate-distortion cost calculated at the correcting and selecting a motion mode that will be removed from the current macro block according to the comparison result.
