Title:
METHOD OF VIDEO CODING FOR HANDHELD APPARATUS
Document Type and Number:
WIPO Patent Application WO2004068835
Kind Code:
A3
Abstract:
The present invention relates to method of coding blocks of video data for a handheld apparatus comprising a battery. Said method comprising a step of computing a residual error block from the use of a set of prediction functions having different power consumption levels. It also comprises a step of enabling or disabling a prediction function of the set depending on its associated power consumption level for a predetermined level of the battery. It finally comprises a step of selecting a prediction function among a set of enabled prediction functions to code the residual error block.
