Title:
METHOD, APPARATUS AND COMPUTER PROGRAM PRODUCT FOR ADJUSTMENT OF LEAKY FACTOR IN FINE GRANULARITY SCALABILITY ENCODING
Document Type and Number:
WIPO Patent Application WO2008010157
Kind Code:
B1
Abstract:
An improved system and method for effectively reducing prediction drift and improving coding efficiency in scalable video coding. The present invention provides an improved method for determining an offset value that is used to adjust the value of a, a leaky factor for a block of data that includes only zero coefficients at a base layer. In one embodiment of the invention, the offset value is determined based upon information in the enhancement layer at issue instead of the base layer. In another embodiment, information in both the enhancement layer and the base layer of the current frame is used in determining the offset value.
