Title: Improved Refinement Coefficients' Coding In Scalable H.264
Author: Panchal, Rahul
Abstract: This thesis proposes to replace the adaptation used to select VLC table for coding of the refinement coefficient by signaling to the decoder which table should be used for which macroblock type (Inter or Intra) in scalable H.264. This part of the proposal aims at reducing decoder complexity and ensuring proper table selection when both macroblock types are present within one slice. The contribution further proposes to extend the method used in SVC to increase coding efficiency of CABAC refinement coefficient coding to "VLC" refinement coefficients coding. All the coding tools are integrated into JSVM_7_10 and the performance is tested. The proposed changes mainly affect Intra coded slices and for these slices the improvements are in the range of 3-7% for 3 FGS layers.
