    ABSTRACT: In this paper, we present a novel adaptive GOP structure(AGS) for H.264/SVC. Proposed method adaptively defines the GOP structure by analyzing the input sequence characters. The accumulated difference of luminance pixel components is utilized to set a threshold for adaptive GOP size definition. Another scene change detection method is also proposed to reorganize the GOP structure. Different from previous AGS methods, the proposed method concentrates on the coding efficiency improvement on the basis of the Hierarchical B-picture structure. The simulation results show that proposed AGS method can improve up to 0.2 dB of PSNR compared with fixed size GOP methods.
