“…We use Li's model to evaluate the effects of the generic improvements for existing fast mode decision models. Since in literature Li is referred by other models refer, Li can be seen as a common ground for comparison, e.g in [6] their reported time saving is 7% lower than Li, while for the combination of their model with Li, the time saving is improved with 11% compared to Li.…”

“…Li et al [2] suggest two schemes for spatial/quality scalability and temporal scalability, but the two schemes cannot be supported simultaneously. A fast mode decision scheme proposed by Kim et al [3] can be supported separately in spatial scalability or quality scalability. Kim et al [4] propose a fast mode decision for full SVC based on block complexity function but the performance is not sufficient.…”

To provide network friendly scalability, scalable video coding (SVC) has been finalized as an H.264/AVC scalable extension. Because SVC supports a inter layer prediction scheme to determine the best coding mode in an enhancement layer, it achieves high coding efficiency but increases computational complexity. To reduce the computational complexity, we propose a fast and efficient mode decision scheme for enhancement layer using the coded block pattern for 16×16 mode of the current and previous pictures. Experimental results show that the proposed algorithm reduces the processing time about 41.30% with negligible loss in coding efficiency.

“…Through context-adaptive mode decision, Lin et al [8] performed coarse-grain quality scalability (CGS) and temporal scalability with less computation. Kim et al [9] predicted coding mode using the weighted result of the co-located MB and its neighboring MBs in BL. Lee et al [10] employed the bipredictive zero motion to accelerate mode decision process.…”

This paper presents a strategy that efficiently allocates the limited resource and still maintains the coding performance for the spatial scalability of H.264/SVC. An integrated computation-scalable algorithm is proposed on the basis of priority-based mode decision (PBMD) and activitybased motion estimation (ABME). The rate-distortion cost (RD-cost) of base layer is utilized as the priority to decide the mode in the enhancement layer, and the motion vector difference (MVD) in the base layer is employed to determine the search range as well. Through the proposed approach, computation complexity of the enhancement layer could be reduced efficiently and well allocated. A fast algorithm with early termination mechanism is also proposed in this paper. Experimental results demonstrate that the various ratedistortion and time-saving performances with computation scalability are realized.
