Abstract:

By exploiting the macroblock correlation in spatial and temporal scalable video coding, a fast mode decision algorithm was proposed. It chooses a part of the used search modes from the co-located reference macroblocks to compose the candidate group for the current macroblock. This will extremely reduce the calculation amount of motion estimation in enhancement layers. According to the experimental results, this algorithm decreases the encoding time with the negligible coding loss and bit-rate increases.

Key words: communication, scalable video coding, fast mode decision, adaptive inter-layer prediction
