Abstract
In current spatial scalable video coding (SVC) scheme, some additional tools and more modes are provided in order to improve the coding efficiency for the enhancement layer, but the drawback is that much more coding time is required. In this paper, we propose two schemes from different perspectives to reduce the coding time. In scheme 1, part of the motion estimation (ME) processes are skipped while scheme 2 gives a fast mode decision algorithm for the enhancement layer coding. The experimental results show that for scheme 1, up to 24% time saving can be achieved while for scheme 2, more than 30% time saving can always be achieved and meanwhile the coding efficiency can be preserved well. Moreover, the two proposed schemes can be combined together to further reduce the coding time.
