With the rapid development of video coding technology, all kinds of video coding standards have been advanced in recent years with a variety of different and complex algorithms. They share common and/or similar coding tools, yet there is currently no explicit way to exploit such commonalities at the level of specifications or implementations. Reconfigurable video coding (RVC) is to develop a video coding standard that overcomes many shortcomings of current standardization and specification process by updating and progressively incrementing a modular library of components. In this paper, a hybrid decoder reconfiguration is instantiated in the RVC framework by grouping the coding tools from AVS-P7 and MPEG-4/AVC. Experimental results show that compared with MPEG-4/AVC baseline profile, the reconfigurable coding system reduces the computational complexity and guarantees the coding performance at low bit rate. Moreover, it enriches the RVC video tool library (VTL) by introducing the coding tools of AVS-P7, and also verifies the flexibility and re-configurability of RVC framework to meet the needs of different applications.
