Abstract:

Abstract: Random-access performance is an important requirement for the evaluation of MVC prediction
structure. When random access happens, the system must be able to correctly calculate the decoding path. To
calculate the decoding path, previous studies were mainly concentrated in decoder. In this paper we propose a
new method for decode path calculation based on a reference frame list. The list is updated according to the
actual encoding information. Experimental results show that this method can accurately calculate the needed
frame. Moreover, the method can minimize the number of reference frame and improve the random access
performance.

Key words:  multi-view video coding (MVC), random access, decode path, reference list, joint calculation
