Abstract:
This paper analyzes how the frame based video codec structure undermines the real-time performance of audio codec and communication module in embedded multimedia communication platform, and proposes a design solution based on finite state machine(FSM) using state converting graph. The experimental results demonstrate that the FSM control flow improves the system real-time performance obviously.
