Abstract
This paper studies a coding control method for software real-time video communication. Since CPU performance is greatly improved recently, video codec system can be implemented by software. It is expected that video codec software is widely spread and installed on many kinds of computers. In case that performance difference between terminals is so large, the PC with lower performance may have some trouble due to bitstream encoded with high frame rate by the PC with higher performance. In this paper, a coding control method considering computer's performance is studied.
