With the rapid growth of multimedia content in wireless communication, there is an increasing demand for efficient and error-resilient image and video transmission systems over noisy communication channels. We have developed a general joint source-channel matching scheme for wireless video transmission. This method yields the optimal transmission quality based on the current channel situation while satisfying real-time delay and buffer size constraints. We utilize a parametric model approach which avoids the necessity of having detailed a priori knowledge of the coders, thus making the scheme applicable to a wide variety of source and channel coder pairs. Simulations show that the scheme yields excellent results and works for several different types of source and channel coders.
