We propose a new resource management scheme for multiple video stream transmission (digital TV and digital video) in a wireless environment, where document file and packetized voice are also transmitted. The proposed scheme performs an adaptive transmission and dynamic frequency resource assignment. It determines the transmission parameters, such as modulation format, FEC code rate and the number of time slots per frame, according to the error sensitivities, the required bit rates for the transmitted packets, and the channel state. We analyze the MSE performance of the decoded video and the bit error rate performance of the data traffic by computer simulation. The simulation results show that the proposed scheme gives much better performance than the conventional uniform resource assignment scheme. It is capable of improving the total QoS (quality of service) of two or more video streams and non-stream traffic with efficient radio resource utilization.
