Abstract:
Multiple description codes are designed for multiple path video streaming with channel diversities and an efficient MDC technique based on the applied spatial domain processing features. In this paper, we investigate the performance of multi-path video streaming using a multiple description coding (MDC) technique, especially the impacts of several codec variables, such as different lengths of the Group of Pictures (GOP), and the different startup times of I-frame in each independent MDC sub-streams. The overall performance of the system is evaluated by the frame dropout rate, which indicates the probability of playing back frozen frames of the reconstructed video at the receiver devices. To address dynamic channel conditions for video transmissions, we propose an adaptive coding technique by adjusting the GOP lengths according to the channel condition and combinatorial mathematics optimization in length of GOP adjustment. Different approaches, such as sub-dividing GOPs for a single stream and multiple sub-streams, and an adaptive MDC video streaming system, are examined in this paper.
