摘要

Stereoscopic video multicast over wireless network is a challenging issue due to large bandwidth requirement, limited resource, and heterogeneous user channel conditions. Recently, most existing methods for stereoscopic video multicast employ symmetric video coding that transmits the same video quality for stereo views. In this paper, we propose a novel rate scheduling method for stereoscopic video multicast in WiFi networks through asymmetric video coding to maximize users' perceived video quality. We first formulated rate scheduling problem which has complexity in non-polynomial time subjected to playback time limit, block dependency, and the ratio of asymmetric video quality for stereo views. Then, a novel algorithm is proposed to assign a suitable rate for each frame per layer. Furthermore, we studied the impact of block dependency and asymmetric coding. Experimental results confirm that our approach resulted in promising perceived video quality while outperforming several existing video multicast techniques.
