Abstract

When a single source of multimedia contents is distributed to multiple reproduction devices, the audio and video contents require synchronous play for multi-channel stereo sound and lip-synchronization. This paper investigates capability of IEEE 802.11 n wireless LANs for providing synchronized services of real-time multimedia traffic. We implement IEEE 1588 Precision Time Protocol in wireless LAN devices to characterize delay jitter and clock synchronization accuracy. The results indicate a strong potential to provide a high fidelity real-time multi-channel multimedia networking service within 430 - microsecond synchronization accuracy at an approximately 80 Mbps streaming rate.
