Abstract

Precise inter-media synchronization of transported media among multiple sessions is an important issue in high-quality media-based collaboration environments. Especially, well known uncompressed HD-based media requires extremely tight inter-media synchronization. In this paper, by employing localized clock synchronization, we propose precise inter-media synchronization scheme for multiple session-based uncompressed HD media transport. To avoid delayed clock synchronization message, minimum offset selection and filtering schemes are used for the proposed scheme. Moreover, to reduce receiver's buffer overburdening, multiple senders share receiver's buffer overhead by using frame-send-interval adjustment. These two approaches can make network-adaptive precise inter-media synchronization. From the simulation results, we verify that the proposed synchronization scheme satisfies synchronization requirements with high accuracy.
