End-to-end wireless multimedia transmission system

Abstract

Multimedia transmission over wireless networks is a hot research field, but little work focuses on discussing efficient transmission between wireless terminals. The limited bandwidth of wireless networks and the limited capabilities of wireless terminals are two major problems for the efficient transmission of multimedia flows. We propose an end-to-end wireless multimedia transmission (EEWMT) system that, as well as supporting end-to-end wireless transmission for multimedia flows, provides services to resolve the above two problems. The EEWMT system is mainly made up of three parts: anyDevice, which is a protocol stack working on terminals; a center server, which provides indexing and database services and is responsible for session management; an agent server, which provides data buffering and multimedia transcoding services. Implementation of our system shows that it enhances both the communication efficiency and the content quality.
