Adaptive rate control scheme to improve QoS of multimedia streaming application

Abstract

This paper presents an adaptive rate control scheme for streaming-based content sharing service which delivers multimedia contents from a user device to another device or seamlessly redirect streaming service across heterogeneous user devices. In proposed scheme, a streaming server adjusts video quality level according to the network and client status. Our scheme is different from other rate control schemes because the video quality at the server is decided not only based on the available bandwidth, but also on the device characteristics and bandwidth requirement at the access network. Through the simulation, we prove that our scheme improves the network stability and quality of streaming service by appropriately adjusting the quality of video stream.

Adaptive Rate Control Scheme for Streaming-based Content Sharing Service

“…This requires three times higher bandwidth at the access network. Also, the multimedia streaming service has stringent timing requirements for video playback because a server transfers the multimedia content to the client as a continuous stream and the client consumes the data as it arrives [2]. This requirement imposes bandwidth, delay and loss demands on the underlying network that is responsible for delivering the data.…”
