Dynamic Adaptive Streaming Over HTTP (DASH)-Comprehensive Study and Rate Adaptation Performance Analysis

摘要

Streaming enables the users to view real time multimedia content on-the-go at anywhere, any time. With the revolution of internet and increasing bandwidth support, streaming usage grows more and more. Conventional Streaming Delivery Method widely uses Real-Time Transport Protocol (RTP) over User Datagram Protocol (UDP) and Hypertext Transport Protocol (HTTP), Real time Messaging Protocol (RTMP) over Transport Control Protocol (TCP). The quality of service is a major concern in the increasing network traffic and high user demand. An adaptive HTTP streaming is the emerging technique provides advancement in terms of quality and user experience compare to the traditional streaming techniques. It dynamically selects the media bit rate based on the network variation and processing capability to ensure the best quality of service to the consumer. In this study, researchers focus on end to end study of MPEG Dynamic Adaptive Streaming over HTTP (DASH) Method with gstreamer streaming client. The rate adaptation behavior of the DASH Model experimentally evaluated with internet, test bed environment under different network conditions and the results are analyzed.
