Soft Video Delivery by Metadata Reduction over LTE

Abstract

New methods for media delivery, specifically video, have become increasingly important over the past decade. Along with increased user need for video streaming, video is now a majority of the traffic on the internet. In addition, traditionally the conventional design of the end device selecting the appropriate bitrate according to channel quality does not allow graceful degradation of the quality of the received video in a dynamic network environment. In this thesis, a new method is presented through implementing a metadata reduction approach for soft-video delivering over a Long Term Evolution (LTE) network. The goal of this work is to demonstrate that we can obtain superior video transmission over a mobile wireless channel. The design for this system comes in two parts: the soft-video metadata reduction algorithm and the LTE system implemented using National Instruments’ Universal Software Radio Peripheral (USRP) software-defined radio. The experimental data collected validates that the proposed video delivery system outperforms the conventional approach.
