A Queue‐Aware Extension to BBR for Low‐Latency Transport in Video Applications
This work addresses a long‐standing challenge in congestion control for real‐time video delivery: how to reliably maintain low latency in highly dynamic networks without sacrificing throughput. We explicitly model the excess queue incurred during bandwidth probing as a “queue debt” and then systematically “repay” this debt in subsequent phases by ...

Why is Multimedia Quality of Experience Assessment a Challenging Problem?
Quality of experience (QoE) assessment occupies a key role in various multimedia networks and applications. Recently, large efforts have been devoted to devise objective QoE metrics that correlate with perceived subjective measurements.

Layer-Assisted Video Quality Adaptation for Improving QoE in Wireless Networks
HTTP adaptive streaming (HAS) is a state-of-the-art technology for video streaming. Optimal adaptive streaming schemes should be designed to maximize the quality of experience (QoE) in network environments with unstable bandwidths such as wireless ...

This article presents an adaptive unmanned aerial vehicle video streaming framework in which captured video is encoded at multiple quality levels and protected using Luby transform (LT) coding before transmission over a wireless channel to a base station. At the receiver, LT decoding and latency monitoring are used to assess delivery performance, while

Versatile Video Coding Using Discrete Wavelet Transforms and Histogram Analysis
This paper proposes a novel framework that combines discrete wavelet transforms (DWT) and histogram analysis to optimise the prediction directions in VVC. Through selective reduction of prediction directions based on dominant texture orientation and minimising residual energy, the frame‐work achieves enhanced computational efficiency while maintaining ...

Adaptive Bitrate Streaming With Video Quality Enhancement
We bring the new factor, DVQE sensitivity, into the bitrate selection for the QoE improvement of adaptive video streaming. We develop DSABR, which selects chunk bitrate with high DVQE sensitivity to improve video quality as well as reduce bandwidth usage, thereby achieving efficient performance in bandwidth‐constrained network environments.
