Optimizing user Quality of Experience (QoE) for live video streaming remains a long-standing challenge. The Bitrate Control Algorithm (BCA) plays a crucial role in shaping user QoE. Recent advancements have seen RL-based algorithms overtake traditional ...

Live video streaming has grown dramatically in recent years. A key challenge is achieving high video quality of experience (QoE) in low-rate networks. To tackle this problem, recent streaming approaches strategically drop video frames, thus reducing the ...

Fueled by the rapid advances in high-speed mobile networks, live video streaming has seen explosive growth in recent years and many DASH-based bitrate adaptive streaming algorithms were specifically proposed for low-latency video delivery. However, our ...

Viewport prediction plays a crucial role in live 360° video streaming as it determines which tiles should be prefetched in high quality, thereby significantly impacting the user experience. However, the current approach to viewport prediction, which ...

Content Distribution Networks (CDN) and HTTP Adaptive Streaming (HAS) are considered the principal video delivery technologies over the Internet. Despite the wide usage of these technologies, designing cost-effective, scalable, and flexible ...

Transmission of live media is becoming increasingly popular in entertainment. Despite peer-to-peer protocols being popular for transmission of large data files, they are notably absent from the application of live content distribution. A protocol named ...

Live video streaming is widely embraced in video services, and its applications have attracted much attention in recent years. The increased number of users demanding high quality (e.g., 4K resolution) live videos increases the bandwidth utilization in ...

Virtual reality (VR) streaming can provide immersive video viewing experience to the end users but with huge bandwidth consumption. Recent research has adopted selective streaming to address the bandwidth challenge, which predicts and streams the user's ...

The outbreak of COVID-19 has led to a sharp transition from offline to online education in many countries and areas. This transition heightens the intensity of existing challenges of online education, such as student attendance and education equality. ...

Large-scale events pose severe challenges to live video streaming service providers, who need to cope with high, peaking viewer numbers and the resulting fluctuating resource demands, keeping high levels of Quality of Experience (QoE) to avoid end-user ...

Video players employ adaptive bitrate algorithms in video-on-demand (VoD) scenarios to improve user-perceived quality of experience (QoE), whereas performance will obviously decline in live video streaming scenarios. To this end, we propose a novel deep ...

Live video streaming delivery over Dynamic Adaptive Video Streaming (DASH) is challenging as it requires low end-to-end latency, is more prone to stall, and the receiver has to decide online which representation at which bitrate to download and whether ...

With the growing popularity and prosperity of living streaming applications, it is naturally confronting users' quality of experience (QoE) degradation issues especially under dynamic environments arised from nonnegligible factors such as high latency ...

In this paper, we introduce a continuous bitrate control and latency control model for the Live Video Streaming Challenge. Our model is based on Deep Deterministic Policy Gradient, popular on continuous control tasks. Simultaneously, it can take a fine-...

Live streaming applications are becoming increasingly popular recently, and it exposes new technical challenges compared to regular video streaming. High video quality and low latency are two main requirements in live streaming scenarios. A live ...

Real time video streaming solutions have seen an exponential growth over the past years, with their main limit being the high costs associated to the amount of outgoing bandwidth required to serve high quality content to millions of users. This demo ...

Personalized live video streaming is an increasingly popular technology that allows a broadcaster to share videos in real time with worldwide viewers. Compared to video-on-demand (VOD) streaming, experimenting with personalized live video streaming is ...

The regional activation is an important issue for regional areas. In order to resolve this issue, we propose a live video streaming service for regional activation with the network virtualization technology. In our proposed service, a live video of each ...

This paper explores different visual interfaces for sharing comments on a social live video streaming platforms. So far, comments are displayed separately from the video making it hard to relate the comments to event in the video. In this work we ...
