Joint preloading and bitrate adaptation for short video streaming
(2023)Short videos have become one of the most popular content mobile users consume nowadays. However, unlike traditional videos, users watch many short videos each time and frequently skip those not of their interest. Not taking ... -
QoE-aware video streaming over HTTP and software defined networking
(2019-08-19)Due to the increase in video streaming traffic over the Internet, more innovative methods are in demand for improving both Quality of Experience (QoE) of users and Quality of Service (QoS) of providers. In recent years, ... -
An LSTM-based Approach for Overall Quality Prediction in HTTP Adaptive Streaming
(2019-04-29)HTTP Adaptive Streaming (HAS) has become a popular solution for multimedia delivery nowadays. In HAS, video quality is generally varying in each streaming session. Therefore, a key question in HTTP Adaptive Streaming is ... -
A Subjective study on user perception aspects in virtual reality
(2019-08-01)Three hundred and sixty degree video is becoming more and more popular on the Internet. By using a Head-Mounted Display, 360-degree video can render a Virtual Reality (VR) environment. However, it is still a big challenge ... -
An Efficient QoE-Aware HTTP Adaptive Streaming over Software Defined Networking
(2020-10)Due to the increase in video streaming traffic over the Internet, more innovative methods are in demand for improving both Quality of Experience (QoE) of users and Quality of Service (QoS) of providers. In recent years, ... -
Scalable 360 Video Streaming using HTTP/2
(2019-09)360-degree video is the main content type of Virtual Reality, providing users with immersive viewing experience. In this paper, we propose a novel adaptation method for 360-degree video streaming over HTTP/2, which can ... -
A weighted viewport quality metric for omnidirectional images
(2020)Thanks to the ability to bring immersive experiences to users, Virtual Reality (VR) technologies have been gaining popularity in recent years. A key component in VR systems is omnidirectional content, which can provide ... -
Retina-based quality assessment of tile-coded 360-degree videos
(2022-06-21)Nowadays, omnidirectional content, which delivers 360-degree views of scenes, is a significant aspect of Virtual Reality systems. While 360 video requires a lot of bandwidth, users only see visible tiles, therefore a large ... -
An effective foveated 360° image assessment based on graph convolution network
(2022-09-06)Virtual reality (VR) has been adopted in various fields such as entertainment, education, healthcare, and the military, due to its ability to provide an immersive experience to users. However, 360° images, one of the main ... -
Flexible HTTP-based Video Adaptive Streaming for good QoE during sudden bandwidth drops
(2023)We have observed a boom in video streaming over the Internet, especially during the Covid-19 pandemic, that could exceed the network resource availability. In addition to upgrading the network infrastructure, finding a way ... -
An Evaluation of the Impact of Distance on Perceptual Quality of Textured 3D Meshes
(2024-01)Distance-aware quality adaptation is a potential approach to reduce the resource requirement for the transmission and rendering of textured 3D meshes. In this paper, we carry out a subjective experiment to investigate the ... -
