360-Degree Video Quality Evaluation
2018 Picture Coding Symposium (PCS), 2018360-degree video is emerging as a new way of offering immersive visual experience. The quality evaluation of 360- degree video is more difficult compared to the quality evaluation of conventional video. However, to ensure successful development of 360-degree video coding technologies, it is essential to precisely measure both objective and subjective ...

Optimizing HAS for 360-Degree Videos [PDF]
NOMS 2020 - 2020 IEEE/IFIP Network Operations and Management Symposium, 2020 In recent years, an increasing number of Internet-based applications have been released that use virtual reality for education, training, gaming, and various forms of entertainment. When transmitting an omnidirectional 360° video over the Inter-net, it consumes considerably more data compared to traditional video streaming. To overcome the high network

Currently there exists no agreed-upon user experience guidelines regarding subtitling (closed captions) in immersive 360-degree video experiences. It is not clear how subtitles might be acceptably displayed within this context, namely to support the balance between comprehension, freedom to look around the scene, and immersion.

Characterization of 360-degree Videos
Proceedings of the Workshop on Virtual Reality and Augmented Reality Network, 2017Online streaming of Virtual Reality and 360° videos is rapidly growing, as more and more major content providers and news outlets adopt the format to enrich the user experience. We characterize 360° videos by examining several thousand YouTube videos across more than a dozen categories.

Popularity-Aware 360-Degree Video Streaming
IEEE INFOCOM 2021 - IEEE Conference on Computer Communications, 2021Tile-based streaming techniques have been widely used to save bandwidth in 360° video streaming. However, it is a challenge to determine the right tile size which directly affects the bandwidth usage. To address this problem, we propose to encode the video by considering the viewing popularity, where the popularly viewed areas are encoded as macrotiles

Viewport Margins for 360-Degree Immersive Video
2020 IEEE 22nd International Workshop on Multimedia Signal Processing (MMSP), 2020Immersive 360-degree video delivery is more and more widespread. New use cases are constantly emerging and make it a promising video technology for Extended Reality applications. Viewport Dependent Delivery (VDD) is an established technique used for saving network bit rate when transmitting omnidirectional video. One of the hardest challenges in VDD of

Viewport-adaptive 360-degree video coding
Multimedia Tools and Applications, 2020360-degree videos contain an omnidirectional view with ultra-high resolution, which will lead to the bandwidth-hungry issue in virtual reality (VR) applications. However, only a part of a 360-degree video is displayed on the head-mounted displays (HMDs).
