Head-motion-aware viewport margins for improving user experience in immersive video
(ACM, 2022-01-10)
Viewport-dependent delivery (VDD) is a technique to save network resources during the transmission of immersive videos. However, it results in a non-zero motion-to-high-quality delay (MTHQD), which is the delta time from ...
Adaptive streaming of content-aware-encoded videos in dash.js
(IEEE, 2022-05)
In Hypertext Transfer Protocol (HTTP) adaptive streaming, the client makes rate adaptation decisions based on the measured network bandwidth and buffer fullness. This simplifies the adaptation logic; however, it often ...
Take the red pill for H3 and see how deep the rabbit hole goes
(ACM, 2022-03-17)
With the introduction of HTTP/3 (H3) and QUIC at its core, there is an expectation of significant improvements in Web-based secure object delivery. As HTTP is a central protocol to the current adaptive streaming methods ...
The benefits of server hinting when DASHing or HLSing
(ACM, 2022-03-17)
Streaming clients almost always compete for the available bandwidth and server capacity. Not every client's playback buffer conditions will be the same, though, nor should be the priority with which the server processes ...
Benchmarking the second edition of the omnidirectional media format standard
(IEEE, 2022)
Omnidirectional MediA Format (OMAF) is the first worldwide virtual reality (VR) standard to store and distribute immersive media, completed in 2019. Later, in 2021, the second edition of this standard (OMAF v2) was published. ...
Automated adaptive playback for encoder-adjudicated live sports
(IEEE, 2022)
In low-latency live streaming, it is not easy to simultaneously avoid stalls and maintain low latency. The trade-off needs to be decided in real time. One of the best tools for controlling the buffer level (hence, the ...
Rate-adaptive streaming of 360-degree videos with head-motion-aware viewport margins
(IEEE, 2022)
Efficient use of available bandwidth is vital when streaming 360-degree videos as users rarely have enough bandwidth for a pleasant experience. A promising solution is the combination of viewport-dependent streaming using ...
Catching the moment with LoL + in twitch-like low-latency live streaming platforms
(IEEE, 2022)
Our earlier Low-on-Latency (dubbed as LoL) solution offered an accurate bandwidth prediction and rate adaptation algorithm tailored for live streaming applications that targeted an end-to-end latency of up to two seconds. ...
Marrying WebRTC and DASH for Interactive Streaming
(ACM, 2022-03-17)
WebRTC is a set of W3C and IETF standards that allows the delivery of real-time content to users, with an end-to-end latency of under half a second. Support for WebRTC is built into all modern browsers across desktop and ...
