Improving server and client-side algorithms for adaptive streaming of non-immersive and immersive media
(The ACM Digital Library,, 2021)
HTTP adaptive streaming is a technique widely used in the internet today to stream live and on-demand content. Server and client-side algorithms play an important role in achieving a better user experience in terms of ...
Common media client data (CMCD): Initial findings
(Association for Computing Machinery, Inc, 2021-07-16)
In September 2020, the Consumer Technology Association (CTA) published the CTA-5004: Common Media Client Data (CMCD) specification. Using this specification, a media client can convey certain information to the content ...
Content-aware playback speed control for low-latency live streaming of sports
(The ACM Digital Library, 2021)
There are two main factors that determine the viewer experience during the live streaming of sports content: latency and stalls. Latency should be low and stalls should not occur. Yet, these two factors work against each ...
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 ...
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. ...
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. ...
Bandwidth prediction in low-latency media transport
(ACM, 2023-06-16)
Designing a robust bandwidth prediction algorithm for low-latency media transport that can quickly adapt to varying network conditions is challenging. In this paper, we present the working principles of a hybrid bandwidth ...
