Client intelligence for adaptive streaming solutions

TLDR
This paper proposes a method to compute a set of optimal client strategies for continuous video playback by optimizing the overall video quality by proper selection of the next chunk from the encoded versions.
Abstract
In state-of-the-art adaptive streaming solutions, to cope with varying network conditions, the client side can switch between several video copies encoded at different bit-rates during streaming. Each video copy is divided into chunks of equal duration. To achieve continuous video playback, each chunk needs to arrive at the client before its playback deadline. The perceptual quality of a chunk increases with the chunk size in bits, whereas bigger chunks require more transmission time and, as a result, have a higher risk of missing transmission deadline. Therefore, there is a trade-off between the overall video quality and continuous playback, which can be optimized by proper selection of the next chunk from the encoded versions. This paper proposes a method to compute a set of optimal client strategies for this purpose.

Probe and Adapt: Rate Adaptation for HTTP Video Streaming At Scale

TL;DR: It is argued that it is necessary to design at the application layer using a "probe and adapt" principle for video bitrate adaptation, which is akin, but also orthogonal to the transport-layer TCP congestion control, and PANDA - a client-side rate adaptation algorithm for HAS is presented.

Adaptation algorithm for adaptive streaming over HTTP

TL;DR: This work designed and implemented a receiver-driven adaptation algorithm for adaptive streaming that does not rely on cross-layer information or server assistance and integrated the algorithm with a prototype implementation of a streaming client based on the MPEG DASH (Dynamic Adaptive Streaming over HTTP) standard.

QoE-Driven Rate Adaptation Heuristic for Fair Adaptive Video Streaming

TL;DR: A novel rate adaptation algorithm, capable of increasing clients’ Quality of Experience (QoE) and achieving fairness in a multiclient setting, is proposed, which can improve fairness up to 80% compared to state-of-the-art HAS heuristics in a scenario with three networks.

Image quality assessment: from error visibility to structural similarity

TL;DR: In this article, a structural similarity index is proposed for image quality assessment based on the degradation of structural information, which can be applied to both subjective ratings and objective methods on a database of images compressed with JPEG and JPEG2000.

Subjective impression of variations in layer encoded videos

TL;DR: To a large degree existing (unproven) assumptions about quality degradation caused by variations in layer encoded videos are validated, however there were also some interesting, at first sight counterintuitive findings from the experiment.
