Segment duration for rate adaptation of adaptive HTTP streaming

2011 IEEE International Conference on Multimedia and Expo, 2011
Recently, 3GPP packet-switched streaming (PSS) specified adaptive HTTP streaming (AHS). The client requests series of media segments and adapt the bitrates of segment to varying network resources. The current state-of-the-art rate adaptation of AHS estimates the end-to-end network capacity using the previous segment reception such as segment fetching ...

Adaptive Streaming of Stereographic Video

2009
We present a tool for online compression and streaming of stereoscopic video and images and a consideration on adaptation of the video stream to network conditions. The software allows to use different encoding schemes for video compression and streams the stereo frames using UDP protocol.

Adaptive Video Streaming

Signal and Image Processing, 2011
In this paper we present an approach for designing an adaptive video compression system that allows regions of interest to be identified and the picture size and quality configured to optimize performance for a system computation and communication capabilities.

QoE-optimal rate adaptation for HTTP adaptive streaming

2016 IEEE/CIC International Conference on Communications in China (ICCC), 2016
HTTP Adaptive Streaming(HAS) has become widely deployed in multimedia services for its ability for providing the best Quality of Experience(QoE) for viewers with limited resource, especially in fluctuating wireless networkings. With its client-driven rate adaptation mechanism, HAS is able to adapt to fluctuating network condition and various terminals ...

Request adaptation for adaptive streaming over HTTP/2

2016 IEEE International Conference on Consumer Electronics (ICCE), 2016
In this paper, we propose a client-based adaptation method for Adaptive Streaming over HTTP/2 leveraging the server push feature. A cost function that takes into account both the number of pushed segments and the playout buffer level is defined. Experiment results show that the proposed method can improve the tradeoff between the number of requests and

Stream switching with in-stream transmission rate probing for adaptive mobile multimedia streaming

2010 IEEE International Conference on Image Processing, 2010
In this paper a new stream switching algorithm for mobile multimedia streaming is proposed. Special emphasis is given to the up-switching decision. In order to avoid false up-switches of the media content rate and consequential toggling behavior of the media quality, transmission rate probing within a multimedia stream is combined with bit-stuffing ...

Adaptive pre-recorded multimedia streaming

Global Telecommunications Conference, 2002. GLOBECOM '02. IEEE, 2004
Lately, multimedia-related Internet applications have become very popular, and make up an increasing percentage of network traffic. This paper presents a quality-of-transmission-orientated adaptive mechanism for streaming of pre-recorded multimedia content.

CoS enforcement for HTTP adaptive streaming

2012 IEEE Globecom Workshops, 2012
As the HTTP-based segmented video delivery paradigm continues to grow in popularity, the ability to enforce differentiated classes of service (CoS) across large numbers of clients becomes increasingly important. Differentiated services are an important monetization technique for content service providers.

Adaptive video streaming over HTTP

Proceedings of the 2014 ACM Southeast Regional Conference, 2014
A new video streaming scheme is proposed and its prototype is implemented in this paper. The scheme is designed for providing an enhanced QoS for a client using a mobile device. With the scheme, the client considers various important network factors to decide its bit rate. It then sends feedback whenever its current bit rate must be changed. Based upon

Quality Adaptation with Temporal Scalability for Adaptive Video Streaming

2008
In video streaming applications over the Internet, TCP- friendly rate control schemes are useful for improving network stability and inter-protocol fairness. However it does not always guarantee a smooth quality for video streaming. To simultaneously satisfy both the network and application requirements, video streaming applications should be quality ...
