Rate adaptation for adaptive HTTP streaming
Proceedings of the second annual ACM conference on Multimedia systems, 2011Recently, HTTP has been widely used for the delivery of real-time multimedia content over the Internet, such as in video streaming applications. To combat the varying network resources of the Internet, rate adaptation is used to adapt the transmission rate to the varying network capacity. A key research problem of rate adaptation is to identify network

Toward HTTP adaptive streaming
Proceedings of the 11th ACM Multimedia Systems Conference, 2020With increasing popularity of smart devices and better bandwidth allocations for end users, online video streaming demand is rising. As an Over-the-Top (OTT) service provider, we implemented HTTP Adaptive Streaming (HAS) technology to address this concerns by considering limitations of legacy streaming protocols.

Adaptive, unsupervised stream mining
The VLDB Journal, 2004Sensor devices and embedded processors are becoming widespread, especially in measurement/monitoring applications. Their limited resources (CPU, memory and/or communication bandwidth, and power) pose some interesting challenges. We need concise, expressive models to represent the important features of the data and that lend themselves to efficient ...

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.

Combining Stream Switching with Fine-Grained Intra-Stream Adaptation for Adaptive Video Streaming
2005 IEEE 7th Workshop on Multimedia Signal Processing, 2005Video streaming systems in best effort networks have to somehow cope with dynamically changing bandwidth. Various scalable video codecs allow intra-stream adaptation by use of temporal, spatial, or quality (SNR) scalability; optimizations for finer grained scalability are available as layered coding and FGS techniques.

Widespread adoption of broadband Internet and the introduction of multimedia-capable mobile devices enable the proliferation of many streaming video services. However, best-effort networks are not natively designed to such a purpose. They do not provide any guarantees for delivering the content on time or offer constant service quality.

Adaptive Multi-Path Video Streaming
Eighth IEEE International Symposium on Multimedia (ISM'06), 2006Multiple description codes are designed for multiple path video streaming with channel diversities. In this paper, we investigate the performance of multi-path video streaming using a multiple description coding (MDC) technique. An efficient MDC technique based on spatial domain processing is applied.

Proceedings of the 12th ACM International Conference on Computing Frontiers, 2015
In November 2014, MPEG released a new standard, named Green Metadata, that enables energy-efficient media consumption on consumer devices [4]. This standard specifies metadata for reduction of power consumption during encoding, decoding and display. It specifies in particular some metadata for energy-efficient media selection using DASH standard [3 ...

Watermarking for Adaptive Streaming Protocols
2011Online multimedia distribution is often done by means of adaptive streaming protocols. To protect this content, its owners apply a unique watermark to each copy. However, sending a unique copy to each client incurs a prohibitive cost, especially in terms of bandwidth and server load, and embedding a watermark on a client device not only compromises the
