This paper presents experimental measurements of RealMedia audio/video streaming applications on an IEEE 802.11b wireless LAN. Empirical traffic measurements collected using a wireless network analyzer are used to characterize RealMedia streaming workloads, and to assess their impacts on wireless network performance. In addition, we study the relationship between the wireless channel error rate...

The continuous processing of streaming data has become an important aspect in many applications. Over the last years a variety of different streaming platforms has been developed and a number of open source frameworks is available for the implementation of streaming applications. In this report, we will survey the landscape of existing streaming platforms. Starting with an overview of the evolv...

This paper describes a channel-adaptive packet scheduler for improved error control performance in a peer-cooperative distributed media streaming system. The proposed packet-scheduling algorithm was designed for the case in which streaming server peers rely on an errorrecovery strategy using retransmission and application-layer automatic repeat request rather than error protection using forward...

Cytoplasmic streaming is crucial for cell homeostasis and expansion but the precise driving forces are largely unknown. In plants, partial loss of cytoplasmic streaming due to chemical and genetic ablation of myosins supports the existence of yet-unknown motors for organelle movement. Here we tested a role of the endoplasmic reticulum (ER) as propelling force for cytoplasmic streaming during ce...

In this paper, an end-to-end Quality of Service (QoS) framework for streaming services in 3G mobile networks is considered. A solution based on a Public Land Mobile Network (PLMN) hosted multimedia streaming service is studied to avoid accessing through an external IP packet data network (IP-PDN) to streaming services. Under this scenario, the interaction between UMTS and IETF’s protocols and m...

Ultrahigh definition video streaming has been explored in recent years. Most recently the possibility of 4kUHD video streaming over wireless 802.11n was presented, using preencoded video. Live encoding for streaming using x264 has proven to be very slow. The use of parallel encoding has been explored to speed up the process using CUDA. However there hasnot been a parallel implementation for vid...

A streaming media system is a soft real-time system according to streaming media service features. Some soft real-time tasks and best-effort tasks will be starved when using traditional RM algorithm to schedule streaming media services. Aiming at this problem, an improved RM algorithm with elastic priority is proposed in this paper. The algorithm can prevent periodic streaming media tasks from ...

In adaptive HTTP streaming model, the HTTP server stores multiple representations of media content, encoded at different rates. It is the function of a streaming client to select and retrieve segments of appropriate representations to enable continuous media playback under varying network conditions. In this paper we describe design of a control mechanism enabling such a selection and retrieval...

We present the design and prototype of GnuStream, a peerto-peer (P2P) and receiver-driven media streaming system. GnuStream is built on top of Gnutella, and it integrates dynamic peer location and streaming capacity aggregation. Each GnuStream streaming session is controlled by the receiver peer and involves a dynamic set of peer senders instead of one fixed sender. The receiver aggregates stre...

Compared with the traditional video streaming media system based on C/S mode, the video streaming media system based on P2P can efficiently solved the problems like single point of failure, high construction cost. Therefore, this study implemented a video streaming media system to provide the video streaming media service of high quality and large capacity. A mobile P2P video streaming media sy...
