Video streaming and computer games are among the most popular and highest bandwidth consuming media in the Internet. Video contents consume around 70% of the total bandwidth usage in the Internet today. Advancements in media generation tools, high processing power, and high speed connectivity have enabled generation of live, interactive, multi-view media generation. Cognitive assisted and online multi-player...
The broadcasting industry has recently begun to adopt statistical multiplexing based network platform in their workflow to support professional live audio/video (AV) transmission instead of the Time Division Multiplexing (TDM) based system. These audio-over-packet switched systems require a carefully designed and managed network to ensure key quality measures of the real-time (RT) media, such as low...
In emergency scenarios, e.g., natural disasters, the infrastructure of telecommunication system is partially or even completely disrupted. While the bandwidth and energy resources of system are limited, the maltimedia communication demand of myriad usen may reach the peak of data traffic. This in tum makes the system more challenging to serve the users high quality of maltimedia streaming with con...
Video-on-demand (VOD) system allows users to access media any time without the need to leave their home. Hard disk drive (HDD) has become popular for VOD storage to store and deal with a large amount of data. In practical cases, disk storage throughput is limited by a slow HDD and disk operating degrades drastically when the server needs to serve many simultaneous video streams. On the other hand,...
Today, when the content provider transmits a video, he usually uses forward error correcting to protect the packets which caused a lot of redundancy. If we know parts of the media stream are more important than others, we can uses bandwidth more efficiently. In this paper, we analyze the structure of the video stream, the frame types and the dependence among frames and propose an optimized scheme...
In this paper we implement a recurrent high order neural network based controller (built into a Client-Server architecture), in order to provide QoS control. The scheme is based on a recently proposed QoS control algorithm with proven stability and robustness properties. Mild assumptions have been used to construct a user satisfaction function that depends on two media characteristics (i.e. color...
In Multimedia network applications, adaptive mobile streaming empowers cloud-based real time transcoding. The researchers in media cloud propose a well-organized technique to split the video content into different frames. The technique is to carry out disseminated encoding to resolve the multimedia data conversion problem. Also, it introduces an energetic outgoing and an extrapolative bandwidth for...
This paper proposes a novel network architecture for optimal and balanced provision of multimedia services, exploiting a resource prediction system. This architecture enables for the long-term prediction of multimedia services future demands, based on the history of previous network resources usage. The proposed research approach provides the opportunity for the optimal distribution of streaming data,...
The proliferation of the Internet technology has contributed to an increasing demand for streaming applications. The adaptation of multimedia streaming content according to context information is essential to supporting these applications. In this paper, we design a context-aware multimedia quality adaptation framework for smart streaming. The proposed framework seamlessly provides multimedia data...
Most studies on the perceptual quality evaluation of multi-media services are limited to short media samples or epi-sodes, although typical usage of services occurs in a more regular way over longer periods of exposure (weeks, months or years). So far, it is unclear how the experience of individ-ual episodic use is integrated to form an experience of one service as a whole, spanning over multiple...
Free viewpoint video (FVV) is a new approach of interactive streaming services, where users are able to freely change their viewpoint. The desired viewpoint is synthetized from two or more camera views that must be delivered to the users depending on their continuously changing perspective. Multicast delivery of camera streams is an appropriate solution, however due to network latency and frequent...
The Transmission of multimedia content typically has bandwidth, delay and loss issues. Video compression, layer, media distribution services, streams servers, synchronization technique and synchronization protocols for streaming are major areas of research. It require scheduling protocol to sequence the events. Various useful applications for streaming in internet world are available and their implementation...
Currently, computer technology has been widely used in the teaching of higher mathematics, which lead to a revolutionary change to the traditional teaching theory, method, means and structure and has played a positive to promote the effect of higher mathematics teaching. But, there are several imperfections are occurred in the practical process of computer aided teaching. Therefore, it is necessary...
With increasing interest in the concept of cloud multimedia and the popularization of hand-held devices, users gradually view videos in mobile network streaming mode rather than off-line mode. However, the delays and lags resulted from the instability of a mobile network will greatly degrade streaming quality for users. In cloud multimedia streaming services, when there are multiple optional streaming...
The increasing use of complex multimedia services requires advanced resource management mechanisms, in particular in wireless network environments. Since multimedia services may contain several media flows, the number and properties of which may vary during an ongoing session, and because user preferences regarding flow importance may also vary, we use “user” and “service” related knowledge at session...
This paper presents the usage of Content Centric Networking (CCN) for adaptive multimedia streaming in mobile environments, leveraging the recent ISO/IEC MPEG Dynamic Adaptive Streaming over HTTP (DASH) standard. The performance of DASH over CCN is evaluated using real-world mobile bandwidth traces and compared to previous evaluations of different DASH-based as well as proprietary systems. As there...
Content Delivery Cloud (CDC) extends Content Delivery Network (CDN) to provide elastic, scalable and low cost services to the customers. For multimedia streaming over CDC, caching the media content onto the edge server from storage cloud is commonly used to minimize the latency of content delivery. It is very important for CDN to balance between the resources being used (storage space, bandwidth,...
In this paper, we propose Scale Stream, a new algorithm to support scalable multimedia streaming in peer-to-peer networks, under strict resources constraints. With the growth of multimedia consumption over the Internet, achieving scalability in a resource-constrained environment is indeed becoming a critical requirement. Intuitively, our approach consists in dynamically replicating the multimedia...
HTTP Streaming plays an important role in today's multimedia distribution over internet. Besides the data rate of network, the quality of user experience of HTTP Streaming is also related to multimedia's distortion that server could limit under a certain bit-rate. Given a specific bandwidth, how to provide the HTTP Streaming client the multimedia content with the least distortion in HTTP Streaming...
For delivering multimedia services over (wireless) networks it is important that the mechanisms which negotiate and optimize content delivery under resource constraints take into account user perceived quality in order to improve user satisfaction. Within the scope of the IP Multimedia Subsystem (IMS) architecture a novel application server may be added which handles multi-user multi-flow Quality...
