There is a wide-ranging use of Peer-to-Peer (P2P) computing and applications in majority of the key areas of Engineering and Technology. Devoid of any centralized server, they can share their content since peers are linked with each other. This is the reason why P2P computing gives enhanced communication among peers. It is essential for the video server to maintain the data content link in cache memory...
Well-known media applications of Chromecast such as YouTube, Viki usually use a time slider on the second screen for video navigation. However, the time slider does not offer easy way to access particular contents. Here we propose an aligned thumbnails-based video browsing system with Chromecast using content-based video browsing approach by automatically detecting scenes. It uses hierarchical sliding...
We propose a synchronized playback method for the real-time synchronization of the playback position of streaming media to multiple clients from a streaming server. The playback-related information that is used in this synchronized playback method comprises the current time and the playback position, and the server transmits the playback position and the current time to the client. The client can...
Dynamic Adaptive Streaming over HTTP (DASH) is a new and promising streaming protocol, based on the Media Presentation Description (MPD) specification. With the increasing demand for Internet video streaming, methods for profiting from video services are gaining increased interest. In this paper, we propose a novel algorithm for server side video ad insertion over the DASH standard. The proposed method...
The media multitasking is general user behavior nowadays as the second screen devices, such as tablet PCs, are widely spread. The content providers and advertisement industry figure out this phenomenon as an opportunity and attempt to develop various types of second screen services. However, the conventional second screen services are confined in the broadcasting and over-the-top application. Therefore,...
We propose in this paper a platform enabling advanced real-time communication (RTC) services in a very unified manner. Audio/video RTC is converged with other (not necessarily real-time) information and in-/output from users to create a new, richer communication experiences. More concrete, the proposed platform is capable of tailoring audio/video communication streams to converge their real-time payload...
Segment transmission scheduling is essential in peer to peer video streaming. Transmission of the video segments faces some difficulties. Long playback buffering delay and high chunk miss ratio are the major ones of these difficulties. This paper introduces a proposed framework to overcome these difficulties. Moreover, it improves the overall performance of the streaming system. The framework is described...
Media streaming services are responsible for the significant increase of Internet traffic. This fact generates the need for better computing resources management in order to maintain such services always available. Cloud computing offers an elastic infrastructure that provides computing resources on demand in order to maintain such services always available. Moreover, emerging network architectures,...
The paper present a framework for video playing and video storage based on Hadoop. Our framework consist of 3 layers. CDN for receiving clinets' requests; CCN for connecting clients and sending data; Hadoop cluster for data storage. This kind of structure helps to provide high availablility services, which could support high concurrent access and play smooth streaming media in mobile terminals.
Virtualization and cloud client-computing can support high-quality media services such as IPTV and smart TV in a multi-device service environment. Because the device can be a thin-client, we can provide services and devices economically. We describe streaming-based cloud client-computing media service system, interface architecture and application performance. Our system provides high-definition media...
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...
The paper discuses the potential of the WebRTC in a multi-user video conference. All the signaling for multi-user video conferences is sustained by the XMPP server. Currently this technology is being deployed on Google Chrome, Opera and Firefox web-browsers. Without a standardized solution, service providers can implement various types of architectures. In this paper we propose a multi-video web conference...
In this paper, we present the performance of DVFS governors for DASH based mobile video streaming. Selection of DVFS governors affects the performance and energy consumption of a mobile phone but decision of determining video streaming quality in DASH client.
To effectively utilize storage space of edge streaming media servers, cache policies are being studied. Unlike traditional work that focused on hit ratio and overall system bandwidth cost, this paper recognize different significance of users and propose the concept of caching utility as a new metric to evaluate caching strategies. A user based caching algorithm, USCS, involving differentiated service...
As mobile traffic grows, the mobile operators need to handle video delivery in the mobile network to reduce their network cost and to enhance Quality of Experience. In order to address network operators needs, first, we listed up the mechanism for mobile contents delivery optimization solutions. Second, we identified the common two key features, which are caching and media adaptation. Finally, we...
This paper presents a proposition for design and realization of a multi-format streaming server framework. Building blocks required to implement this framework are identified, and their implementation described using existing technologies and protocols. Presented framework addresses the problems surrounding the distribution of Digital Television (DTV), as well as local media content, to a wide array...
This paper designs an integrated multimedia system which is able to perform intelligent controls on media devices and services in a home-based context-aware environment. In this design, this proposed system functions both of intelligent media content distribution and multimedia convergence mechanisms. Not only local media fils but enormous Internet media streams can be advertised and distributed across...
High quality online video streaming, both live and on-demand, has become an essential part of consumers' every-day lives. The popularity of video streaming has placed a heavy burden on the network infrastructure that now has to transfer an enormous amount of data very quickly to the end-user. To further exacerbate the situation, the Video-on-Demand (VoD) distribution paradigm uses a unicast independent...
Today a variety of media streaming formats exist, which increases complexity, when distributing media to as many devices as possible. In this paper we present new standards that aim at unifying media delivery over the Internet, driving DRM-interoperability and enabling better Web applications.
Currently commercial live video streaming systems are based either on a typical client-server or on a peer-to-peer architecture. The former outperforms in terms of stability and quality of service, provided that the system is not stretched beyond its limits, while the latter is scalable and has a much lower cost of operation with regards to the required bandwidth resources. In this paper, we propose...
