Real-time interactive communications have become critical for business, e-commerce, e-government and education. Teleconferencing systems have been usually deployed using proprietary and expensive systems. Overlay networks are often used to support multi-point teleconferencing and provide services unavailable in the underlying physical networks. With the advent of WebRTC, real-time communication applications...
This paper proposes a method for fast channel switching using the MPEG Media Transport (MMT) standard. Based on the multimedia data formats specified in MMT, data units such as media processing units (MPU) and signaling messages will be sent according to the order derived from data unit format. During broadcast, the MPU size is designed with careful consideration of bandwidth utilization and synchronization...
In this work, we propose a fragmentation resilient IP identification based data embedding method. First, we analyze the IP identification generation in various operating systems to validate the feasibility of our proposal. Then, we put forward our proposal to embed data into IP identification field while considering data from the payload field. Results suggest that the proposed method resembles the...
This paper presents an architecture for monitoring the presentation of multimedia declarative applications, providing feedback about variables states, object properties, media presentation times, among others. Monitoring tools that follow the proposed architecture are able to detect if visual problems are being caused by programming errors or by player malfunctioning. The architecture presents a communication...
Real-time video dissemination over Vehicular Ad hoc Networks (VANETs) is fundamental for many services, e.g., emergency video delivery, road-side video surveillance, and advertisement broadcasting. These applications deal with several challenges due to strict video quality level requirements and highly dynamic topologies. To handle these challenges, geographic receiver-based beacon-less approaches...
This paper describes advanced networking technologies that support high quality video and image communications. We focus on maintaining Internet compatibility and extracting the merit of ATM technologies. A concept of Global Mega-media Network (GMN) is introduced as the future multimedia network. As part of work associated with GMN, an overview of AMInet project and some of the promising technologies...
Cloud computing has enabled a wide range of streaming multimedia applications and many HDMI based devices have emerged as a result. Chromecast is one of these devices that plugs into the HDMI port of a larger screen and turns it into a smart screen. With Chromecast, you can stream videos from the cloud onto a larger screen and control it from a mobile device such as a smart-phone, tablet or a laptop...
Voice over Internet Protocol (VoIP) is one of the most popular technologies nowadays that facilitate the user by providing different features as instant messages, phone calls, video calls, and voicemails. Basic VoIP protocols were designed to be efficient instead of secure. After numerous attacks on these protocols several solutions were proposed to prevent against these threats. In this paper, we...
Recent advances in embedded computer electronics and integration in multimedia standard specifications are enabling cost-effective terminals for video communication and conferencing with potential capabilities in video surveillance application, both on wireless and wired links. Following a tutorial approach, the paper describes the practical implementation of a multimedia system and terminals implemented...
In recent years, the number of appliances connected to the Interned has steadily increased thanks to the wide popularity of WÌFÌ/3G enabled mobile devices. This has led to an increase of multimedia resource consumption, causing traffic overload problems for classic resource providers. Different solutions have been studied to shift this traffic overhead from the server(s) towards the client(s) through...
Now days, big data (e.g. multimedia content, document, data in social network, etc) is growing fast and requiring more big storage area which is capable to process all that data efficiently in short time as well as having efficient delivery system to deliver that data to diversity of devices when they access the internet anytime from anywhere.
Multimedia applications have become the prime source of Internet traffic in recent years due to high bandwidth offered by almost all access mechanisms. This highlights the need of intense research efforts to improve the already demanding user perception levels for high-performance video delivery networks. Quality of Experience (QoE) based metrics are often used to quantify user satisfaction levels...
Modern learning system offered in a recent era of technology is the one that employ computer and network technology, Video-on-Demand (VoD). The implementation on VoD on learning system presents an opportunity to access the multimedia content any time without concern about place and time. One thing that should be put on apprehension is the bandwidth consume by the architectures. On this paper, we study...
The process of network convergence and the increased availability of high speed networks has opened a number of possibilities in the field of multimedia content distribution. Above all, the popularity of mobile platforms and the accompanying user mobility requires the distribution platforms to be able to respond to changing network conditions and to maintain a satisfactory quality of service regardless...
The Emergence of WEB 2.0 and social media technologies facilitates many social computing applications such as THREADLESS, WIKIPEDIA, GOOGLE and much more as a gateway of mediums in which vast amount of data is shared and discussed globally. These new internet technology platforms multiple broadways in which problems are shared and discussed, thus leveraging patron's globally to contribute collective...
As a technical method over VANETs, video delivery has the potential power to enhance the application experience associated with traffic safety, management and infotainment. The experience of user is seriously affected by the quality of the video display. Therefore, Quality of Experience (QoE) enhancement for video delivery in VANETs is an important issue. However, the high mobility and dynamic nature...
Emergency warning applications in a vehicular ad hoc network (VANET) requires successful dissemination of warning notification within a geographical area spanning multiple hops. Multimedia transmission provides an accurate overview of the emergency event in the form of an image, an audio or a video. However, the reliable transmission of emergency multimedia messages using multi-hop broadcast techniques...
As the demand of the rapid development of information in modern society, based on the development in computer technology, multimedia technology and network technology, reform of education system in our country enters a new step. The modern teaching method reform has become an important part of education reform. More and more workers take the computer network teaching system as one of the important...
Cooperative multiple-input-single-output (CMISO) introduces cooperative nodes (Coops) to reduce the energy consumption of the cluster head (CH) in cluster-based M2M capillary networks. Although CMISO reduces energy consumption of CH, it introduces additional energy overhead to Coops, which contributes to a reduction of network lifetime. In this paper, we propose a joint CH and Coops selection (JCCS)...
This paper describes an implementation of RVU client on Android based devices. RVU represents a protocol based on client-server architecture and uses UPnP and DLNA to establish communication and share content. The key benefit of RVU is the user interface (RUI) implementation, an approach that enables content service providers to deliver consistent user interface to all RVU client devices in a “Connected...
