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...
Qualitative online billing system performance is essential for cost-effective service providers. This paper presents the method of technical resources' distribution of the billing server based on the resource requirements of different types of service that takes into account the daily load statistics of different types of services and increases the revenue by providing an individual approach to services...
In this paper, we propose an effective design and implementation of a versatile embedded multimedia live streaming decoder system based on TI's DM814x processor, which can not only decode video live streams of various video codecs(H.264, MPEG-4, etc.), audio live streams of various audio codecs(AAC, MP3, G.711, etc.), but also demultiplex (demux) MPEG-2 TS, decode video stream and audio streams inside,...
Nowadays we are witnessing the development of digital broadcast television. One famous standard of digital broadcast is a Digital Video Broadcast (DVB). DVB is a family of standardize technologies designed to transmit video, audio, and multimedia services. In this work we develop small scale DVB system using computer equipped with DVB modulator to broadcast information or entertainment for students...
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...
Building a cloud-based e-learning platform using the approach of the research field of learning analytics is the overall goal of this research study. With the strengths of a cloud service it is possible to add value to the learning process for all stakeholders. With such a solution, the process of collecting, analyzing and interpreting data becomes rather easily. This research study aims to introduce...
In this paper, we optimize resource allocation for multimedia cloud based on queuing model. Specifically, we optimize the resource allocation in both single multimedia service provider (MSP) scenario and multiple MSPs scenario. In each scenario, we formulate and solve the MSPs' revenue maximization problem under eviction probability constraint of users. Numerical results demonstrate that the proposed...
Quality of Experience (QoE) is defined as the overall acceptability of an application or service, as perceived subjectively by the end user including the complete end-to-end system effects. That means QoE may be influenced by the user expectations and context, adding a subjective component to measurements. Nevertheless, it has been studied that some metrics of Quality of Service (QoS), more related...
With the rapid development of network technology, human beings gradually stepped into a new era. College teaching way has not make full use of network resources, especially sports teaching, the traditional teaching method still occupies the dominant position. In recent years, as a result of college expansion, caused part of the site and the shortage of teachers College. The emergence of network teaching,...
The adoption of the Internet of Things (IoT) paradigm constitutes the basic building block to progress towards unified ICT platforms for a variety of applications within the large framework of the smart cities. Unfortunately, designing a general architecture for IoT is still a very complex challenge, since in such system may be involved several devices, link layer technologies and services. Cultural...
Mobile ad-hoc network (MANET) can be defined as a network that is dynamically formed from randomly located mobile devices. SIP protocol allows two remote parties to initiate a call using centralized entities such as a proxy and location registrar. In order to enable the usage of an inherently centralized protocol such as SIP over a distributed environment such as MANET a lot of adaptation should be...
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...
Improvement and development of handheld devices such as tablets or smartphones opens new possibilities for them to be used in DTV environment. Handheld devices' proliferation has modified the way users watch and perceive TV. Giving users more control over their TV and easier access to additional information from their handheld devices is the focus of this paper. In this paper remote DTV content presentation...
The Internet of Things (IoT) is posing new challenges and opportunities for data management and analysis techniques. One of the major problems is how to handle an increasing amount of data, with a variety of data types and data sources, in order to meet application-specific performance requirements. In this article, we address the suitability of different types of databases for storing and accessing...
The recent development of hybrid broadcasting environments has meant that video delivery has attracted great attention. In hybrid broadcasting environments, clients can receive data both from a broadcasting system and a communication system. Some interruption time reduction methods have been proposed for video delivery in these environments. However, in these methods, the server does not change the...
The traditional personal computers have many security problems and are difficult to manage, thus desktop virtualization has been widely used due to its centralized management characteristic in solving the above issues [1]. In this paper we propose and discuss using Virtual SAN to enhance the performance of virtual desktop infrastructure. Using Virtual SAN can not only meet the requirement of virtual...
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...
This paper describes integration of RVU remote user interface and DLNA media player plug-ins in Qt framework. Usage of RVU concept introduces possibility to achieve same user experience across various platforms such as Android, iOS, Linux, etc. Integration of RVU concept into Qt framework enables execution of Qt applications in home network environment. Qt application is stored and executed on the...
An Internet-based security monitoring platform including a server and some clients is described in this paper for multimedia content authentication. Contents existed in the database of the server, can be discovered by the video hash copy detection technology and will be prevented from uploading. Watermark can be embedded into the videos when they are uploaded to the server in order to protect the...
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...
