A number of recent technological trends have made data intensive applications such as continuous media (audio and video) servers a reality. These servers are expected to play an important role in applications such as video-on-demand, digital library, news-on-demand, distance learning, etc. Continuous media applications are data intensive and might require storage subsystems that consist of hundreds of (multi-zone) disk drives. With the current technological trends, a homogeneous disk subsystem might evolve to consist of a heterogeneous collection of disk drives. Given such a storage subsystem, the system must continue to support a hiccup-free display of audio and video clips. This study describes extensions of four continuous display techniques for multi-zone disk drives to a heterogeneous platform. These techniques include IBM's Logical Track [21], HP's Track Pairing [4], and USC's FIXB [9] and deadline driven techniques [10]. We quantify the performance tradeoff associated with these techniques using analytical models and simulation studies. The obtained results demonstrate tradeoffs between the cost per simultaneous stream supported by a technique, the wasted disk space, and the incurred startup latency.

including the Berkeley MPEG player [6], TclProp, a data Conducting research on continuous media applications is hard, in part because it is necessary to have a complete multimedia system running to be able to evaluate changes to any component such as synchronization, network protocols, or encoding. The Berkeley Continuous Media Toolkit provides customizable support for an entire multimedia pipeline. This demonstration will illustrate several applications and research projects build using CMT while showing how CMT is used to build applications and experiment with innovative multimedia systems research.

In this paper, admission control issue is considered in the MAC level access protocol design for supporting the continuous media applications on HFC network. We treat service admission requests and interactive requests the different priority level requests. And the number of contention minislots of upstream channel for these two priority levels are not fixed. The headend checks the system resources and dynamically allocate the contention minislots for the service admission requests. For example, if there are not enough system resource to admit a new service request, the contention minislots for the service admission requests will be decreased and more contention minislots will be allocated to the interactive requests. A set of simulation scenarios is presented to show that the proposed scheme is suitable for continuous media applications.

With the popularization of network technology and the wide application of multimedia technology, the topic of interaction has become increasingly heated, and interactive media has become the focus of discussion. The continuous emergence of online games, online meetings, cloud classrooms and smart phones reflects the improvement of media interactivity. With lifelong learning, personalized learning, collaborative learning and other learning concepts deeply rooted in the hearts of the people, modern interactive media in education has also been applied. Researchers summarize the impact of the development of information technology on the evolution of modern interactive media; summarize the current situation of the application of modern interactive media education through interviews, questionnaires and other methods; analyze the problems existing in the application, promotion and application of modern interactive media, and put forward countermeasures to optimize the application of modern interactive media.

Javanese language is one of the lessons that students consider the most boring, especially for students at the level of Madrasah Ibtidaiyah or Elementary Schools. The teaching method of the teacher still uses conventional methods, namely the teacher explains with lectures and students listen to textbooks. The media used are limited to textbooks and white boards. Given the importance of these subjects, a new alternative is needed to support learning media for optimal learning. Although the learning media used currently exist, they are not optimal. So that development needs to be done in order to create more effective learning media. The methodology used is structured analysis and development, starting from analyzing the running system to the proposed system using UML. The final result achieved from this writing is the formation of a system procedure using UML. In addition, an android-based interactive learning media application design using APP Inventor was also produced. The formation of this interactive learning media application design is expected to optimize learning Javanese language subjects about word processing for Madrasah Ibtidaiyah students to support student learning at home and in the classroom.

Continuous media applications have an implied temporal dimension, i.e. they are presented at a particular rate for a particular length of time and if the required rate of presentation is not met the integrity of these media is destroyed. We present a set of language constructs suitable for the definition of the required QoS and the real-time dimension of the media that participate in a multimedia application. We propose a new modeling scheme where we can represent every different presentation by a periodic task and then we describe a method that provides low-level support to these language constructs. The emphasis of the proposed strategy is on deterministic guarantees and can be considered as a next step for the design and the implementation of predictable continuous media applications over a network.

Low-latency, interactive media applications (e.g., video conferencing) present a unique set of challenges for congestion control. Unlike TCP, the transport mechanism for interactive media needs to adapt fast to abrupt changes in available bandwidth, accommodate sluggish responses and output rate fluctuations of a live video encoder, and avoid high queuing delay over the network. An ideal scheme should also make effective use of all types of congestion signals from the network, including packet losses, queuing delay, and explicit congestion notification (ECN) markings. This paper presents a unified approach for congestion control of interactive video: network-assisted dynamic adaptation (NADA). In NADA, the sender regulates its sending rate based on a composite congestion signal calculated and reported by the receiver, which combines both implicit (e.g., loss and delay) and explicit (e.g., ECN marking) congestion indications from the network. Via a consistent set of sender adaptation rules, the scheme can reap the full benefits of proactive, explicit congestion notifications supported by advanced queue management schemes. It remains equally responsive in the absence of such notifications. Extensive simulation studies show that NADA interact well with a wide variety of queue management schemes: conventional drop-tail, random early detection (RED), recently proposed CoDel (controlled delay) and PIE (Proportional Integral controller Enhanced), as well as a token-bucket-based random marking scheme based on Pre-Congestion Notification (PCN). Furthermore, NADA reacts fast to changes over the network, allows for weighted bandwidth sharing among multiple competing video streams, and sustains a substantial share of bottleneck bandwidth when coexisting with TCP.

The paper proposes a dynamic QOS control scheme using a processor reservation system. In our scheme, a system allocates processor capacity for each application, then the application increases or decreases the current resource usage by using a feedback mechanism. This scheme allows the application to reserve resources optimistically. This means that a system can allocate all processor resources to respective applications every time. Our approach makes it easy to build a continuous media application with a dynamic QOS control scheme, and allocates processor capacity very efficiently without unexpected degradation of a media stream's quality.

Virtual resources (VR) in the form of interactive media applications (IMA), didactic videos (DV), interactive virtual platforms (IVP) or Small Virtual Resources (SVR), etc. are becoming powerful didactic tools in university teaching. This is particularly important in the case of engineering studies where these VR allow overcoming spatial visualization problems, learning mechanisms operation, etc., and increasing the student motivation in learning process. Thus, the understanding of complex concepts in engineering can be solved. In this paper, a review of the student opinion with regard to the use of diverse VR is presented. To achieve this goal, during the last years (2013-2015) different VR in diverse forms (IMA, DV, IVP and SVR) were used in teaching of engineering degrees at three different engineering schools. The opinion of students was collected in the form of surveys applied at the end of the course. According to obtained results, students considered very useful the use of VR in teaching/learning. However, they do consider them necessary as a complement of the teacher master class. In addition, from students' surveys, an estimation of the time distribution for each teaching activity can be draft which provides useful information for adapting the teaching of engineering studies.
