This paper proposes a novel decision QoS (Quality of Service) model for multipath transmission based on Markov model. Specifically, the model consists of three units: information acquisition unit, computing unit and decision-making unit. The responsibility of information acquisition unit is to collect status information of each path. Then the computing unit, the most critical unit, put the Mark off...
This paper firstly elaborates the video transmission quality evaluation methods, and gives an overall scheme of video transmission simulation and quality evaluation system, then based on the open-source network simulation software NS-2, realizing the the entire system, finally, simulation experiments are provided to demonstrate the feasibility of the system, the result shows that the video transmission...
Scalable video coding (SVC) is the extension of the H.264/AVC standard. Because of the variety of video transmission systems, storage systems and computing capabilities, video bit stream need to adapt the various needs of different terminals and network conditions, while SVC is a highly attractive solution to the problems above, it provides network-friendly scalability at a bit stream level with a...
Current educational presentations are commonly multimedia-based and with the realization of the mobile enterprise, accessing of such presentations stored on server from mobile devices will become increasingly common. This paper presents the results of our efforts with regard to the design and implementation of a client/server based mobile multimedia system for remote education. The system can automatically...
To adopt the methodology of literature analysis, questionnaire and mathematical statistics, this paper aims to investigate and analyze the College Physical education on the use of multimedia in teaching and analysis. The main conclusion is that: the overall level of the uses of the modern teaching tools in PE class is low. At this time, we should be aware of the importance of it in physical education...
Through some procedures, such as the questionnaire survey, documents collecting and scientific analysis, the present utilization of multimedia - CAI in university PE teaching is investigated and studied in this paper. The paper launches the elaboration in the perspectives of gym instructorspsila understanding, utilization and making of multimedia; and it explores education patterns adapted to the...
The paper introduces a method of Embedded Wireless Video monitoring System based on GPRS (General Packet Radio Service). First the S3C2410 platform is given based on the Embedded Linux, and the develop software environment on the platform. And then describe how to achieve the image collection on the platform, introduce the program of video capture, accomplish the JPEG (Joint Photographic Experts Group)...
