Quality of service provision in mobile multimedia - a survey

Abstract-Augmented Reality applications can serve as teaching tools in different contexts of use. Augmented reality application on mobile devices can help to provide tourist information on cities or to give information on visits to museums. For example, during visits to museums of natural history, applications of augmented reality on mobile devices can be used by some visitors to interact with the skeleton of a whale. However, making rendering heavy models can be computationally infeasible on devices with limited resources such as smart phones or tablets. One solution to this problem is to use techniques to Mobile Computation Offloading. This work proposes a mobile computation offloading architecture for mobile augmented reality. This solution would allow users to interact with a whale skeleton through an augmented reality application on mobile devices. Finally testing to assess the optimization of the resources of the mobile device when performing heavy render tests were made.

“…Several studies analyze multimedia data services [1][2][3][4][5][6][7][8] for a variety of communication media and devices. The process of providing real-time multimedia services over mobile and broadband Internet connection has different requirements in terms of the Quality of Service (QoS) [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27]. This prompts the division of multimedia data into two layers-the base layer and the enhancement layer.…”

Transmission Algorithm with QoS Considerations for a Sustainable MPEG Streaming Service

With the proliferation of heterogeneous networks, there is a need to provide multimedia stream services in a sustainable manner. It is especially critical to maintain the Quality of Service (QoS) standards. Existing multimedia streaming services have been studied to guarantee QoS on the receiving side. QoS has not been ensured due to the fact that the loss of streaming data to be transmitted has not been considered in network conditions. With an algorithm that considers the QoS and can reduce the overhead of the network, it will be possible to reduce the transmission error and wastage of communication network resources. In this paper, we propose a scheme that improves the reliability of multimedia transmissions by using an adaptive algorithm that switches between UDP (User Datagram Protocol) and TCP (Transmission Control Protocol) based on the size of the data. In addition, we present a method that retransmits essential portions of the multimedia data, thus improving transmission efficiency. We simulate an MPEG (Moving Picture Experts Group) stream service and evaluate the performance of the proposed adaptive MPEG stream service.

“…Mobile multimedia refers to a portable and mobile device, which is the integration of computer and video technique and the media for the information communication and dissemination of human-computer interaction with two types of media or above [1]. In the development of mobile terminal devices, there were more than 1 billion smartphone users in the world by the third quarter of 2012 and 354 million smartphone users in China by the first quarter of 2013, and China has surpassed America to become the country with most smartphone users in the world.…”

Abstract-with the continuous development of mobile communication technology, learners can easily take advantage of the fragmentary time to learn through smartphone and tablet PC due to their portability. We applied the mobile multimedia technology to the multimedia teaching of the ideological and political course, designed a mobile multimedia teaching platform for the ideological and political course, put forward the application of mobile technology to the ideological and political education for the first time. In addition, based on the frame of Ruby on Rails, we used HTML5 technology to enrich the functionality of the education platform, and adopted the online examination technology in the online examination section of the mobile teaching platform in order to help students evaluate their learning better and improve their learning efficiency. The teaching practice test showed that the excellent rate in the experimental group is improved obviously, reaching 10%; the good rate in the experimental group increases by 25% compared with that in the control group, and the number of people at medium and passing stages declines obviously: the medium rate decreases by 30%. These findings indicate the mobile teaching platform for the ideological and political course could improve students' learning scores significantly, which has a broad application prospect.
