Due to the rapid improvement in resolution and codec, the number of video sensing device grows fast in the recent years. Tremendous data need to be stored and processed. To meet such a need, we developed a video hosting and processing platform for near-real time applications. An intelligent device can obtain connection-less upload function from our client-side SDK. Video data are sliced into pieces,...
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...
This paper proposes a new UPnP-compatible mechanism for enabling converged media streaming and playback services across multiple media devices in home networks. This mechanism design comprises three functional entities, including the UPnP AV media server, UPnP AV device controller, and converged media proxy. The functionality of this mechanism can accommodate heterogeneity of media content formats,...
HTML5 changes many aspects in the browser world by introducing numerous new concepts, in particular, the new HTML5 screen sharing API impacts the security implications of browsers tremendously. One of the core assumptions on which browser security is built is that there is no cross-origin feedback loop from the client to the server. However, the screen sharing API allows creating a cross-origin feedback...
The penetration ratio of broadband networks into residential areas increases rapidly by the wide distribution of Internet service providers and networks. People are able to distribute and play various media content with many types of networked multimedia devices for home multimedia entertainment in residential environments. This paper addresses a new idea of home-based IoT networks where home-networked...
In this paper, we propose a novel integrated API service system as well as a Web API script to enable mobile mashup application developers to invoke Web APIs in a consistent way, and provide a consistent format for the responses of Web APIs, thereby relieving developers of striving to study the usage of various Web APIs.
This study intends to establish a web-base learning and examination platform. Thought the S-P chart is chosen as the theoretical foundation, the analysis of data is expressed in a easily wording way to ensure an user friendly environment for students and teachers when using this platform. Both teachers and students can operate this platform easily and quickly to finish the examination and analysis...
Mobile devices today such as netbooks, tablet PCs and smart phones provide user-friendly interfaces for people to capture live video. However as a viewer, they prefer not to share downloaded clips due to the limited computing power, upload bandwidth and mostly due to the high power consumption while scheduling segments. In this paper, we discuss the possibility of allowing mobile clients run as free...
In the past, although mobile devices were equipped with multiple radio interfaces, for the sake of power saving, only one was activated for data transmission. The idea of concurrent transmission via multiple radio interfaces has not been seriously studied. However, nowadays, power consumption no longer is a problem in many application scenarios, e.g. VANETs. In this work, we investigate the performance...
The success of P2P file sharing systems inspired the development of P2P streaming systems for delivering online multimedia service in the last few years. The capacity of P2P streaming systems, i.e., how many peers can be concurrently serviced by the system, depends on system configurations including network bandwidth, overlay network formation, QoS constraints, membership management, peer selection,...
