Developing Real-Time Multimedia Conferencing Services Using Java And Sip, Gavin Byrne, Declan Barber
Developing Real-Time Multimedia Conferencing Services Using Java And Sip, Gavin Byrne, Declan Barber
The ITB Journal
This paper examines Java's suitability in creating real-time multimedia communications-based applications in Next Generation Networks (NGNs). We investigate some of the current enabling technologies provided by the Java plaiform which are concerned with the rapid development of realtime communications-based products and services. In particular, we look at creating a multiparty conferencing and collaboration service using the Session Initiation Protocol (SIP) and the JAIN Framework and present an approach which models multiparty conferencing applications by separating signaling and media transfer functionality. We map our model through the design stage to an implementation in Java. This paper is based on real experiences …
Developing A Distributed Java-Based Speech Recognition Engine, Tony Ayers, Brian Nolan
Developing A Distributed Java-Based Speech Recognition Engine, Tony Ayers, Brian Nolan
The ITB Journal
The development of speech recognition engines has traditionally been the territory of low-level development languages such as C. Until recently Java may not have been considered a candidate language for the development of such a speech engine, due to its security restrictions which limited its sound processing features. The release of the Java Sound API as part of the Java Media Framework and the subsequent integration of the Sound API into the standard Java development kit provides the necessary sound processing tools to Java to perform speech recognition. This paper documents our development of a speech recognition engine using the …
Voice Activated Command And Control With Speech Recognition Over Wireless Networks, Tony Ayres, Brian Nolan
Voice Activated Command And Control With Speech Recognition Over Wireless Networks, Tony Ayres, Brian Nolan
The ITB Journal
This paper presents work conducted to date on the development of a voice activated command and control framework specifically for the control of remote devices in a ubiquitous computing environment. The prototype device is a Java controlled Lego Mindstorm robot. The research considers three different scenario configurations. A recognition grammar for command and control of the robot has been created and implemented in Java, in part in the recognition engine and in part on the robot. The physical topology involves Java at each node endpoint, that is, at the handheld PC (iPaq), the PC workstation, the Linux server and onboard …
Towards A Framework For Modelling Multimedia Conferencing Calls In The Next Generation Network, Gavin Byrne, Declan Barber
Towards A Framework For Modelling Multimedia Conferencing Calls In The Next Generation Network, Gavin Byrne, Declan Barber
The ITB Journal
This paper is concerned with the creation of a multiparty multimedia conferencing application which can be used in Next Generation Networks. It begins by suggesting ways in which conferencing can be modeled with a focus on separating signaling and media transfer functionality. Enabling technologies which could support the modeling framework derived and which are compatible with Next Generation Network (NGN) principles are reviewed. Finally, a design and implementation for a simple multimedia conferencing application are described.
A Java Framework For Computer Vision, Stephen Sheridan
A Java Framework For Computer Vision, Stephen Sheridan
The ITB Journal
This paper outlines a framework implemented entirely in Java that attempts to give students exposure to computer vision systems from a practical standpoint. Various tools and technologies are introduced that will allow a student to acquire an input image through a WebCam, extract useful information from that input image and finally, attempt to make sense of the input.
Initial Experiences Gained And Initiatives Employed In The Teaching Of Java Programming In The Institute Of Technology Tallaght, Eamonn Hyland, Gary Clynch
Initial Experiences Gained And Initiatives Employed In The Teaching Of Java Programming In The Institute Of Technology Tallaght, Eamonn Hyland, Gary Clynch
Conference Papers
This paper describes recent experiences gained and initiatives employed in the teaching of Java programming to first and second year students in the Institute of Technology Tallaght from September 2000 to March 2002. It outlines some elearning, technological and pedagogical initiatives that were undertaken within the department and the resultant preliminary outcomes. The outcomes have been determined after detailed analysis of the results of a survey which was commissioned to determine the effectiveness of the initiatives and also to identify those parts of the Java language which were causing students particular difficulty. The students surveyed are currently completing their fourth …
