Video/Multimedia

The project aim is to port and install an audio conferencing tool on JORNADA 568 and try the audio conference within the Jornada (using the IEEE 802.11 interface) and with a remote workstation connected to the wired network. As project results a report is expected. The report should contain the details on the installation and a set of performance measurements of the video/audio conference reporting the application behavior using the End-to-End delay and the loss rate vs. the codec type and the network load.

Optional:
(a) repeating the experiment using the Linux OS environment (to be installed in the jornada if possible);
(b) Study if is possible to connect the audio conference client for Jornada to an H.323-PSTN gateway in order to make a phone call from the jornada to a campus number.

Multimedia Streaming for Wireless Equipments

The project aims to develop an application that provides audio and video streaming to Pocket PCs and Laptops and other wireless enabled devices, over WLAN. The application would support both 802.11a and 802.11b and also the new 802.11g standards. The application would take a live video/audio input and then transmit the data to the applications running on the wireless enabled devices. The main issue that troubles every other streaming application running on WLAN is the limited availability of bandwidth. Controlling the bandwidth requirement for these applications would be the main issue addressed in this project. Various techniques would be tried, such as, devising new compression algorithms for video streams, using motion jpegs, intermittent dropping of frames, etc to reduce the bandwidth requirements but at the same time maintain the quality of the video.

Mobile Graphics - Scalable Vector Graphics (SVG)

SVG (Scalable Vector Graphics), which has been developed by W3C, is a new standard for two dimensions vector graphics. SVG was written in XML and usable as an XML namespace. SVG contains six main types of graphic object: vector graphic shapes (include line, polyline, polygon, path, ellipse, circle, rectangle), images, gradient fills, filters, reusable components such as symbols and markers, and text. "Graphical objects can be grouped, styled, transformed and composited into previously rendered objects. The feature set includes nested transformations, clipping paths, alpha masks, filter effects, template objects and both procedural and declarative animation". SVG has rich set of event handler make it interactive.

SVG can be used in Graphics Design; Location-Based Services such as traffic and weather reports; Mapping and Positioning, that's useful for navigating; Animated Picture Messaging; Multimedia Messaging include voice, video, animation and interactive graphics; Entertainment; Industrial Applications; eCommerce and User Interfaces.
