Multimedia Joint Viewing and Teleoperation is a new service for highspeed networks. It allows physically separated users to work in a collaborative fashion with documents and applications. It is however not a cooperative application but a system level service exporting the functionality of applications to many workstations.
Multimedia streams are difficult to transmit in full quality and real-time due to their size and constraints imposed by their timely presentation, Especially in slow channels with variable throughput-such as typical Internet connections-media streaming is extremely hard, We introduce a new iterative method for the transmission of media streams. The idea is… (More)
The Abstract Personal Communications Manager (APCM) is an Application programmers Interface (API) for telecommunications, providing simple and powerful interaction between communication applications and protocol software for circuit switched connections and transmission of voice and data. A few generic service primitives are developed through abstraction of… (More)
The Graphical Telephone Interface (GTI) is a screen-based telephony application for Telecommunication services. It provides an intuitive user interface to the myriad of services and features in state of the art communication systems such as the ISDN or a digital (ISDN) PBX. As a high end telephony user interface, GTI controls voice and data connections with… (More)
We introduce an original scheme that turns the World Wide Web (WWW) into a social place. Our vicinity-based approach is to show the Web's user space to the people surfing on the WWW. Being aware of other Web surfers, people browsing the Web may invoke synchronous communication by a single mouse-click – surfing the Web turns from a lonely affair into a joint… (More)
JPEG picture compression and related algorithms are not only used in still picture compression, but also to a growing degree for moving picture compression in telecommunication applications. Real-time JPEG compression and decompression are crucial in these scenarios. We present a method to significantly improve the performance of software based JPEG… (More)
