“…[1], [2] The systems being investigated must address two very conflicting service requirements. First, as the mobile radio link is time-varying and subject to high hit error rates, it is not particularly well-suited to act as a bearer for multimedia services, which have high quality of service requirements.…”

Mobile communication channels are time-varying with respect to the available throughput and error conditions. This paper presents a centralised unicast architecture for use in multiparty communications. It is proposed to use object-oriented video coding to implement video prioritisation schemes and experiments are carried out to determine the perceptual quality improvements that can be achieved by varying the allocation of available source and channel protection bits to different video objects. Scene segmentation is also presented as a tool for increasing the throughput efficiency when transmitting encoded videoconferencing scene

“…In essence, the mobile user has the additional service of mobility. The combination of high data rates and mobility can lead to innovative new services like navigation [3]. These new services can also provide support to a mobile user who would normally be disadvantaged while been in transit between destinations or physically located outside of the normal working environment.…”

Abstract:Future 3 rd + generation mobile wireless systems are been designed to support high data rates in comparison to existing voice based wireless systems. The success of these new systems will partly be based on the data services it can provide. Apart from supporting traditional data (email, ftp etc.) & multimedia applications (videoconferencing, web access etc.), the combination of mobility and high speed data terminals will lead to innovative new data services e.g. navigation. In the PAULA project we are implementing an experimental distributed meeting service, based on Telepresence. The service attempts to compensate for the 'in transit' state of a mobile user by enabling them to attend a remote meeting while providing a high level of immersion, or sense of presence, at the meeting. The experimental system comprises of an omnidirectional camera placed in the meeting room that provides a constant navigable video stream to a remote mobile participant utlilising a Head Mounted Display.
