Abstract
Broadband multimedia communications will be a key element in the 3rd generation of wireless services. A primary challenge is the support of interactive services requiring synchronous playout of multimedia content with a maximum acceptable delay in a multi-user scenario. Subjective tests show that the subjects prefer a lower quality reproduction than a “hopping” video: the pause needed to re-buffer severely affects the overall quality. To maximize the number of active users that can be served with a predefined Quality of Service (QoS) level by a packet-oriented radio access, we propose the use of a multimedia proxy. This component may transcode the original video stream to match a predefined quality level based on the quality of each user’s channel.
