PROXY SERVER AND METHOD FOR DELIVERING INFORMATION IN A MULTIMEDIA COMMUNICATION SYSTEM

摘要

A proxy server (136) for a multimedia communication system (100), includes a receiver (240) receiving a multiplexed information stream transmitted from a source communication unit (402, 406) to a destination communication unit (406, 402); and a processor for de-multiplexing the received multiplexed information stream and extracting non-real-time data from the multiplexed information stream. The proxy server (136) further includes error detection means, operbly coupled to a transmitter and a memory element, for determining whether an error exists in the extracted non-real-time data. if an error is detected, then a non-real-time data re-transmission request is transmitted to the source communication unit. If an error is not detected then a copy of the extracted non-real-time data is stored in said memory element. A method (400, 500) for delivering a muliplexed information stream, a communication system and a storage medium are also provided. The multiplexed packed is forwarded immediately to the receiving node as well as being processed to see if there are any errors in the non-real time streams. This ensures non-real-time multiplexed multimedia streams are communicated with minimum delay in an end-to end communication link.
