Abstract
A method and apparatus for efficient multimedia data interchange which utilizes multimedia pacing in a distributed data processing system. During a multimedia communications session, each of a plurality of receiving stations transmits multimedia pacing requests to a sending station at negotiated set time intervals. The multimedia pacing request includes information on the availability of current storage for multimedia data at the receiving station, a minimum data time remaining in storage in the receiving station and other information pertaining to the interchange of the multimedia data. The sending station then allocates various priorities to the transmission of data to the plurality of receiving stations in an order indicative of the type of data, i.e. multimedia or non-multimedia, and the information in the multimedia pacing request pertaining to the minimum data time remaining in storage at the receiving station. In addition, the sending station periodically determines the availability of the transmission queue. When the transmission queue is not readily available, the sending station transfers only high priority multimedia data to the transmission queue; however when the trans…
