Abstract
Some media applications use media that contains multiple types of media components in it and media sources with access to this media must send each type of media component to one or more media rendering destination devices. Furthermore there may be multiple destinations that can receive a particular type of media component and the media must be received at each destination without losses. This invention describes a two tier packet buffer structure at the media source with primary and virtual packet buffers that ensures minimal memory use at the media source and minimal network use. Furthermore the use of a sliding window with each virtual packet buffer associated with each destination, independently keeps control and track of destination state, ensuring the correct receipt of media data at each destination.
