Abstract
An application encoder generates independently accessible symbols and these symbols are aggregated by symbol aggregation means into a packet payload. The aggregated symbols in the packet payload are transported in a defined packet structure. These packets are transported over a channel by a packet transmitter that segments the packets into different segments by segmentation means. A segment receiver included in a first entity has the ability to detect whether a certain segment is lost and also knows the length of the lost segment. The segments are aggregated in the first entity to form at least one packet conforming to the packet stream. A symbol parser entity recovers the symbols and passes the individual symbols to an application decoder. The symbol parser in the second entity recovers, from the recovered non-lost information of each received packet, individual symbols.
