Abstract

ANS method for transmitting data, in which basic data is transmitted while one or several packets are transmitted with data that complements the basic data and increases the quality of the basic data when being decoded by a receiver. The packets contain at least one field with information about how the complementing data of the respective packet increases the quality of the basic data. The field can be read independently of the complementing data of the respective packet. Based on the information, a decision can be made as to whether the packets are to be forwarded or decoded.
