Abstract:
1. A method for providing unequal error protection to data packets in a burst transmission system, wherein each burst comprises a data section and an error protection section and wherein the data section of each burst comprises one or more data packets and the error protection section of each burst comprises error protection codes, and wherein the data packets are grouped based upon respective priority levels, the method comprising the step of providing error protection to each group of data packets based upon the respective priority level, whereas the error protection is provided by said error protection codes, and the method being whereby the steps of creating said error protection codes for each group of data packets using data of data packets of said group which are contained in the data section of two or more bursts forming a first set of bursts, and transmitting said created error protection codes in the error protection section of one or more bursts forming a second set of bursts, whereby the first set of bursts are disjoint from the second set of bursts.
