Claim Text:
1. An error correcting encoder comprising: an error correcting data generator that receives payload data belonging to a first category (first category payload data), that receives payload data belonging to a second category (second category payload data), that determines first error correcting data for the first category payload data, and that determines second error correcting data for the second category payload data; and an interleaver that interleaves at least the second error correcting data and the second category payload data with each other, wherein a first interleaving length relative to an interleaving of the first error correcting data and the first category payload data is different from a second interleaving length relative to the interleaving of the second error correcting data and the second category payload data; wherein the first category payload data corresponds to a base layer and the second category payload data corresponds to an enhancement layer of a scalable video coding (SVC) scheme or a multiview video coding (MVC) scheme; the error correcting data generator receives the first category payload data and determines the second error correcting data based on the first category payload data and the second category payload data so that a decoder-side error correction of the first category payload data using the first error correcting data and the second error correcting data, improves an error correction performance for the first category payload data compared to using the first error correcting data only; and the error correcting encoder further comprises a delay that delays the first category payload data and the first error correcting data so that when all symbols of a first source block of the first category have been received, also all source symbols of the second category of a second source block corresponding to the first source block have been received.
