Abstract

An error protection tool comprises: a separator configured to divide at least one frame of data into classes of data according to error sensitivities of the data in the classes. An encoder is configured to perform different types of error coding on the classes of data to provide them with unequal error protection capabilities. An interleaver is configured to rearrange the classes of encoded data so that a data class being more protected is arranged at equal intervals in a data class being least protected.

Claims (8)

1. An error protection tool comprising:

a separator configured to divide at least one frame of data into classes of data according to error sensitivities of the data in the classes;

an encoder configured to perform different types of error coding on the classes of data to provide them with unequal error protection capabilities;
and an interleaver configured to rearrange the classes of encoded data so that a data class being more protected is arranged at equal intervals in a data class being least protected.
2. An error protection tool according to claim 1, wherein the classes are defined by categories of error sensitivities.
3. An error protection tool according to claim 1, wherein each class is correlated to one type of error coding.
4. An error protection tool according to claim 1, wherein one type of error coding is no error coding.
5. An error protection method comprising:

dividing at least one frame of data into classes of data according to error sensitivities of the data in the classes;

performing different types of error encoding on the classes of data to provide them with unequal error protection capabilities; and rearranging the classes of encoded data so that a data class being more protected is arranged at equal intervals in a data class being least protected.
6. An error protection tool according to claim 5, wherein the classes are defined by categories of error sensitivities.
7. An error protection tool according to claim 5, wherein each class is correlated to one type of error coding.
8. An error protection tool according to claim 5, wherein one type of error coding is no error coding.
