Apparatus and method for encoding and decoding signals

New capabilities will allow conventional broadcast transmission to be available to mobile devices. A method is described including receiving a data set, extracting a subset, encoding the subset using a first encoding process, combining the encoded subset with the remaining portion, and encoding the combined data set including the appended subset using a second encoding process. an apparatus is described including means for extracting a subset, means for first encoding, means for combining, and means for second encoding. An apparatus for decoding includes a data identifier receiving a data set and identifying a subset of data, a first decoder decoding the subset using a first decoding process, and a second decoder combining the subset of data with a remaining portion of the data set and decoding the combined data using a second decoding process. A method for decoding is also described.
