Methods and apparatus for processing information, e.g., audio, video or image information, for transmission in a communication system are disclosed. In an illustrative embodiment, a multiple program coder encodes a bitstream for each of the programs, in accordance with a specified bit allocation. An outer code encoder receives the encoded bitstreams from the multiple program coder, and jointly applies an outer code, e.g., a CRC code, RS code, BCH code or other type of linear block code, to subblocks of a subset of the resulting encoded bitstreams. The outer code is applied such that subblocks of each of the encoded bitstreams in the subset of the encoded bitstrcams are associated with a single outer code block. The number of subblocks associated with a given outer code block may be an integer or non-integer number of code blocks. The invention allows a designated number of program subblocks to share a given outer code block, such that outer code error flags can be generated for smaller groups of bits per program than would otherwise be possible. An inner code encoder may be used to apply an inner code, e.g., a convolutional code, turbo code or trellis coded modulation, to the resulting outer code blocks.
