A method includes processing error correction encoded data by a first processing chain of a transmitter. The processing includes interleaving a first portion of the error correction encoded data with respect to a first interleaving period to generate a first output signal. Interleaving the first portion includes de-multiplexing the first portion among multiple branches having respective delays in accordance with a distribution order and re-multiplexing delayed data from the branches to form the first output signal. The method includes processing the error correction encoded data by a second processing chain of the transmitter without use of interleaving to generate a second output signal. The method includes multiplexing the first output signal and the second output signal into a multiplexed stream. The method also includes transmitting the multiplexed stream from the transmitter over a communication channel to a receiver.

Broadcasting of digital video to mobile terminals

A method for communication includes encoding data using at least one Error Correction Code (ECC) to generate first and second output data streams. The first output data stream is processed to generate a first output signal, which has a first acquisition time. The second output data stream is processed to generate a second output signal, which has a second acquisition time that is smaller than the first acquisition time. The first and second output signals are transmitted simultaneously over a communication channel.
