This technique, known as "channel coding", is essential for broadcast or recorded digital systems to maintain bit accuracy.
Forward error correction and timing information is applied to these substreams such that the original stream can be reformed using at least all but one of the substreams (fountain codes are an efficient way to make and combine the substreams).

Ultimately, channels become so optimized they are operating at the extents of their physical limitations, and in these cases, improving reliability is done by adding Forward error correction (FEC) also known as Error Correcting Code (ECC) capabilities that trade the overhead of transmitting extra information with the advantage of being able to correct errors during transmission.
