Abstract
A data stream to be communicated over a plurality of channels is divided into blocks (A1,B1,C1,D1,A2,B2, . . . ), and each successive block is transmitted along a different channel (A,B,C,D) on a cyclic basis. To reduce or eliminate the possibility of undetectable errors occurring owing to noise affecting all channels simultaneously and thereby corrupting data in several successive blocks propagating in parallel through the channels, the blocks in at least one channel (A,B) are offset in time relative to the blocks in another channel (C,D). In the case of four channels, such as four-conductor cable, the blocks on two channels are offset by half the length of a block relative to the blocks on the remaining two channels.
