Interconnect consisting of two wires. One wire transports the luminance signal while the other transports the multiplexed chrominance signals. This system allows efficient dubbing between recorders because recorders normally record the luminance on one tape channel and the two colour difference signal on a single channel. To record the two-color difference signals on a single channel, the two-color difference signals are compressed and then multiplexed together. Transferring the two video signals between tape recorders in the two-wire format prevents the two tape recorders from having to do additional signal processing.
