The colour broadcasting standards now in use, NTSC, PAL and SECAM, are conventionally referred to as being composite systems. This word is used to differentiate between such systems, which only use one signal path for transmitting a colour picture, and the alternative of the three paths required for the separate transmission of red, green and blue primary signals. The use of a single path for conveying a colour signal made the system compatible with monochrome for operations in studio centres.
