Sound-in-Syncs : ウィキペディア英語版 | Sound-in-Syncs Sound-in-Syncs is a method of multiplexing sound and video signals into a channel designed to carry video, in which data representing the sound is inserted into the line synchronising pulse of an analogue television waveform. This is used on point-to-point links within broadcasting networks, including studio/transmitter links (STL). It is not used for broadcasts to the public. ==History== The technique was first developed by the BBC in the late 1960s. In 1966, The corporation's Research Department made a feasibility study of the use of pulse-code modulation (PCM) for transmitting television sound during the synchronising period of the video signal. This had several advantages: it removed the necessity for a separate sound link and offered improved sound quality and reliability.〔Pawley, E (1972). ''BBC Engineering 1922-1972'', pp. 506-7, 522.
