Abstract :
Future engineering objectives for each of the parts of the transmission chain are forecast. they include smaller cameras with higher sensitivity (possibly using solid-state sensors), flying-spot film scanners operating on both the 625/50 and 525/60 standards, automated signal switching systems, improved recording systems using high-density magnetic and laser techniques, the use of p.c.m. for television links (which may employ optical fibres), and solid-state receiver displays.
