Abstract
Today's trend toward extensive on-the-spot live color broadcasting of news and sports events has pointed up the need for a highly mobile studio-performance color camera. Approximately two and a half years ago a system design was formulated with prime consideration given to the requirement for a compact, rugged, lightweight camera that would be highly mobile and still maintain the high performance and operational features of the studio-type camera. Its small size and light weight were made possible by improved circuit design and new state-of-the-art components and construction techniques. The following items were of particular importance in reducing the size and weight of the system: a 1-in broadcast quality Plumbicon pickup tube; a small-size, lightweight lens with elements of higher light transmission; specialized integrated and thick-film hybrid circuits; computer-type digital control circuits; high-density multi-layer printed circuit cards; and multiplexing techniques enabling the use of triaxial cable
