The BBC and ITV have over the years used a number of tuning signals, test cards and captions either for engineering purposes, or just to fill time in the days before breakfast and daytime TV. This page shows some of them, and some of the captions used in days past.

We can now provide some music whilst you watch, The Gallery Theme from Vision On! Alternatively, Mike Brown can tell you about a CD containing some of the best Test Card Classics.

	First, A Little Bit of History
	An introduction of sorts, to early television, and how test cards began.
	BBC Tuning Signals and Test Charts
	Used from the beginning of the BBC until the early seventies, the tuning signal was primarily for viewers to warm up their television sets and adjust the numerous controls until they could see an acceptable picture. The images and patterns were for use by "lay-people" and were not designed to test equipment in any scientific way.

	ITA and IBA Test Cards and Tuning Signals	11 Apr 98
	From 1955 the ITA, and its successor the IBA used numerous test cards and tuning signals, some were variants of those used by the BBC, others like the classic "Picasso" tuning signal were entirely original.This section shows a selection of them.
	BSB Test Cards
	The innovative satellite service was very short-lived, merging with Sky Television in 1990. Each channel had a unique themed test card, brought back to life here.
	Pictures from around the World	05 Oct 97
	It is perhaps to be expected that having given birth to Television, that British Test Card designs should be exported all around the world. This section shows some of the variants of the classic BBC test cards used globally, plus also some of the native variety used in North America and Ireland.
