TVE test card
A Danish-designed test card used by Spanish television for decades.
The TVE colour test card was an analogue television test pattern used by Televisión Española after it began PAL colour broadcasts in 1975. Its distinctive look came from Danish engineer Finn Hendil (1939–2011), who created it in 1973 under Erik Helmer Nielsen at the Philips TV & Test Equipment lab in Amager, south of Copenhagen—the same group behind the Philips PM5544 pattern. It took over from an earlier black-and-white version by Eduardo Gavilán.
This test card was treated as a regular part of the TV schedule, appearing in daily program listings in newspapers and magazines. On some days it was reportedly the most-watched program, as people left their sets on while waiting for afternoon broadcasts to begin. It also became a visible marker of general work strikes, when it would air in place of normal programming, signalling the strike’s success. The card appeared on several TVE channels, including TVE 1, TVE 2, Canal Clásico, Teledeporte, and TVE Internacional.
As TVE channels moved to 24-hour broadcasting, the test card was gradually retired. It stopped airing on La Primera in 1996, and on La 2 in the early hours of 6 January 2001, though it continued sporadically on Teledeporte and TVE Internacional until 2005.
**Operation and features**
Because TVE adopted the PAL colour system in 1975, the test card includes specific elements for adjusting colour. Since it came from the same team that made the Philips PM5544, it shares many features—like colour and grey bars and castellations—but also has differences, such as different resolution gratings and a coloured background rectangle and circle.
Two generations of the card existed. The original used a heavily modified PM5544 that showed the station name at the bottom of the circle via a programmable character generator. From the early 1990s, the card’s appearance changed: the station name became a graphic, and the clock font matched that of the PM5644 (which was then available, likely explaining the changes), suggesting the original hardware was replaced.
**Castellations**
The alternating white and black boxes around the edge are called castellations. They help set overscan (the castellations should be visible) and check the low-frequency response of the entire transmission chain.
**Grid**
The background has a grid of perfect squares made from 100% intensity white lines. This allows:

Lore & Background
The TVE test card was generated by a heavily modified Philips PM5544, which displayed the station name at the bottom of the circle using a programmable character generator. From the early 1990s onward, the appearance changed: the station name became a graphic, and the clock font became identical to that of the PM5644, likely because the original hardware was replaced. The test card was considered part of the regular TV schedule, appearing in daily program listings in newspapers and magazines, and was said to be the most viewed program on some days as people watched it while waiting for afternoon broadcasts to start.
Reader's Guide
The TVE test card was significant as a technical tool for calibrating colour television receivers and as a cultural marker in Spain. It allowed technicians to adjust geometry, convergence, focus, colour purity, chrominance delay, and frequency response using elements such as castellations, a grid, an orange rectangle, a light blue circle, colour bars, greyscale bars, and grating bars. Beyond its technical role, the test card became a visible sign of general work strikes, when it was broadcast in place of regular programming, marking the strike's success. It was used on multiple TVE channels including TVE 1, TVE 2, Canal Clásico, Teledeporte, and TVE Internacional, and was phased out as continuous 24-hour broadcasting began, ceasing on La Primera in 1996 and on La 2 in early 2001, though it continued sporadically on Teledeporte and TVE Internacional until 2005.
