The Color Bar signal is generated with unconventionally slow rise and fall time value to facilitate video level control and monitor color adjustments of HDTV and SDTV equipment. Digital test images generated following the RP 219:2002 specifications and adapted to perfectly fit 114 standard and non-standard resolutions for both 16bpp and 8bpp ...
Test cards typically contain a set of patterns to enable television cameras and receivers to be adjusted to show the picture correctly (see SMPTE color bars).Most modern test cards include a set of calibrated color bars which will produce a characteristic pattern of "dot landings" on a vectorscope, allowing chroma and tint to be precisely adjusted between generations of videotape or network feeds.
EBU 100/0/100/0 Colour Bars Displayed colours are only approximate due to different transfer and colour spaces used on web pages and video (BT.601 or BT.709). An alternate form of colour bars is the 100% Colour Bars or EBU 100/0/100/0 Colour Bars pattern (specified in ITU-R Rec. BT.1729 [8]), also known as the RGB pattern or full field bars, which consists of eight vertical bars of 100% ...

SMPTE color bars as seen in calibration mode (blue channel only). The large bars are well matched to the smaller segments underneath, showing that the chrominance and luminance components are adjusted correctly. Based on color SVG version (GFDL).
At the centre bottom of the test card is an animated grey bar with graduations corresponding to 1/12 of a second. The animation is accompanied by a 'pip' that occurs when the animated bar reaches the centre mark (indicated by a 0), which together can be used to determine whether the digital audio and video signals are synchronised.
