television and video test patterns

Sundry video and television test patterns, star targets, gradients and moire charts for checking frequency, resolution, broadcast fidelity, color fidelity, shape integrity and to identify the station when it was not broadcasting programs. Some test images included teletext information including time and date.

  1. The 6th one down, where did you find it? That's an artistic rendition based on the old RCA one but not identical to it. Thanks, Bluejay Young, twitter @ksol1460

    1. No idea where it came from; this was just a collection that grew over time, hence the distinct lack of detail. They really should be captioned. Thanks for the enlightenment!
