TPG-8 can use any dynamic logo 100x100 pixels with 50 frames (PAL) or 60 frames (NTSC) as a test pattern.
TPG-8 comes with a test logo in shape of a white circle divided into 25 (or 30) sectors with 50 (or 60) frames. Each sector is coloured red for even frames and black for uneven frames. When the logo is displayed, it shows a ray, which "runs" over the circle and changes colour twice within each sector. This dynamic test logo allows to estimate the frame record speed and frame display rate in digital video recorders and surveillance systems. It helps to obtain the true, correct number of lost frames in digital frame relay and encoding/decoding process.
