|Chromatic difference signal output level (Pb, Pr)||(-350~350)mV||±(2%X+6mV)|
Annex 1 Methods of system software
RDL-100 Video Signal Generator System Control Software V1.0 Operating Instructions.
Write the purpose
The purpose of this document is to introduce the operating instructions and operation steps of the RDL-100 video signal generator system control software V1.0 for easy user use.
The RDL-100 video signal generator system control software V1.0 is opened displays the main control and display interface in Figure 1, including 10 controls of Time, Pattern, Pixel, Audio Freq, Audio Level, Preview, Play, Signal, Minimized, and Closed.
The control is shown in Figure 2 to display the video format for users to choose, and the interface is shown in Figure 3.
The Pattern control
The control in FIG. 4 serves to display the video test signal for the user to choose.
The control is shown in FIG. 5, which is to display the pixel sampling mode for users to select, and click the interface in FIG. 6.
The Audio Freq and the Audio Level controls
The control is shown in FIG. 7 to set the frequency and level of the accompaniment.
The Preview control
The control is shown in FIG. 8 to preview the selected video signal for the user reference.
The control is used in FIG. 9 to play and stop playing the video signal. When the button is playing the video signal, stop playing the video signal when the button is extinguished. When playing the video signal, the Time, Pattern, Pixel, Audio Freq and Audio Level controls are prohibited, and the interface is shown in FIG. 10.
The Signal, Minimized, and Closed controls
The control appears in Figure 11. The Signal control has no substantive effect, and the Minimized and Closed controls function to minimize the interface and close the software, respectively.
Three Vertical Bar Signal IEC62368 Three Vertical Bar Signal
Three vertical bar signal’ shall be used as defined in 220.127.116.11 of IEC 60107-1:1997
3.2.1 .3 Three vertical bar signalE.L. IEC 60238 A1 2017 2018-04-03.doc
The three vertical bar signal produces three equidistant vertical white bars on a black background. The width of each bar is 1 /6 times the nominal horizontal width ( W ) of the picture.
A line-time waveform of the signal is shown in figure 9. This signal has an APL of 50 % and includes the reference white level. It is suitable for setting the output signal level and the luminance level of white For the SECAM measurements, the subcarrier with the frequency and amplitude corresponding to black and white is superimposed on the signal.
The same bar width can be applied for the wide aspect ratio picture.
