What is the ending song of CSI Miami Season 9 Episode 8 called

Test chart. For maintenance. Test whether the color of the broadcast signal of the TV station is normal.

In the past, this standard TV signal was often composed of color blocks, dense stripes, frames and circles, so we called it a globe map, which can be used by experienced people to adjust, identify and repair TV sets.

Basically, the TV test signal (even if it is generated by the equipment used by the TV manufacturer) is much the same.

1. Black and white rectangular border guard This is used to adjust the amplitude of line and field scanning and the center position of the image. The aspect ratio of the test chart is the same as that of a color TV screen, which is also 4:3, so it can be used to check the aspect ratio of the TV, and the vertical bezel is used to check the synchronization separation and clamping.

2. The gray background and white grid background are in the border protection frame, except for the large circle figure and the rectangular color bar signal around the circle, which are composed of the white line square pattern on the gray background. It has 13 tiles horizontally, 17 tiles vertically, and a gray background brightness of 30 for black to white, allowing it to check geometric distortion, nonlinear distortion, dynamic convergence, and color purity.

3. Circle, which is used to check geometric distortion and nonlinear distortion.

4. Signals in the circle, there are 9 kinds of test and flag signals in the large circle of the color TV test chart, which are arranged in order from top to bottom

a Television station logo, which indicates the name of the television station broadcasting.

b represents the standard skin tone of Chinese, which can be used as a reference when adjusting the hue, color saturation and brightness of the TV.

c Black and white square wave to check the transient response of the brightness channel of the TV.

d The color signal has 6 color bars below the gray band, and they are arranged in the order of yellow, cyan, green, purple, red, and blue. It gives the TV viewer a general impression of color, and uses it to adjust the hue and color saturation, and also to check whether the automatic achromatic circuit of the TV is working properly.

e White center crosshair, white center crosshair on black background, horizontal white line width 1 line, a total of 2 lines; There is 1 vertical white line in the middle, and 5 symmetrical lines on each side, a total of 11 lines. Used to determine the center position of the entire image, check interlacing, and static convergence.

f Clarity line There are 5 levels of line. It is located below the inner station logo and skin color symbol of the large circle, and it is used to observe and adjust the sharpness of the TV, the bandwidth of the color saturation part, and the locking relationship between the subcarrier and the line frequency.

g Gray scale, below the sharpness line, there is a horizontal band that gradually changes from black to white, which is a test band for measuring gray level. This test strip is divided into 6 levels according to the amplitude of the electrical signal, and the linearity and white balance can be checked and adjusted.

h The white rectangular block is used to check for high-frequency reflections due to poor antenna or cable matching, etc.

i Standard time marker, with Beijing Standard Time broadcast in a black rectangular block on a white background for the viewer to use in time.

J Color signal around the circle There is a square on each of the four corners of the outer border of the test chart, each with a certain brightness and color saturation value. It is used to check the working performance of the color decoder.

Set in Miami, Florida, this series focuses on local investigators, describing how they solve one unsolved crime after another with the help of high-tech and meticulous traditional methods. The crime scene investigation team under the Miami Crime Forensic Bureau frequently goes to various crime scenes to look for evidence and clues, and the team members use the most advanced scientific and technological means to piece together the seemingly meaningless clues into irrefutable evidence, and reconstruct the case through the cocoon, so that the criminals have nowhere to escape ......

The Miami Forensic Crime Bureau is headed by a former ** detective and leads several subordinates: bilingual bomb disposal experts, investigators, DNA supervisors, coroners and diving experts to continue to solve criminal cases. The members of the new scientific monitoring team worked closely together, and after their methodical analysis, with the help of high technology, they were able to complete the task successfully.

In addition to the new actors, the new series has added outdoor and search scenes, rather than just laboratory scenes, to refresh the audience.
