Screen 8

Screen 8 occurred on July 29th, 2019.

Analyzing The Spectrogram
The screen had some sporadic noises playing in the background, using a spectrogram visualization tool to analyze these noises, a string of text can be read:

"| C+ || +33 || 1997 - 2010 || 768 || KUDELSKI || CORRECT || ROT |"

The Distorted QR codes
The screen shows a distorted QR code spinning, in each full rotation the QR code changes to a different one, there is a total of 9 QR codes.

Some of the hints of the spectrogram are used to find the correct decryption tool and to give the correct decryption settings: The QR codes have the colors of the middles inverted, so they have to be corrected before scanned. The CORRECT hint is about that. After scanned and ordered by screen appearance, they form the text:
 * KUDELSKI Group is the creator of Nagravision, an encrypting system responsible for encrypting digital cable or satellite television channels so only paying users have access to them. The QR codes are encrypted with Nagravision, the most user-friendly decryption software for Nagravision is called Cryptimage.
 * C+ stands for Canal+, a French TV channel (France number code is +33) that used Nagravision for encryption and that adopted the primary table 2 of Nagravision from 1997 to 2010.
 * In Cryptimage, using "Nagravision Syster" decryption with the primary table 2 and the dimensions 768x576 generates a clear video of the QR codes.

“7g1r h5 m0s vg4s x0t sg1mj h7 l19gs 8d”

The Answer
Applying ROT-1 in the text end up giving:

“7h1s i5 n0t wh4t y0u th1nk i7 m19ht 8e”

Which is the Leet for: “This is not what you think it might be.”

Therefore our answer is 7h1s _i5_n0t_wh4t_y0u_th1nk_i7_m19ht_8e
