Visuals: On a cyan background, a brown circle zooms in before turning yellow. It then splits in half in a wavy form (forming the s) and the halves move slightly apart, also stretching the right side of the circle a bit. A television shape draws itself around it with a curve on the top right corner and 2 different lines sticking out from the top right corner, forming the logo. 6 lines, 2 green, 2 red and 3 blue appear from either side of the logo and zoom towards the front/sides of the screen before fading out and reappearing. After that, the textČESKOSLOVENSKÁ
