C'est pas sorcier -DE LA CAMERA AU TELEVISEUR : Le voyage de l'image

The official channel of the France 3 program. It's Not Rocket Science, the science and discovery magazine. A dozen cameras, kilometers of cables, a control room for lighting, another for sound, a satellite station that transmits the images across France... Fred and Jamy are on location filming the 35-hour live broadcast of the Telethon. They explain the routes the television images take before reaching us. How does a camera work? What does a sound engineer do? What is a satellite station? How does it transmit the images? And what exactly happens inside our screens?
