Our system consists of a Blackmagic Design ATEM Television Studio HD 8-channel switcher. The switcher has 3 cameras, a computer that runs PowerPoint, and an audio signal from the audio console. All those signals are combined into a single SDI (Serial Digital Interface) signal. A PC Laptop, running OBS (Open Broadcast Software) takes the signal and connects it to the streaming platforms of YouTube Live and FaceBook Live (In the following ). The laptop does not accept SDI inputs, so the AJA U-TAP SDI takes the SDI output from the Blackmagic switcher in real-time and converts it to a USB signal that the laptop accepts.
We’ll take a look at each component as we go forward.
