AV over IP systems use encoders, decoders, and network switches to transmit audio and video signals over a standard IP network. This allows for a more flexible and scalable way to distribute AV content.
Encoders are used to convert analog audio and video signals into digital data, and then transmitting the data over the network. The data is then received by decoders, which converts it back into analog signals that can be displayed on a monitor or TV. Network switches are used to allow multiple encoders and decoders connection together.
