A broadcast domain is a logical network segment in which any computer or other device connected to the network can directly transmit to any other in the domain without having to go through a routing device, provided that they share the same subnet and gateway address and are in the same VLAN, default or installed. A network segment is a portion of a computer network separated by a computer networking device, including: Repeater or hub (both OSI layer 1 devices) Bridge or switch (OSI layer 2 devices) Router (OSI layer 3 device) A bridge separates collision domains while a router separates both collision domains and...

A very basic network that uses hubs rather than switches or routers is like a post office clerk checking the mail. One clerk looks at each letter to confirm that the mail is not for himself or herself. When one letter (signal) is sent from one point, all the other points in the network will have to check in order to confirm that the letter (signal) is not for themselves. Routers and Layer-3 Switches are used to segment broadcast domains.
One of the many compelling reasons to oppose the WIPO broadcast treaty in its current form is that it wraps another layer of property rights around works that are broadcast.
Broadcasters, when asked why they need an additional IP right in the signal, often talk about the investment they make in finding the programming, arranging and scheduling it.
