Distributing Content to Multiple Locations
Two kinds of networks for content distribution of every kind - Broadcast and CDN.
If you need to distribute the same content to multiple locations, you want a “broadcast” network.
This “one-to-many” network can deliver the same message simultaneously to any number of sites or deliver content that is targeted to specific locations.
Many information networks transfer information in such forms as text, sound, image, video, software, or combinations. Each line in the figure above delivers the appropriate content to each location. This content would be the same for each location in a broadcast network.
The origination point transmits precisely the same information so all can receive it in real-time.
Users must either be present at remote sites at the time of the broadcast, or have recording systems that permit later viewing.
If you need to transmit different content to different locations at different times, you'll want to use a "content distribution" network (CDN). The previous diagram still applies, but each stream of information can be unique.
Each added requirement impacts the configuration of the network, so the more we know about the purpose and specific content ahead of time, the better a satellite network can be configured for use.
