Some possible delivery systems for video programs are:
- Radio broadcast frequency
- Coaxial cable
- Satellite
- Optic fiber
<h3>Which program delivery methods work the best?</h3>
The first technologies for distributing videos to the general public were historically terrestrial broadcast TV systems. Following these systems naturally and with great success were cable and DTH (direct to home) satellite technologies.
In the past, these systems have been installed on-site using hardware, networks, and other links that were especially created for the purpose of transmitting video feeds between various facilities and entities in the supply chain.
Therefore, These are the five different ways that learning is delivered: face-to-face instruction, virtual classrooms, online learning, blended learning, and mobile learning.
