Users of public-access television stations may participate at most levels of this structure to make content of their choosing. Generally, anyone may have their programming aired on a public-access television channel. Users are not restricted to cable subscribers, though residency requirements may apply, depending on local franchise agreements or facility policy. Many public-access television channels try to favor locally produced programs while others also carry regionally or nationally distributed programming. Such programming—regional, national or even international—is usually aired on a channel curated by the PEG operator, which also carries programs produced by professional producers. A show that originates outside the municipality is often referred to as "bicycled", "dub and submit", or "satellite" programming.
