These days most studios run their AoIP networks to produce audio content. In theory, keeping the studio’s contribution separate from distribution offers flexibility at all sites; and separating the audio portion from transmitting sources such as satellite, DAB+ or IP provides various benefits. Practically speaking, it’s now necessary to change perspective: IP offers broadcasters significantly more flexibility for the transmission of content, so more and more broadcasters and recording studios are deciding to expand IP-based networks. But broadband and fiber optic are growing at very different rates internationally. So in addition to the use of IP-based structures, flexible alternative distribution paths must be available. This leads to the question of how best to link contribution and distribution.
