The playout server functions as the "heart" of the broadcast chain, automating the continuous transmission of video content according to a pre-defined schedule. It eliminates the need for manual intervention (such as loading tapes or playing files manually) by dynamically fetching, decoding, and broadcasting media assets from a storage array. playout server
