The television industry is by far one of the most dynamic sectors, with fast changing technology. Television is a huge industry with humungous number of people, processes, and technology working together for broadcasting a channel. Among the new technology trends in the sector, a turnkey playout server solution for broadcasting a single TV channel is at the forefront. It plays an important role in keeping the channel on air by having the major components of scheduling, ingest, playout, CG, and interactive graphics within one server, and is available in SD/HD/4K. It is a combination of software and hardware technologies. The output can be SDI or IP streaming, and suitable for applications including broadcast TV, internet TV, cable TV, etc.

Compared to a traditional architecture that requires multiple systems to do the equivalent functionality, channel-in-a-box is a single device with all the programs and news that integrate the necessary functionalities.

Let us now take a close look at the various elements.
