Abstract: Despite the success of MPEG-2 Transport Stream (TS) being used to deliver services in broadcast channels, the increase of ondemand viewing of multimedia content over IP with browser-centric media endpoints introduces a new requirement for more individualized and flexible access to content. This has resulted in alternatives to MPEG-2 TS. While the needs of interactive broadcast services (such as personalized advertisement or selection of audio stream with a language suitable for a specific user) grow there is an active standardization work under going for the next generation broadcasting systems. To best enable a complete system of hybrid broadcast and broadband services, Advanced Television Systems Committee (ATSC) 3.0 has developed an enhanced broadcast transport method named Real-Time Object Delivery over Unidirectional Transport (ROUTE)/DASH for delivery of DASH-formatted content and non-real time (NRT) data. Additionally, for broadcasting, ATSC 3.0 has also adopted MPEG Media Transport (MMT) standard, which inherits major advantageous features of MPEG-2 TS and is very useful in real-time streaming delivery via a unidirectional delivery network.This paper mainly describes features and design considerations of ATSC 3.0, and discusses the applications of the transport protocols used for broadcasting, i.e., ROUTE/DASH and MMT, whose comparative introductions are also presented in details.
