This standard describes methods for adapting signals for carriage via the extensible data transfer protocol defined in the IEEE P3420 Standard for Aggregated Content Delivery Link Protocol for Radio and Other Audio and Data Services (ACDL). The adapted signals can range from individual audio channels to complex waveforms, potentially including subcarriers within wide basebands. This standard describes building on the Distribution and Communications Protocol (DCP) as a common intermediate layer that can efficiently utilize the services of the ACDL while providing framing for the data carried. In addition, DCP can provide optional services such as Protection, Fragmentation, and Transport (PFT) when such services are useful. Beyond describing the interconnection of DCP and ACDL layers, this standard describes the signal processing required to achieve high quality delivery of the content carried under various conditions of transport data rates and reliability. The result helps to enable optimal utilization of the synchronization, reliability, and security services provided by the ACDL platform for the types of content waveforms covered herein.

P3420
Standard for Aggregated Content Delivery Link Protocol for Radio and Other Audio and Data Services
This standard defines an extensible data transfer protocol intended to carry multiple, often dissimilar, data streams synchronized with one another to support delivery of potentially complex radio program and data content along with associated control information, primarily from studios or other content sources to radio transmitters or other distribution channels, e.g., internally within a “studio” complex, as a Studio-to-Transmitter Link (STL), or for network program distribution. This standard provides the foundation for a suite of documents, the remainder of which define formatting of individual signals and data streams that are to be carried by the protocol described herein. The protocol utilizes Internet Protocol (IP) and various of its supplementary protocols, together with several services that permit synchronization and improve reliability and security of data delivery, as defined in this document. The protocol can include carriage of sampled and digitized analog signals along with a variety of data stream types. The protocol is adaptable to include carriage of any sort of data stream requiring such carriage that can be formatted as a defined Internet Protocol (IP) stream. The protocol does not define the physical layer bearers of the data streams defined herein.
