The following paragraphs describe each of the call-outs, (1) through (13), in Figure 8.1. Items (1) through (5) are further detailed in the FEC Encoding Process Section 8.5.1 below. 1) The multiple paths represent the RTP/UDP/IP Streams that are generated for each PLP as described in Sections 8.2, 8.3, and 8.3.4. These are referred to as the Tunneled Packet Streams. 2) The PLP Mux is configured to accept packets from multiple RTP/UDP/IP multicast Streams to be tunneled. 3) The Tunneled Packets are grouped into fixed-size payloads to accommodate the SMPTE ST 2022-1 FEC process [8]. The STLTP RTP fields are defined to allow the Tunneled Packet Streams to be easily recovered and forwarded (refer to Section 8.6 below). The fixed packet size of the ST 2022-1 packets is not defined by this standard and is assumed to be configurable. It is expected that the packet size is within the typical 1500 MTU byte range limit. Note that the larger the packets the longer the latency when performing FEC Transmitter 1 Transmitter 2 Transmitter 3 ATSC A/324:2018 Scheduler / Studio to Transmitter Link 5 January 2018 payloads for easy reconstruction on the Data Consumer side. All other aspects of ST 2022-1 remain identical to the capabilities described in [8] including support for any FEC constraints detailed in Section 8 of that standard. Note that latency will be longer with larger packet lengths. 8.5 STL Transmission Protocol Design Figure 8.1 provides a detailed diagram of the portion of the broadcast Physical Layer chain described by this section.
