7.1. Single NAL Unit and Non-Interleaved Mode

The receiver includes a receiver buffer to compensate for transmission delay jitter. The receiver stores incoming packets in reception order into the receiver buffer. Packets are de-packetized in RTP sequence number order. If a de-packetized packet is a single NAL unit packet, the NAL unit contained in the packet is passed directly to the decoder. If a de-packetized packet is an STAP-A, the NAL units contained in the packet are passed to the decoder in the order in which they are encapsulated in the packet. For all the FU-A packets containing fragments of a single NAL unit, the de-packetized fragments are concatenated in their sending order to recover the NAL unit, which is then passed to the decoder.

Informative note: If the decoder supports arbitrary slice order, coded slices of a picture can be passed to the decoder in any order, regardless of their reception and transmission order.
