Claim:
1. A method of processing video data, the method comprising: receiving a first fragmentation unit (FU) comprising a subset of a first fragmented network abstraction layer (NAL) unit; parsing a start bit of the first FU to determine if the first FU comprises a start of the first fragmented NAL unit; determining that the first FU comprises the start of the first fragmented NAL unit and a transmission mode for the first FU is a multi-session transmission mode using more than one real-time transport protocol (RTP) session; in response to determining that the first FU comprises the start of the first fragmented NAL unit and the transmission mode for the first FU is the multi-session transmission mode, determining that a decoding order number of least significant bits (DONL) field is present in the first FU, wherein the DONL field being present in the first FU is based on the first FU comprising the start of the first fragmented NAL unit and the transmission mode for the first FU being the multi-session transmission mode; parsing the DONL field to determine a decoding order number for the first fragmented NAL unit, wherein a value of the decoding order number is equal to a value in the DONL field; and decoding the first fragmented NAL unit based on the determined decoding order.
