Claim:
1. A method of processing video data, the method comprising: receiving a first aggregation packet according to a real-time transfer protocol (RTP), wherein the first aggregation packet comprises a payload header followed by payload data comprising a first aggregation unit and a second aggregation unit; in response to a transmission mode for the first aggregation packet comprising a multi-session transmission mode, parsing the first aggregation unit, that is the first aggregation unit of the first aggregation packet, to determine a value for a first parameter, wherein the first parameter specifies a decoding order number for a first network abstraction layer (NAL) unit included in the first aggregation unit, wherein the first aggregation unit includes a decoding order number of least significant bits (DONL) field comprising the value for the first parameter; parsing the second aggregation unit to determine a value for a second parameter, wherein the second aggregation unit follows the first aggregation unit in the first aggregation packet, and wherein the second parameter identifies a difference between the decoding order number for the first NAL unit included in the first aggregation unit and a decoding order number for a second NAL unit included in the second aggregation unit, wherein the second aggregation unit includes a decoding order number difference (DOND) field comprising the second value for the second parameter; and based on the first parameter and the second parameter, determining a decoding order for the second NAL unit included in the second aggregation unit.
