Real-time transport protocol header extension for the remaining protocol data unit set size

A computing device comprising:

• one or more memories configured to store a real-time transport protocol (RTP) packet;
• and
• one or more processors coupled to the one or more memories, the one or more processors being configured to:
• determine a protocol data unit (PDU) set, the PDU set comprising a plurality of PDUs, each PDU comprising a corresponding RTP packet;
• determine, for a current RTP packet of the PDU set, a remaining PDU set size, the remaining PDU set size being indicative of a size of a sum of a remainder of the PDUs of the PDU set;
• and
• transmit the current RTP packet, the current RTP packet comprising an RTP header extension comprising a value indicative of the remaining PDU set size, wherein the RTP header extension further comprises a header extension element header having a length of at least one-byte and including an identifier and a length indicator, and wherein the identifier indicates a) that the RTP header extension includes the value indicative of the remaining PDU set size or b) that the RTP header extension includes a value indicative of a PDU set size re-interpreted as the remaining PDU set size.

A computing device comprising:

• one or more memories configured to store a real-time transport protocol (RTP) packet;
• and
• one or more processors coupled to the one or more memories, the one or more processors being configured to:
• receive a current RTP packet, the current RTP packet comprising a protocol data unit (PDU) of a PDU set and comprising an RTP header extension comprising a value indicative of a remaining PDU set size, the remaining PDU set size being indicative of a size of a sum of a remainder of the PDUs of the PDU set, wherein the RTP header extension further comprises a header extension element header having a length of at least one-byte and including an identifier and a length indicator, and wherein the identifier indicates a) that the RTP header extension includes the value indicative of the remaining PDU set size or b) that the RTP header extension includes a value indicative of a PDU set size re-interpreted as the remaining PDU set size;
• and
• allocate resources for the remainder of the PDUs based on the remaining PDU set size.
