Signaling and identifying picture boundary in video payload format over IP network

A device for packetizing a plurality of network abstraction layer (NAL) units of a picture, the device comprising:

• at least one memory configured to store program code;
• and
• at least one processor configured to read the program code and operate as instructed by the program code, the program code including:
• obtaining code configured to cause the at least one processor to obtain the plurality of NAL units including a first NAL unit of the picture and a last NAL unit of the picture;
• splitting code configured to cause the at least one processor to split the first NAL unit of the picture into a first plurality of fragments and splitting the last NAL unit of the picture into a last plurality of fragments;
• packetizing code configured to cause the at least one processor to packetize the first plurality of fragments into a first plurality of fragmentation unit (FU) packets and packetizing the last plurality of fragments in to a last plurality of FU packets;
• and
• transmitting code configured to cause the at least one processor to transmit the first plurality of FU packets and the last plurality of FU packets,
• wherein a last FU packet of the last plurality of FU packets includes a last FU header including a last E bit and a last R bit,
• wherein the last R bit is set to 1, and
• wherein the last R bit being set to 1 indicates that a fragment corresponding to the last FU packet of the last plurality of FU packets is a last fragment of the last NAL unit of the picture.

A non-transitory computer-readable medium storing instructions, the instructions comprising:

• one or more instructions that, when executed by one or more processors of a device for packetizing a plurality of network abstraction layer (NAL) units of a picture, cause the one or more processors to:
• obtain the plurality of NAL units including a first NAL unit of the picture and a last NAL unit of the picture;
• split the first NAL unit of the picture into a first plurality of fragments and splitting the last NAL unit of the picture into a last plurality of fragments;
• packetize the first plurality of fragments into a first plurality of fragmentation unit (FU) packets and packetizing the last plurality of fragments in to a last plurality of FU packets;
• and
• transmit the first plurality of FU packets and the last plurality of FU packets,
• wherein a last FU packet of the last plurality of FU packets includes a last FU header including a last E bit and a last R bit,
• wherein the last R bit is set to 1 and
• wherein the last R bit being set to 1 indicates that a fragment corresponding to the last FU packet of the last plurality of FU packets is a last fragment of the last NAL unit of the picture.
