Method and apparatus for signaling and operation of low delay consumption of media data in MMT

A method for wireless communication with at least one base station comprising:

• receiving a packet comprising a control message with a header and a payload related to fragments of multimedia content, wherein the header comprises:
• a message identifier indicating whether the control message is a low delay consumption message,
• a length of the control message, and
• a version of the control message, and wherein the payload comprises:
• a coding dependency structure flag indicating whether a decoding order of the packet is the same as a presentation order,
• a base presentation time offset indicating a base offset for presenting the fragments of the multimedia content,
• a period between two intra-coded samples,
• a sign of a sample presentation time offset for each fragment, and
• a value of the sample presentation time offset for each fragment;
• and
• determining whether the control message is the low delay consumption message based on the message identifier;
• responsive to the control message being the low delay consumption message, configuring the packet based on the payload and the control message before receiving headers of the fragments of the multimedia content;
• and
• responsive to the coding dependency structure flag indicating that the decoding order of the packet is the same as the presentation order, configuring the packet based on a base presentation time offset.

A system, the system comprising:

• a user equipment for wireless communication with at least one base station, the user equipment comprising:
• a transceiver operable to communicate with the at least one base station by transmitting radio frequency signals to the at least one base station and by receiving radio frequency signals from the at least one base station, the transceiver configured to:
• receive a packet comprising a control message with a header and a payload related to fragments of multimedia content, wherein the header comprises:
• a message identifier indicating whether the control message is a low delay consumption message,
• a length of the control message, and
• a version of the control message, wherein the payload comprises:
• a coding dependency structure flag indicating whether a decoding order of the packet is the same as a presentation order,
• a base presentation time offset indicating a base offset for presenting the fragments of the multimedia content,
• a period between two intra-coded samples,
• a sign of a sample presentation time offset for each fragment, and
• a value of the sample presentation time offset for each fragment;
• and
• processing circuitry configured to:
• determine whether the control message is the low delay consumption message based on the message identifier;
• responsive to the control message being the low delay consumption message, configure the packet based on the payload and the control message before receiving headers of the fragments of the multimedia content;
• and
• responsive to the coding dependency structure flag indicating that the decoding order of the packet is the same as the presentation order, configure the packet based on a base presentation time offset.
