Apparatus and method for managing mmt buffer model using reception quality feedback

A method of managing an MPEG Media Transport (MMT) buffer model using a reception quality feedback (RQF) message in an MMT sending entity, the method comprising:

• transmitting a measurement configuration (MC) message to an MMT receiving entity;
• receiving from the MMT receiving entity the RQF message that includes a maximum transmission delay and a minimum transmission delay;
• calculating a fixed end-to-end transmission delay and a buffer size by using the maximum transmission delay and the minimum transmission delay;
• and
• including the calculated fixed end-to-end transmission delay and buffer size in a buffer control message to transmit the message to the MMT receiving entity.

An apparatus for managing an MPEG Media Transport (MMT) buffer model using a reception quality feedback (RQF) message, the apparatus comprising:

• an MC message receiver configured to receive a measurement configuration (MC) message from an MMT sending entity;
• a delay measuring component configured to measure a maximum transmission delay and a minimum transmission delay in response to a request included in the received MC message;
• a feedback message updater configured to update the RQF message that includes the measured maximum transmission and minimum transmission delay;
• and
• a feedback message transmitter configured to transmit the updated RQF message to the MMT sending entity.
