1. A method for communication, comprising:
transmitting, at a first device to a second device, a first initial duration of a first presentation time offset, the first presentation time offset being a period from data being input to the first device to the data being output from the second device;
receiving, from the second device, a second initial duration of a second presentation time offset, the second presentation time offset being a period from data being input to the second device to the data being output from the first device;
determining which of the first initial duration and the second initial duration is longer; and
determining an adjusted duration of the first presentation time offset based on the determination of which of the first initial duration and the second initial duration is longer;
wherein the first presentation time offset and the second presentation time offset comprise an end-to-end delay between the first device and the second device and a data buffering time.
