Embodiments are disclosed for a device for determining a presentation time for a generated packet. An example device includes a communication interface communicatively connectable to another device and configured to transmit data, a processor, and a storage device that stores instructions executable by the processor to receive a stream packet, extract a timestamp from the stream packet, and add one or more offsets to the extracted timestamp to determine a presentation time. The instructions are further executable to transmit a generated packet, the generated packet including an indication of the determined presentation time.
