  • Patent number: 12170702
    Abstract: A method, apparatus, and computer program product are disclosed for modifying the transmission of media content update packets based on a determination that the elapsed uplink time and remaining downlink time in the aggregate are within a satisfactory round-trip delay time. In this regard, the method, apparatus, and computer program product are configured to correlate a returned media content update packet with an associated device update packet or packets. Correlating media content update packets with an associated device update packet may require identifying a returned packet containing a media content update by analyzing packets containing video streams to identify packets comprising reference video frames. Identifying reference video frame packets may assist in identifying the associated uplink packet or packets containing device pose and position or other user input.
