  • Patent number: 10034036
    Abstract: In one example, a client device interacting with a streaming application server may synchronize an audio stream to a corresponding video stream. The client streaming device may have an audio channel to receive a current audio packet of an audio stream from a streaming application server. The client streaming device may have a video channel to receive a current video packet of a video stream from the streaming application server. The client streaming device may execute a media synchronization module to synchronize the audio stream to the video stream by measuring a video display time change for the video stream describing a video delay between generating video data at the streaming application server and displaying the video data at the streaming client device to a user. The client streaming device may execute an audio adjustment module to adjust an audio presentation time for the audio stream indicating when a subsequent audio packet is played to the user based on the video display time change.
