Nvidia patents method to keep cloud video and audio in sync

Nvidia describes a system that embeds audio data directly into the header of video frames before sending them over a network. By attaching the sound to the specific video image it belongs to, the system ensures that audio and video stay synchronized even if network delays or packet loss occur during cloud processing.

Why it mattersThis technique could help improve the reliability of cloud-based gaming and video streaming services by preventing the common issue of sound and picture drifting out of alignment.

In the filing’s own words

Systems and methods for implementing media synchronization for cloud processing are disclosed. A system can encode a plurality of video frames to generate a plurality of encoded frames, where the video frames are associated with corresponding audio. The system can update a respective header of at least one of the plurality of encoded frames to include encoded audio generated from the corresponding audio. The system can transmit one or more network packets including the plurality of encoded frames as part of a video stream. This approach ensures that audio and video data remain synchronized by embedding the audio data within the video frames, thereby reducing the likelihood of desynchronization due to network latency or packet loss.

What exactly they claim (claim 1)

1. One or more processors comprising: one or more circuits to: encode a plurality of video frames to generate a plurality of encoded frames, the plurality of video frames associated with corresponding audio; update a respective header of at least one of the plurality of encoded frames to include encoded audio generated from the corresponding audio; and transmit one or more network packets including the plurality of encoded frames as part of a video stream.
