MULTIMEDIA PLAYBACK SYNCHRONIZATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240022783 titled 'MULTIMEDIA PLAYBACK SYNCHRONIZATION

Simplified Explanation

The patent application describes a device that can synchronize audio and video output by obtaining output delay data from an audio output device. The device includes processors that determine a synchronization delay based on the output delay data and host delay data. The device then sends audio data to the audio output device and delayed video data to a display.

  • The device obtains output delay data from an audio output device.
  • The processors determine a synchronization delay based on the output delay data and host delay data.
  • The device sends audio data to the audio output device.
  • The device sends delayed video data to a display.

Potential Applications:

  • Audio-visual synchronization in multimedia systems.
  • Gaming consoles to ensure audio and video are in sync.
  • Virtual reality systems to enhance the immersive experience.

Problems Solved:

  • Eliminates audio and video desynchronization issues.
  • Provides a seamless audio-visual experience.
  • Improves user satisfaction in multimedia applications.

Benefits:

  • Enhanced audio-visual synchronization.
  • Improved user experience in multimedia systems.
  • Reduced latency and delay in audio and video playback.


Original Abstract Submitted

a device includes one or more processors configured to obtain output delay data based on a transmission from an audio output device. the output delay data indicates a playback delay associated with audio output by the audio output device. the one or more processors are further configured to determine, based on the output delay data and host delay data, a synchronization delay to coordinate audio output by the audio output device and video output at a display. the one or more processors are further configured to initiate sending of audio data to the audio output device and to send video data to the display. the video data is delayed, based on the synchronization delay, relative to the sending of the audio data.
