Audio synchronization for two dimensional and three dimensional video signals

摘要

A method for processing audio/video signals. The method includes determining if the video signals are in two dimensional or three dimensional format. If the video signals are in two dimensional format, the method includes providing a first delay to be applied to the audio signals. If the video signals are in three dimensional format, the method includes providing a second delay, longer than the first delay, to be applied to the audio signals.

1. A method for processing input audio/video signals, for use with a television and a separate audio system comprising a plurality of acoustic drivers, the method comprising:
automatically examining video signal metadata provided in the input video signal and determining if the video signals are in standard definition or high definition format; automatically examining video signal metadata provided in the input video signal and determining if the video signals are in two dimensional or three dimensional format; if the input video signals are in two dimensional format, providing a first range of time delays to be applied to the audio signals, where the first range of time delays is bounded by a first minimum delay and a first maximum delay, and is broken up into a first series of audio delay steps, where each step represents a fraction of the first range of time delays; if the input video signals are in three dimensional format, providing a second range of time delays to be applied to the audio signals, where the second range of time delays is bounded by a second minimum delay and a second maximum delay, and is broken up into a second series of audio delay steps, where each step represents a fraction of the second range of time delays; wherein the second minimum delay is longer than the first minimum delay; wherein the second maximum delay is longer than the first maximum delay; displaying the number of audio delay steps which when selected, represent the audio signal time delay; providing a manually operable control to allow for user selection of the number of delay steps: after the user selects a number of delay steps, determining an audio signal delay based on the selected number of steps; and applying the determined delay to the input audio signals and then applying the delayed audio signals to the plurality of acoustic drivers. to create the audio output from the input audio/visual signals.
