Abstract

Systems and methods for adjusting the relative timing of audio and video signals of a video game responsive to a lag differential between an audio system and a video system connected to a game platform are described. In one embodiment, a method includes determining, by a game platform, a difference between an audio lag of an audio system connected to the game platform and a video lag of a video system connected to the game platform. The game platform may then transmit an audio signal and a video signal, wherein the relative timing of the audio signal to the video signal is reflective of the determined difference. The difference between the audio lag and video lag may be measured directly, or the audio and video lag may each be measured separately.

Claims

1. A method for adjusting the relative transmission times of audio and video signals of a video game, the method comprising:

a. determining, by a game platform, a difference between an audio lag of an audio system connected to the game platform and a video lag of a video system connected to the game platform; and

b. transmitting, by the game platform, an audio signal and a video signal, wherein the relative timing of the audio signal to the video signal is reflective of the determined difference.

2. The method of claim 1, wherein step (a) comprises displaying a first input screen which accepts input corresponding to a difference between an audio lag of an audio system connected to the platform and a video lag of a video system connected to the platform.

3. The method of claim 2, wherein the first input screen receives input from a user specifying a temporal relationship between a displayed image and a played sound.

4. The method of claim 2, wherein step (a) further comprises displaying a second input screen which directs a user to perform an action synchronously with at least one of a video and audio cue.

5. The method of claim 2, wherein step (a) further comprises displaying a second input screen which directs a user to perform an action synchronously with an audio cue.

6. The method of claim 1, wherein step (a) comprises:

displaying a first input screen which directs a user to perform an action synchronously with an audio cue, and displaying a second input screen which directs a user to perform an action synchronously with a video cue.

7. The method of claim 1, wherein step (a) comprises:

a. outputting at least one test signal; and

b. receiving a response from a sensor indicating detection of the test signal.

8. The method of claim 7, wherein the sensor is connected to a simulated musical instrument.

9. The method of claim 1, wherein step (a) comprises determining, by a game platform, an average difference between an audio lag of an audio system connected to the platform and a video lag of a video system connected to the platform.

10. The method of claim 1, wherein the video signal comprises video of a rhythm-action game, and the audio signal comprises music of the rhythm-action game.

11. A computer readable medium having executable instructions for method for adjusting the relative transmission times of audio and video signals of a video game, the computer readable medium comprising:

executable instructions for determining, by a game platform, a difference between an audio lag of an audio system connected to the platform and a video lag of a video system connected to the platform; and

executable instructions for transmitting, by the game platform, an audio signal and a video signal, wherein the relative timing of the audio signal to the video signal is reflective of the determined difference.

12. The computer readable medium of claim 11 comprising executable instructions for displaying a first input screen which accepts input from a user specifying a difference between an audio lag of an audio system connected to the platform and a video lag of a video system connected to the platform.

13. The computer readable medium of claim 12, wherein the first input screen directs a user to specify a temporal relationship between a displayed image and a played sound.

14. The computer readable medium of claim 12, comprising executable instructions for displaying a second input screen which directs a user to perform an action synchronously with at least one of a video and audio cue.

15. The computer readable medium of claim 11 comprising executable instructions for displaying a first input screen which directs a user to perform an action synchronously with an audio cue, and displaying a second input screen which directs a user to perform an action synchronously with a video cue.

16. The computer readable medium of claim 11 comprising executable instructions for receiving input from an lag calibration device.

17. The computer readable medium of claim 11 comprising executable instructions for determining an average difference between an audio lag of an audio system connected to the platform and a video lag of a video system connected to the platform.

18. The computer readable medium of claim 11, wherein the video signal comprises video of a rhythm-action game, and the audio signal comprises music of the rhythm-action game.

19. A computer readable medium having executable instructions for calibrating the timing of transmission of audio and video signals of a video game, the computer readable medium comprising:

executable instructions for measuring, by a game platform, an audio lag of an audio system connected to the game platform;

executable instructions for measuring, by the game platform, a video lag of a video system connected to the game platform; and

executable instructions for transmitting, by the game platform, an audio signal and a video signal, wherein the timing of the audio signal is reflective of the measured audio lag, and the timing of the video signal is reflective of the measured video lag.

20. The computer readable medium of claim 19, wherein the video lag is measured independently of the audio lag.
