Abstract

Sound control circuit comprising a game port, installed on a digital audiovisual reproduction system managed by an operating system, characterized in that the game port in the sound control circuit is used to create an access to the configuration of the audiovisual reproduction system and/or additional management functions for the audiovisual reproduction system.

Claims

1. A sound control circuit connected to an amplifier-tuner and configured to support a plurality of input sources, comprising:

a game port installed on a digital audiovisual reproduction system managed by an operating system,

wherein the game port is part of the sound control circuit, and the game port comprises pin connectors that are connected to electric switches arranged to enable access to configuration of the audiovisual reproduction system, and to manage the audiovisual reproduction system, said electrical switches being part of the digital audiovisual reproduction system.

2. The sound control circuit according to claim 1, wherein a first pin on the game port is grounded through a first switch to provide a temperature alarm function for the audiovisual reproduction system.

3. The sound control circuit according to claim 2, wherein a second pin on the game port is grounded through a second switch to increase volume.

4. The sound control circuit according to claim 3, wherein a third pin on the game port is grounded through a third switch to reduce the volume.

5. The sound control circuit according to claim 4, wherein a fourth pin on the game port is grounded through a fourth switch when a microphone is activated, to increase the microphone volume and reduce the volume of other audio sources that are managed by the audiovisual reproduction system.

6. The sound control circuit according to claim 1, wherein first, second, third and fourth pins on the game port are grounded through a fifth switch for a short period to obtain access to system configuration modification functions.

7. The sound control circuit according to claim 1, wherein first, second, third and fourth pins on the game port are grounded through a fifth switch for a long period to cancel a musical selection being played, and other musical selections that are in a queue of songs to be played residing in a memory of the audiovisual reproduction system.

8. The sound control circuit according to claim 1, wherein the sound control circuit constitutes different hardware than does an input control circuit connected to the audiovisual reproduction system.

9. The sound control circuit according to claim 8, wherein both the sound control circuit and the input control circuit are configured (1) to access the configuration of the audiovisual reproduction system, and (2) to manage the audiovisual reproduction system, via respective peripherals connected to ports thereof.

10. The sound control circuit according to claim 1, wherein the game port is further configured to manage any two or more of:

sound signals provided by microphone input to the audiovisual reproduction system, transmission of sound signals to loudspeakers from the audiovisual reproduction system, and songs stored in a mass storage location of the audiovisual reproduction system.

11. A digital audiovisual reproduction system, comprising:

an operating system configured to manage operations of the digital audiovisual reproduction system;

a sound control circuit configured to support a plurality of input sources for the digital audiovisual reproduction system,

wherein the sound control circuit includes a game port, the game port comprising pin connectors operably connected to electrical switches of the digital audiovisual reproduction system, the sound control circuit providing access to configurational and management-related settings of the digital audiovisual reproduction system through the electrical switches.

12. The system according to claim 11, wherein a first pin on the game port is grounded through a first switch to provide a temperature alarm function for the audiovisual reproduction system.

13. The system according to claim 12, wherein a second pin on the game port is grounded through a second switch to increase volume.

14. The system according to claim 13, wherein a third pin on the game port is grounded through a third switch to reduce the volume.

15. The system according to claim 14, wherein a fourth pin on the game port is grounded through a fourth switch when a microphone is activated, to increase the microphone volume and reduce the volume of other audio sources that are managed by the audiovisual reproduction system.

16. The system according to claim 11, wherein first, second, third and fourth pins on the game port are grounded through a fifth switch for a short period to obtain access to system configuration modification functions.

17. The system according to claim 11, wherein first, second, third and fourth pins on the game port are grounded through a fifth switch for a long period to cancel a musical selection being played, and other musical selections that are in a queue of songs to be played residing in a memory of the audiovisual reproduction system.

18. The system according to claim 11, wherein the sound control circuit constitutes different hardware than does an input control circuit connected to the audiovisual reproduction system.

19. The system according to claim 18, wherein both the sound control circuit and the input control circuit are configured (1) to access the configuration of the audiovisual reproduction system, and (2) to manage the audiovisual reproduction system, via respective peripherals connected to ports thereof.

20. The system according to claim 11, wherein the game port is further configured to manage any two or more of:

sound signals provided by microphone input to the audiovisual reproduction system, transmission of sound signals to loudspeakers from the audiovisual reproduction system, and songs stored in a mass storage location of the audiovisual reproduction system.
