Sound control circuit for a digital audiovisual reproduction system
View Patent ↗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.
1. A sound control circuit connected to an amplifier-tuner and configured to support a plurality of input sources, installed on an audiovisual reproduction system managed by an operating system,
wherein the operating system is configured to automatically send an order on an address bus of the sound control circuit to enable an electric circuit, in order to switch an amplifier of the audiovisual reproduction system off during a period in which the audiovisual reproduction system is initialized, and to send an order to disable the electric circuit after the initialization has finished to switch the amplifier on only after initialization has finished.
2. The sound control circuit of claim 1 , wherein one input port to the sound control circuit is connected to an integrated circuit comprising a non-volatile memory that the operating system uses through the sound control circuit to read or store information in the integrated circuit memory.
3. The sound control circuit according to claim 2 , wherein the information stored in the integrated circuit memory is only accessible after the user has been authenticated by entering a code.
4. 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.
5. A sound control circuit according to claim 4 , 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.
6. The sound control circuit according to claim 1 , further comprising a game port 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.
7. The sound control circuit according to claim 1 , further comprising a game port installed on the digital audiovisual reproduction 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.
8. A sound control circuit according to claim 7 , 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.
9. A sound control circuit according to claim 8 , wherein a second pin on the game port is grounded through a second switch to increase volume.
10. A sound control circuit according to claim 9 , wherein a third pin on the game port is grounded through a third switch to reduce the volume.
11. A sound control circuit according to claim 10 , 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.
12. A sound control circuit according to claim 7 , wherein a 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.
13. A sound control circuit according to claim 7 , wherein a 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.
14. An audiovisual reproduction system managed by an operating system, a sound control circuit being connected to an amplifier-tuner, configured to support a plurality of input sources, and installed on the audiovisual reproduction system,
wherein the operating system is configured to automatically send an order on an address bus of the sound control circuit to enable an electric circuit, in order to switch an amplifier of the audiovisual reproduction system off during a period in which the audiovisual reproduction system is initialized, and to send an order to disable the electric circuit after the initialization has finished to switch the amplifier on only after initialization has finished.
15. The audiovisual reproduction system according to claim 14 , wherein one input port to the sound control circuit is connected to an integrated circuit comprising a non-volatile memory that the operating system uses through the sound control circuit to read or store information in the integrated circuit memory.
16. The audiovisual reproduction system according to claim 15 , wherein the information stored in the integrated circuit memory is only accessible after the user has been authenticated by entering a code.
17. The audiovisual reproduction system according to claim 14 , wherein the sound control circuit constitutes different hardware than does an input control circuit connected to the audiovisual reproduction system.
18. The audiovisual reproduction system according to claim 17 , 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.
19. The audiovisual reproduction system according to claim 14 , further comprising a game port 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.
20. The audiovisual reproduction system according to claim 14 , further comprising a game port installed on the digital audiovisual reproduction 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.
