System for transmitting audio and/or video data and method for granting secured access
A system for transmitting audio and/or video data is described that comprises a functional unit configured to process the audio and/or video data and an error detection unit configured to detect an error in audio and/or video data processing. The system is configured to generate and transmit an access token configured to grant access at least to the functional unit when an error is detected. Further, a method for granting secured access is described.
1. A system for transmitting audio and/or video data comprising:
a functional circuit configured to process audio and/or video data and an error detection circuit configured to detect an error in audio and/or video data processing, the system being configured to generate and transmit an access token to a user, wherein the access token is configured to grant access at least partly to the functional circuit when an error is detected, wherein the access token generated is configured to grant access at least to the portion of the functional circuit which causes the error, wherein the user is enabled to adapt settings of the functional circuit while having access to the functional circuit, and wherein the access is only granted for fixing the occurring error within the functional circuit ensuring that inadvertent access is prohibited.
2. The system according to claim 1 , wherein the error detection circuit is configured to output at least one alarm notification when an error is detected.
3. The system according to claim 2 , wherein the alarm notification is outputted prior to transmitting the access token.
4. The system according to claim 1 , wherein the system comprises a web-enabled end device configured to receive the access token generated.
5. The system according to claim 1 , wherein a cloud circuit is provided that is configured to send the access token.
6. The system according to claim 1 , wherein the system comprises a configuration device that is configured to access the functional circuit at least partly when the access token generated is entered.
7. The system according to claim 1 , wherein the access token generated is configured to only grant access to the portion of the functional circuit which causes the error.
8. The system according to claim 1 , wherein the access token generated is configured to grant access to the functional circuit according to a predetermined setting.
9. The system according to claim 8 , wherein the access token generated is configured to grant at least one of full, partial, and restricted access.
10. The system according to claim 1 , wherein the access token generated is configured to grant access for a predefined time interval.
11. The system according to claim 10 , wherein the time interval is configurable.
12. The system according to claim 1 , wherein the access token generated is configured to become invalid when the error detection circuit outputs a notification indicating normal operation of the system.
13. A method for granting secured access to a functional circuit of a system for processing audio and/or video data, with the following steps:
detecting an error in the processing of the audio and/or video data; and
generating and transmitting an access token to a user, the access token granting access to the functional circuit at least partly when an error is detected, wherein the access token generated is configured to grant access at least to the portion of the functional circuit which causes the error, wherein the user is enabled to adapt settings of the functional circuit while having access to the functional circuit in order to solve the problem, and wherein the access is only granted for fixing the occurring error within the functional circuit ensuring that inadvertent access is prohibited.
14. The method according to claim 13 , wherein an alarm notification is outputted when the error is detected.
15. The method according to claim 14 , wherein the alarm notification is outputted prior to transmitting the access token.
16. The method according to claim 13 , wherein the access token grants access in a predetermined manner.
17. The method according to claim 16 , wherein the access token grants full access, partial access, restricted access and/or access to the portion of the functional circuit causing the error.
18. The method according to claim 13 , wherein the access token generated is only valid for a predefined time interval.
19. The method according to claim 13 , wherein the access token generated becomes invalid once a notification is outputted indicating normal operation of the system.
20. The method according to claim 13 , wherein the access token is used on a configuration device enabling access to the functional circuit at least partly when a valid access token is entered.
