Abstract

A method may include obtaining a manifest file that includes various software definitions for various peripheral device functions. The method may further include determining whether the manifest file is signed by a predetermined cryptographic key. The method may further include obtaining, in response to determining that the manifest file is signed by the predetermined cryptographic key, a selection of a peripheral device function among the peripheral device functions in the manifest file. The method may further include performing the peripheral device function using a peripheral device in response to obtaining the selection of the peripheral device function.

First claim

What is claimed is:

1 . A method, comprising:
obtaining, by a computer processor, a first manifest file comprising a plurality of software definitions for a plurality of peripheral device functions; determining, by the computer processor, whether the first manifest file is signed by a predetermined cryptographic key; obtaining, by the computer processor and in response to determining that the first manifest file is signed by the predetermined cryptographic key, a selection of a first peripheral device function among the plurality of peripheral device functions in the first manifest file; and performing, by the computer processor, the first peripheral device function using a first peripheral device in response to obtaining the selection of the first peripheral device function.

2 . The method of claim 1 , further comprising:
obtaining, by a teleconference manager, a subscription of a first event among a plurality of events that are defined within the first manifest file; and presenting an event notification in an application that is provided by the teleconference manager, wherein the event notification is presented in response to the first peripheral device triggering the first event.

3 . The method of claim 1 , further comprising:
generating a graphical user interface (GUI) for a teleconference manager in response to obtaining the selection of the first peripheral device function, wherein the GUI is generated based on a plurality of parameters that are included in the first peripheral device function.

4 . The method of claim 1 , further comprising:
obtaining a predetermined list for a plurality of peripheral devices; obtaining a second manifest file for a second peripheral device among the plurality of peripheral devices; determining whether the second peripheral device is associated with the predetermined list; and disabling, in response to determining that the second peripheral device is not associated with the predetermined list, a second peripheral device function corresponding to the second manifest file.

5 . The method of claim 1 , further comprising:
obtaining a second manifest file for a second peripheral device; and performing a validation process on the second manifest file based on a predetermined criterion, wherein performing the validation process comprises generating a first digital signature using a private cryptographic key.

6 . The method of claim 5 , further comprising:
obtaining the second manifest file; determining whether the second manifest file is signed by the first digital signature; and performing a second peripheral device function using a second peripheral device in response to determining that the second manifest file is signed by the private cryptographic key.

7 . The method of claim 1 , further comprising:
presenting a graphical user interface (GUI) on a display device, wherein the GUI comprises a plurality of GUI objects; obtaining, from a user device, a selection of a first GUI object within the GUI, wherein the first GUI object is associated with the first peripheral device; selecting the first manifest file among a plurality of manifest files based on the selection of the first GUI object; and presenting, within the GUI, a plurality of peripheral device functions based on the first manifest file.

8 . The method of claim 1 ,
wherein the first peripheral device is a camera device, and wherein the first peripheral device function is an autozoom function.

9 . The method of claim 1 ,
wherein the first peripheral device comprises a microphone device, and wherein the first peripheral device function identifies, within a graphical user interface (GUI), a speaker among a plurality of speakers that is providing an audio input to the microphone device.

10 . The method of claim 1 ,
wherein the first manifest file is a JavaScript Object Notation (JSON) file.

11 . A non-transitory computer readable medium storing instructions executable by a computer processor, the instructions being configured to perform a method comprising:
obtaining a manifest file comprising a plurality of software definitions for a plurality of peripheral device functions; determining whether the manifest file is signed by a predetermined cryptographic key; obtaining, in response to determining that the manifest file is signed by the predetermined cryptographic key, a selection of a peripheral device function among the plurality of peripheral device functions in the manifest file; and performing the peripheral device function using a peripheral device in response to obtaining the selection of the peripheral device function.

12 . A system, comprising:
a peripheral device; a teleconference manager coupled to the peripheral device, wherein the teleconference manager is configured to perform a method comprising:
obtaining a manifest file comprising a plurality of software definitions for a plurality of peripheral device functions;
determining whether the manifest file is signed by a predetermined cryptographic key;
obtaining, in response to determining that the manifest file is signed by the predetermined cryptographic key, a selection of a peripheral device function among the plurality of peripheral device functions in the manifest file; and
performing the peripheral device function using the peripheral device in response to obtaining the selection of the peripheral device function.
