Abstract

This document describes techniques (300, 400) and apparatuses (100, 500, 600, 700) for in-band peripheral authentication. These techniques (300, 400) and apparatuses (100, 500, 600, 700) may communicate via a non-media channel allowing host device (102) to authenticate peripheral (106), enable an enhanced operational mode of the host device (102), and/or provide content configured for the peripheral (106) without the use of out-of-band signaling.

Claims

1. A method for authenticating a peripheral device, comprising:

detecting, at a host device, a peripheral device connected to a media interface of the host device, wherein the media interface includes a media channel and a non-media channel;

authenticating the peripheral device to the host device using the non-media channel; and

in response to authenticating the peripheral device to the host device, enabling a full operational mode between the host device and the media interface, wherein the full operational mode includes;

configuring the media interface to provide media content to the peripheral device via the media channel and to receive input from the peripheral device via the non-media channel; and

transmitting control signals to the peripheral device via the non-media channel based on input received from the peripheral device via the non-media channel.

2. The method of claim 1, wherein authenticating the peripheral device to the host device comprises receiving, at the host device, an authentication response from the peripheral device via the non-media channel, and wherein configuring the media content provided to the peripheral device is based on the authentication response.

3. The method of claim 2, wherein the authentication response includes an indication of a device type associated with the peripheral device.

4. The method of claim 3, further comprising:

causing second media content to be presented on the host device;

receiving an input from the peripheral device via the non-media channel; and

controlling presentation of the second media content on the host device using the input received from the peripheral device via the non-media channel.

5. The method of claim 1, further comprising:

determining that the peripheral device has not been authenticated to the host device; and

in response to determining that the peripheral device has not been authenticated to the host device, configuring a limited operational mode associated with the host device and the media interface.

6. The method of claim 5, wherein configuring the limited operational mode comprises disabling one or more interactive features associated with the media content provided to the peripheral device.

7. A system for authenticating a peripheral device, the system comprising:

a hardware processor that is programmed to;

detect, at a host device, a peripheral device connected to a media interface of the host device, wherein the media interface includes a media channel and a non-media channel;

authenticate the peripheral device to the host device using the non-media channel; and

in response to authenticating the peripheral device to the host device, enable a full operational mode between the host device and the media interface, wherein the full operational mode includes causing the hardware processor to;

configure the media interface to provide media content to the peripheral device via the media channel and to receive input from the peripheral device via the non-media channel; and

transmit control signals to the peripheral device via the non-media channel based on input received from the peripheral device via the non-media channel.

8. The system of claim 7, wherein authenticating the peripheral device to the host device comprises receiving, at the host device, an authentication response from the peripheral device via the non-media channel, and wherein configuring the media content provided to the peripheral device is based on the authentication response.

9. The system of claim 8, wherein the authentication response includes an indication of a device type associated with the peripheral device.

10. The system of claim 9, wherein the hardware processor is further programmed to:

cause second media content to be presented on the host device;

receive an input from the peripheral device via the non-media channel; and

control presentation of the second media content on the host device using the input received from the peripheral device via the non-media channel.

11. The system of claim 7, wherein the hardware processor is further programmed to:

determine that the peripheral device has not been authenticated to the host device; and

in response to determining that the peripheral device has not been authenticated to the host device, configure a limited operational mode associated with the host device and the media interface.

12. The system of claim 11, wherein configuring the limited operational mode comprises disabling one or more interactive features associated with the media content provided to the peripheral device.

13. A non-transitory computer-readable medium containing computer-executable instructions that, when executed by a processor, cause the processor to perform a method for authenticating a peripheral device, the method comprising:

detecting, at a host device, a peripheral device connected to a media interface of the host device, wherein the media interface includes a media channel and a non-media channel;

authenticating the peripheral device to the host device using the non-media channel; and

in response to authenticating the peripheral device to the host device, enabling a full operational mode between the host device and the media interface, wherein the full operational mode includes;

configuring the media interface to provide media content to the peripheral device via the media channel and to receive input from the peripheral device via the non-media channel; and

transmitting control signals to the peripheral device via the non-media channel based on input received from the peripheral device via the non-media channel.

14. The non-transitory computer-readable medium of claim 13, wherein authenticating the peripheral device to the host device comprises receiving, at the host device, an authentication response from the peripheral device via the non-media channel, and wherein configuring the media content provided to the peripheral device is based on the authentication response.

15. The non-transitory computer-readable medium of claim 14, wherein the authentication response includes an indication of a device type associated with the peripheral device.

16. The non-transitory computer-readable medium of claim 15, wherein the method further comprises:

causing second media content to be presented on the host device;

receiving an input from the peripheral device via the non-media channel; and

controlling presentation of the second media content on the host device using the input received from the peripheral device via the non-media channel.

17. The non-transitory computer-readable medium of claim 13, wherein the method further comprises:

determining that the peripheral device has not been authenticated to the host device; and

in response to determining that the peripheral device has not been authenticated to the host device, configuring a limited operational mode associated with the host device and the media interface.

18. The non-transitory computer-readable medium of claim 17, wherein configuring the limited operational mode comprises disabling one or more interactive features associated with the media content provided to the peripheral device.
