In-band peripheral authentication
First Claim

1. A method, comprising:
- determining an address of a non-media channel at which a peripheral can be authenticated by a host device;
performing an authentication protocol using the address at which the peripheral can be authenticated;
responsive to the peripheral being authenticated, enabling a full operational mode between the host device and a media interface, wherein the full operational mode includes;
causing first content that includes a user interface to be presented on the host device and causing second content to be presented by the peripheral via a media channel of the media interface, wherein the user interface receives user inputs from a user of the host device for interacting with the second content presented by the peripheral; and
transmitting control signals to the peripheral via the non-media channel of the media interface based on the user inputs received by the user interface; and
responsive to the peripheral not being authenticated, enabling a limited operational mode between the host device and the media interface, wherein the limited operational mode includes limiting the quality of media provided via the media channel of the media interface.

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.

10. A method, comprising:
-
making available an address of a non-media channel to a host device for authentication of a peripheral; receiving an authentication request from the host device at the address of the non-media channel; communicating an authentication response to the host device via the non-media channel; receiving, via a media interface of the host device, content configured for the peripheral based on the authentication response communicated to the host device, wherein the received content is of limited media quality if the peripheral is not authenticated; and causing the content configured for the peripheral to be presented by the peripheral via a media channel of the media interface, wherein the content is different than a user interface presented on the host device that receives user inputs from a user of the host device for interacting with the content presented by the peripheral if the peripheral is authenticated; and receiving control signals via the non-media channel based on the user inputs received by the user interface if the peripheral is authenticated. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A peripheral comprising:
-
an authentication module configured to communicate a response to an authentication request received from a host device via a non-media channel; a communication switch configured to, responsive to connection to the host device, switch the non-media channel from a media interface module of the peripheral to the authentication module of the peripheral to enable authentication of the peripheral; and a processor that, responsive to the peripheral being authenticated; causes content configured for the peripheral to be presented via a media channel of the media interface, wherein the content is different than a user interface presented on the host device that receives user inputs from a user of the host device for interacting with the content presented by the peripheral; and receives control signals via the non-media channel based on the user inputs received by the user interface. - View Dependent Claims (20)

19. A peripheral comprising:
-
an authentication module configured to communicate a response to an authentication request received from a host device via a non-media channel; a communication switch configured to, responsive to connection to the host device, switch the non-media channel from a media interface module of the peripheral to the authentication module of the peripheral to enable authentication of the peripheral; and a processor that, responsive to the peripheral being authenticated, causes content configured for the peripheral to be presented via a media channel of the media interface, wherein the content is different than content presented on the host device; and a cable coupled to the peripheral, wherein the communication switch is located within the cable.
