Abstract
A method of performing communication between a first device and a second device by using a Wi-Fi direct scheme is provided. The method may include receiving, by the first device, information on relating to a content protection capability of the second device in during a device discovery procedure; and determining, by the first device, whether to perform a connection setup procedure with the second device based on the received information on relating to the content protection capability of the second device.
Claims17
A method of performing communication between a first device and a second device by using a peer to peer (P2P) scheme, the method comprising:
- transmitting, by the first device, a probe request message, for a device discovery procedure;
- receiving, by the first device, a probe response message comprising content protection capability information of the second device in response to the probe request message;
- performing a connection setup procedure with the second device based on the probe response message comprising the content protection capability information of the second device;
- and
- performing a capability negotiation procedure with the second device by receiving the content protection capability information of the second device, after the connection setup procedure,
- wherein the probe request message comprises content protection capability information of the first device and information relating to a device type of the first device, and the information relating to the device type of the first device indicates whether a role of a source device or a role of a sink device is supported.
A first device for performing communication using a peer to peer (P2P) scheme with a second device, the first device comprising:
- a transmitter configured to transmit a probe request message, for a device discovery procedure;
- a receiver configured to receive a probe response message comprising content protection capability information of the second device in response to the probe request message;
- and
- a processor configured to perform a connection setup procedure with the second device based on the probe response message comprising the content protection capability information of the second device, and perform a capability negotiation procedure with the second device,
- wherein the probe request message comprises a content protection capability information of the first device and information relating to a device type of the first device, and the information relating to the device type of the first device indicates whether a role of a source device or a role of a sink device is supported,
- wherein the receiver is further configured to receive the content protection capability information of the second device in the capability negotiation procedure, after the connection setup procedure.
