Abstract
Methods of controlling connection establishment to transmit or receive AA/data in a wireless network are disclosed. A method of controlling connection establishment to transmit or receive AA/data in a first device of a wireless network, which includes a coordinator and at least one device, comprises transmitting connection request information required to request connection establishment with a second device and a connection request message which includes capability information of the first device to the second device, and receiving a connection response message from the second device in response to the connection request message. As well as message formats to said methods are disclosed.
Claims12
A method of controlling connection establishment in order to receive audio/video (A/V) data in a sink device of a wireless network including a coordinator and at least one device, the method comprising:
- transmitting a connection request message to a source device to request a connection;
- and
- receiving a connection response message from the source device in response to the connection request message,
- wherein the connection response message comprises a result of the connection request,
- wherein the connection request message comprises connection request information together with capability information of the sink device,
- wherein the connection request information comprises port information that indicates a sink port via which the A/V data is to be received,
- wherein the capability information comprises a format data field and a format type field,
- wherein the format data field includes format data of the A/V data supportable by the sink device, and
- wherein the format type field includes a type of the format data.
A sink device for controlling connection establishment in order to receive audio/video (A/V) data in a wireless network which includes a coordinator and at least one device, the sink device configured to:
- transmit a connection request message to a source device to request a connection;
- and
- receive a connection response message from the source device in response to the connection request message,
- wherein the connection response message comprises a result of the connection request,
- wherein the connection request message comprises connection request information together with capability information of the sink device,
- wherein the connection request information comprises port information that indicates a sink port via which the A/V data is to be received,
- wherein the capability information comprises a format data field and a format type field,
- wherein the format data field includes format data of the A/V data supportable by the sink device and
- wherein the format type field includes a type of the format data.
