Abstract

A method of controlling connection establishment to transmit or receive audio/video (A/V) data in a wireless network is provided. The method of controlling connection establishment to transmit or receive A/V data in a first device of a wireless network that includes a coordinator and at least one device includes 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.

Claims

1. A wireless network comprising:

a coordinator configured to broadcast a beacon in the wireless network,

a sink device configured to transmit a connection request message, the connection request message comprising 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 audio/video (A/V) data is to be received, wherein the capability information comprises a format data field and a format type field, and wherein the format data field includes format data of the A/V data supportable by the sink device and the format type field includes a type of the format data; and

a source device configured to receive the connection request message and to transmit a connection response message to the sink device in response to the connection request message, the connection response message comprising a result of the connection request.

2. The wireless network of claim 1, wherein the connection response message further comprises port information of the source device.

3. The wireless network of claim 2, wherein the connection response message further comprises data format information related to the A/V data that can be supported by the source device.

4. The wireless network of claim 3, wherein the connection response message further comprises type information of the data format information.

5. The wireless network of claim 1, wherein the coordinator is further configured to perform a bandwidth reservation procedure for allocating channel resources with the sink device or the source device.

6. The wireless network of claim 5, wherein the source device is further configured to transmit the A/V data by using the channel resources allocated from the coordinator.
