1. A wireless communication device, comprising:
- circuitry configured to;
establish a wireless connection in a data link layer (L2) with a first device based on designation of a first application;
transmit content data to the first device based on the first application;
designate a second application based on a transmission of a first signal,wherein the first signal includes information for the designation of the second application, andwherein the first signal is transmitted such that the established wireless connection is maintained;
display an image based on the content data;
execute the second application; and
transmit image data, associated with the displayed image, to the first device based on the execution of the second application,wherein the second application is executed while the first application is performed,wherein the first device displays the image based on the image data while the image is displayed at the wireless communication device,wherein the second application corresponds to Wi-Fi certified Miracast and is executed via a direct wireless connection with the first device, andwherein the information is compliant with Wi-Fi Display specification and includes device role information, port information for a protocol associated with the second application and content protection compatibility information.
