Some demonstrative embodiments include apparatuses, devices, systems and methods of channel switching. For example, a video source device may include a radio to establish a peer to peer (P2P) connection over a first wireless communication channel between the video source device and a video sink, the P2P connection to stream from the video source device to the video sink content to be displayed on a display device, and to receive from the video sink a message including type information indicating a type of the display device; and a controller to initiate, based on the type of the display device, a channel switch procedure to switch the P2P connection from the first wireless communication channel to a second wireless communication channel.
