Patent number: 9024995Abstract: A remote camera device is enabled to be used as a source of a video stream in a video call where the local endpoint host in the call, such as a TV, functions as a local endpoint proxy. The TV receives the video stream and transmits it to a remote endpoint host (the other end of the video call) using a conventional video call application. A TV without a camera is able to function as a local endpoint proxy in a video call with a remote device. In another scenario, the TV discovers and connects to a remote camera device. The remote camera, such as a cell phone, streams video to the TV which functions as a local endpoint proxy in the video call. The TV transmits the video to the device at the other end of the call.Type: GrantFiled: August 9, 2012Date of Patent: May 5, 2015Assignee: Samsung Electronics Co., Ltd.Inventors: Fabio Gava, Praveen Kashyap, Shiang-Feng Lee, Fei Xie
