  • Patent number: 10785362
    Abstract: A method includes receiving, at a first device, an option to receive a video identified by a second device, the option received during a communication session between the first device and the second device. The method includes receiving, at the first device, input indicating acceptance of the offer. The method includes, in response to the input, automatically making a determination, at the first device, whether to have the video sent to a video output device that is distinct from the first device, to receive the video at the first device, or both. The determination is based on a location of the first device. The method also includes, in response to the determination indicating to have the video sent to the video output device, sending a notification to the application server. The notification identifies the video output device.

  • Patent number: 10187509
    Abstract: Devices, systems, and methods are disclosed for sharing video between devices during a voice call. A sending party and a receiving party can view a video during the voice call, enabling a live discussion of the video. During a connected voice call, a first mobile device signals to an application server the desire to share a video with a second mobile device. The application server appropriately instructs a media server to obtain the video and transcode the video for delivery to the second mobile device, the first mobile device, and/or an external display device. The video may be streamed to the media server from the first mobile device or the media server may otherwise locate the video from within the network. The media server streams the video to the second mobile device, the first mobile device, and/or the external display device.

A sending party and a receiving party can view a video during the voice call, enabling a live discussion of the video. During a connected voice call between a first mobile device and a second mobile device, the first mobile device signals to an application server the desire to share a video with the second mobile device. The application server determines the settings and preferences of each device as well as a location of the video. The application server appropriately instructs a media server to obtain the video and transcode the video for delivery to the second mobile device, the first mobile device, and/or an external display device. The external display device is a device at the same location as the second mobile device which may receive the video instead of or in addition to the second mobile device.
