Abstract: In aspects of reverse casting from a first screen device to a second screen device, a mobile device implemented as the second screen device can determine that it is proximate in location to the first screen device, such as a television device, based on both the mobile device and the television device being connected to a local network. The mobile device and the television device can be automatically associated to enable data being synchronized between the two devices based on determining that the devices are proximate in location. The television device displays video content prior to the two devices being associated. The mobile device can then receive contextual information that corresponds to the video content being displayed on the television device. The contextual information can be determined by an automated analysis of the video content at a video content service as the video content is distributed to the television device.
