Abstract
In aspects of fast television channel change initiated from a second screen device, a mobile device implemented as the second screen device can receive a navigation input in a viewport displayed on an integrated display of the mobile device. Video selection options for video content are displayed in the viewport on the integrated display of the mobile device responsive to the navigation input. A content display application on the mobile device can determine video identifiers of the video content for each of the video selection options displayed in the viewport, where each video identifier uniquely identifies a respective video content. The mobile device can then communicate the video identifiers to a first screen device, such as a television display device, that initiates a request to a video content server for initial video data corresponding to each of the video content based on the video identifiers received from the mobile device.
