    Abstract: A mobile media device may preemptively switch from a terrestrial video signal of a simulcast to a mobile video signal of the same simulcast upon detecting displacement motion. In one example, an apparatus includes a display configured to display video data, and a signal selection unit configured to determine whether the apparatus is moving, wherein the signal selection unit is configured to cause the display to display video data from a terrestrial signal of a simulcast broadcast when the apparatus does not detect displacement motion, and wherein the signal selection unit is configured to cause the display to display video data from a mobile signal of the simulcast broadcast when the signal selection unit detects displacement motion. In this manner, the apparatus may avoid loss of data from the terrestrial video signal that may be caused while moving.
