Abstract

Video signals for a mobile terminal are converted to accommodate reproduction by an alternative display terminal. The video signal is processed to provide a converted video signal appropriate for an alternative display terminal that is separate from the mobile terminal. This converted video signal is then provided for the alternative display terminal to accommodate the corresponding video display on a screen provided by the alternative (e.g., external) display terminal.
