Abstract

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