Abstract

A demodulated multimedia signal is generated based on a captured handheld multimedia signal or a captured terrestrial multimedia signal where the handheld multimedia signal is formatted for reproduction on a handheld device and the terrestrial multimedia signal is formatted for reproduction on a computer system. The demodulated multimedia signal or a decoded multimedia signal (based on the demodulated multimedia signal) is transferred to a computer system for visual and/or audible reproduction on a computer system or for transmission to another computer system. The video information associated with the transferred signal is scaled by the computer system prior to display to match the display characteristics and capabilities of the computer system. The transferred signal may correspond to multiple channels of multimedia signals thereby enabling the display of multiple multimedia signals at the same time.
