Abstract
The present invention generally relates to a method and device for handling of audio/video signals originating from a mix of analog and digital sources of audio/video signals. In particular, the present invention relates to optimization of hardware resources and of wiring needed for the interconnection of various analog and digital sources of audio/video signals.
Claims10
A device for reception of digital radio frequency modulated audio/video signals, comprising an analog audio/video input interface for reception of analog non radio frequency modulated audio/video signals, a tuner comprising a front-end for receiving said digital radio frequency modulated audio/video signals and outputting said digital radio frequency modulated audio/video signals on an intermediate frequency, said device further comprising a digital audio/video output interface, an analog-to-digital converter;
- a demodulator and a switch, said switch connecting in a first position said tuner front-end to said analog-to-digital converter, said analog-to-digital converter to said demodulator, and said demodulator to said digital audio/video output interface, for configuring said device to function as a receiver of digital radio frequency modulated audio/video signals, and said switch connecting in a second position said analog audio/video input interface to said analog-to-digital converter and said analog-to-digital converter to said digital audio/video output interface, for configuring said device to function as an analog to digital converter for said analog non radio frequency modulated audio/video signals received on said analog audio/video input interface.
A method for handling of audio/video signals, implemented by a device for reception of digital radio frequency modulated audio/video signals, said device comprising an analog audio/video input interface for reception of analog non radio frequency modulated audio/video signals, a tuner comprising a front-end for receiving of said digital radio frequency modulated audio/video signals and for outputting said digital radio frequency modulated audio/video signals on an intermediate frequency, said device further comprising a digital audio/video output interface, an analog-to-digital converter, a demodulator and a switch, wherein said method comprises the following steps:
- switching said switch to a first position, said switch connecting in said first position said tuner to said analog-to-digital converter, said analog-to-digital convertor to said demodulator, and said demodulator to said digital audio/video output interface, for configuring said device to function as a receiver of digital radio frequency modulated audio/video signals;
- switching said switch to a second position, said switch connecting in said second position said analog audio/video input interface to said analog-to-digital converter and said analog-to-digital convertor to said digital audio/video output interface, for configuring said device to function as an analog to digital converter for said analog non radio frequency modulated audio/video signals received on said analog audio/video input interface.
