DEVICE AND PROCEDURE FOR RETRANSMITTING DIGITAL CHANNELS TRANSMITTED AT SPECIFIC FREQUENCIES WITHIN A SPECTRAL ZONE COMMON TO THE TRANSMISSION OF ANALOGUE CHANNELS

摘要

The present invention concerns a device and method for retransmitting digital channels transmitted at specific frequencies within a spectral zone common to the transmission of analogue channels. The device according to the invention indudes an automatic detection module for digital channels, an automatic search module (311), on the said spectral zone, for a spectral zone free from analogue channels, called free spectral zone, of a size corresponding to that of a group of several digital channels, a frequency grouping (307, 308, 317, 309, 310) and retransmission module of the said group of digital channels in the free spectral zone.
