Abstract (en)
[origin: WO2004062290A1] The invention relates to a device (10) for the digital radio transmission of data comprising video information. The inventive device is characterised in that it comprises: a video acquisition camera (11); a compression stage (15) which can generate a digital signal from the signal originating from the video acquisition camera (11), with a compression ratio which is at least greater than 1:300; a conforming stage (16) which can insert the compressed video signal into a frame (18); a digital modulation stage (24) which can generate a digital radio signal; a transmission/reception stage (20, 22) which can transmit the digital radio signal in a pre-determined frequency band to analogue transmission devices and which can receive signals comprising frames with the same structure transmitted by said analogue devices.
