Is there any RF Modulator, which can convert complete Cable frequencies to digital

Hello,
Question: I am looking for a RF modulator, which can convert complete analogue signal (e.g 48 MHz to 848 Mhz) to digital signal directly from cable input but not from HDMI/AV input.

Reason :

Recently I bought a set top box DVB-C, it only finds digital channels but can not find analogue signal. Now I want any modulator which can convert complete frequency band into digital signal so that the all channels frequency be digitised and can be utilised by STB

You would need a separate receiver for each analogue channel and convert it to DVB. This would be a 2 step process, with the output from the receiver being baseband composite video and this being fed into a DVB modulator.

All this equipment exists, but with the move to digital now almost complete across most of Europe, Asia and America, you will probably find it hard to track down the receivers as standalone units and will need to use old VCRs. The DVB modulators are available in blocks of 4 or more, but make sure it has the AV input, not HDMI, or you will need another box to convert from AV composite video to HDMI! This: Conexer DVB-T Modulators - Antiference is the thing I am thinking of.

Not going to be cheap, may £350 per analogue channel.
