TV Coaxial input to digital interface

Hi ,

I am working on a Hobby project ,

I need to convert the coaxial input of a Cable TV interface into digital signals and provide to a processor ,

Can anyone help me out with how to proceed with the project ?

Any links regarding the same will be of great help , Thank you .

for this u need a modem

good luck, each cable company is a little different. Basically u need some sort of RF tuner front end and a demodulator, probably a QAM demodulator. Then a boat load of digital crunching to get out audio and video
