System and method for television signal demodulation and decoding

A modem for use with a computer having a demodulator, said modem comprising:

• a hardware interface;
• a digital-to-analog converter configured to receive an analog television signal and generate a digital television signal;
• and
• a smart direct memory access controller;
• wherein said modem is configured to provide said digital television signal to said computer over said hardware interface;
• wherein said modem is further configured to receive a demodulated signal from said demodulator over said hardware interface, said demodulated signal being a demodulation of said digital television signal;
• wherein said smart direct memory access controller is configured to deinterleave data in said demodulated signal to generate deinterleaved demodulated data;
• and
• wherein said modem is configured to provide said deinterleaved demodulated signal to said computer over said hardware interface.

A method for use by a modem for communication with a computer, said method comprising:

• receiving a digital television signal;
• demodulating said digital television signal, using a demodulator front-end, to generate a demodulated front-end signal;
• storing said demodulated front-end signal in time domain using a time domain memory;
• applying fast Fourier transform (FFT) to said demodulated front-end signal;
• storing said demodulated front-end signal in frequency domain using a frequency domain memory;
• transmitting said demodulated front-end signal in time domain and frequency domain to said computer over a hardware interface.

A method for use by a modern for communication with a computer having a demodulator, said method comprising:

• converting an analog television signal to a digital television signal;
• providing said digital television signal to said computer over a hardware interface;
• receiving a demodulated signal from said demodulator over said hardware interface, said demodulated signal being a demodulation of said digital television signal;
• deinterleaving data in said demodulated signal to generate a deinterleaved demodulated signal;
• and
• providing said deinterleaved demodulated signal to said computer over said hardware interface.
