decode raw

Hi, all! I want parse and decode raw data from my sdr device. I have RTL2832 based DVB-T receiver. I want get data from receiver via rtl-sdr sotware, parse and decode, and sent completed data through websocket to client in browser. Where I can find description of returning data from rtl_sdr, rtl_tcp. Specs, docs? Or what is the best way to do something like this my idea? Thanks! -- live free or die;
