You can receive HDTV signals in your home through any of the three broadcast systems, over the air through antenna, cable, and satellite.
Although some hurdles regarding digital broadcasting remain unaddressed, they would be addressed soon.
For digital broadcasting, a show is first recorded in HD format using HD cameras and equipments. Then, it is distributed digitally over the air, cable or satellite.
Now, you just need an HDTV-compatible TV with a HDTV tuner or receiver to decode the digital signal. That is it. Your HDTV is ready. Sit back and enjoy.
