Living in Los Angeles, you probably have the ability to receive OTA (off the air) signals, assuming you have a 'clear sight' (unobstructed) shot at the transmitting tower. This is still the best source for HD Television.
the second best source is Dish Network as they are using Mpeg4 technology.
No matter what, go ahead and get the HD signals any way you can. Monday Night Football and Discovery Channel (also, HDTV) are reasons enough.
Go to www.antennanet.org and follow the prompts for the kind of antenna you might need for your particular home's location. Also, they will give you compass headings to point the antenna.
