RECEIVERLESS HD 

Under certain environments DIRECTV will allow HD programming to be broadcast without Pro:Idiom 

encryption. The programming is in MPEG4 format which some TVs will not receive. It is advised that 

you test TVs on site and provide options for set top boxes for televisions that are not capable of 

processing the MPEG4 signal. Consult with your distributor or DIRECTV area service manager for more 

information on receiverless HD.
