I'm a little confused on exactly what a digital receiver is. I'm asking this question because my cable company told me I need to have a digital receiver in order to have certain channels. I'm not sure if they meant if my t.v can receive digital channels or if I already have some sort of device that allows me to receive digital channels or some other thing entirely. I have a Samsung 60' plasma t.v and I can receive HD over it ( if that is significant or not). Would anyone know if that type of t.v would have a built in digital receiver or if I need to get some sort of extra equipment to have a digital receiver? Thanks.
