I recently purchased my first HDTV a short time ago and am looking for some info in regards to receiving broadcasts in high definition. My television, a Visco 32 inch widescreen, is currently setup with 2 cable inputs. One goes to standard cable reception and other to HD reception. The reception on standard cable is ok but I would like to get more of out the set. My tv is able to get local stations over the air in HD but not others like ESPN, ect... that broadcast programing in HD. My question is, would I need to purchase an HD tuner and an indoor antenna or just the antenna because my television can receive over the air HD? If the HD tuner is necessary, I have been researching the Samsung HD Tuner (DTB-H260F). Thanks for any help or info you can provide.
