Comcast was providing Cinemax and many other channels as part of your paid services and you will not receive these unless you are a subscriber. There is a good selection of free broadcast channels unless you live outside city areas. If you do, you will then need an external antenna and probably an amplifier to get more distant signals. Auto programming will not find the channels you were receiving from Comcast so there will be only accidental channel duplication; for example, if your former channel 10 was NBC, it may be channel 7 when receiving signal from an antenna.
There are essentially no more 'Analog' stations still broadcasting, they are now all 'Digital.' The abbreviations 'Std' refers to the aspect ratio (H/W) of the picture area and 'Hrc' and 'Irc' the available resolution or how many pixels and lines on the screen.
