I'm sorry boba, but I feel compelled to straighten this out.

Again, an unthoughtful reply.
JB, You don't know if this member has a STB for a tuner or if it is the displays built-in tuner. Thats first. Second, you have no idea what type of display he has. Both of these facts needs to be known before you jump right in and make statements like that.
First, it isn't "uplink". It is scaled, or upconverted. Second, if it is a STB then the output is user selectable. So if the incoming HD signal is 720p, the user can have the output to 480p, 720p, or 1080i, his choice.
Now depending on the type of display, regardless of the input signal, and this includes built-in tuners, the input signal is virtually moot since the signal will be converted to the displays native resolution. Some LCDs are 720p natural resolution. So in the case of having a STB, a 720p input signal JB, and using your logic that the tuner will scale that to 1080i, it doesn't matter because the TV is going to down convert to its native resolution of 720p. If the display is a newer LCD then the signal (720p or 1080i) will be scaled to 1080p. If a 480p signal is the source signal, that 480p will be converted to 720p or 1080p, again depending on the display type.
If the display is CRT then again, the incoming signal (480p, 720p) is going to be scaled to 1080i.
There is much more but I don't have the time to keep correcting you JB, so this should be enough to get you straightened out on how this all works. I really hope you take my advice and put some real thought into your replies, before just posting willy-nilly.
