Pardon my ignorance, but how and when exactly do these upscalers work? My TV has a 1920x1080 native resolution (XBR5).

1) I currently use my PS3 for BRD movies, so when I watch a 1080p movie connected via HDMI from the PS3 to the TV there is no upscaling taking place, correct?

2) Same situation as #1, but what if I ran the HDMI signal through a receiver? Still no upscaling? Receiver just passes signal through?

3) I have my 720p/1080i Comcast cable box connected directly to the TV via HDMI. When I press the display button on my TV remote it says 1080i or 720p depending on what HD channel I have on. So what would the TV say if I had the HDMI signal from the cable box routed through a 1080p upscaling receiver?

4) If a 1080p usscaling receiver will upscale my Comcast SD and HD channels to 1080p, is there a noticable improvement in PQ and which resolutions benefit the most from the upscaling? Clearly I'm not expecting to see true 1080p PQ from any of these upscaled resolutions.
