  • HDTV broadcast - Are 1080i broadcasts actually 1440x1080?

    I have heard that there are no 1920x1080 HDTV broadcasts but they are either 720p which is 1280x720 or 1080i, which is broadcast anamorphic 1440x1080.

    Anyone know anything about this?

    What content is available in 1080p?

    Today's high-def broadcasts are done in either 1080i or 720p, and there's little or no chance they'll jump to 1080p any time soon because of bandwidth issues.

    Even the much-vaunted high-def games on the Xbox 360 and the PlayStation 3 are usually 720p native (if not less), though they can be upscaled to 1080i or 1080p in the user settings of those consoles.

    Really, the only commercially available way to get true 1080p output--aside from hooking your PC to your HDTV--is to get a Blu-ray or HD DVD player. All Blu-ray players and some high-end HD DVD models support 1080p output, and--more importantly--the vast majority of discs are natively encoded at 1080p. .
