A interview going on for glorious definition?
you can fit lots of music notes to a standard disc using mp3 so why could the hd resolution of 720 and 1080 not be compressed and put onto a standard disc.after all your dvd player is not reading the amount of pixals it is just reading coding the same as a computer does.is here any way that it can be done using a divx type coding
Answers: Well, you COULD use divx, but the video element will suffer. Ever see a VCD? That's basically what you'd grasp.
Remember, a HD movie contains 6 times the resolution of a normal DVD, so what be ~4GB in 480p, is closer to 22-25GB surrounded by 1080p. HD movies aren't recorded within 720p or 1080i - the player or your TV will downscale the picture accordingly contained by those cases.
So, there be a need for a larger size disc, and that's what HD-DVD and Blu-Ray provide.
