can you watch blu ray discs on 720p telivision?

do regular dvds look better on 720p even though they arent hi def?



Answer
Most definitely you can watch Blu-ray in 720p! Blu-ray has a maximum resolution of 1080p, even 720p will be much clearer than a standard DVD.

Depending on the upscaler and DVD/Blu-ray player you have, regular DVDs will probably not look "better" on a high definition TV. Regular DVDs have a maximum resolution of 480 (PAL) or 576 (NTSC) , so what the player would do is scale and fill in data to populate all 720 vertical pixels.

Some players that has the Silicon Optix REON chip has great upscaling that makes standard DVDs look really good. But remember it is still trying to fill in data that is not there before.

Also keep in mind too, even if you don't have a upscaling player your TV will do the job of scaling the information to fit your TV. Remember that some where along the line, the regular DVD's 480p will have to be stretch to fit the DVD. Higher end TVs will have great upscalers where you don't even need a "upscaling" dvd player. Most Blu-ray players again are pretty good upscalers for normal DVDs as well.

Quality difference between playing a regular DVD on Blu Ray player vs. a Blu Ray DVD on Blu Ray player?

I know Blu Ray players can upconvert regular DVDs, so is there any major difference in picture between a regular DVD or Blu Ray DVD when both are played on a Blu Ray player?


Answer
A regular DVD on an upconverting 1080p DVD player won't match the resolution of a true Blu-Ray Disc on a Blu-Ray player. On the other hand, a Blu-Ray player won't give better resolution than an unpconverting DVD player in upconversion of a regular DVD.

In my opinion, and from my experience, it would be like comparing a 1080i (1280 x 1080 = 1,382,400 pixels) resolution to a 1080p (1920 x 1080 = 2,073,600) resolution. Therefore, an interlaced format is nearly half the resolution (i.e. every other vertical line is "interlaced" or blended as opposed to "progessive" which is where you get every line).

Bottom line, compare for your self by experimenting between the different choices available on the video market and you decide whether the difference justifies upgrading your system or not.

Happy viewing!
