That is not possible since HD-players use HDMI for connecting to the television. It wouldn't be very useful to connect HD-players to SDTV's, because that way the player has no advantage over a standard DVD player.
Yes you can. BluRay players have an HDMI output for use with HD televisions and almost all have an analog output that can be connected to standard definition television. The output won't be HD of course, but you do get to watch the disc.
Bluray
BluRay discs carry high definition television and therefore store data in a high density format. A standard definition DVD player will not recognise a BluRay disc and will simply report an error if one is loaded. On the other hand, a BluRay player will not only play BluRay discs but will also handle standard DVDs. Most will also recognise and play CD format discs. Most Bluray players will also down convert the HD signal from a BluRay disc so that it can be viewed on a standard definition television. In this case, of course, the image quality will be the same as any other standard definition signal. To benefit from the high definition signal, an HD television is also required.
No. All current 3D disc content is HD and so use Bluray discs. You have to have a 3D Bluray player.
Yes you can. Virtually all Bluray players have an analog output which is standard definition. This can be connected to the video input of any television and you will see a standard definition image from a Bluray disc. The quality won't be as good as is on the disc of course but at least the disc will play. It is normally possible to set up the HDMI connector to output a standard definition signal. This is probably not of much use as almost all televisions that have HDMI inputs will also accept high definition signals. It might also be worth pointing out that standard DVDs will also play on a Bluray player. Using the analog output from the player with a standard DVD playing will give the same quality of image as any standard DVD player.
Most Bluray players can play either DVDs or Bluray discs using a standard definition television. Almost all Bluray players have an analog composite, S-video or component output that can be used. Before purchasing, check that the player has an output that the television can accept. Note that the quality of the image will be standard definition and not HD. All Bluray players today limit their analog outputs to SD so even with an HD television, analog inputs will not deliver HD images.
Yes. Blu-Ray players will only operate with a standard definition television using the analog outputs on the player. The outputs are standard definition of course, so the HD quality of the BluRay disc won't be seen.
No. DVD quality will be displayed whether the player is a DVD player or a Bluray player. DVDs won't be the same quality as a Bluray disc of course.
A Bluray disc stores five times more data than a DVD. Therefore, a DVD will not have the capacity to store the contents of a Bluray disc.
No
You will require a Bluray player to play a disc. To watch content in high definition, you will need an HD television with an HDMI connection between them. However, Bluray players have analog outputs to allow a standard definition signal to be connected to non HD televisions.
To watch a Bluray disc in high definition, an HD television is needed. However, almost all Bluray players have an analog, standard definition output that can be connected to televisions that are not HD and do not have HDMI inputs.
A 2 Disc DVD movie can fit on a single Blu-Ray Disc and be in HD which is more GB. The length of a Movie remains the same, but the Blu-ray has more room to add extras besides the movie.
