3 Things You Need To Know About Blu Ray Disc Players
Q: Why is it called Blu-ray?
A: This is because Blu-ray Disc players and PC drives, and also Sony’s PlayStation 3, use a blue laser beam to read data from discs. DVD´s used a red laser. A blue laser can be focused more tightly, so disc makers can put much more data on a disc the same size as a DVD. Blu-ray Discs can hold up to 50 gigabytes, compared to a DVD, which holds less than 10 GB. With the extra space the video can have up to six times the resolution of DVD, plus you get extra bonus features and better surround soundtracks.
Q: Can you really notice the change between Blu-ray and DVD?
A: If you were to compare a DVD against a Ble Ray side by side then most people will easily see that Blu-ray’s provide a much much better picture quality.
Q. What equipment do I need to watch Blu-ray?
A: Other than a Blu Ray Disc player you really need a HDTV so you can appreciate the full quality and widescreen effect. If you have not got the cash to buy a new HDTV then before buying a Blu-ray player to connect to an older TV, check the player’s back panel: Not all have the kinds of outputs needed to connect to older sets. Most players send audio and video to newer TVs and displays via a single cable called HDMI. There are different categories of HDTV – 720p,
1080i and 1080p – regardless of which one you have Blu-ray players can send an HD signal to any of them. Ideally you need a 40 inch screen to really appreciate the quality.
