Some Valuable Information You Ought To Know Before Purchasing A Blueray Player
Q: Why is it called Blueray?
A: This is because Blueray Disc players and PC drives, and also Sony’s PlayStation 3, use a blue laser beam to read data from discs. DVDs used a red laser. A blue laser can be focused more tightly, so disc makers can put a lot more data on a disc the same size as a DVD. A Blueray Disc can hold up to 50 gigabytes, vs a DVD, which holds lower than 10 GB. With the additional space the video can have up to six times the resolution of DVD, plus you get extra bonus features and enhanced surround soundtracks.
Q: Can you really notice the change between Blueray and DVD?
A: In the event you were to compare a DVD against a BlueRay side by side then most people will comfortably see that Blueray provides a much much improved picture quality.
Q. What equipment do I need to watch Blueray?
A: Besides a BlueRay Disc player you really need a HDTV so you can grasp the full quality and widescreen effect. If you have not got the money to buy a new HDTV then before purchasing a Blueray player to connect to an older TV, examine 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 a Blueray player can send a HD signal to any of them. Ideally you need a 40 inch screen to really enjoy the quality.
What is Upscaling?
Your old DVD collection was designed to be viewed on a CRT screen, and as such was encoded at the lower quality 576i resolution. Because your High Definition TV was designed to display in either 720p, 1080i or 1080p resolution it uses advanced ’scaling’ technology to take a video source and scale it to fit the screen, or ‘upscale’.
Blueray player manufacturers have taken the upscaling concept a step further with the addition of detail to an upscaled source to create sharper better images, boosting the perceived quality of, for example, your existing standard DVDs.
Sophisticated upscaling algorithms are making an educated guess as to what extra detail should be added. Although the extra detail is essentially ‘made up’ the results can be surprisingly good, and can give your old DVDs a new lease of life.
