Blu-ray, also known as Blu-ray Disc (BD) is known, the name of a next-generation optical disc format jointly by the Blu-ray Disc Association (BDA) is developed. While current optical disc technologies such as DVD, DVD ± R, DVD ± RW and DVD-RAM rely on a red laser to read data and write the new format uses a blue-violet laser instead, hence the name Blue -ray. Blu-ray is currently supported by over 200 leading consumer electronics worldwide, computers, recording media,Video and music companies.

You do not need an Internet connection for basic playback of Blu-ray. The Internet connection is required only for the value-added features such as downloading new extras, watching recent movie trailers, web browsing, etc. It 'also required to run copies of Blu-ray movies that can be approved to be transferred a home network.
So why should Blu-ray, and the answer is simple: HDTV. If you have ever seen in high definition (HD) on a HDTV, then you knowBecause the image is incredibly sharp and vivid as the colors are. In fact, HD offers five times more detail than standard definition (SD). Blu-ray devices range from $ 120 to $ 500 but you can always buy at wholesale prices and save money, this would be a safe option if you wanted to buy blue-ray, as you can not play a great match with your money .
