Blu-ray can store and play movies in 1080p resolution. In many respects, the 1080p is called "true HD" or "Full High-Definition". A Blu-ray disc can store and play roughly 5-6 hours of HD content (1080p) and approximately 24 hours of standard definition content (480i or 480p resolution). With the ability to store up to 50 gigabytes of data, you'll be able to watch an entire movie Blu-ray player with great clarity.
But what exactly is 1080p?
Well, the number 1080 means that there are 1080 lines of vertical resolution. In general, the greatest number of lines of vertical resolution, the sharper and more detailed image. The letter "p" means progressive scan. Progressive scan (aka non-interlaced) is a way to transmit, store or display moving images. The other method of transmission, storage or display of moving images is called interlacing. Interlace is represented by the letter "i" (1080i). Interlace was created to improve the quality video without bandwidth. However, the increase of scan is greater than the interlaced method because the progression scan method transmits, stores, or display moving images by processing all the horizontal lines sequentially each frame. Although the method of interlacing processes all other lines in a frame, then the remaining lines in the next. This results in reduced horizontal resolution. Although the method of interlacing is not bad at all, and the progressive scan mode is prefect when it comes to what provides the best image quality, progressive scan is the way forward.
HD DVD has the ability to store and play movies in 1080p, so why is Blu-ray better?
The answer to this question requires a word, space. An HD DVD has more limitations than Blu-ray. HD DVD and Blu-ray discs are available in two forms, single layer and double layer. Please note that as the number of gigabytes, the data most likely to be stored. A single layer HD DVD has a maximum capacity of 15 GB single layer disc and a Blu-ray has a maximum capacity of 25 gigabytes. When these two discs are dual layered, their maximum capacities are doubled, with an HD DVD at 30 gigabytes and Blu-ray 50. Thus, most Blu-ray disc can handle 20 gigabytes of additional storage space, and with a world that is constantly evolving, that extra 20 gigabytes can make a world of difference.
Blu-ray movies: In the highest definition ever!
Blu-ray movies have the advantage over HD DVD. Due to lack of space, HD DVD will fall increasingly behind. Instead, Blu-ray will reach its full potential, being able to store more fine details and stunning visuals. Blu-ray has reached the highest definition ever!
