Blu-ray Movies: In The Highest Definition Ever

Blu-ray is capable of storing and playing movies in 1080p resolution. In many respects, 1080p resolution is called “True High-Definition” or “Full High-Definition“. A Blu-ray disc can store and play roughly around 5 to 6 hours of high-definition content (1080p resolution) and around 24 hours of standard-definition content (480i or 480p resolution). With the capability of storing up to 50 gigabytes of data, you will be able to watch an entire Blu-ray movie with crisp clarity.

But what exactly is 1080p resolution?

Well, the number 1080 means that there are 1,080 lines of vertical resolution. Generally the larger number of vertical resolution lines, the sharper and more detailed the image. The letter “p” stands for progressive scan. Progressive scan (a.k.a. non-interlaced) is a way to transmit, store, or display moving images. The other method of transmitting, storing, or displaying moving images is called interlace. Interlace is represented by the letter “i” (1080i). Interlace was created to improve video quality without consuming more bandwidth. However, progression scan is superior to the interlaced method because the progression scan method transmits, stores, or displaying moving images by processing all horizontal lines sequentially each frame. While the interlace method processes every other line in one frame, then the rest of the lines in the next. This results in reduced horizontal resolution. While the interlace method isn’t all bad, and the progressive scan method isn’t prefect, when it comes to which provides the best picture quality, progressive scan is the way to go.

HD DVD has the capability to store and play movies in 1080p, so why is Blu-ray better?

The answer to that question requires one word, space. A HD DVD has greater limitations than Blu-ray. HD DVD discs and Blu-ray discs come in two forms, single layered and dual layered. Please note that the higher the number of gigabytes, the more data that can be stored. A single layered HD DVD disc has a maximum capacity of 15 gigabytes and a single layered Blu-ray disc has a maximum capacity of 25 gigabytes. When these two discs are dual layered, their maximum capacities are doubled, with a HD DVD at 30 gigabytes and Blu-ray at 50. So, at most Blu-ray can handle 20 gigabytes of additional storage, and with a world that is constantly changing, that extra 20 gigabytes can make a world of difference.

Blu-ray movies: In the highest definition ever!

Blu-ray movies have the edge over HD DVD movies. Due to the lack of space, HD DVD will eventually fall further and further behind. On the contrary, Blu-ray will reach its full potential, being able to store more of the finest details and stunning visuals. Blu-ray has reached the highest definition ever!
