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!

In late October 2003 the state of California was slammed with the worst wildfire that it had experienced to that date. Twenty people where killed, and damage to local communities and infrastructure was extensive.

The wild fire extended from the Mexican boarder north to the suburbs of Los Angeles. Hundreds of thousands of acres of forest where destroyed. Local vegetation and animal life suffered very large losses and many communities where effected by the disaster. Thousands of different species where decimated by the fire. It is expected that certain of the larger species like elk, and deer, may take several years to repopulate. Even the local salmon stock feeding in the streams running through the burning acreage suffered losses from the fire.

Damage to the area was devastating. 20 people died including one of the fire fighters. Two thousand seven hundred homes and buildings where destroyed and many businesses had to close. This wildfire was to become the most expensive fire to ever hit the United States. Damage to phone lines, and local utilities caused major outages. People were displaced from their homes and many had to leave the state to find accommodation elsewhere during the clean-up period.

The social impact of this wild fire was a bit unexpected. The personal losses incurred by local residences and the tremendous losses to local wildlife resulted in a push by the United States federal government to pass the “Healthy Forests” bill which allocated seven hundred and sixty million dollars to the urban interface between urban cities and forest areas.

The economic impact of this wildfire was catastrophic. One and a quarter to two billion dollars in damages resulted from the fire, making it the most costly wildfire in American history. Losses to businesses and local municipalities amounted to millions of dollars in lost revenues, not to mention the cost of replacing or restoring lost information, and resulted in hardship for many local area residents. The logging industry, of course, took a major financial hit.

Not all natural disasters kill thousands of people, yet most will spread their effects over huge areas and cause massive damage to our fragile and over-used infrastructure. Telephone lines and utilities like electricity, water and even sewage are easily interrupted. Businesses are not able to operate without these simple services. Lost data means lost revenues. Even something as simple as a forest fire can have a huge social and economic influence on our lives. In this case it appears the best offense is a great defense. Always be prepared.
