Explanation of the Two Major Formats: Blu-ray Disc or advanced optical Disc

The gradual evolution of the optic disc technology saw the advent of the Dvds. Dvds changed the entire entertainment experience. Citizen could watch the latest blockbusters from the relieve of their homes with their latest high definition Dvd players, with unmatched photograph capability and audio output. Dvds are everywhere, so too are Dvd players. You have the high definition Dvd players with all sorts of features. The time to come lies with emerging technologies like Blu-ray and advanced optic discs.

Explanation of the Two Major Formats: Blu-ray Disc or advanced optical Disc

Blu-ray Discs

Blu-ray, popularly known as Bd or blue-ray discs, is a next-generation optic disc that has been advanced by the Blu-ray Disc relationship (Bda). The group consists of important buyer electronics giants, Pc and media manufacturers, like Philips, Samsung, Sony, Sharp, Hp, Hitachi and Panasonic, to name a few. The format enables recording, rewriting and playback of high definition video (Hd). One major benefit that the technology has over conventional Dvds is that it allows for more warehouse capacity. It can hold up to 25Gb on a single layered disc and 50Gb on a dual-layer disc. The technology also incorporates advanced video and audio codes for the greatest high definition viewing experience. The name Blu-ray is used because the format uses a blue-violet laser, instead of a red laser as in the case of primary Dvds.

Another major benefit with Blu-ray format lies in the fact that the entire technology is backwards compatible. You can now play your old Cds and Dvds straight through a Bd/Dvd/Cd compatible unit. The blue-violet laser has a shorter wavelength than a red laser, which enables it to focus on a disc area with greater precision. The data is also packed on the surface of a disc more tightly. This explains the disc's capability to store more data, even though it is of the same size as a primary Cd.

The technology is supported by some of the world's important manufacturers. In fact, many major movie studios have already announced titles with Blu-ray in them. Warner, Disney, Sony, Mgm, and noted are among the important studios who have embraced the format. Some of the noted titles consist of movies such as Desperado, remarkable Four, Hero, Kill Bill, and Lethal Weapon. Sony has in fact come out with a mass produced model, which has already hit the market. Several other important brands have also announced their intentions to begin models with the Blu-ray format.

The Blu-ray movie codes are separate from that of Dvd region codes. So you have North America, South America, Japan, and East Asia excluding China forming the Region 1, followed by Europe and Africa forming the Region 2. China, India, and Russia make up Region 3.

One major disadvantage with Blu-ray format is that many suitable Dvd players are unable to read the discs. This qoute is being rectified in the form of backward compatible players though. The growth of Blu-ray discs is incredible to drive the growth of the home theater segments to added unprecedented heights.

Advanced optic Discs

Yet an additional one technology, or format to be precise, which is giving the Blu-ray format a good run for its money, is the advanced optic Disc (Aod) format. It has been created by Toshiba in collaboration with Nec. Even though it is determined the main rival to the Blu-ray format, ironically, it is being supported by the Dvd forum that includes nine members, who are 'Blu-ray disc founders.' While a single layered disc using this technology holds nearby 15 Gb of data, a double layered disc would hold 30 Gb of data. One can compress 20 Gb of data in the recordable version.

This format too uses the blue laser, the disagreement being the higher compression of the video stream. One major benefit of the Aod format over the Blu-ray format is the fact that the Aod format will cost you less. Although not a great deal is known about the format as yet, if one were to go by the Toshiba-Nec team, then the players would be smaller than the ones using Blu-ray format.

Capable of playing high definition Dvd, some models using the Aod format from Toshiba have already hit the markets. They are practically priced nearby 0-0. Details available on the progression of the technology are sketchy, however, while this point in time.

Industry Trends

Industry analysts believe that the Blu-ray format would hold sway over the masses in the near future. There are other associated technologies which are also trying to break in, like the Holographic Versatile Disc (Hvd) technology. This technology is still at a investigate stage and claims to have greatly increased warehouse capacity than both Blu-ray and Hd Dvd formats.

Researchers are also working on many other technologies. Some of them are claiming to be working on a technology with a warehouse capacity that is, believe it or not, 100 times that of a Dvd. The technology involves manufacture disks with a three-dimensional structure rather than the primary two dimensional Dvds. With data warehouse and security assuming importance, investigate on varied lines is being carried out. Most of these investigate activities have the potential to revolutionize the home theater market.

With convergence of varied features being the trend nowadays, there are Several models of Dvd players already available in the market, which have gaming options apart from playing Dvds. The addition popularity of home theater systems is driving the investigate in this field.

Movie makers too are increasingly dependent on digital formats for both film manufacture and projection. Digital video and audio outputs are determined far more first-rate to the existing primary methods, and offer viewers an enhanced movie experience.
