What is blu ray format

In the present age of technological advancements, a lot of innovative electronics products have been introduced. Blu-ray is a third generation technology that gives a lot of facilities to the users. The Blu-ray discs are gaining popularity these days and they are able to compete with the other optical media storage devices. These discs have much more storage capacities than the traditional CDs and DVDs. The leading consumer electronics group, Blu-ray Disc Association (BDA) has developed these storage media.

Blu-ray discs are popular because one can store a huge amount of data in them. The storage capacity of a single-layer disc is up to 25 GB where as a dual-layer product can hold up to 50 GB of memory space. The high definition movies can be saved in these discs and one can watch them with great ease. In fact, a Blu-ray storage product is able to hold around six times more information than any other media. Blu-ray movies have an edge over the HD DVD films. These can store and play the movies of up to 1080 pixels resolution.

Blue Ray Movies feature high quality videos and therefore provide an exciting experience to the users. The DVDs which are available today do not support the high definition video files. One can not store more than 2 -3 movies in them. Therefore, the Blu-ray discs have an edge over the DVDs because of their value-added features. Moreover, these are more resistant to scratches and dust particles. Such movies can be encoded with a number of codecs. A separate codec is used for each movie. The type of codec is decided by the studio or the company that has developed the film.

The video formats which are supported by Blu-ray discs are MPEG-2, MPEG-4 AVC, SMPTE VC-1, etc. The HD audio formats are supported by these devices. However, it depends on the movie studios to decide the audio formats that has to be used in the film. Some of the popular formats are LPCM, DD, DTS-HD, etc. The large storage capacity gives the choice of including a lot of special features in the discs. Some of the features are menus, video graphics, summary, etc. These value-added benefits bring lot of enjoyment to the viewers. One can directly go to the menu system without stopping the movie. Also, the viewers can see the director of the film discussing the scene when it is being played in the background. They can also update the contents given in the movie through internet and download extras from different websites that provide such facility.

The latest Blu-ray movies can be found from many places. These include movie stores, super markets, CDs/DVDs shops and many others. The online websites also provide the Blu-ray films to the viewers. One can find all the hit movies on these portals at reasonable prices. Many innovative schemes and deals are also offered on these portals that makes shopping much more cost-effective for the users. Some of the latest Blu-ray films are "The Orphanage", "Predator", "Juno", "One Missed Call", etc. The viewers can watch them on their DVD players sitting in the home.

The latest Blu-ray movies discs have got huge response from the viewers worldwide. Some of them have become so popular that they were out of stock within few days of their launch. For example, "Mission Impossible" was a movie that did not have very good sales before the release of its Blu-ray disc version. The new version saw a record sale and became more popular with passage of time. Overall, it is quite clear that the future of Blue-ray movies is very bright and promising. These have brought a new revolution in the entertainment industry and people wait for the arrival of such products.

400 GB of data on a Single Blu-ray Disc

400 GB of data on a single disc. Seems to be quite amusing for some while some would say that it will take time to achieve it. But Japanese electronics giant Pioneer has made it possible. Pioneer has developed world's first 16-layer blu-ray disc, squeezing 25 GB of data on each layer thus totalling to an amazing figure of 400GB.

The currently commercially available blu-ray discs have the storage capacity of 25 GB. Those having two layers can store 50 GB of data. The problem in developing multiple layers disc have been to obtain a clear and stable signal from each recording layer. The frequently visited problems were crosstalk from adjacent layers and transmission loss. Pioneer managed to overcome these issues and developed a disc structure that reduces crosstalk from adjacent layers. Finally it came with a 16-layer optical disc that can play back high-quality signals from each layer.

The good news is that these high capacity discs are backward-compatible and will play on blu-ray disc players. These discs can be read using the same objective lens in current Blu-ray drives. Video game publishers and movie studios can use these discs to take more content on a single disc.

With the development of this technology, Pioneer is putting a green spin on the development. Discs with such enormous capacities mean fewer resources are consumed to deliver the same data or movies on Blu-ray media. For consumers, the main advantage of this technology is the chances of renting an entire season of a television show or collection of movies on a single disc. No need of disc-swapping.
