Blu-Ray Vs DVD By Ozlem Yegengil

Technology, especially in electronics and disc technology is developing at a dazzling speed. Now we have Blu-rays with blue laser technology instead of red laser used for our DVD. It seems that the term 'DVD' standing for Digital Versatile Disc will be replaced by the term 'BD' standing for Blu-ray Disc. It has already begun entering our lives as well as our terminology.

When we take a look at its advantages, the storage capacity of this next-generation format BD is five times more than DVD format. The capacity of a single layer is 25GB and dual-layer has 50GB capacity. Blu-ray provides read-only (BD-ROM), recordable (BD-R) and rewritable (BD-RE) formats. A dual-layer can contain 9 hours of HD video. It supports all the codecs that DVD format supports and in addition, it supports Dolby True HD, DTS-HD and DTS Digital Surround audio codecs and MPEG-4AVC and SMPTE VC-1 video codes. The video bit rate is maximum 40.0 Mbps while DVD has only 9.8 Mbps video bit rate.

This technology is developed by a group of several huge companies such as Warner Bros, Walt Disney, Sony, LG, Dell and Apple. Many studios have begun releasing movies on BD and there are many more upcoming movies . The Blu-ray players are compatible with DVD and CD. The best thing about Blu-ray is that it supports HD (high-definition) video with high picture quality whereas DVD supports only SD (standard definition) as storage capacity of DVD is not sufficient for HD. Besides, it has a menu system that enables you to see anything in the menu while the movie is playing in the background. Also you can jump to any section on the BD easily. Another advantage of Blu-ray is its hard-coating. Unlike DVD, BD is scratch resistant.

Actually, HD-DVD is similar to BD, using blue laser technology. However, audio and video quality of BD is much more better. Also HD-DVD is not supported by most of the giants in the market. You will not be able to find the movies you would like to watch in the formats other than BD in near future. Hardware support of BD is also much more broader than HD-DVD.

Blu-ray will succeed the DVD format in a short time and DVD will lose its popularity as BD is supported by the leading movie studios and PC manufacturers. BD is the format of today but we do not know for how long and when it will be replaced with what. This market is full of competition and leading companies come out with something new everyday.

It is unavoidable to own Blu-ray players for watching new releases as it will not possible to find their DVD formats in near future. However, the Blu-ray movie prices are very affordable. You can find BD formats of your favorite movies starting from $6 - $7 up to $50 - $60 for the box sets and it is worth for its quality and new features.

DVD Players- When Multi-Disc Players Make Good Sense By Christine Peppler Platinum Quality Author

Now that DVD players have been popular for quite a number of years, prices are quite reasonable. Single disc players well under $100 abound providing options for almost every budget. For many people a single disc player meets their needs nicely as they can view only one DVD movie at a time anyway. For some consumers however, other features are well worth a few extra dollars.

One of the first options buyers have to consider is whether or not a multi-disc or mega storage type of DVD player would be a good choice for them. While some multi-disc players allow users to keep up to 4 or 5 discs in the player at any given time, others can store up to 400 discs.

Multi-disc DVD players offer four primary advantages for consumers:

• Ease of Use: Multi-disc DVD players allow users to keep multiple discs in the player which can eliminate time spent shuffling through discs and loading them. Most have good search functions that allow users to easily find the disc they want and to initiate play with the push of a button from their remote control. In the case of a large collection of discs this is a particularly attractive option.

• Saving Space: If a user has a large collection of discs, a mega storage DVD player can potentially store their collection eliminating the need for additional shelving on which to house their collection. All discs are maintained in the player and available for immediate access.

• Dual Use: Most DVD players offer the ability to not only play DVD movies but audio CDs as well. Users can switch between movie viewing and listening to audio with the push of a button. With a multi-disc DVD player, many owners opt to forgo the purchase of a separate CD player completely.

• Something for the Whole Family: Face it, not everyone living in the house has the same taste in music or movies. Being able to store and play multiple discs, can be the only fair way to give quick and easy access to the collections of multiple individuals.

Certainly, there are many choices to make and features to consider when selecting a DVD player. Deciding on the disc capacity requires only a simple look at the size of the person's DVD/CD collection and determining whether or not quick and easy access to those discs is critical.
