BOXMAN - World of Movies and great actors actresses

Technology, especially in electronics and disc technology is developing at a dazzling speed. Now we have Blu-ray versus DVD, blue laser technology versus red laser used for our DVDs. 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 high definition 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. Early Blu-ray disc players didn’t support Dolby True HD, but most of the current models support it and most of the blu-ray movie releases feature Dolby True HD audiotrack. 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 blu-ray movie releases and there are many more upcoming movies . The Blu-ray disc players are compatible with DVDs and CDs. The best thing about Blu-ray is that it supports high definition video (HD) with high picture quality whereas DVDs support only SD (standard definition) as storage capacity of DVDs 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 DVDs, BDs are 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 Blu-ray format in near future. Hardware support of BD is also much more broader than HD-DVD.

In the battle of Blu-ray versus DVD, Blu-Ray format will overcome 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. Blu-ray format is the best solution for high definition video demands of today. Blu-ray format has the highest storage capacity and high video quality. It seems that next generations will forget about  digital versatile disc but we do not know for how long will blu-ray format will reign 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 disc players for watching new Blu-ray movie releases as it will not possible to find their DVD format in near future. However, the blu-ray movie prices are very affordable. You can find Blu-ray format 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.
