Blu Ray Technology

Archive for March, 2009

The blue lazer light of the blu-ray technology can squeeze the HD-video of more than 4 hours on a single sided DVD disk. The blu-ray DVD disk format has the latest technology and for next generation is the preferred choice for the storage removal. The blue lazer used in the blu-ray drives give better results and performance than the traditional DVD drives that use the red lazer. The DVD can store up to 4.7 Gigabytes of data, and the single sided blu-ray DVD disk can store 27 Gigabytes of data. The backers of bluray disk that work on the dual layer disk have capacity to store data of 50 GB. The bluray format gives high performance with the high-definition T.V displays. The quality of the picture in HDTV is greater than the picture display by the other traditional televisions.

There is tuff competition between the traditional DVD’s and the bluray format DVDs. The high definition DVD is backed by Toshiba & NEC. While the bluray disc format is supported by group of magor companies like the sony, Philips, samsing and Hitachi. Now that the HP and dell are supporting the blu-ray technology, the sales of the Blu-ray discs will increase and will be the market leader. The DVD+RW efficiently compete against the formats of DVD-R and DVD-RW. Because of the low number of customers the DVD recorders and burners were forced in market even though they were not popular and accepted by the customers. The electronic products like the analog TV and DVD players are commodities. The movie industry as well as the consumers prefers the blu-ray media.

The purpose of the blu-ray BD disk format was to support the recording of the HD video, media applications and the movie distribution. The appearance of the blu-ray BD disk is similar to that of the Compact disk (CD) or the Digital Versatile Disk (DVD). Dual layer DVD can store 9 GB and the dual layer Blu-ray disk can store 50 GB of data. The wave length of the blue lazer used for blu-ray recording is very narrow. Therefore, similar physical space of the disc can hold more volume of data. The high definition multi-media interface helps to connect the media devices (projectors and high definition DVD players). 25 GB data can be stored on a single layer blu-ray disk and 50 GB of data on the dual layer blu-ray disk.

This recording and play back can be done on both the recordable BD-R & rewritable BD-RE disks. By using the BD-AV blu-ray format, the users can use standard definition or the high definition for authoring blu-ray disk that can be played in standalone blu-ray player. The standard definition can be recorded from the analog source. SD can also be transferred directly form the digital video camcorders. So, the high definition material of two hours can be stored on single layer blu-ray disc of 25GB.

The BD-ROM format fulfills the movie industry’s requirement for distribution of the “HD commercial videos” on the prerecorded BD-ROM. It has the features of the Digital Versatile Disk (DVD) and also supports the multi-channel audio, high definition, and features of network. NEC and Toshiba both developed the high definition DVD (HD-DVD) format. Both the blu-ray and the HD-DVD are quite different formats.

There are three types of DVD recorders that work in different ways. Whichever you choose will surely satisfy your recording needs.

A DVD recorder refers to an optical disc recording equipment, which records video into vacuous-writable DVD media. It may exist either as installable drives in computers or as standalone components for use in studios or home theater systems. DVD authoring software is being used in conjunction with DVD recorder drives. Computer based DVD recorders can handle CD-R and CD-RW media. The internal drives are designed with parallel ATA and external drives use USB 2.0 or IEEE 1394.

Standalone DVD recorders can record in all major formats DVD-R, DVD-RW, DVD+R, DVD+RW, and DVD+R DL. Some include hard disk-based digital video recorders (DVRs) to improve ease of use. Mostly, DVD recorders have caused the dropping of that old VCR that we normally used before.

There are several advantages of using DVD recorders than the VCR. Some of them are:
? DVD has excellent audio and video quality.
? It is a conveniently compact disc media, and is far more long-lasting than magnetic tape.
? It can randomly access video chapters without rewinding or fast-forwarding.
? The onscreen multilingual subtitles and labeling unavailable on VCRs.
? It has reduced playback wear and tear.
? It has high-quality digital copying, with little or no generation loss.
? It has improved editing, at any rate on rewritable media.
? It has play listing.
? It has no danger of unexpectedly recording over existing data or suddenly finding no space while recording.
? It has easy to find recordings due to chapter menus.

Because of these advantages, DVD recorders have shown a new dimension of ease and possibilities that left the world of VCRs and video tapes. Despite all these advantages, there is also a disadvantage in the use of DVDs. Recording with DVD recorders should be finalized to watch in the other DVD players. This does not apply to DVD-RAM and DVD+RW disc because these two kinds of discs require no finalization due to the random access nature that they have. Read the rest of this entry »

In our modern world, everything is touched by technology. It makes our lives more comfortable and more convenient, from the way we record things for posterity to the way we communicate. But technology has its failures too. Have you ever tried to fix a scratched disk? Have you ever tried to fix a scratched disc? Is it the same gadget but different name? Well, except for the fact that both of them are circular, they are different – a disk is a magnetic media while a disc is an optical media. This distinction is important because attempting to fix a scratched disk is best left to technical persons while trying to fix a scratched disc can be a do-it-yourself (DIY) project. If you attempt to fix a scratched disk, you might just be doing more harm – it is mechanical damage that you are looking at, not a simple scratch. A professional is best suited to fix a scratched disk than you ever could do. However, trying to fix a scratched disc is easier. You can always clean the disc with water or rubbing alcohol, or you can polish it with toothpaste, or you can wax it. However, not all of these DIY ways is successful and can only lead to more damage if not done properly. It is better to take your scratched/damages discs to a professional, especially when the data contained therein is valuable to you. These discs could be your wedding, your children’s graduation, or a sentimental gift and you want to get the job done by professionals.

Long gone are the times when all we had were compact discs, first for music, then for data storage and movies. The DVDs came next, boasting of what seemed then as tons of data storage.

But as they say, times quickly change, and so does the technology. Personal and commercial demands for data storage — be they for music, movies, games, or software — are outstripping the present capacities of optical discs.

Fortunately, two new players in the optical storage scene have arrived — HD-DVD and Blu-Ray. Both share similarities, and at the same time compete against each other to become the new standard technology for the future. This match-up will eventually determine the successor to the DVD. While it might seem a boon to consumers to have two disc types to choose from, the battle between the two discs might be disastrous to the industry.

HD-DVD

HD-DVD stands for either High Density Digital Versatile Disc or High Definition Digital Video Disc. The HD-DVD’s look is a familiar one — it is 120 mm in diameter, the same size as a CD and DVD. A single-sided HD-DVD can hold 15 GB of storage, while a dual-sided one can store 30 GB. A triple-sided HD-DVD, a huge possibility courtesy of Toshiba, can hold 45 GB.

HD-DVDs use the iHD Interactive Format, which will allow interactive content to be written for the discs.

Blu-Ray

Blu-Ray takes its name from the laser that it uses — a 405 nm wavelength blue laser, which is also employed by the HD-DVD. A single-sided Blu-ray disc, which shares the same diameter with the HD-DVD, CD, and DVD, can hold 25 GB of storage, while a dual-sided one can store 50 GB.

As a counterpart of the HD-DVD’s iHD Interactive Format, Blu-ray will use the HDMV, as well as Java software support to implement interactive menus.

A Comparison

Factors going for the HD-DVD:

The DVD Forum is its big daddy.

The movie industry, which counts among its ranks Universal Studios, Warner Brothers, New Line Cinema, and Paramount Pictures, supports the format.

The giants of the IT industry — Toshiba, NEC, Sanyo, the DVD Forum, Microsoft, and Intel — also support the format.

All HD-DVDs and HD-DVD players are backward compatible, meaning they will still support old DVDs.

It is cheaper and faster to manufacture than Blu-Ray discs.

Factors going for Blu-Ray:

Blu-Ray has the support of the world’s largest electronic companies — Sony, HP, Dell, Pioneer, Philips, Panasonic, Samsung, Apple, LG-Electronics, and Mitsubishi Electric.

There are also companies from the entertainment industry that support the format — Electronic Arts, MGM, Walt Disney, and 20th Century Fox.

The PlayStation 3 will be supporting Blu-Ray discs.

Blu-Ray discs have faster data transfer rates than their counterparts.

Blu-Ray discs have larger storage capacities than their counterparts.

As you can see, each side has its advantages and disadvantages. It’s really too tough to call at this point as to who will emerge the winner. But one thing is certain — the commercial industry disdains this battle of attrition, as any format war has the potential to split the market into two incompatible sub-markets; these smaller markets means that the format war kills off revenues.

In these days of retro futurism and advanced technology; innovations in the field of computers would continue for many more years to come. Invention of automated systems like the High Performance Thinkpads is one such phenomenal step towards equipping the world with rapid gains in every productive process.

In the case of any business process, the effective participation of High Performance Thinkpads in upgrading the overall production is a key feature, as in any decision making process a laptop is found to be the most equipped one.

The Thinkpad is one of the technological marvels of this century, due to its portability features and many important utility. The laptops come with internal modems, WLAN (WiFi) and Ethernet support. As a vast range of connectivity options exist, it maximizes the functions of laptops.

Laptop manufacturers such as Dell, Apple, Samsung, HP, Compaq, IBM, Acer and many others come ahead to offer the users with products that enables them to do a lot of high quality tasks. Samsung laptops, due to their multimedia features and compact design, are preferred mostly by the tech-savvy professional users. Acer laptops are slim and stylish and their multimedia capabilities are brilliant. HP laptops bear stunning looks, smart features and ensure enhanced productivity. The user has to understand his needs and then make a choice among the brands that are available. Aided with advancements in micro-technology, there are processors to fulfill each of the user’s needs.

Thinkpads nowadays come loaded with more than enough system memory and PCI slots to accommodate future enhancement necessities. The users can now have enough space to equip more movies and music, while optical drives in laptops offer supports for files in CD-ROM, CD-RW, DVD-ROM and DVD-ROM formats. As a result of these advanced features, Thinkpads are finding more acceptances from the crowd who were once more inclined towards desktops only.

An electronics company, Onkyo, is planning to introduce an HD-DVD player which, with a price tag of nine hundred dollars, actually costs significantly more than most of today’s current Blu-ray players. Another interesting detail about this device is that it is not a dual format high def DVD player. It’s simply an HD-DVD player.

The wisdom of introducing a nine hundred dollar HD-DVD player is somewhat questionable right now considering the fact that HD-DVD has been engaged in a format war with its rival Blu-ray format for well over a year now. The two formats of optical discs are capable of storing full length movies on single discs in HDTV format with all of their bonus features. The format war is a result of the fact that the two types of discs are not compatible and that the survivor of the format war will make a lot of money off of licensing fees and royalties. In the meantime though, consumers get to suffer the anxiety of which format to choose and whether their formate of choice will go extinct or become one and only format.

There have been a number of technologies that have popped up that could make the format war a moot point from the point of view of consumers, but none of them have caught on so far. Dual format discs for example, are an alternative that provides a Blu-ray movie on one side of a disc and the same movie in HD-DVD format on the other side of the disc so that either type of player can be used, but discs using this technology haven’t made it to market yet. Another answer comes in the form of dual format player that can play discs of both formats. Though these devices actually exist, the two models that are available at this point are so expensive that they make Onkyo’s new HD-DVD player look like a bargain at nine hundred dollars. Indeed if the Onkyo player was capable of playing disks of both formats, it would be a bargain.

Instead of going for the versatility of playing either format of High Def DVD, the Onkyo DV-HD805 goes for high technology in a number of different ways. For example it provides features like lossless Dolby TrueHD and the ability to play twenty four frame 1080p video. In addition, this model will also have DTS-HD Master Audio bitstream pass through modes. (Incidentally, all of these features are supposed to be part of a new line of HD-DVD players from Toshiba.

In addition to all of those features, the Onkyo DV HD805 will have an HQV Reon VX video processor. This addition is supposed to give it a greater capability for upcoverting video and converting 1080i to 1080p through deinterlacing.

While all of those features are impressive, considering the fact that many people are so concerned about whether or not an HD-DVD player is a good purchase at all- and many people are still confused about the distinction between High Def DVD’s and normal DVD’s- this is clearly a product that’s intended for the high end audio-video aficionado.

It seems almost like a Christmas ritual: there’s a Next Big Thing in the video game world almost every holiday season. Last year featured a particularly interesting competition between the new gaming hardware put on the market by Nintendo and their prime competitor, Sony with its PlayStation series.

The Sony PS3 is the high-end, bells-and-whistles choice between the two. It includes high-definition graphics, a hard disk, and a Blu-ray Disc drive that delivers great image quality. The top tier 60GB hard drive version also includes a hefty $600 retail price. Nintendo’s Wii (pronounced “we”) costs $250 and builds in Wi-Fi (but not ethernet). Like the PS3, it has an SD Card slot and can display photos, but its standard-def DVD drive can’t yet play movies (Nintendo and Sonic Solutions are working on that).

What Nintendo does have that keeps it in the game is a unique gaming remote device (the Wiimote) and an enormous library of games. The PS3 enters the market with significantly more horsepower and better graphics, but their game options are, at this point, fairly limited. Wii came on the market with 62 games available; the PS3 opened with an inventory of 20 games.

PC World’s review provides a clean portrayal of the difference between the two systems. The graphics on the PS3 are state of the art 1080p high-definition and present a new level of quality for gamers. The Wii’s graphic capability is limited to standard definition, which is equivalent to the PS2, Sony’s last (and highly successful) video game console. However the Wii has a remote gaming control that utilizes motion-sensing technology, so that the gamers’ motions with the remote are mimicked in the game. If you’re playing football, a pass requires a passing motion with the remote. A sword fight will require a little air-fencing as part of the game participation.

The intuitive nature of the Wii remote is its strength, along with the relatively inexpensive cost compared to the PS3. Wii also has an additional controller called the Nunchuk which is a joystick-type device that works in conjunction with the motion-sensing remote.

The graphics and multiple uses (the PS3 includes a Blu-ray HD DVD player) are what make the Sony product attractive. When they both came on the market, the fact that each relied on separate characteristics to define their value has made for an interesting market contest.

The PS3 is the high-horsepower (and high priced) option on the market. It can handle HD DVDs, play back your digital photographs, and connect to the internet with a built in browser. Its graphics are unparalleled, and it comes with a decent game inventory that will at least get you started. It too has a new controller, one that utilizes a tilt feature that is a token effort at motion sensitivity.

With the Wii, Nintendo decided to forego the digital video wars and focus on a simple box with unique controls that is designed for fun. The Wii can play GameCube games (Nintendo’s last offering) and has been introduced with a new addition to the chart-busting Zelda game series. While the Wii hasn’t done much to upgrade the visual quality of the gaming experience, it has added substantial new dimension to the gaming process itself. It too can be utilized for web access.

Nintendo’s decision to target so-called “casual gamers” seems to have paid off in the short run. It’s too early to pick the long term winner; both companies limited their Christmas product issue in order to ensure sellouts and high product demand. The PS3 definitely has a price-break issue that will offset some gamers’ lust for the best graphics out there. On the other hand, it’s a system with a great future. Wii’s future is now, for the most part, and the product issues an intriguing invitation for a substantially new gaming experience, even if it occurs using last year’s graphics.

If you’re set on getting HDTV, then choose the best buy HDTV. It is a fact though that picking a unit that trumps the rest is never easy. The HDTV you just saw on an ad may not be the best one for you. Here are some things to consider before buying your HDTV:

Basic Information

You can’t buy the best HDTV if you don’t even know what HDTV is. The surest way to find the best of anything is to learn as much as you can about them before paying. HDTV is the product of new technology that allows you to view television shows and DVD in high and clear resolution. It would seem much like seeing the real thing on TV except that images are still two dimensional.

Some areas however are not good places to own an HDTV set. You only get to enjoy great resolution if the shows that you watch are also high definition. Many shows are still in the arena of standard definition. If this is the case, you’ll simply end up having a useless and expensive box with bad pictures. You can determine the best HDTV to buy only if you first determine the appropriateness of an HD unit in your situation.

HDTV or HD-Ready

If an HDTV is not the best choice for you, don’t despair. You still have another alternative. You may instead choose to get an HD-ready set. HDTV typically functions with a tuner that is already built-in and an antenna. An HD-ready set on the other hand would need a separate tuner or box so it can convert digital signals to images. The good thing about having an HD-ready set is that standard definition shows still look great in them.

LCD or Plasma

You would have to choose between a plasma or LCD screen. There is a lot of disagreement over the best buy HDTV when it comes to this consideration. In general, plasma may be a better choice if the room is dimly lit, the TV room is spacious and the TV itself is big. An LCD screen on the other hand would be great if the TV room has clear lighting, the room is cramped and the TV set is not too big. If you want durability, LCD beats plasma.

Aspect Ratio

The aspect ratio of a screen should also be part of your considerations. A lot of new HDTVs come in the 16:9 ratio. Old TVs have a 4:3 ratio. The screen proportion of your choice can affect the way you view a show or movie. Shows set for 4:3 will result in black sides appearing in a 16:9 HDTV set. This isn’t a concern though is you prefer to watch DVDs that typically have widescreen selections.

Rear Projection or Direct View

Old TVs still have rear projection. This means images come out through the process of reflection. TV sets that do not function under the principle of mirror reflection simply show images directly on the screen. HDTV with direct view normally has clearer shows.

Picking your best buy HDTV can be a bit tricky. All you really have to do though is to determine your preferences and whether or not an HDTV is appropriate for you. If you are still at a loss, consider reading HDTV consumer reviews.
