We really need more capacity?

The cynics among us can say that it is just another way for computer and electronics industry to sell us all something new. While there is an element of truth in this, as not everyone needs the additional capacity but computers, software and applications do not continue to be increasingly data hungry.

Many users will welcome the additional amount of storage that have both formats, as they are always at full speed with DVD. The new formats will be the equivalent of five and ten times the size of a DVD. Besides this, the fastest speed of broadband are allowing users to download more and more data.

The fast transfer rate of blue laser disc – coupled with the greater capacity of a disc – also makes it ideal for storing applications, medical records and activities in high resolution that need instant access or retrieval.

First of all, let’s take a quick look at the differences between the two formats that both use a blue laser disc recording:

Blu-ray

Blu-ray is supported by over 100 companies that are members of the Blu-ray Disc Association (http://www.blu-raydisc.com). Key members include: Sony, Pioneer, HP, Dell, Philips, Mitsubishi Chemical, Walt Disney, TDK, Hitachi, 20th Century Fox and Apple.

initial storage capacity of a Blu-ray will be 25 GB (or 135 minutes of high definition film and two hours of bonus standard definition quality) for a single layer and 50GB double layer (or three hours of film and nine hours of bonus materials). The prototypes have been developed by TDK that will take this to 100GB on a single side. The Blu-ray group estimate the technology will be viable as a format standard for 10-15 years.

Similar to CD and DVD, Blu-ray will be available as recordable once (BD-R), rewritable (BD-E) and a pre-recorded disc format (BD-ROM). There are also two other types of Blu-ray discs that are contained in cartridges for use in the transmission and data storage industries. These are called PD and PDD, respectively.

Blu-ray disc products will be launched to cover three main areas of application:

1. Use of computer desktop applications and home video.

2. Professional broadcasting.

3. Professional data backup applications.

Blu-ray discs are manufactured using a single substrate disc with the recording layer very near the surface of the disc. This should result in less potential distortion, higher precision and shorter production times and costs.

In terms of compatibility, it is likely that the Blu-ray disc products will play both DVD and CD formats. It is also expected that the PC Blu-ray recorders and Mac will also be able to record onto CD and DVD. Sony recently announced that their next generation console PlayStation 3 will have capacity of Blu-ray.

High Density DVD

There are fewer companies in the HD-DVD Promotion Group (http://www.hddvdprg.com), but still no less significant ones. The companies include NEC, Toshiba, Sanyo, Thomson and Universal Pictures. The format is also supported by the DVD Forum.

Initial storage capacity is about 15/20GB, 30/32GB and more than 45 GB dual layer. In its current form, the capacity can go beyond that because of the position of the recording level, which is farther from the disc surface.

Disc manufacturers will be able to transition to HD-DVD more easily as it is a disc similar to DVD. However, the limited capacity could see it ending up as a temporary solution and manufacturers will inevitably need to invest in production lines Blu-ray.

Like DVD, HD-DVD is produced by bonding two surfaces (substrates) together. E ‘likely that the HD-DVD devices will also be able to play your DVDs and CDs. The discs will be available in a DVD (HD-DVD-R), rewritable version (HD-DVD-RW) and pre-recorded (HD-DVD-ROM).

Because you can expand the capacity blue laser?

With the same size as the surface of the disc is a CD and DVD blue laser disc can record and store more information using a laser beam with a much smaller focus of CD or DVD. This laser can record smaller and higher density pits, allowing more room for data storage.

A closer look at Blu-ray

Within the family there are three Blu-ray discs available that are optimized for specific applications. The main question and its use will be produced for the standard Blu-ray, but there are also two other types of Blu-ray discs available that have been specifically developed for the transmission and storage of market data:

Professional Disc (PD)

PD has been developed specifically for the markets on news gathering and broadcast.
The products are already introduced by Sony. These include: a recording and editing system – ENG (Electronic News Gathering) – as well as the XDCAM series of professional camcorders.

PD has a faster data transfer rate, 72 Mbps compared to 36Mbps, compared to the standard Blu-ray and is seen as a substitute for traditional tape loaded broadcast cameras.
The disc is rewritable and contained in a cartridge for greater protection in field use. PD disk media is manufactured by both Sony and TDK.

Professional Disc for Data (PDD)

PDD was developed as a substitute for traditional magneto-optical (MO) applications, such as juke boxes for online access or data archive and storage. PDD is physically almost identical to the Professional Disc (PD) and is available as recordable and rewritable. The disc is contained in a cartridge for protection and ease of use by the robot at any juke box or library system. Typical users are doctors, banks, government and telecommunications companies who need fast Internet access to large amounts of data or information.

Standard Blu-ray

Standard Blu-ray will be the main Blu-ray product for mass use in consumer recorders and players, drives for PCs and game consoles such as PlayStation 3. The support of the disc can be provided “naked” and is not contained in a cartridge as a result of manufacturing a hard layer protective layer. The first manufacturer to introduce this is TDK with their technology ‘Durabis’ coating.

Blu-ray discs are equipped with encryption and copy protection within the hardware and media production level to minimize piracy and illegal copying.

Why the need for a protective layer?

An immediate reason for the protective layer that is packing more data on the surface of the disc format of the recorded data can be more sensitive to reproductive problems caused by damage from handling, scratches and static. Furthermore, in order to obtain the maximum capacity of Blu-ray Disc and ensure accuracy, the level of registration of a Blu-ray is produced closer to the surface of the disc is DVD and HD-DVD. This means that the Blu-ray has a much higher capacity than other blue laser discs such as HD-DVD, but this does not mean that the disk needs to be encased in a caddy like PD and PDD or protected by a additional layer of coating. Being able to produce a disc that can be used in its ‘naked’, without a caddy it will ensure a wider use and adoption of the Blu-ray. This is because the disk is used in a number of different drives and consumer electronic products. Disposing of the caddy also drastically reduce the production cost per unit and the end users.

Structure comparison disk

With the need to have a protective coating on a disc ‘naked’ Blu-ray Disc, TDK were the first manufacturer to introduce an average finish of ‘scratch’. This has been available for some time as an option on their DVD product range, but recently have taken this technology even further with the latest coating technology called ‘Urbis’. The advantages of the lining of the ‘Urbis’ means that the discs can be used without a caddy and are much less likely to be damaged by scratches, UV rays, fingerprints and dust attracted by static electricity.

And finally …. When everything becomes available?

Toshiba Corp. has announced a 2006 commercial launch date of March for the first HD DVD player in the United States.

Blu-ray disc recorders were launched in Japan in 2003. Blu-ray is available in Japan in caddy format and should be available in the U.S. by 2006 summer.

Professional Disc (PD) for the transmission has limited availability. E ‘especially during testing and experience in high-definition TV projects from large TV production companies and authorities.

Professional Disc for Data (PDD), which is used for archiving and backup has limited availability.

Both the Blu-ray group and HD-DVD group are talking together on a single format to avoid a collision format. However, as the proposal for each of the parties seems to be that the other down to their size, it seems unlikely that it will lead to ‘peace in our time’.

The new Xbox 360 dimensions are significantly smaller than its predecessor. This console is very similar in size to the Sony PS3 Slim. The weight of the Xbox 360 Slim was also decreased, making it some what lighter than before. The new Xbox 360 runs much quieter and much cooler with the CPU fan and strengthened.

The new Xbox 360 now has five USB ports, more than its predecessor, 2 of which are located in front of the console and the rest at the bottom, with the addition of an AUX port to connect the control system Kinect.

The peculiarity of the new Xbox 360 is the Kinect sensor bundled with the console for both the 4-GB or 250 GB version. You do not need any additional equipment to play the game when using the sensor Kinect. All movements of the hands, feet, body, your voice is the controller. On the other hand, PlayStation and Nintendo Wii Move can also provide motion games, but is still holding the two controllers during game play.

Xbox 360 vs 4GB Slim 250 GB Xbox 360

4 GB and 250 GB versions both have the same design, both have 5 USB ports and port Kinect. In my opinion there is no justification for a price increase of $ 100. The 250GB hard drive is very nice to have but most people who are serious about storage know how to install a different hard drive yourself or know someone who can do it for them with no problem.

The HDMI cable is the best interface element for digital data transmission and highly recommended component to use in watching high definition (HD) content. Nowadays, most HD televisions can hand over this cable connector including those early versions of HD TVs. It is a technology for direct high resolution and good sound quality features. Important things to consider are the following:

1. HDMI cable version

There are different cable specification versions; version 1.0-1.2, version 1.3 and version 1.4. The higher version has higher increase in bandwidth and capabilities to transmit data over the cable. Version 1.0-1.2 is recommended to those early versions of HD TVs. Version 1.3 is recommended to provide good and high quality resolution, color and sound. Version 1.4 supports 3D technologies and is recommended to 3D cinemas and family HD TVs for 3D movies, animations, or effects.

2. HDMI cable connector type

Types of connector vary with different sizes. Mini and micro port sizes support HDMI version 1.3 and 1.4, respectively.

3. HDMI cable length

The cable has no maximum length because it depends with the quality of construction and conductor materials but usually it varies from 10 to 15 meters. However in real time use, it will not consume the 15 meters long. Therefore, it is best to know the recommended measure and could be from 50cm up to the edge.

4. HDMI cable thickness

HDMI has two cable categories: category 1 and 2 which both have been tested and classified as standard and high speed cables, respectively. However, you should give emphasize with the thickness of the cable. Too thin cables are not recommended because it may affect the signal quality and the shield is too small that may lead to wire problems and even HD output performance.

5. HDMI cable brands

There are lots of brands available in the market such as Akihabara, Sony, Toshiba, and others which we all know expensive but in high quality. Considered brands as one of factors in choosing cable.

There are many things that should give attention in choosing cable and what are stated above are suggestions that should give consideration first. Following helpful tips could be one of the reasons to become successful in choosing appropriate cable.

Since PS4 was rumored, there were many kinds of thought regarding its design, how it looks, and also its capabilities. But, one of the major things in PS4 was predicted to have presence of amazing 3D capabilities.

Sony is not really going to let out a single word about PS4, but lately they were seen really active showcasing some incredible 3D game demos, which were nowhere even close compared with the best games ever seen before.

Until today, none of gaming consoles have been able to utilize the 3D capabilities to a great degree, and interestingly, Sony has not promised anything about PS3 being able to play these great 3D games in the future.

But, the experts are predicting that Sony PS3 can receive some firmware updates shortly, which might allow PS3 to let gamers enjoy 3D games without actually spending something large out of their pockets.

However, Sony has not officially confirmed anything about the firmware update for PS3, things are pretty suspicious. Some of hardcore PS fans are speculating 3D integration in PS3 with a firmware upgrade will be Sony’s trump card to once again join the battle of domination in the gaming arena. At present, PS3 is almost down and out compared with its rivals: X-Box 360 and Nintendo Wii, but it seems that Sony is preparing something very promising.

At any rate, Sony’s demo on those cool 3D games has made it pretty obvious that they will definitely let the gamers enjoy the 3D games, although it might take sometime after all.

Therefore, it is likely that PS4 would have some amazing 3D gaming capabilities, but maybe you won’t really need to wait that long for the launch of PS4 to enjoy these attractive 3D games because most likely PS3 will get firmware updates. You can also discuss this issue in Playstation 4 Forum.
