Blu-ray Confirmed As Industry Norm

Posted on | September 19, 2008 | 1 Comment

Blu-Ray technology is not only the latest but, since Toshiba withdrew its HD-DVD competing product from the marketplace, the greatest replacement for CDs and DVDs.

The HD-DVD versus Blu-ray war had close parallels between the VHS versus Betamax contest of the video age in the early 80`s.

This type of battle between huge multinationals is not only interesting for business analysts. The emergence of a clear winner in this battle allows the industry standard to be clearly defined and allows consumers to invest their hard earned cash with confidence.

As interesting as it is to watch two corporate giants slug it out head-to-head, there are some industry analysts who feel that the “format war” is a meaningless sideshow. Many industry insiders feel that more and more customers will choose to download their home movies from either the internet or from their cable TV suppliers.

Without going into too much technical detail, the new Blu-Ray technology is really quite similar to CDs or DVDs. One main difference is that, instead of using a red laser beam to read and write information, it uses a blue-violet beam. It is from this that it derives its name.

The blue laser beam has a shorter wavelength than the “traditional” red one and this allows the laser to be focused on a more precisely defined point on the disc surface. This allows the information to be packed more closely together and effectively increases the storage space of the DVD.

The end result is that all of the additional information required for new high definition television (HD TV) can be fitted onto one disc and the consumer can enjoy high quality movies on their great big LCD TV set. The additional disc space will also allow lots of room for the cut scenes, alternative endings, interactive games, interviews and “the making of…” type of bonuses which have now become expected since the advent of “special edition” dvds.

A dual layer Blu-Ray disc can store around 50 GB of information – which is approximately six times more than a dual layer DVD. Four layer Blu-Ray discs capable of holding 100 GB of information have already been demonstrated and TDK announced that they have created a working experimental disc with a capacity of 200 GB. 250 GB discs are currently under research.

In order to play Blu-ray DVDs a special Blu-ray disc player is needed. Whilst not compulsory, most manufacturers have been producing Blu-Ray disc players which have the capability to play both audio CDs and standard DVDs in addition to the newer Blu-Ray format.

It is interesting to note that the most popular Blu-Ray disc player is undoubtedly the Sony PS3. Ten million of these have shipped so far and it appears as if Sony’s decision to make their new console not just a gaming machine but a home entertainment system has paid dividends.

Considering that Toshiba shipped approximately one million HD DVD machines, the tenfold difference in potential consumer base is so huge that Sony’s triumph was more a matter of time than a great surprise.

In the long term, the adoption of a clearly defined industry standard can only be good news for consumers. There can be no concerns about compatibility and the cost of the players will tumble as other big players commit to the new Blu-ray standard.

The format war has been over for some time now. HD DVD will not be coming back. All the studios now back Blu-Ray. Fortunately this means that almost all the new releases will be coming to Blu-Ray as well. I’ve actually been working with Warner Home Video on some Blu-Ray projects and have seen first hand their committment to making this format as succssful as possible.
