High-definition DVD standard uniform blue along the way universal

Has been plagued by consumers choose two opposing hi-def disc standards competition between HD-DVD and Blu-ray: (Blu-ray), finally came to an end. HD DVD standard of leading manufacturers Toshiba announced today the factory full cut-off, store inventories continue to markdowns, 6 months ago full withdrawal from the market. According to incomplete statistics, the Toshiba HD DVD business in, lose their allies baiyiriyuan, compromised Microsoft Xbox360 video game sales would fall in the month is Sony PS3 transcendence.

HD DVD and Blu-ray (Blu-ray) with high-definition DVD standard, both in technical, are fairly close in on a disc to 5 ~ 10 x more capacity rendered divisors times DVD-quality HD images, and software and game areas, will also contribute to host larger data capacity. Seven major Hollywood studios have been divided into two camps, support both close to the standard.

However, in January when Time Warner's film company-Warner Bros. Announces discard support HD DVD news, immediately triggered a chain reaction. In the seven major film companies, there are five only supports Sony developed Blu-ray DVD standard, only two in support of Blu-ray standards, also support Toshiba HD DVD standard for the development of, and also supports Blu-ray standard. It has been firmly supports HD DVD Microsoft also recently said: will respect the choices of consumers, or will support the Blu-ray standard.

In the future there will be more portable internal Blu-ray optical drive

As the HD DVD standard sponsors — the Toshiba Corporation announced at once, from 15 January onwards to substantially lower HD DVD price drop of up to a maximum of 50%. But this did not reverse the tide, the market research firm NPD figures, as at 26 January week, Blu-ray and HD DVD players in the United States market share of 65% and respectively 28%.

HD DVD's declining popularity also affects Microsoft video game business. The latest statistics show that 1 month in the United States market, Sony PS3 sales reached 26 million units, more than Microsoft's Xbox360 's 23 million units, which affect the consumer's purchasing decision for an important reason is: PS3 game consoles with Blu-ray DVD playback capabilities, and the price is quite reasonable.

Blu-ray victory will significantly promote the sales of the PS3

In the past, consumers select HD drive, the most annoying is the fear of buying to be phased out products, waste of money. Now, consumers simply select Blu-ray standard drive. Industry experts said: "now it is not necessary because cheaper to buy HD DVD cleaning products, for several months, these users will face no discs may look embarrassing situation. While the price of Blu-ray drive is still up in the RMB 3000-5000 Yuan, but soon expected because of scale down to below $ 2000. ”

According to the latest HD DVD business has had a few Toshiba Baiyiriyuan economic losses, and its local Aomori factory will henceforth fully discontinued and will complete withdrawal by June. Data display, Toshiba is now per sold a HD DVD drive up to the loss of several hundred dollars. United States first retailer Wal-Mart recently also renounced selling HD DVD products, only selling Blu-ray DVD products. But in China market, while HD DVD products are not officially for sale, but from Hong Kong, Macao and other underground channels into the product.

· Blu-ray universal prospects still uncertain

While HD DVD quit HD-DVD is already unavoidable, Sony led Blu-ray camp "smile at the end of the day", but the foreign media analysis pointed out: Blu-ray camp also cannot be pleased too early, because they also face normal DVD and network download strong competition, such as business.

Media analysis finds that Toshiba HD DVD, the company gave up helps consumers elimination in the face of high-definition video product awareness, promotion of high-definition video discs purchased and player, which will greatly stimulate high-definition television market.

However, over the years, the HD DVD and Blu-ray contest of two camps, spend too much time. In this period, the Internet video is showing a burst of growth. To Youtube as the representative of the addressable network video site, United States and the world of Internet users have turned out to watch the short video on the network.

At the same time, including Apple iTunes, Amazon, and Netflix DVD rental providers has launched a digital movie download service, although high-definition movie file download is not much, but as the fees and high-definition video download business TV coverage, there is no doubt that consumers will be asked to download the service to provide high-definition movies and TV.

Some analysts even stated that, if the Toshiba's HD DVD has led to the abandonment of the ultimate "death", Blu-ray DVD format will eventually face the fate of the "death" and "kill" Blu-ray's probably digital video download business.

In addition to Internet, cable TV operators, as well as promote IPTV fixed telecom operators have launched video-on-demand service, relying on the advantages of fiber-optic broadband, these service providers may be launched for home users-definition movie download or streaming VOD services, these services compared to Internet video, video discs and player market of "deterrence" and more.

General DVD picture quality has been able to meet most people's requirements

In addition, it should be pointed out that

Is in the world, ordinary DVD players and discs business also has strong vitality, DVD format release films and TV dramas set in myriad, player and discs of the price is very cheap, and the DVD picture quality has many users happy.

As if XP has hampered the popularity of the operating system Vista, ordinary DVD will in the next few years the popularity of impeding Blu-ray DVD. Especially for the Chinese market, the Blu-ray DVD if you want to go into the millions, substantially reduced fear is the only way out.

· Blu-ray HD DVD that can overcome?

Reason one: the capacity and bandwidth advantages are

You might think, and double-layer discs 50GB Blu-ray HD DVD double layer 30GB capacity difference is the most significant difference. In fact, most Blu-ray and HD DVD is not the important differences, but the bandwidth capacity.

HD DVD disc reading speed is 1X, data transfer rate is 36Mbps. Video allows maximum stream is 29.4Mbps, overall synthesis allows for maximum stream is 30.24Mbps. Blu-ray read speed of discs is 1.5X, 54Mbps data rate is. Video allows maximum stream is 40Mbps, overall synthesis allows for maximum stream is 48Mbps.

Bandwidth and data transfer speed, refers to the overall synthesis of the allowed maximum stream. For HD DVD, this value is 30.24Mbps, Blu-ray 48Mbps, this value is.

Budget allocated bandwidth, discs on all sound track, movies, video, picture in picture, subtitles, etc occupied bandwidth and to control the values, not just the user real-time viewing of the content. In other words, even if the user never look at the picture in picture, do not listen to CDs on the Spanish and French sound track, picture in picture and two sound track still occupy a total synthesis of bandwidth.

For example, a movie contains a bar code stream 2Mbps of picture-in-picture, a 5.1 channel of 16bit/48hz of DTHD lossless compression sound track (3Mbps), two-bar code stream to the DD + 640Kbps soundtrack, a 64Kbps comments sound track. Get HD DVD stream limit 30.24Mbps, then left for video peak stream only 24Mbps.

Many video enthusiasts think in a lot of compression difficult scenes, 24Mbps peak stream is not enough. But DTHD sound track assumption is the mother with precision and consistent 24bit/48khz, due to multiple distribution 2Mbps to sound track, video peak bit stream further confined to 22Mbps.

For this problem Blu-ray does not exist. We can see many Blu-ray release is to use no compression of LPCM for soundtrack, released in Europe and some even with two LPCM sound track. HD DVD title, LPCM uncompressed sound track release of little.

Cause two: the manufacturers hope that the unity as soon as possible

In fact, Warner Brothers in the October speech, more performance out of the current dual-format competition the negative effects of unsatisfactory. This negative effect is to let consumers from SD times to DVD high-definition era, confused and upset. They worry about their support for the format became the second Betamax (at that time and VHS video recorder market, competition and ultimately defeat Betamax).

At present, the North American market DVD per capita consumption rates downward trend, those no longer buy DVD users, many BD and HD DVD competition turned to network download (P2P) and how to let consumers quickly into the HDTV market, Chaoyang is Warner Brothers most urgent task, because its parent company Time Warner attaches great importance to the profit, the original Warner Brothers from support HD DVD into neutral is forced to time Warner shareholder pressure.

Therefore, it must choose between one to own incomparable influence to dispel the concerns of the users. In BD and HD DVD, BD more between the upper hand, so according to the Warner brother's stance, to analysis out will be exclusive support BD is not unreasonable.

Warner hopes to make high-definition title to a unified market, as soon as possible so that the business rapidly profit from a business point of view, the market leader in identity to make such a decision, fully able to understand, but chose the BD because if Warner also joined BD exclusive camp, the market will soon be inclined, and quickly will HD DVD extrusion market.

In short, the HD-DVD standard uniform for us consumers is also a good thing, because of Blu-ray disc manufacturers not Sony, therefore we do not need to worry about monopoly, and in General DVD and network download business of double whammy, Blu-ray only prices in order to be more accepted by users.
