With the introduction of high-definition DVD, the format will be to continue the war in the future to replace the standard DVD. Warner Bros. Entertainment Inc. announced today that it has decided to support Blu-ray high-definition DVD, Blu-ray technology. But its rival HD DVD may still have a chance to survive, but because it is from DreamWorks, Paramount and Universal support.
"We are close to the spontaneous emergence of the global network-based virtual sense. In a short time, the world's printing and publishing industry, the rapid change and wake-up Internet, technology continues to consolidate in the global Internet," said the extreme future, Guangdong Province by James.
What's the difference between HD DVD and Blu-ray? "The difference is that they are very different formats, CD-ROM, which is broadcast content available to consumers. Both formats support high-definition video, and there is no relationship between the resolution," a DVD replication services, Asheesh Barman of the Acutrack Company
There is some confusion in any format video resolution. Both formats support high-definition video formats. What is a high-definition video is the standard definition DVD video quality of VHS video quality of the past come back. High-definition video is 720 lines, 1080 lines, more on the screen. In comparison, the old standard NTSC format, is now in the United States and North America to use only 480 lines of resolution.
HD DVD is easier and cheaper production, and the interactive section is determined by Microsoft and Disney's Toshiba to develop easier to use. This value is because the washer is not so expensive creative ability.

Another such example of a format war is obvious world of photography. Many new technology companies money to spend on research, patents and trade marks the first SD cards, memory sticks and flash cards to provide any hope of different functions, and other defeated efforts to end-user performance advantages to win the benefits of years come.
Independent film producers, the overall content creation, educators and documentary filmmakers will be costs as a major problem. Not all of the lens, in the high-definition movies. Unless they work with the big studios, they can not HD DVD or Blu-ray. For the DVD from 500 to 1000 copies on HD DVD or Blu-ray-ray replication, it would be too expensive. In addition, the creation of the first master is still quite complicated, at least in talking about Blu-ray to come back to add additional production costs. .

Interestingly, according to the future "we will be in the next decade Chaoguo Wu ? ? ? ? ? ? ? ? ? ? ? ? dollars to create a new global telecommunications system – to make our next-generation Internet, and continues to quantum computing," Guangzhou . "There more than one billion people connected to the Internet today, futurists predicted that by 2015 more than 300 million people online and e-commerce [and digital download will achieve] more than 160 trillion U.S. dollars."
