In Google I/O
At the developer conference, Google vice president of engineering Vic gundotra expressed their commitment to the next generation of HTML language, HTML 5. Although HTML 5
The W3C Committee is still in the draft stage and has been discussing the draft for a long time. However, HTML 5 has been widely implemented.
, Or as an experimental demonstration, or has become the core of some web programs.

HTML 5 provides us with different opportunities, gundotra said, he also mentioned that in the past 10 years, the speed of Javascript in mainstream browsers has increased by nearly 100 times, this greatly improves the speed of web programs. Gundotra also provides multiple HTML 5 demos
Contains a YouTube page that is implemented using HTML 5.
. All videos are played in HTML 5.

According to gundotra, the problem with the current video is that there are many things that we cannot control. html 5 provides us with a <
Video> tag, just like using <
IMG> labels are just as simple.

In the demo, there is also a mobile tracking video program implemented using JavaScript, all using html
Video playback. A woman walks in front of the camera, JavaScript
Track her images in real time and mark them with boxes in different parts of her body. In the past, such applications often make browsers crash or lose response, but HTML 5's "Web
Workers "has a strong background processing capability, and the browser can hardly see any card during the program running. This demonstration won a warm applause from 4000 attendees.

Another demo is a first-person design game similar to doom.
,

I/O also provides a mobile demo. In the demo, A Gmail user accesses his/her emails in a mobile browser without a network connection, using HTML 5
In addition, an iPhone user updates their geographic location information in Google Latitude, the latest iPhone
The software will support the geolocation geographic information function of HTML 5.

It is not surprising that HTML 5 is favored by Google. Web is the core of Google. Any technology that makes web programs faster, better, and more practical is
Google is supported, as long as this technology is open enough. However, things are not always optimistic. Many articles have pointed out that Microsoft's latest browser IE8 does not support HTML 5.
The vast majority of features, including video playback, canvas, and Web workers.

Microsoft's response is that it should be cautious with untested technologies, but the closer it is to the fact that Microsoft is on its silver light
Has its own Playback Technology. Microsoft once vowed to support HTML 5, but said it would be far away. However, the gundotra demonstration shows that HTML 5
As you grow up, all other browsers work in this area, which may be a touch for Microsoft.
