2002年2月28日英特尔开发商论坛上首次展示了通用串口总线(USB)2.0,并表明高速USB2.0将得到广泛发展。英特尔台式机平台事业部高层管理人员还说,英特尔芯片将使高速USB2.0在2002年中获得广泛的发展。高速USB2.0接口提供了从Opteon＇sUSB2.0传递实时视频信号所必需的带宽,同时可让单人能够制作出具有电视广播质量的实时视频信号。为此USB2.0的推出使USB标准跨越了在速度上无法与IEEE1394相抗衡的尴尬现状后,同时具有了应用广泛和速度的优势。那么下一步USB与IEEE1394会怎样争夺市场?为什么两个标准都可以存在?谁将是速度提升后最终的受益者?先让我们从头了解一下USB和IEEE1394标准。
The Universal Serial Bus (USB) 2.0 was demonstrated for the first time at the Intel Developer Forum on February 28, 2002, and demonstrated that high-speed USB 2.0 will be widely developed. Intel’s desktop platform division executives also said that Intel chips will enable high-speed USB2.0 to be widely developed in mid-2002. The high-speed USB 2.0 interface provides the bandwidth necessary to deliver real-time video signals from Opteon’s USB 2.0, while allowing a single person to create real-time video signals with TV broadcast quality. For this reason, the introduction of USB 2.0 makes the USB standard cross the speedy situation that cannot compete with IEEE 1394. At the same time, it has the advantages of wide application and speed. Then how will USB and IEEE1394 compete for the market next? Why both standards can exist? Who will be the ultimate beneficiaries after speeding up? Let’s take a look at USB and IEEE 1394 standards from scratch.
