In the current computer application, the demand for fast parallel computing is extensive, summed up, there are mainly three types of application requirements:
Computationally intensive (computer-intensive) applications such as large-scale scientific project calculations and numerical simulations;
Data-intensive (data-intensive) applications such as digital libraries, data warehouses, data mining, and computational visualization;
Network-intensive (network-intensive) applications
In the current computer application, the demand for high-speed parallel computing is extensive, summed up, there are three types of application requirements:

At present, China's medical resources are limited, and distribution is not too balanced, encountered some difficult to cure the disease, the local county hospital often told patients: go to Beijing to treat it, if luck can also get a county doctor's recommendation letter, heal and return; if bad luck, the patient may die on the train leading to Beijing, die. Network hospitals and their derived telemedicine services can imp

This paper briefly introduces the key technologies and the current research situation of the content-based video analysis and retrieval, and briefly introduces the research hotspots in this area and the work to be done in the future.First, the issue of the proposed:The advent of the internet has brought great convenience to mankind, especially to realize the Internet after the sharing of resources, but in the face of this vast resources in the end what is the use of their own value? Since the 90

of CPU and GPU into APU, amd now has high hopes for a "two-architecture computing" Path in both x86 and arm architectures. Heterogeneous Computing, surround computing ...... AMD has created many new technical terms and brought people into a new era of computing.
"Surround computing is a special opportunity for us. It is related to IOT ." Mark papermaster explained, "it is a special opportunity to surround computing because the trend of device interconnection will continue. In addition to device

GPON protocol:In ITU, the uplink/downlink rate is increased to 2.5 Gb/s through the GPON passive architecture standard, and is encapsulated using the general frame-based protocol (green code, in this way, value-added services such as voice, data, video, e-commerce, distance education, and telemedicine are more effectively supported on the GPON platform.

[Zhongguancun online Camera channel original] at present, the camera market, the cheapest 30 pieces, expensive hundreds of pieces, and some even to more than one thousand pieces, the gap is so big, why? Is the seller shouting price over the sky? Or is there a big gap in costs? Or for other reasons? When you purchase a camera, you must first check the camera configuration. Just like installing a computer on your own. However, many users are confused about the choice of camera parameters. Today, l

I believe that in five years, we will surely lament our endurance. Second, the development trend of Internet applications. The penetration of RIA, especially P2P to traditional applications makes computing return to the client. In the future, our machine may not be a real personal com
all file formats suitable for streaming media technology.
Streaming Media Technology breaks through the network bandwidth limit on multimedia information transmission to a certain extent, therefore, apsaradb for memcache is widely used in many fields such as online live broadcasting, online advertising, on-demand video, distance education, telemedicine, video conferencing, enterprise training, and e-commerce.Streaming media-news media
For news media
requires a bandwidth of several k and allows users to use the Spot Video Conferencing System as long as they can access the Internet.
Performance indicators:
The video conferencing system provides all the source code in the system to facilitate secondary development and changes by developers.
The 100 m lan can support simultaneous viewing by tens of thousands of users. A single 4G dual-core server can support up to 10 thousand concurrent online users. A common 3 m adsl can support around 12-18
Streaming media refers to the media that transmits audio, video, and multimedia files over the network.
A typical feature of streaming media is to compress continuous audio and video information and place it on the network server. Users can download and watch the video, instead of waiting for the entire file to be downloaded. Because
Streaming Media Server
Streaming media technology is widely used in VOD, video conferencing, distance education, telemedicine
institutions, instant communication between teachers and students, emergencies in the field of public security emergency command, and instant communication of audio and video interactions between superiors and subordinates. Audio/video interaction platforms will be the focus of future demands. It is an essential core in the field of innovation!Instant messaging for video conferencingIt is no longer a new topic. In the past, the gradual development has been steadily and rapidly developing. With
and space, increases the learning opportunities, and is conducive to expanding the education scale, improving the teaching quality, and reducing the teaching cost. Learners can use a wide range of teaching resources to teach at their desired speed and in their own convenient time and place. At present, many universities have adopted streaming media technology to achieve distance education.
In addition, streaming media technology has been successfully applied in many aspects such as e-commerce,

But it itself does not have enough flow control function, when the same network port of the PVC at the same time data flow is very large, may cause congestion. Technical lack of support for SVC also makes it lose some of the advantages of the application, affecting the further promotion of the business.
