Abstract: In this paper, a common real-time video transmission solution is proposed for different local networks. Based on the use of DivX codec, the idea of compressing, organizing frames, sending and receiving, and extracting the entire process is proposed. The specific implementation scheme and the core of VC ++ are as follows:Source codeAnd transmission control policies effectively ensure high-quality r

Html5 postMessage solution for cross-origin and cross-window message transmission, html5postmessage
There are also several common problems about message passing during web development in addition to passing values between the client and server.
1. data transmission between the page and its new window
2. message transmission between multiple windows
3. webpage and
Program requirements:
Programs are divided into server programs and client programs. The client initiates a request for a specified file and transmits the file to the client.
One server supports communication between multiple clients.
Data packets must have a verification mechanism.
There is a packet loss retransmission mechanism.
Supports resumable data transfer.
Can handle various exceptions normally.

1.1JrtplibLibrary Introduction
The system uses the open-source database jrtplib to develop the RTP transmission module. Jrtplib is a fully open-source RTP Library developed by EDM (expertise centre for digital media) of Hasselt University in Belgium and implemented in C ++, currently, it can run on Windows, Linux, F
In recent years, network operators have been heavily dependent on ROADM-based optical transmission equipment, using a fixed point-to-point WDN connection, using 10g wavelength in the entire metropolitan area network and wide area network convergence and transmission client services. If these networks are well planned, the existing spectra can be used reasonably and effectively. Typically, a tran0000der tran
Control CHannel: the control channel is used to communicate with the FTP server. The control channel is used to connect to FTP and send FTP commands.
Data Channel: data channel is a channel for file transfer or list with the FTP server.
You may ask why the FTP protocol requires two channels? Let me give you a simple example. When we use an FTP client such as ftprush to download FTP files, several directories and files are usually added to the queue window. When the download starts, how do I know

Program Output to other languages is one of the favorites of programmers. on the Web, we have
Two different programming environments: the client (browser) and the server, according to the HTTP Protocol definition,
We can write the program on the client to output the server programs in other languages.
The client language and JavaScript are output as the client. In this question, we will show you how to use
This solution stores data on the client and
The minimum data
In the use of the Internet, the most basic protocol stack is the TCP/IP protocol stack. The basic protocols are TCP transmission control protocol and IP Internet protocol. Next, we will introduce the concept and basic structure of the two parties, as well as their functions.

Remember a few years ago, see the "Environmental protection industry standards of the People's Republic of China (hj/t 212-2005): The source of online automatic monitoring (monitoring) system data transmission standards" this agreement, at that time looked at the head is big, finally did not start to design support him. Until recently, the customer said: you VOC instrument good ah, if you can support the HJ212 tra

With the continuous development of science and technology, mechanical Transmission control devices and mechanical equipment has become a closely related whole. The main task of this course is to make students understand the general knowledge of Motor drive control, master the
Two data transmission mechanisms are used in raknet. The latest UDT is used as the transmission control layer.
The following is a new transmission control mechanism.
In raknet, you can use # DEFINE _ use_raknet_flow_control to determine whether to use the old transmission protocol or the new protocol.

In enterprise-level development, relational databases are designed for interface transmission. This article takes oracle database as an example to discuss some design ideas about using databases for intermediate table data transmission during enterprise-level development.

connection is established, and there is no need to establish a connection every time and then interrupt.The advantage of this is that the server side of the load, reduce the cost of the part of the time, so that the HTTP request and response to the end of the faster, the corresponding, the Web page display speed is relatively improved.3) PipelineIf an HTTP request requests a large number of images and other large files, what about the other HTTP requests?Now, the advent of pipeline technology m
In the next few years, carriers will use SDN technology to enable their man and wan to carry cloud services. Therefore, they need a multi-layer SDN architecture to optimize the routing network and transmission capabilities, this increases the flexibility, scalability, and efficiency of man and wan.

Point of view 1:
In the construction of 3G mobile transmission network, a simple idea is to build a set of independent ATM network for UTRAN, but ATM switching equipment is more expensive, and as a basic network, practice proves that it is not the best solution for other business. In addition, ATM has the problem of automatic configuration and recovery time of the whole network connection in the use of fiber network, and it can't meet the requirement
Video conferencingIt is mainly used to develop software for transmitting audio and video data. During these development processes, the most core module is the transmission module. The performance of the transmission module directly affects the final quality of video conferencing, therefore, the selection of transmission modules is particularly important in video
