Recently, new companies mainly work on static pages and write planning. The other is to learn about the communityserver project. It has been a month since we added up. On Saturday, I went to shangdiqi Street, a company. After talking with others, I found that this template class has been in use for a long time. When I came back, I thought I should add a feature that the template class always needed. Is to support information carriers. That is to say, in the custom tag parsing function, we can ob

I. Problem Description The existence of Network Address Translation and firewall (NAT/FW) blocks multiple multimedia communication protocols, including H.323, because the NAT device only translates the IP address/port of the message header, the message's IP header is inconsistent with the address/port information in the message's Net Load. As a result, the Message Receiver cannot correctly respond to the message, and the media channels of both parties cannot be properly established. In H.323 mul

Begin by checking if this is already installed by executing the following command:Rpm-q bridge-utilsIf the package is not yet installed, install it using yum:Su-Yum install bridge-utilsWith this package installed it is time to look at the current network configuration. the easiest way to do this is to run the ifconfig command. the following shows output from running ifconfig on a system on which KVM is installed, but on which a network bridge has yet to be configured:Eth0

Omit irrelevant content ...... The above is a very small part of the telephone communication protocol. The materials are too long. Do you think it is a bit dizzy? It doesn't matter. I will give you a simple picture to explain. Actually, there are many similarities between this stuff and Internet communication protocols. I wil

said to be "mature technology, start to try." Although precision marketing is hot now, it is still in its infancy. But why is there a precise marketing presence? I think it is the media changes, technological progress and consumption selectivity increase, and so on. In the past, the characteristics of the media is very single, is the carrier-only responsible for carrying content or advertising, and do not have the sales function. But as technology pr

With the increasing hardware performance of computers and internet devices and the explosive growth of Internet applications, the demand for Internet bandwidth is also higher. Even if the network only provides Internet access services for Intranet users, as long as it has a certain scale, it generally chooses multi-carrier links to achieve Internet access. The choice of Multi-link egress is to improve the overall bandwidth and network reliability of t

the requirement of 30 p for TV playback or 60 p for interlace broadcasting. This is the 3-2 drop-down frequency. What is 23.976p? There are two versions of 24 p for Program Production: 24 P for the film industry and 23.976 P for TV production.23.976p after 3-2 drop-down transformation, the field frequency is 59.94Hz. However, due to habits, 23.976p is often called "24p ". Why 23.976 P? The field or frame rate of a TV is generally the same as that of a local power grid. When a black/white TV is

the ideal (straight line) function-a measure of the Voltage Transmission Characteristics of input control. It represents the allowable nonlinear degree of frequency offset across the entire range in percentages.Note: The typical vcxo frequency voltage-controlled linearity is: ≤± 10%, ≤± 20%. The simple linear calculation method of vcxo frequency voltage control is as follows (when the frequency voltage control polarity is positive ):Frequency-controlled linearity = ± (fmax-fmin)/f0) × 100%Fmax:
