Wen/Xu Jianlin In the field of real-time multimedia, real-time visual and perceptual display will have more extensive development space, while the basic core technology for real-time video transmission is the coding standard of H. In this paper, the author tries to solve the two problems of the core of the coding and decoding, one is the process of encoding and decoding, and the other is the structure of the code stream, hoping to help the people who

With the development of technology, the product needs to improve the data transmission speed. The data transmission mode of the IDE interface hard disk has undergone three different technological changes, from the initial Pio mode, to the DMA mode, and then to the ultra DMA mode. Pio ModeThe English spelling of PIO is "programming input/output model". Pio mode is a data exchange mode that reads and writes d

Sometimes in the backup or synchronization with a large number of files (such as a few GB or dozens of GB of database directory, log directory), the direct SCP takes longer, although the first compression and re-transmission can be decompressed, the amount of data transmitted is really reduced, but compression and decompression will also take a lot of time , the overall effect is not satisfactory, yesterday night whim, due to previous experience in st

The two remote transmission technologies have different advantages and disadvantages: fiber network topology is undoubtedly the first choice in terms of performance, but it is more economical to use IP addresses or the existing network topology, to make full use of the high-speed IP network and existing communication links, you must consider both fish and bear's paw.The communication link between the local and remote disaster recovery ends is an impor

I. Preface in the past 20 years, Internet, mobile communication and multimedia communication have achieved unprecedented development and great commercial success. The convergence of mobile communication and multimedia technology is accelerating. research results in network architecture, low-power integrated circuits, powerful digital signal processing chips, and efficient compression algorithms are emerging. Video Image Coding and transmission technol

After learning some basic FTP knowledge, Let's explain the FTP data transmission mode. This is also an important process to master this part of knowledge. I hope you can understand this knowledge clearly. Among many network applications, FTP File Transfer Protocol has a very important position. Software resources are a very important resource in the Internet, and most of the various software resources are stored on the FTP server. Like most Internet s

Wavelength Division Multiplexing Technology 1 Wavelength Division multiplexing Technology Wavelength Division Multiplexing (WDM) refers to the simultaneous transmission of two or more optical wavelength signals through different optical channels in the same optical fiber, known as the Optical Wave Division multiplexing technology. Wavelength Division multiplexing includes frequency division multiplexing and wavelength division multiplexing. There i

Source: Encrypted transmission of data--tea encryption and decryption algorithm implemented on single chip microcomputerHeroes in doing data transmission, have not considered the data encryption for transmission, if the serial or wireless data to be transmitted in the encryption, it is not to increase the security of communications. Commonly used encryption and d

From the first contact with the HTTP protocol, I do not know what is going on, forming a false view that the HTTP protocol is a pure ASCII character protocol, that is, in the HTTP stream is not see the binary stream of the 0x00 value. In fact, the answer is that the content in the HTTP protocol can be a pure binary stream. http://my.chinaunix.net/space.php?uid=22568683do=blogid=84701 The process of HTTP transmission of ASCII text content is believed

In today's network age, the development of the virus presents the following trends: Virus and Hacker program combination, worm more rampant, virus more destructive, the method of making virus more simple, the virus spreads faster, the transmission channel more, the virus infects the object to be more and more widespread. Therefore, a sound security system should include a comprehensive solution from desktop to server, from internal users to network bo

The driver example for USB ISO transmission in the WDK 7600.16385.1 is for USB2.0 and USB1.1, which is HS and FS. This example is not very special, but it is interesting to USB2.0 's ISO-transmitted data segmentation algorithm. According to MSDN reference article: http://msdn.microsoft.com/en-us/library/windows/hardware/hh406225.aspx USB2.0 ISO transmission needs to vary according to the interval value of

Although the hard disk has been very popular, but for many office workers, the amount of storage may not be very large, so relatively speaking, it seems to be a U disk used to compare the actual, but in the use of USB stick system, the small series has seen a lot of people complaining about the transmission speed of the U disk is too slow, this belongs to "mishap" is not so easy to solve, but not easy does not mean that can not be solved, below, small

, 407 us-> current_urb-> actual_length ); 408} If the result is successfully submitted, the returned result is 0. Act_len records the actual transfer length. However, simply looking at these two functions, we have to look at the context. In other words, we need to combine the context of the call of usb_stor_bulk_transfer_buf in usb_bulk_transport () to compare the parameters and real parameters, so that we can truly understand and open up this thick fog. Before carefully analyzing usb_stor_B

Article title: ADSL + MSTP build a comprehensive Metro transmission network. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. In the face of increasing diverse transmission business needs, it is important for communication operators to establish a

Chapter Content Transports (transmission) NIO (non-blocking io,new io), OIO (old io,blocking io), local (native), Embedded (embedded) Use-case (use case) APIs (interfaces) A very important work for network applications is data transfer. The process of data transfer varies depending on which vehicle is used, but the way it is transmitted is the same: it is transmitted in byte-code.Java Development Network Program data transfer

We need to know a lot about FTP. This includes its transmission mode. Here we will give a summary of the system. Let's take a look at all the FTP data transmission modes. FTP (file transfer html "target = _ blank> protocol) plays an important role in many network applications. Software resources are a very important resource in the Internet, and most of the various software resources are stored on the FTP s

This article illustrates the TCP transmission of Java implementation socket. Share to everyone for your reference. The specific analysis is as follows: Client sends data to server * TCP transmission, the process of client establishment.* 1, create the TCP client socket service. The socket object is used.* It is recommended that the object be clearly defined as soon as it is created. The host to connect to

SSH can transmit data through the technology of online packet encryption; Using SSH, you can encrypt all the data that is transmitted, even if someone intercepts the data and cannot get useful information. At the same time the data compression, greatly accelerated the speed of transmission. In short, through the use of SSH, you can ensure that data transmission is more secure and more efficient

Many people are concerned about WiFi wireless transmission speed, in addition to network bandwidth and hardware performance, the location of the router is also a very important factor, sometimes for the router to find a good home, do not spend a penny can improve WiFi wireless transmission rate. Carefully siting a good home for the router First, the location and placement of routers is the most basic (and

Dji Data Transmission considerations When using the DJI Mobile SDK and the DJI onboard SDK for data transmission, the demo from mobile device to onboard device was quickly implemented in DJI. But from onboard to mobile but tried many times can not be achieved, later, read a blogger's article, finally found the reason. reason: the transmission from onboard to mo
