Blog Origin : The author of the whim, do collect 4 USB Camera Screen Small experiment, but encountered in the computer can only open at the same time at most 3 such headaches (personal analysis is the problem of the computer), so out of this way, in the client hanging 1, the server hangs 3 cameras, Using the socket for video transmission, this article is using the TCP protocol. The author's humble opinion, welcome to put forward criticism.
Android client uploads images to the server and uses XML to transmit base64-encoded ImagesI use the httpclient of Android to send post requests. I also want to use the post method to send data. However, the data is saved during base64 decoding on the server, I did not find the cause, so I did not write it out.
The reason why a POST request is sent is that the amount of data that can be transmitted at a time is large because the size of the image after base64 encoding is large. If you use get or
Let's turn on the Bluetooth feature in the following steps
1. On the phone I first found "application".2. Then in the open interface we click the "Set" button to enter.3. Then we click on the network connection in the image below to see a "Bluetooth" in the Open network.4. We first turn on the "Bluetooth" switch to the right and "OK".5. Well, if it turns green, it's open:
Step two, select the photos you want to transfer
1. We are also the same in the phone's "app" click on it.2. Then fin
1, we press the win+r on the keyboard, and then enter the Fsquirt in the operation; The effect is shown in the following illustration
2, then in the open access after we click on the Bluetooth file to receive and send the option to click "Send Files" or "Receive files" can be set up Bluetooth transmission files;
3, select the equipment to be sent;
4, then select the file, click the "Browse" button to select the file to upload an
Streaming Transmission is widely defined. It is a general term for the technology that transfers media (such as videos and audios) over the network. Its specific meaning is to transmit video programs to PCs over the Internet. There are two methods to implement stream transmission: realtime streaming and progressive streaming ).

Currently, audio/video (A/V) and other multimedia informati
核心提示：-->With the development of the IP network to the multi-service network, especially the development of VoIP in recent years, it is inevitable to transmit signaling messages in the IP network. But in the IP network cannot provide high-quality transmission services like mtp3 and ATM, so the ITU-T proposed an improved version of sscop-sscopmce in Multi-link and non-connection environment ), it is used to transmit signaling messages in an IP-bas
Currently, three most popular IP transmission technologies are available: IP over ATM, IP over SDH, and IP over WDM. All three IP transfer technologies will play their own roles in different periods of telecommunication network development and different parts of the network. The three will coexist and complement each other. However, from a future-oriented perspective, IP over WDM will be the most vital technology, and its huge bandwidth potential matc
MIMO technology can greatly improve the coverage range and transmission rate of WLAN.
When multimedia applications with low latency and high bandwidth requirements, such as home broadband network connections and real-time HDTV wireless communication, and applications with scattered and shared content for entertainment devices become more and more common, wireless communication technology is also required to improve its efficiency under the condition o
Transferred from: http://blog.csdn.net/hguisu/article/details/7418087Streaming is defined widely, and now mainly refers to the technology that transmits media (such as video, audio) over the network. Its specific meaning is the transmission of film and television programs to the PC via the Internet. There are two ways to implement streaming: Live streaming (Realtime streaming) and sequential streaming (progressive streaming). (Baidu Encyclopedia)The
In some previous articles, data transmission between the upper layer and the middle layer is involved. In short, the use of parameters and returned values. This is because the most important thing to do in the middle layer is data transmission and conversion. Next we will introduce this knowledge.Data transmission can be divided into
By default, WCF uses the cache transmission mode, but this will occupy valuable memory resources of the server. The more connections there are, the more memory occupied. When big data, especially large files, is transmitted, memory will consume light. Some people have provided a big data transmission solution in WCF, but it is still in cache mode, which is inconvenient to manage and cannot be used.

Ultra-smart Android data transmission method and android Data Transmission
In Android, data transmission between activities is somewhat complicated. For example, when a complex object is passed through Intent and Bundle, it must be a class that implements the Serializable interface, this makes data transmission between
Character encoding system of MySQL (II)-Data Transmission Encoding, mysql Data TransmissionThe character encoding system of MySQL can be divided into two parts: one is about how to manage the encoding of character data when the database server stores data tables, and the other is about how to encode the data transmitted between the client and the database server. MySQL character encoding system (1) -- Data Storage encoding discusses data storage encod

Fragment is used in development more and more times, and many small projects are directly using Fragment as the carrier of Activity to switch pages. During development, the most important issue of page switching is data transmission. Today, we will focus on the Transmi
WCF uses messages as the only means of communication. It supports different Message Exchange modes (MEP: Message Exchange Pattern). The following are typical MEP types: one-Way, Request/Reply, and Duplex. The message is sent to the transport layer by the channel layer of WCF and sent to the destination through the corresponding transmission protocol. For TCP, it can provide a duplex channel, so it can provide native support for the above three MEP pro
In the process of network communication, both parties need to exchange data, which requires high collaboration. In order to correctly interpret the signal, the receiver must know exactly when the signal should be received and processed, so timing is crucial. In computer networks, timing is called bit synchronization. Synchronization requires the receiver to receive data according to the start time, end time, and speed of each bit sent by the sender. Otherwise, an error occurs. Usually synchronou
Network transmission protocol and http protocol, transmission http protocolOverview: it refers to the constraints and specifications for communication between the server and the client. The data interaction between the client and the server is not disorganized and must follow (based on) certain specifications.

In section c #, we discussed the reliable transmission of udp packets (packet group transmission). However, the problem with the previous program is that the data is relatively large, A Message class has 2048B after serialization, and the actual data volume is only 50B, which indicates that the data is very effective. In this way, when too many packets are transmitted, the efficiency will be greatly reduced
