Between each pair of cities there is one transportation track or none. Now there are some cargo that should being delivered from the one city to another. The transportation fee consists of the parts:The cost of the transportation on the path between these cities, andA certain tax which

description which contains the RGB signal. There is also a standard for scart terminals that contain Y, C signals, equivalent to the S-terminal.However, in North America and in countries and regions where TV is NTSC, the RGB signals are connected separately with BNC plugs. In this state, the signal level of R, G, and B is 0.714V, which contains the base pulse. If the G signal is synchronized, the level of the sync pulse is 0.286V. about the YUVThere

Installation
The hardware required to run SyGate is the general configuration of a computer capable of running Windows 9X. However, in order to be able to travel online, the level of hardware is naturally higher.
The network can be connected using a NIC compatible with the NE2000 ISA or PCI bus. It can be connected using a HUB connection or a twisted pair connection. It can also be connected using a thin cable with a BNC connection 50Ω to connect var
I. router interface
A vro has powerful network connection and routing functions. It can be physically connected to a variety of different networks, which makes the router interface technology very complex, the more upscale a router has more interface types, because the more network types it can connect. Vro ports include LAN ports, WAN ports, and configuration ports.1. LAN interface
Common Ethernet interfaces include AUI, BNC and RJ-45 interfaces, as

Work notes: hardware-related knowledge
The maximum size of the standard video signal is 700mV, and the basic voltage is between 0.7-1 V. The camera output is basically a BNC connection tip: use A multimeter to test the two wires connected to the two ends. If you know the standard voltage, you 'd better test the standard voltage. Aviation plug: it is an electromechanical component that connects the electrical line. Therefore, the electrical parameters

CompositeVideo [RCA or BNC] (aka "Yellow-plug" video)
The old "Av" Standard connector. The common RCA connector is color-coded yellow for composite video.The term "Yellow-plug video" is recommended to help cut down on confusion between "composite" and "component" (which sound alike ).

new generation of cameras combined with traditional camera and network technology, it can transfer images across the network to the other side of the Earth . IP Network Camera is based on network transmission of digital equipment, network Camera in addition to the common composite video signal output interface BNC , there are network output interface . The different network protocols that support output can be broadly divided into two types:1. RTS
the most popular network adapters now. The so-called adaptive is to have automatic detection of network speed characteristics, if your current physical device is not able to transmit 100Mb, it will automatically drop to 10Mb.

The maximum transfer rate is 1000Mbps. Also is now said that the Gigabit network card, can be based on the line and physical equipment to automatically detect the speed of the network.

Do a wiring network engineering and wiring test, and now talk about wiring system training courses, contact with thousands of users, some feelings, written to peer experts advice.
Network Cabling (Network and cabling):
First contact with network engineering, there is no concept of wiring, to do a network engineering concept is to hold the hub, network card, network cable (possibly coaxial) and RJ-45 head (may be BNC head and matching), but also with
If only to connect two computers, then regardless of serial connection, port connection or the use of two network cards to achieve interconnection is possible. However, to connect more than 3 computers, you have to connect the computers together through the hub or switch (switch). Buying a hub or switch for a network of 3 machines seems less lucrative. If the use of coaxial cable connection of the total line network, although the problem can be solved, and the network is very simple, hardware co
