What video server <br> <br> called network server is a video compression apparatus for processing video and audio data is embedded, which is compressed by the audio encoder, an input / output channels, network interfaces, audio interfaces, RS485 / RS232 serial interface, protocol interface, software interface and other components.
With the continuous development of audio and video coding technology and the development of broadband network technology, the realization of video transmission becomes easier and the cost is lower, so that the demand for video transmission is increasing. There are many network video server products on the market that meet the needs of network transmission, including video cabinets and video and audio servers. This article tries to analyze the video server from the aspects of the concept, composition, digital audio and video coding technology, network technology and characteristics of the network video server in a simple language so as to make it easier for everyone to understand and select the network video server.
The concept of the video server is what <br> <br> network video server is a dedicated device for audio and video data encoding process and complete the transmission network, enabling remote monitoring function. The video and audio server sets audio and video data to organize, summarize, edit, store, and store in one, and freely copies Blu-ray discs, DVDs, and CDs into complete data.

Audio and video compression encoder: As the amount of analog video data is very large, the amount of data after conversion through digital-to-analogue is also very large, so it is necessary to use mature coding technology to make the video data perform high compression ratio under the technical indicators that meet the requirements of network transmission. Coding to meet transmission requirements. Previous network video servers generally used M-JPEG and other encoders, users can not achieve a higher compression rate, suitable for a variety of different network environments, can only achieve the effect of a general network transmission effect by reducing the frame rate. All companies have already launched MPEG4 network video servers to meet the requirements of video network transmission.
Network Interface: Since the networking of previous analog products is mainly implemented through the establishment of expensive and independent optical fibers to realize network transmission, the Ethernet interface of the network video server can easily implement IP networking and achieve data transmission. The network video server mainly adopts protocols such as TCP/IP to realize network transmission of data such as audio and video data, control data, and status detection information.
Audio and video interface: Network video server with standard analog audio and video input interface, easy to monitor the video signal of each channel. NetVision uses Dynamic Stream Control technology to ensure real-time transmission of two-way audio. The video frame rate is automatically adjusted according to the bandwidth, and the network connection is automatically connected after the interruption.
RS422/RS485 serial interface: The network video server has RS422/RS485 serial communication interface, which can be connected to various peripherals such as PTZ, dome and other peripherals via communication lines.
The network video server can cooperate with the computer control software to realize the large-scale system networking program. Some manufacturers' network video servers provide an open SDK for users or third-party vendors to develop and construct new application methods.

PC Wire
PC wire is used in major construction projects as a means of increasing the strength of cast concrete components, ranging from railway track sleepers, ground stabilizing piles, floor beams and pipe systems. The process involves the continuous heating and stretching of a cold drawn high-carbon steel wire to produce a finished product with a much improved yield stress and greatly reduced load relaxation.
