Local conference HD recording system and remote sharing
The recording of local conferences refers to the process of connecting to a video recorder through a camera installed in a conference room, a classroom or an auditorium, and connecting the video recorder to a monitor for video recording and playback. The cost of the local conference recording system is relatively low, and it is more convenient to use. Different from local videoconferencing, videoconferencing refers to the fact that the two or more conference sites are far from each other. Through videoconferencing endpoint devices, point-to-point or interactive video and voice interactions between conference sites can be realized. However, the cost of videoconferencing terminal devices is not limited. Relatively high. With the advent of the Internet+ era, in many areas when opening local conferences, not only local video recording and playback are required, but also units or individuals far away in the field can see and hear the conference live. The conference and realization of remote sharing are briefly explained as follows:
First, to achieve the local conference HD recording and remote sharing prerequisites:
1. Have a hard disk recorder that supports HD recording and has network capabilities.
Currently, there are many high-definition cameras with HDMI or SDI output interfaces on the market, and there are more DVRs with network functions. However, there are few types of recorders that actually support high-definition interface input and high-definition recording. Most of them are analog NVR network machines. Or AHD-type analog simulators that support HDMI, VGA or DVI, SDI input only WHD series HD recorders. Therefore, to implement HD recording and remote sharing for local conferences, a WHD HD recorder must be configured. WHD recorders support HDMI, VGA, HD-SDI HD camera input, according to the different input interfaces supported by many models, according to the conference room configuration of high-definition camera output interface and the number to choose which model WHD. For example, if the conference room has 4 HDMI output cameras, select WHD-04. If there are 2 HDMI cameras, select WHD-02. If there are two HDMI output cameras and two VGA output computers need to record at the same time, select the WHD-13 model. Currently, the HDD series supports up to 16 HD video cameras at the same time.
2. The conference room should have a relatively stable broadband network and configure the router.
Because it is the real-time transmission of high-definition audio and video, the audio and video fluency of remote sharing has a lot to do with the bandwidth of the local network and the network bandwidth of the remote sharing unit. The higher the network speed, the better the fluency.
3, HD video camera matching to achieve high-definition video, we must choose high-definition cameras, really achieve 1080P resolution HD video camera camera must have HDMI or SDI output interface. This HD camcorder already has several brands listed. However, to achieve ideal control management and convenient use, it is still necessary to choose the ideal model. According to the long-term use experience, the author feels that using the ChunYuan Liying CYC11 conference HD camera is good. Because this model uses SONY1/2.8 inch ProgressiveCMOS 2 million pixel lens, high video resolution, up to 1080p/60/50, while built-in high-speed all-round head, with HDMI, VGA output interface, the key is the machine The zoom function is powerful and supports 20x zoom. It can zoom in close to a resolution of one meter for a distance of 20 meters. Moreover, the machine can preset 10 fixed focus positions, and can be positioned by a key with a remote controller. It can be infinitely 355 degrees. The bit rotates continuously and the pitch range reaches 210 degrees.
4. Have a high-definition TV or monitor with HDMI or VGA input.
Second, the equipment connection and installation
1, the installation of the camera According to the size of the conference room, the scientific configuration of the location and the number of cameras. Generally, about 200 conference rooms are equipped with four cameras, and about 100 conference rooms have 2-3 cameras. There is a camera owner to shoot on the rostrum, and other cameras are responsible for the full picture of the conference room. CYC11 cameras can be placed on the cabinets and can also be fixed on the wall or ceiling installation. The installation location must have power outlets. After the cameras are installed, the HDMI HD cables must be connected and fixed in an orderly manner. It is necessary to measure the HD video from the camera to the WHD. The distance of the recorder. HDMI HD line single line effective distance of 20 meters, more than 20 meters, to configure the HDMI extension amplifier, the general configuration of 60 meters of effective signal amplifier can, I suggest the use of HDMI network video amplifier extender, launch and receive a set of prices less than 300 yuan, extension amplifiers also provide power outlets.
