TECHNOLOGY USE AND COMPONENTS OF VIDEO CONFERENCE
1. Technology used
System videoconferencing equipment is an electronic device systems (including hardware and software) using digital technology, image compression, and audio in real time (coder / decoder) audio St. Videoconferencing solutions based on IP technology with support for multiple protocols (H.320, H.323, SIP, SCCP) allows deploying the latest video conferencing, but still take advantage of the facility infrastructure available.
2. The composition
With a personal meeting, participants only need a computer equipped with software installed to perform the function HNTH terminal. The terminal should integrate or add peripherals such as cameras, microphones ... Allow meeting participants meeting point - point or multi-point as the basic equipment at the other common meeting room. The components required of individual meeting rooms including: software installed on computers (PC, Laptop) (Can be equipped with dedicated devices such as Webcams, microphones sound filter, the external display); The software can support the meeting point - the point, allowing connection to a maximum meeting 3 points without additional equipment in addition to multi-point management (MCU). Or possibly specialized equipment has been installed conferencing applications, integrated camera, dedicated microphone.
For each connection point to participate, need to equipped the following components to participate in the meeting (This is also required components fitted in meetings Point to Point):
CCTV: Autumn image signal
Micro: Record audio signal
Codec: Handling of receiving and transmitting encrypted audio signal and transmit images via
Display: Show contents of the meeting; Remote image, image data to be displayed.
Speaker: Plays audio signals meeting the proximal end; conditioner.
Connect to share pictures: Using more computers connect to share data on meetings
Depending on the infrastructure of the customer meeting that the number of audio equipment, the image will be optional on-demand meeting rooms area, the number of participants
The extension depending on demand
When customers wish to expand the number of connections in the meeting places and save the image; the audio conference can add the following components:
Storage: Store the details of the meeting
MCU- Connect multi-point: Use when clients need to connect multiple points during the meeting at the same time, supporting many advanced features. Allowing initialization, the meeting ended, customizable display layout, schedule meetings, supervision, quality management meetings ....
Model point-to-point connection
Model multi-point connections
Transmission line connection
Videoconferencing to operate effectively it is necessary to ensure bandwidth for all traffic with upload speeds with download speeds. At a small meeting room, same building large equipment where it can be used MCU via LAN connection speed of MCU should be guaranteed on 1:25 Mbps. At other positions will connect the center where the MCU (UVC) minimum requirements to 1:25 Mbps.cho sugars for HD quality TV.
Bandwidth connection to the maximum MCU when connected to the position is calculated by the score every point x bandwidth (1:25 Mbps). Speed above the speed alone applications for Point Endpoint and MCU; not shared with other applications.
When the operation signal generation video / audio needs to be open the application on the network traffic so that customers using lease line or WAN lines at each point is connected to a video conferencing system.
