Online meeting takes place between 2 different offices called Point - to - Point or from 2 offices or more called Multi - Point, with the number of meeting rooms can be from 10 to 20 people/one meeting room.

Encoding standard: H.264 protocol (several versions available)
Communication standard: Standard H.323 protocol for video conferencing devices to connect with each other easily (software online video conferencing is difficult to connect to each other)
Content presentation standard: The H.239 protocol is used to project content on the screen in cases where presentations, training, etc.
Audio standards: G.711A, G.711U, G.722, G.722.1 (Siren 7), iLBC, Speex Wide… and some other standards
The basic video conferencing system has a Camera, a Microphone and a Codec. The image from the Camera and the sound from the Microphone will be converted to digital format and transmitted to the receiving location through a decoder, also known as a "codec head". At that receiving location, there will be another "codec head" that receives the signal, then decodes and outputs the image and sound to the screen and speaker, and the image and sound at the receiving location will be sent. return to the original position.
The solution works based on IP technology with support for multiple protocols (H.320, H.323, SIP, SCCP) allowing advanced online conferencing systems to be deployed while still taking advantage of the infrastructure. available.
