What is Video Conferencing

Video conferencing is a visual communication session between two or more users regardless of their location, featuring audio and video content transmission in real time.

For effective video conferencing, business companies or organizations need to set up a profiling conferencing software and hardware solutions for rooms, PCs, mobile devices, and browsers. Video conferencing consists of an endpoint (ranging from a simple PC to a telepresence system), video conferencing server (to run group videoconferencing), peripherals (webcam, microphone, speakerphone, headset, etc.) and software infrastructure (video processing, content transmission, integrations). Video conferencing is a modern high-tech communication tool for increasing efficiency for businesses, optimizing and accelerating decision-making processes, and cutting customer’s and company staff travel costs.

Video Conferencing Modes

There are two main video conferencing modes: point-to-point video calls and multipoint video conferencing. Point-to-point video call features a video session between two users, while multipoint or group video conferencing features video meetings with more than two users. Multipoint conferencing mode includes several subtypes depending on your needs, the number of participants and active speakers participating in the meeting.

Point-to-Point Video Call

Point-to-point video call is a video session involving two participants who can see and hear each other simultaneously. Both meeting participants are provided with various collaboration tools such as text messaging, file transfer, slide show, etc.

Symmetric Video Conference

Symmetric video conference is a full-duplex video session involving more than two participants who can see and hear each other simultaneously. Symmetric video conferencing is similar to a roundtable discussion where all participants have equal rights. This video conferencing mode is perfect if you need active involvement of all the speakers.

How to create group video conference

Voice-Activated Switching

With voice-activated switching, all participants can see and hear only the active speaker while he/she can see himself/herself or the previous speaker. The technology solution can be executed in various ways, but the idea behind VAS remains the same: video conferencing server monitors voice activity of the conference participants and immediately switches focus to the speaker. This mode features considerable disadvantages, e.g. false activation due to noise, coughing or mobile calls.

Role-Based Video Conference

Role-based video conference features two types of participants: active speakers and passive listeners. Every listener can become a speaker with the permission of the conference owner. The owner can add a new video conferencing participant, agree to give the floor to any listener or remove speaker’s rights immediately.

This way, the students easily focus on the learning process and don’t get distracted by other students, while the instructor is able to monitor them.

Streaming

Streaming is a conference mode which allows speaker to broadcast video to a wide audience without seeing or hearing the listeners. Other participants can see and hear only the speaker, while feedback is available via text chat.
