When thinking about video conferencing, most people call to mind common face-to-face video applications used for business meetings like Microsoft Teams, Zoom, or Google Meet. Yet video conferencing encompasses many other fields and usages.

With the global video conferencing market expected to double to 19+ billion in the coming years, let’s examine this important technology. This article will go over what is video conferencing, how it’s used and the benefits and challenges that come along with it.

Definition

Video conferencing, sometimes referred to as a virtual meeting, online meeting or web conferencing, is the real-time transmission of video and audio data over the internet or other communication network. This allows participants no matter where they are in the world to see, hear and talk to each other.

Video conferencing typically requires hardware such as cameras, microphones, and speakers provided on most basic PCs. It also requires video conferencing software platforms such as Microsoft Teams, Zoom, or Google Meet.

Basic History and Evolution

There were many attempts to bring video conferencing to life throughout the 20th century but most of those early technologies fell flat. It wasn’t until the 1990s, well into the age of home PCs, that video conferencing software really began to take hold.

The 1990s saw the first software, CU-SeeMe, which was video-only and in 16-bit grayscale. This was soon followed by instant messaging apps (AIM, MSN) and industry-specific video conferencing systems (NetMeeting, VRVS).

It wasn’t until the late 2000s with the widespread use of smartphones and 3G/4G technology, where Skype and other players made video conferencing popular for both business and personal communication.

How Video Conferencing Works

Video conferencing relies on a combination of basic technology and equipment to facilitate real-time communication between participants.

Having good quality video conferencing relies heavily on an internet connection with adequate bandwidth and low latency. In a traditional setup, this means two people with their internet-connected devices use an Internet Protocol (IP) to transmit data to one another. Codecs are used to compress the data in deliverable packets, allowing the two participants to chat in real-time.

The hardware setup typically includes high-definition cameras capable of capturing video at resolutions of 720p or higher. Microphones often include noise-cancellation features, while speakers or high-quality headsets provide clear sound output without echo or feedback.

Types of Video Conferencing

One-on-one meetings

These meetings involve two participants or devices that communicate directly with each other. They are commonly used for informal chatting, job interviews or personal consultations.

Group meetings

Group meetings include multiple participants from various locations that need to collaborate in real-time. Most international offices or organizations rely on this type of communication.

Webinars and large-scale conferences

These are virtual events where a presenter or panel communicates with a large audience. The communication is often one-way but can sometimes include interactive Q&A sessions and larger town-hall discussions.

Hybrid meetings

Since the pandemic, hybrid meetings are commonplace, combining both in-person attendance with virtual participation. This enables more flexibility and inclusivity for participants depending on their location or other commitments.

Uses of Video Conferencing

Business and Corporate Sectors

For most companies, video conferencing is used for meetings, client interactions, interviews, and webinars. For example, a project manager in New York might schedule a video conference with team members from Tokyo to go over project updates, share their screens to present documents, and converse as if everyone were in the same room.

Education and Remote Learning

Virtual classrooms are more and more widespread, allowing students and teachers to conduct live lectures and engage in interactive discussions. For instance, a professor might use Zoom to deliver a lecture for an online course. During the session, they can present slides, use a virtual whiteboard, and allow students to ask questions in real-time.

Healthcare and Telemedicine

Healthcare providers can use video conferencing to conduct remote consultations and to evaluate and monitor patients. For example, a patient in a remote area can schedule a video appointment with their doctor, who can visually assess the patient's condition, display lab results like x-rays, and even guide the patient through self-examinations.

Social and Personal Use

Individuals nowadays connect with family and friends using video conferencing and can maintain relationships over long distances. An example might be a student studying abroad who uses FaceTime or other video chat to keep in touch with their friends and family back home.

Benefits of Video Conferencing

Convenience and Accessibility

Nowadays, colleagues scattered around the world can discuss pressing issues face-to-face. Video conferencing enables participants to attend meetings from any location with an internet connection, removing the need for travel and allowing for more flexible scheduling.

Cost-effectiveness

Travel costs, hotel bookings and renting venues for conferences can be large line items for companies trying to meet. Using video conferencing as a solution reduces such expenses, making it a more economical option for companies and individuals.

Increased Productivity and Collaboration

Gone are the days when faxing or sending important documents via courier would extend a project’s timeline and prolong decisions. Video conferencing facilitates efficient project management and faster decision making through its enhanced collaboration and real-time communication and information sharing.

Environmental Impact

By reducing the carbon footprint associated with travel and contributing to lower greenhouse gas emissions, video conferencing has a positive environmental impact and can be a greener option for some businesses.

Challenges of Video Conferencing

With all the benefits of video conferencing technology, comes some drawbacks as well.

Technical Issues

Meetings where participants’ video drops out, intermittent sound or audio echos can lead to lots of frustration and misunderstandings. Online video sessions can be disrupted by unstable internet connections and poor audio and video quality, highlighting the need for robust technology.

Security and privacy concerns

During the early phase of Covid, many Zoom meetings were upended by an uninvited hacker who disrupted the call. The potential for unauthorized access, data breaches, and eavesdropping during video conferences requires robust encryption and security measures.

Digital Divide and Accessibility Issues

There are still many people around the world who have limited access to high-speed internet or necessary devices, making it challenging for them to participate effectively in video conferences. Upgrading global infrastructure or investing in portable solutions can greatly improve this situation.

Online Miscommunications

Some misunderstandings are not necessarily caused by technical issues, but more from the limited view of people on screen. This highlights how understanding body language and facial expressions can avoid these kinds of issues.

The Future of Video Conferencing

Video conferencing in the years to come will likely be an even more entrenched part of our daily lives. The increased integration with artificial intelligence will have a large impact, enhancing features like real-time language translation, automated meeting summaries, and smart scheduling.

In addition, the integration of video conferencing software with project management tools and virtual collaboration platforms will streamline workflows and create more productive meetings.

The Big Picture for Video Conferencing

The road to seamless communication via video conferencing hasn’t been smooth and straightforward. Yet with the rise of this groundbreaking technology over the past decades, and its technical benefits becoming more and more widely adopted by businesses and consumers alike, video conferencing is set to become a global standard for daily life.
