video conference

Videoconferencing is a technology that allows for the transmission of audio and video signals between two or more physically separate locations. This enables people to communicate as if they were in the same place, even when geographically distant.12

Key Aspects of Videoconferencing:

• Functionality: It involves sending both sounds and images, facilitating face-to-face interaction remotely.13
• Applications: Initially used in corporate boardrooms, it has expanded to telemedicine, distance education, political trials, and theatrical productions.1
• Historical Development: Early experiments began in the 1920s, with AT&T introducing the Picturephone in 1964, though it was not commercially successful. Modern videoconferencing relies on advancements in digital technology, codecs for compressing and decompressing data, and high-bandwidth internet connections.13
• Modern Usage: The COVID-19 pandemic significantly increased the reliance on videoconferencing for business and education, making tools like Zoom household names.1

Videoconferencing systems typically use cameras and microphones to capture signals, which are then converted to digital information by a codec. This compressed data is transmitted over networks and decompressed for the receiving end.1
