videótelefonálást

Videótelefonálás, also known as video calling or videoconferencing, is a telecommunications technology that allows two or more participants to communicate in real-time via a live audiovisual connection. Unlike traditional phone calls which rely solely on audio, videótelefonálás incorporates video, enabling participants to see each other while they speak. This visual element enhances the sense of presence and can improve understanding and rapport.

The technology behind videótelefonálás typically involves a camera, a microphone, a speaker, and a display device, all connected to a network, usually the internet. Data from the camera and microphone is encoded, transmitted over the network, decoded, and then displayed on the screen and played through the speakers of the receiving device. Various software applications and hardware devices support videótelefonálás, ranging from dedicated videoconferencing systems used in business settings to mobile apps and web-based services accessible on smartphones, tablets, and computers.

Videótelefonálás has become increasingly prevalent for both personal and professional use. For individuals, it facilitates staying connected with friends and family across distances, offering a more personal interaction than text or voice calls alone. In business, it is widely used for meetings, remote collaboration, training, and client consultations, reducing the need for travel and saving time and resources. The quality and accessibility of videótelefonálás have improved significantly with advancements in internet speeds and compression technologies.
