What’s the leading AV transmission technologies?

Table of Contents

Audiovisual over Internet Protocol (AV over IP) is an Internet Protocol-based audio and video transmission technology that transmits audio and video data over standard networks! AV over IP products has seen triple-digit growth in the past three years and will grow at a compound annual growth rate of 60% in the next five years.

Traditional A/V vs AV over IP

AV over IP is a game between image quality, bandwidth, and latency in specific applications. The AV industry has found the next best way to transmit audio and video signals, with IP providing a standardized architecture. But today, the way it is transmitted on the architecture no longer meets the needs of various customers, and we need to determine what image quality, bandwidth, and latency to allow based on the application. And because of this, in the face of various audio and video transmission protocols and trends, we need to distinguish precisely what is appropriate for the project’s needs!
