What Is Inverse Multiplexing?

Inverse multiplexing refers to a multiplexing method that organizes high-speed digital signals for transmission in several low-speed channels. Inverse multiplexing uses demultiplexing and then multiplexing, which is different from the conventional way of multiplexing and demultiplexing.

Inverse multiplexing appeared in the 1990s, and its functions and

A basic application of the inverse multiplexer is to support broadband services such as video conferencing. For example, for a 1.5Mbit / s-based video conference, if you want to get high-quality, full-motion, long-term video, you must have a stable bandwidth. For a 15-minute meeting with a colleague, the only thing that needs to be resolved is pixelation or artificial motion. However, for a 2-hour meeting to discuss new advertising strategies, the sound quality and the reference object used by most users TV is important in parallel. If the company's practice is to hold video conferences twice a month, few users will be willing to pay 1.5Mbit / s to 2Mbit / s connection fees for 4 hours of video services per month. Instead, they are more willing to use their existing digital equipment to transmit the communication traffic, because the inverse multiplexer can do the same. ^[2]

With the inverse multiplexing technology, the inverse multiplexer can provide users with flexible bandwidth. In this way, even if the user does not order a dedicated line, the existing communication capacity can be allocated to implement broadband services. ^[2]
