Description

GIBM-2000 is 2 IP HD streams over a single QAM Converting of IP network input signal into 1 QAM modulated J.83B channels.

An IP to QAM TransModulator is a specialized networking device that converts IP (Internet Protocol) - based digital signals into QAM (Quadrature Amplitude Modulation) modulated RF (Radio Frequency) signals, enabling the delivery of IP - based content over traditional coaxial cable networks.

Smart Campus Television System

In schools, IPQAM is primarily used for the efficient and stable distribution of video content, particularly suited for large-scale, concurrent access scenarios. It seamlessly combines the flexibility of modern IP networks with the stability and high-bandwidth characteristics of traditional coaxial cable infrastructure.

2 IP HD Streams Over A Single QAM

Specific Applications and Advantages in Two Scenarios

The IP to QAM TransModulator (commonly known as IPQAM or EQAM) finds application in settings such as shopping malls and meeting rooms. Its core function is to bridge the gap between modern IP-based streaming media and traditional radio frequency (RF) cable television networks. This enables the transmission of high-definition digital content without the need to replace existing terminal display equipment.

Shopping Malls / Commercial Real Estate

Typical Application Solution: Convert promotional advertisements, navigation information, and live program streams from the IP network into QAM RF signals, and distribute them via the existing coaxial cable system to televisions on each floor and in various stores.

Utilize Existing Cabling: Eliminates the need for rewiring by directly leveraging the widely deployed coaxial cable network, significantly reducing retrofitting costs and project complexity.
Centralized and Stable Distribution: Enables unified, stable, and high-quality broadcast-style distribution of programs from a central equipment room to hundreds or thousands of TV terminals, resulting in high management efficiency.
Protect Investment: Allows a large number of standard TVs or professional display devices in the mall that only support RF input to receive high-definition IP source content, thereby extending the equipment lifespan.

Conference Rooms / Video Conferencing

Hybrid Network Video Conference Downstream Transmission: In a conference system based on "IP+HFC" architecture, the IPQAM is responsible for modulating the server-side conference audio and video streams into RF signals, which are then transmitted downstream via the cable television network to terminal devices in each conference room.

Guarantee Critical Service Quality: The HFC network provides an independent, stable, and high-bandwidth broadcast channel for conference video downstream transmission. This avoids bandwidth contention with the office IP network, effectively preventing lag and packet loss, thereby ensuring conference quality.
Network Separation and Optimization: Achieves separation between audio/video downstream (via HFC) and control signaling/data upstream (via IP). This optimizes the network traffic structure and enhances the overall reliability and scalability of the system.
