SynchroCast3™

Multiple Transmitter Simulcast System

SynchroCast3™ System
Intraplex® SynchroCast3™, the latest simulcasting system from Harris, provides a dynamic, scalable solution for single-frequency networks of overlapping transmitters. The SynchroCast3 modules work with the proven Intraplex T1/E1/IP multiplexers and the precision of GPS digital timing. This enables a network of transmitters to work together to increase coverage areas and reduce interference. The SynchroCast3 system will automatically adjust for any link delays that occur. Link delay changes can result from network rerouting, signal path fade and other network conditions. The delay received at the transmitter is continuously sampled. If a change in delay persists, SynchroCast3 will initiate a delay correction at the transmitters. Once the delay correction is started, the shift in delay time is done seamlessly, without interruption to system operation and at a controlled rate to prevent overshooting the desired delay.

System Compatibility
The SynchroCast3 system can be installed in Intraplex® STL HD, AudioLink PLUS™ and NetXpress™ systems and works with many Harris® Intraplex channel modules.

Product Details

Optimizes the Use of Available Frequencies
SynchroCast3 allows the use of a limited number of radio broadcast frequencies to cover a wider geographical area, often with the existing infrastructure. Turning a traditional radio transmitter network into a simulcast network can improve penetration in areas with marginal coverage. Medium and smaller transmitter systems can now realize the advantages of proven Intraplex SynchroCast® technology without the need to install a completely new transmission system.

Third-Generation Product Improves on Industry-Leading Performance
Synchrocast3 improves on earlier generations of the SynchroCast product with increased time sampling, new alert/alarm reporting features, simplified installation and management, and the ability to be integrated into existing SynchroCast installations. More efficient use of network bandwidth reduces timing overhead and allows addi-tional bandwidth to be allocated to audio and data transmission. Dynamic and hitless delay adjustments, reliable operation, and flexible implementations continue with this newest-generation product to provide the highest level of service possible.

Dramatically Improves Coverage Areas
Now, broadcasters can install a simulcast radio system on a single channel without having to install a completely new transmission system. The SynchroCast3 system makes new GPS-based timing technology available to older transmitter networks. It gives users easy control of the system functions critical to adjusting the coverage area to achieve desired performance. SynchroCast3 also provides reference signals to the transmitter station for precise control of channel frequencies. The system uses either T1, E1 or IP transmission lines, now readily available from Telco carriers or via private networks. These can be traditional land based, microwave, or fiber optic links. In fact, these systems can include a combination of public and private network links and still precisely control the necessary parameters to achieve peak simulcast performance.
