Broadcast Positioning System Deployment in a Single Frequency Network

Sunday, April 19 | 11 – 11:20 p.m.

Broadcast Engineering and IT Conference

The Broadcast Positioning System (BPS) encounters complications when utilized in a Single Frequency Network (SFN) environment, as each node of the SFN must transmit the time and location data. While in a traditional MFN setup, this would not present an issue, the SFN presents a greater challenge, as the nodes all share the same frequency, and so can potentially interfere with each other. Because BPS is designed to be as receivable as possible, it is difficult to isolate these unique transmissions in the same manner as LDM for local content insertion, and so an alternative approach must be utilized. This paper outlines the background of these issues, describes a solution to resolve them, and provides the results of both real world and lab tests for a multi-node SFN with BPS enabled.
