Redundant PSU option for TIGER E3 and TIGER E5
The TigerSync Streamer solution by AxelTech offers a way to distribute audio to FM transmitters via web technologies using IceCast, a reliable and flexible protocol.
IceCast can handle thousands of connections and allows up to 15,000 users to listen without interruptions when the audio is uploaded to a cloud server. This protocol is unsuitable for traditional broadcasting as it is not synchronous and can result in a 1 to 5-second difference for users listening to the same radio broadcast. For instance, when the FM Tuner is equipped with automatic frequency control (RDS-AF) while driving, the seamless transition between the transmitters is imperative for ensuring an uninterrupted listening experience for the user.
AxelTech’s R&D efforts have been focused on ensuring that this technology is compatible with broadcasting needs. With the TigerSync Streamer option, a Tiger E5 Encoder serves as the network’s hub, handling the encoding process and transmitting the signal to an IceCast server. This can be the Tiger‘s internal IceCast server, with a limited number of reception points (up to 15) due to the Tiger‘s resource constraints, or an IceCast server set up on a Linux cloud server.
With TigerSync Streamer we have implemented a sophisticated method for synchronizing audio using inaudible timestamp codes. These codes are transmitted through the Opus codec at rates ranging between 32Kbits/sec to 510 Kbits/sec (or MP3 192kbits-320kbits/sec) and then distributed via an IceCast Server. On the receiving end, the Tiger devices capture the IceCast stream and timestamp data, ensuring precise synchronization for audio playback. As a result of this synchronization approach, there is a consistent delay lasting anywhere from 1.0 to 10 seconds, with the optimal latency falling within the range of 2 to 3 seconds. This fixed audio latency remains uniform across all decoding Tiger units in comparison to the encoding units, resulting in a reception delay. However, TigerSync Streamer guarantees that all decoders maintain synchronization with an impressive accuracy of a few milliseconds.
In the initial stages of the project, the target synchronization between decoded audio over the network was set at 30 ms. However, the achieved result surpassed expectations, with the delay being below 5 ms. While the system was not designed as an isofrequency, it effectively ensures the alignment of all transmitters and facilitates imperceptible transmitter changes.
TigerSync Streamer, designed to provide a backup feed to transmitters, has exceeded expectations by proving itself in the field as a technology capable of powering the distribution network through a solid, precise, and low-cost infrastructure.
