SynchroStream is APT's new technology for time-synchronous IP transmission and playout of audio content.
Content, such as radio programs broadcast with synchronized transmitters (SFN), be it analog (FM) or digital (DAB+), or multiple audio channels building a surround sound image which must be synchronized with high precision. APT SynchroStream is a professional solution for synchronized audio transmission.
APT's SynchroStream is the must-have solution for locking content to time over IP transmissions.
Broadcasting networks or surround sound transmissions benefit from the high precision of SynchroStream.The user defines the latency of a transmission, only once, and SynchroStream presents distributed contents at the exact same time.
Synchrostream is designed to dramatically reduce the impact of the uncertainties of an analog single frequency network.
The key to the optimal possible synchronization of modulated FM carriers is the smallest possible granularity of time shifts. With 125 nanosecond steps, SynchroStream offers an unprecedented level of granularity of modulation shifting. Disturbed interference zones in the propagation area can be shifted by distances of less than 50 meters.
SynchroStream is adjusted and optimized in just two steps.
As the user you define the desired target latency. This is done once in the studio on the content encoder. This, dynamically eliminates all deviations of the IP network. Afterwards the interference zones are optimized with the high-precision fine tuning at the transmitter. Thus, all carriers are in correct time relation to each other. The external GPS clocking locks all carriers and modulation feeds and ensures a stable, homogeneous RF field.
WorldCast Systems, with its complete broadcast network supply chain, offers all the building blocks for your most optimized
analog single frequency network.
“APT SynchroStream together with digital or analog composite/MPX transmissions, APT SureStream and Ecreso's optimally adapted FM transmitters are the components from a single supplier to build your most optimized analog SFN.
With APTmpX and SureStream you save on costly dedicated networks, with SynchroStream you expand your footprint and with Ecreso's FM transmitter you get the most energy efficient products on the market”.
