According to the company, the release of SyncroStream means WorldCast can now offer the entire technology chain necessary for SFN deployment through its APT codecs, Ecreso FM transmitters, Audemat FMMC5 measurement gear and Kybio monitoring software.
Worldcast explains that SynchroStream technology and the “single pane of glass” approach can benefit broadcasters by simplifying the setup, configuration and maintenance of an SFN network. SynchroStream is compatible with baseband audio coding and the existing MPX/composite linear coding schemes and also the new non-destructive APTmpX composite algorithm, which is also part of the SR 4.0.
SynchroStream is integrated into the existing APT IP codec range and utilizes an externally supplied 10 MHz clock and the 1pps GPS signal as time reference. WorldCast adds that it offers an “a la carte” method to SynchroStream from the “single pane of glass” to just the APT codecs to be used as the transport to an OEM FM transmitter, also supporting SFN on a 10MHz input.
“BETA network deployments in New Zealand and the United States have verified bench test results, which calculated that the granularity offered in allowing fixed line adjustments down to an eighth of a microsecond (125 nanoseconds) would allow the highly accurate (<50 Meters) manipulation of the ‘mush zone’,” said WorldCast in a release.
“In the real world this means that engineers can push the almost non-existent mush zone away from populated areas or transport corridors. This manipulation translates to better coverage within the SFN FM area, consisting of main FM transmitter and FM Boosters, meaning potentially more listeners for your station,” it stated.
