NAB Sneak Peek: DaySequerra Has HD Radio’s Time

TimeLock algorithm is designed to maintain HD Radio alignment

Having time-alignment problems with your HD Radio? Perhaps some of the products that DaySequerra has brought to the NAB Show can help.

The M4DDC (shown) is a diversity delay control that runs the company’s proprietary TimeLock algorithm to automatically maintain perfect time alignment of the HD Radio MPS and HD-1 audio streams, it says.

The M4DDC can email alerts for loss of TimeLock, Level-Lock (optional), program audio, carrier, or OFDM HD Radio Lock. There are five rear-panel alarm tallies. The unit is compatible with PPM codes, protecting them while rebuilding audio. Delay can be up to ±7 seconds.

An onboard Web server allows for remote operation and updating. A front-panel lock-out provides security.

DaySequerra’s M4.2S an analog AM/FM and HD Radio AM/FM tuner that can monitor HD Radio diversity delay with its proprietary TimeLock algorithm.

The M4.2S receives the off-air broadcast, measures the timing difference between the MPS and HD-1 streams. Out-of-tolerance conditions can be reported via email and via its built-in webserver using any browser on a network. The M4.2S can be flash-updated using its Ethernet port and has four additional rear panel alarm tallies.

The M2HDSP analog AM/FM modulation monitor can also monitor HD Radio diversity delay with its proprietary TimeLock algorithm. It receives the off-air broadcast, measures the timing difference between the MPS and HD-1 streams. Out-of-tolerance conditions can be reported via email and its built-in webserver. It can be flash-updated using its Ethernet port and has four additional rear panel alarm tallies. Its built-in webserver displays a broadcasts’ Artist Experience album art, station logo and advertisers’ branding.
