In 2007, the Isis Group introduced a new Soundpals product, the ADLY-4: http://cdn-docs.av-iq.com/other/ACF3BC.pdf This product performs substantially the same functions that SyncPal does, except it works with digital audio that is separate from its associated digital video.
The Isis Group declared bankruptcy in 2014, and shortly thereafter, a startup company, RJM and Associates, resumed manufacturing some of the products (including Soundpals) that had previously been offered by the Isis Group.
RJM and Associates was acquired by Grid Petroleum in 2016, and the company was renamed Simlatus.
SyncPal is essentially a Soundpals ADLY-4 with additional circuitry that separates the digital audio from its associated digital video so that the audio can be delayed while the video remains undelayed.
If you compare the front panel of the SyncPal product, as shown in the SyncPal data sheet that is on the Simlatus website: http://simlatus.com/product/syncpal/ it is almost identical to the front panel of the ADLY-4 that is shown in the above-referenced ADLY-4 data sheet.
The bottom line: SyncPal is NOT a groundbreaking new product. At best, it's old wine in a new bottle.
