Yes its a pinger signal.
TO download the entire data of the black box would be a different problem because you would be talking about an enourmous amount of data that would take a long time to transmit, assuming that anyone was ready to hear it. But presumably if you can hear the pinger you can recover the black box, so relax and have a little patience. These things take time. Reconstructing maintence record of this aircraft to determine whether or not it was in compliance with all service bulletins will take quite some time... (Its much harder when you can't just look at theplane, and instead have to verify part numbers etc from a stack of papers as tall as the tail fin)
