Rodney Grubbs, NASA Digital TV Program Manager, will conduct two teleconferences for broadcast, cable and satellite technicians about NASA Television’s upcoming conversion. Fred Brown, Executive Producer of NASA Television, will also be available for questions.

The two teleconferences are scheduled for Thursday, May 5, at 10 a.m. EDT and 1 p.m. EDT. Technicians and engineers with organizations that are frequent users of NASA Television and its video products are urged to call in.

NASA TV’s digital conversion from a single analog channel to multiple digital streams is slated for early to mid-May. The current analog signal will be provided through the end of June to allow for a smooth transition.

Grubbs, of NASA’s Marshall Space Flight Center in Huntsville, Alabama, has headed the agency’s television digital-conversion effort since it was initiated in 1997.
