Rodney Grubbs, NASA Digital TV Program Manager, will conduct two

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.
