In our elementary school we use our video distribution system as a closed circuit TV with only one channel that works through the entire 
Video Distribution System and GPB resources
school.  Several years ago, our system was much more efficient with the Teachers having the capability for starting their own videos from their classrooms.  I know from talking with some of the other specialists that they are in the same situation but the newer schools have been getting updated equipment and more video capabilities.  One school is even getting a green screen to use for their morning news cast.  We are on a list for updating but couldn't get a clear answer from the county when that date would be, just that we were on a list.  In the meantime teachers have taken upon themselves to use their technology carts to project and view more videos.
Right now we use our system for sharing the morning news and when teachers want to view a particular VHS/DVD for a lesson.  Right now I have a sign up sheet for videos and teachers are first come first serve for the one channel, otherwise they have to check out a rolling TV with VCR/DVD player.  I have found that with all the changes in the curriculum, teachers aren't viewing videos like they used to.  Teachers are finding other resources to use in their teaching.  One big resource that is used is the United Streaming option with GPB.  This site offers tons of videos, resources and plans for educators.  At the beginning of school I got a school pin number to use for setting up accounts in order to access the GPB site.  I love this site because it goes right along with the Common Core Standards and can be accessed directly by the teachers themselves.  If you haven't gotten the chance to check this site out, it is worth it and you won't be disappointed!  
I am looking forward to the future renovations and what they will do with the distribution system to make it more accessible for teachers and students.  I especially would love to be able to spotlight more student projects and how they are using technology to produce.
