The specs for your computer to view the broadcast are minimal. You need a Windows or a Mac with either Windows Medial Player or RealONE player. Both are free. Media Player comes with Windows but, both programs can be downloaded for free.
You can test your settings by viewing a past broadcast. Here is the link to some programs that we are still streaming. If you can view these programs, you should have no problem viewing the live broadcast.
