NASA Educational TV Audio
Unlike most televisions broadcasts, audio is included with NASA Educational TV video only when there is something interesting to say or hear. Because of that, periods without audio are normal.

Broadband Internet Connection Required
NASA Educational TV video data is streamed at 130 KBits per second. The associated audio data is streamed at 16 KBits per second. You therefore must have at least a 146 KBits per second Internet connection to watch and listen to NASA TV. However, your connection should have higher capacity than that for good results, because additional data normally will be transferred between the Internet and your computer for other purposes while your are watching and because it will not be possible to "catch-up" and recover from temporary Internet slowdowns or interruptions using an Internet connection that meets only the minimum bandwidth requirement. 256 KB is a realistic minimum Internet connection bandwidth for good results.
