NASA-HDBK-2821, NASA TECHNICAL STANDARD: AUDIO AND VIDEO STANDARDS FOR INTERNET RESOURCES (08-FEB-2012)., The evolution of audio and video resources on the World Wide Web has grown beyond a fashionable trend and is fast becoming a primary means for communicating to a global audience. However, a result of this increasing success has led to such a wide range of competing codecs, media players, formats, wrappers, viewing devices and delivery options that accessing content has become increasingly confusing and can discourage even the most savvy web users. The National Aeronautic and Space Administration (NASA), a distinguished world class leader in Science, Engineering and Exploration has offered audio and video resources content on the internet for over a decade, though these offerings have suffered because of rapid growth of these various options and formats. Due to this perplexity, it has become a priority of the agency to establish an audio and video resources standard for use by the entire Agency to assure that every effort is made to reach the greatest possible audience with the simplest means available. This standard has been developed by the NASA Web Video Working Group and is approved and published by NASA for use by NASA Headquarters, NASA Centers and their subsidiary locations as well as NASA contractors where applicable to NASA contractual agreements. This standard provides a comprehensive guide for all audio and video resources produced by or for the agency, and also defines applicable requirements for accessibility as required by Federal law.
