ISMA Drives Testing of Emerging Streaming Media Technologies

Three standards organizations joined forces to conduct robust testing of emerging standards in streaming rich media, such as music and video, over the Internet. Engineering staff from companies in North America, Europe and Asia converged in New York this month to test their products and technologies.





The three organizations that participated:

  • ISMA (Internet Streaming Media Alliance)
  • IMTC (International Multimedia Telecommunications Consortium)
  • MPEGIF (MPEG Industry Forum)

    The Plugfest took place at IBM Research Labs in Hawthorne, New York, which was hosting the concurrent ISMA 15th Forum. Technologies of focus were:

  • AVC (Advanced Video Coding) file format testing
  • HE-AAC (High Efficiency Advanced Audio Coding) file format testing
  • AVC streaming
  • ISMACryp - an encryption and authentication framework for media streams
  • Closed Captioning - a framework for creating and delivering synchronized captions, subtitles, and audio descriptions with digital media content

    Hundreds of files were tested in a mixed environment of servers and clients from a variety of global manufacturers. More than 100 AVC files were tested including raw H.264, MP4, and 3GP file formats. Audio files available for testing included backward and non-backward signaling modes, mono, stereo, 5.0, and 5.1 formats. An MP4 File Validator was available for automated testing of AVC and HE-AAC hint tracks. Live encoding of closed captioning was tested successfully as was file encryption and streaming using IMSACryp.
