audioDescription case:

   1. an audio component with an ISO_639_language_descriptor in the PMT
   with the audio_type field set to 0x03
   2. a supplementary_audio_descriptor with the editorial_classification
   field set to 0x01
   3. an ac-3_descriptor or an enhanced_ac-3_descriptor with a
   component_type field with the service_type flags set to Visually Impaired
