Television interviews nowadays are worse than the radio interviews of my youth, with so much of the sound being garbled. It would seem sensible to switch to audio-only when bandwidth is limited, but this appears not to be the case.  Another solution might be to insert a delay for buffering, to cover rough patches.  Things do not have to be exactly synchronous -- people can get used to saying "over" at the end of a sentence and waiting a few seconds.The problem seems to occur with multiple software systems.  I wonder, can anyone on HN point to a technical treatment of this issue?
