The live streaming of the Hugo Awards ceremony was cut off just before Neil Gaiman's acceptance speech for the Doctor Who script, "The Doctor's Wife" when the copyright violation monitoring software running on all UStream feeds recognized the clips from the episode and decided to block the transmission.
This despite that showing such clips are within fair use and they had been provided by the studio specifically to be shown that way.
If only it had happened to the Oscars, that way this insidious threat would have come to the attention of the masses.
The reaction by Ustream is not to recognize that the concept of violation bots is fundamentally wrong, but to disable it temporarily "until we are able to recalibrate the settings so that we can better balance the needs of broadcasters, viewers, and copyright holders.".
