Concern about video quality is to be expected, says Thompson, because companies want to make sure they get it right.
“Everybody wants to make sure that when they deploy these types of technologies that they have a high level of expectation from new users, of course, and they want to be able to meet that high level of expectation,” he says.
Thompson adds that videoconferencing quality standards are still in the development phase. Metrics like packet loss, latency and jitter, which are used to measure the quality of Voice over IP (VoIP) audio calls, are also applied to video. But video needs an additional metric, codec, which is short for “code-decode,” the process of coding a video transmission on the sending end and decoding it on the receiving end.
“Today there’s not a lot of great standards out there to define what is a good score for a video,” he says.
Adoption and concerns about cloud computing will be in the second installment of this series.
