'Knowledge Is Power' Is True Now More Than Ever

摘要

I first heard the saying "nothing is more permanent than change" when I was a boy, (60 or so years ago). It didn't really hit home then, but certainly does now in the second decade of the 21st century, especially in the field of broadcasting. There have been lots of changes since I first got involved in broadcast engineering. This was driven home in a big way recently when I audited a day-long course on IP-television offered by the IEEE's Broadcast Technology Society and taught by Wes Simpson (who also pens the Video Networking column for sister publication TV Technology). The class-"IP Video for Broadcast Engineers"-provided a detailed overview of the melding of the video and computer worlds, and covered such things as data transport, packet addressing, encapsulation, video streaming, digital rights management, content encryption, video "players," and much, much more (remember, this was a day-long exposure to the realm of IP video).
