The impact of more video devices in more places is the consumption of more bandwidth than ever before, which will transform networking. And more processing and storage will be required than ever before, which will transform IT, including cloud computing.
Today’s HDTV streams need somewhere between 4 and 7 megabits per second. 4K or, in a few years, Ultra-HDTV video streams will need tens of megabits per second, just for one channel. Increase that further for 60 frames per second, finer gradations of color, 3-D, and multiple screens, and network capacity will need to increase ten- or twenty-fold, or more.
Consumer networks are already mostly carrying rapidly growing amounts of user-generated video content, IPTV and peer-to-peer traffic, and Cisco forecasts thatvideo will account for 90 percent of network traffic by 2013. Sure, there’s text and images and spreadsheets and slideshows traversing networks too, but it takes a lot of 140-character tweets to equal one full-length motion picture. Enterprises are increasingly adopting mobile, desktop, and immersive telepresence solutions. Meeting all this demand will require increased investment in wireless and wired networks.
IT will also be transformed. After all, how effective will databases that were designed for alphanumeric data be when a majority of future IT expenditures will be for acquiring, managing and maintaining enormous repositories of unstructured video for security/surveillance, merchandising optimization, field service, collaboration, depositions, entertainment, or applications we haven’t imagined yet?
