The Future of Digital Video
Digital Enrichment for the Home Intelligent set-top boxes
will bring new levels of functionality to the home entertainment
experience. Set-top boxes will stream programming from
anywhere in the world to enable true video on demand,
whether the programming is stored on a home computer
or occurring live. Set-top boxes will also integrate home
surveillance security systems into the heart of the home
entertainment center to enable viewers to identify visitors at
the front door visually on their TV screens without having to
leave the couch. Through object/facial recognition technology,
the security system will be able to automatically identify family
members and let them in without a key. We will have our
entertainment anywhere and at any time we want it. Set-top
boxes will automatically set their own clocks, making recording
programs as simple as a single button push. And with voice
recognition technology, users will be able to adjust the volume
or change channels by voice command without having to hunt
for an elusive remote-control.
