System Architecture 2-5
Continuous Real-Time Feeds The OVS can store the most recent portion of a
continuous real-time feed , or an endless stream of one-step encoded video. A
continuous real-time feed enables a client to search the most recent portion of
ongoing video, such as the last 12 hours of a 24-hour-a-day news broadcast.
