Dual Streaming
In situations where the network bandwidth is severely limited, Recording at the Edge is a savior for high quality recorded video but it does not solve the challenge of needing to view live video over a restricted network. Some encoders support dual streaming. This is a concept that enables the encoder to deliver two totally independent streams of video, separately configured for different frame rates and video resolutions. Typically for limited bandwidth networks one high quality stream is used for local recording, and a lower quality, which translates to a lower bit rate, is used for viewing live. Conversely for high bandwidth networks, the same stream will be used to record locally and centrally, and Automatic Network Replenishment is used to fill any gaps in the centralized recording dues to network interruptions.

Famous quotes containing the words dual and/or streaming:
“Thee for my recitative,
Thee in the driving storm even as now, the snow, the winter-day
declining,
Thee in thy panoply, thy measur’d dual throbbing and thy beat
convulsive,
Thy black cylindric body, golden brass and silvery steel,”
—Walt Whitman (1819–1892)
“Who wants to become a writer? And why? Because it’s the answer to everything. To “Why am I here?” To uselessness. It’s the streaming reason for living. To note, to pin down, to build up, to create, to be astonished at nothing, to cherish the oddities, to let nothing go down the drain, to make something, to make a great flower out of life, even if it’s a cactus.”
—Enid Bagnold (1889–1981)
