Hello:
I see in the Hikvisin´s manual:
SVC:
Scalable Video Coding is an extension of the H.264/AVC standard. The technology encodes the video signal with layers;
the basic layer and several enhanced layers and it is adaptive to the network condition to transfer different video streams.
For example, when the bandwidth is limited, only the basic layer data is encoded and transferred. You can enable the function when you want o see the video with several terminals , such as the mobile phone with 3G network, or the personal computer with IP network.
