With the H.265 codec in an optimal scenario and when Dynamic Intra frame is combined with

the Smart Stream function, an 80% of bandwidth saving can be achieved comparing with using

Comparing with Smart Stream II, Smart Stream III has two more congurable options: Smart Q,

and

Smart FPS.

NOTE:

By queuing the old frames from a static scene, both the computing efforts and the size of P

frames are reduced. It is benecial for keeping up with the frame rate requirements.

A default frame difference threshold, 1%, is embedded in rmware for returning from Smart FPS

to normal encoding when motions occur.

■ Smart FPS

In a static scene, the algorithm puts old frames in queue when no motions occur in scene. When

motions occur, the encoding returns to normal to deliver real-time streaming.
