Scalable Video Coding (SVC) is the name for the Annex G extension of the H.264 or
H.265 video compression standard.
The objective of the SVC standardization has been to enable the encoding of a high-quality
video bitstream that contains one or more subset bitstreams that can themselves be decoded
with a complexity and reconstruction quality similar to that achieved using the existing H.264
or H.265 design with the same quantity of data as in the subset bitstream. The subset
bitstream is derived by dropping packets from the larger bitstream.
SVC enables forward compatibility for older hardware: the same bitstream can be consumed
by
basic hardware which can only decode a low-resolution subset, while more advanced
hardware will be able decode high quality video stream.
11.1.8 Smoothing
It refers to the smoothness of the stream. The higher value of the smoothing is, the better
fluency of the stream will be, though, the video quality may not be so satisfactory. The lower
value of the smoothing is, the higher quality of the stream will be, though it may appear not
fluent.
