I-Frame Interval
I-frame interval deî´ªnes the number of frames between 2 I-frames.
In H.264 and H.265, an I-frame, or intra frame, is a self-contained frame that can be
independently decoded without any reference to other images. An I-frame consumes more
bits than other frames. Thus, video with more I-frames, in other words, smaller I-frame
interval, generates more steady and reliable data bits while requiring more storage space.
SVC
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.
12.1.8 Smoothing
It refers to the smoothness of the stream. The higher value of the smoothing is, the better
î´«uency 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 î´«uent.
12.1.9 Display VCA Info
VCA information can be displayed by Player and Video.
Player
Player means the VCA info can be displayed by the dedicated player provided by the
manufacturer.
Video
Video means the VCA info can be displayed by any general video player.
