SVC

Scalable Video Coding (SVC) is the name for the Annex G extension of the H.264 or H.265 video

compression standard.

The objecve of the SVC standardizaon 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 reconstrucon quality similar to that achieved using the exisng H.264 or H.265

design with the same quanty of data as in the subset bitstream. The subset bitstream is derived

by dropping packets from the larger bitstream.

SVC enables forward compability for older hardware: the same bitstream can be consumed by

basic hardware which can only decode a low-resoluon subset, while more advanced hardware

will be able decode high quality video stream.

MPEG4

MPEG4, referring to MPEG-4 Part 2, is a video compression format developed by Moving Picture

Experts Group (MPEG).

MJPEG

Moon JPEG (M-JPEG or MJPEG) is a video compression format in which intraframe coding

technology is used. Images in a MJPEG format is compressed as individual JPEG images.

Prole

This funcon means that under the same bitrate, the more complex the prole is, the higher the

quality of the image is, and the requirement for network bandwidth is also higher.

Smoothing

It refers to the smoothness of the stream. The higher value of the smoothing is, the beer uency

of the stream will be, though, the video quality may not be so sasfactory. The lower value of the

smoothing is, the higher quality of the stream will be, though it may appear not uent.

2.4.2 ROI

ROI (Region of Interest) encoding helps to discriminate the ROI and background informaon in

video compression. The technology assigns more encoding resource to the region of interest, thus

to increase the quality of the ROI whereas the background informaon is less focused.
