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.

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.

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.

5.1.8 I-Frame Interval

I-frame interval denes 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.

5.2 Audio Sengs

It is a funcon to set audio parameters such as audio encoding, environment noise ltering.

Go to the audio sengs page: Conguraon → Video/Audio → Audio .

5.2.1 Audio Input

If a built-in microphone or an external audio pick-up device is available, audio encoding, audio

input mode and input volume are congurable.

Audio Encoding

The device oers several compression standard. Select according to your need.
