HIKVISION DS-2DE2A204IW-DE3 User Manual

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.
