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 exiting 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.
Smoothing: It refers to the smoothness of the stream. The higher value of the smoothing, the
better fluency of the stream, though, the video quality may not be so satisfied. The lower value
of the smoothing is, the better quality of the stream would be, though it may appear not fluently.
Note: The video settings vary according to different camera models.
Audio
1. Enter the Audio Settings interface.
2. Configure the following settings.
Audio Encoding: G.722.1, G.711 ulaw, G.711alaw, G.726, MP2L2, AAC, PCM and MP3 are
selectable. For MP2L2 and AAC, the sampling rate and audio stream bitrate are configurable; for
PCM, the sampling rate can be set.
Audio Input: MicIn.
Input Volume: 0-100.
Environmental Noise Filter: Set it as OFF or ON. When the function is enabled, the noise in the
environment can be filtered to some extent.
Note: Audio settings vary according to different camera models.
3. Click Save to save the settings.
