Profile: This function means that under the same bitrate, the more complex the profile, the higher the
quality of the image, and the requirement for network bandwidth is also higher.
I-Frame Interval: I-frame interval defines the number of frames between two 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 SVC standardization has been to enable 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 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 decode only a low-resolution subset, while more advanced hardware will be able
to decode high quality video streams.
10.1.8 Smoothing
This refers to the smoothness of the stream. The higher the smoothing value, the better the stream
fluency, though the video quality may not be so satisfactory. The lower the smoothing value, the higher
the stream quality, though it may appear less fluent.
10.1.9 Display VCA Info
VCA information can be displayed by Player and Video.
Player: The VCA info can be displayed by the dedicated player provided by the manufacturer.
Video: The VCA info can be displayed by any general video player.
10.1.10 Audio Settings
This function sets audio parameters such as audio encoding and environment noise filtering. Go to the
audio settings page: Configuration Video/Audio Audio.
Audio Encoding: Select the audio encoding compression of the audio.
Audio Input: Connect the audio input device as required.
The audio input display varies by device model.
LineIn
Set Audio Input to LineIn when the device connects to an audio input device with high output power
such as MP3, synthesizer, or active pickup
MicIn
Set Audio Input to MicIn when the device connects to an audio input device with low output power such
as a microphone or passive pickup
