Items Descriptions
SRT Encryption
When the SRT function is turned
on, this option allows users to
select their desired SRT
Encryption way. There are three
encryption ways including AES-
128, AES-192 and AES-256 for
users to select.
SRT Password
When the SRT encryption way is
set, it is needed for users to use
this password. The default value
is 1234567890 and this
password can change by users.
SRT Bandwidth Overhead
The Bandwidth Overhead is a
percentage which is set
according to the network link.
You can multiply this percentage
value by the encoder-encoded
video and audio total bitrates to
get the maximum overhead
which is allowed by the
Bandwidth overhead. This value
plus the total value of the video
and audio bitrates is the
maximum value of the current
SRT transmission bandwidth,
which is the maximum
bandwidth of this SRT channel.
The purpose of the bandwidth
overhead is to transfer the
control message data packet
which accompany the SRT
streaming. Moreover, it also
includes the retransmission for
all of the media packets. If the
network link condition is worse,
