There are two options listed on the Client settings page:
• Media Option, which allows users to specify if audio should be muted
• Protocol Option, which lists the available communication protocols that can be established between the
client and the encoder
There are three protocols choices to optimize usage:
• UDP
• TCP
• HTTP
The UDP protocol enables real-time audio and video transmission. However, some packets may be lost
during heavy network traffic bursts, which can impact the video quality.
Selecting the TCP protocol will normally result in less packet loss, thereby producing better video quality.
Choosing this protocol may, however, increase latency resulting in a slight delay in the video transmission
depending upon the network infrastructure.
The HTTP protocol should be selected if the network is protected by a firewall and only allows HTTP
Port (80) to be opened. In this mode, only video is available and audio will not be sent. If no special need
is required, UDP protocol is recommended.
Generally speaking, the client’s choice will be in the order of UDP — TCP — HTTP. After the DDK-
3000 Video Encoder is successfully connected, “Protocol Option” will indicate the selected protocol. The
selected protocol will be saved to the user
’s
PC and will automatically be established during the next
connection. If the network environment changes, or the user wants to manually change the transmission
protocol, simply open the Client settings page, select the desired option, save, and return HOME to re-
connect.
