Switching Transmission Mode - Sony Ipela SNC-VB600 User Manual

Switching Transmission
Mode
You can change the transmission mode for video/audio
data.
This function can be used when the video codec mode is
set to H.264 and the ActiveX viewer is used.
Note
The function may not operate correctly if you use
personal firewall software or antivirus software on your
computer. In that case, disable the software or select the
TCP mode.

Select TCP, Unicast or Multicast from the
Connection drop-down list in the Others panel.
TCP: This is normally selected.
When TCP is selected, HTTP communication is
adopted for video/audio communications. HTTP is
the protocol used for reading the usual Web page. In
an environment capable of reading Web pages, you
can watch or listen to video/audio by selecting the
TCP port.
Unicast: When Unicast is selected, RTP (Realtime
Transport Protocol) is adopted for video/audio
communications. Since RTP is the protocol for
running video/audio data, the video/audio playback
is smoother than when TCP (HTTP) is selected. If
a firewall is installed between the camera and the
computer, or depending on the network
environment, video/audio may not play back
properly when Unicast is selected. In this case,
select TCP.
Multicast: This protocol is selectable when
Multicast streaming (page 22) is On. When
Multicast is selected as the transmission port, RTP
(Real-time Transport Protocol) and UDP multicast
techniques are adopted for video/audio
transmission. By selecting it, the network
transmission load of the camera can be reduced. If
a router that does not correspond to a multicast or
firewall is installed between the camera and the
computer, video/audio may not play back properly.
In this case, select TCP or Unicast.
Note
When connecting via a proxy server, neither Unicast nor
Multicast can be selected.
