Switching Tcp/Udp Transmission Mode - Sony SNC-CH160 User Manual

Switching TCP/UDP
Transmission Mode
You can select TCP or UDP as the communication port
for video data.
This function can be used when Mode (video codec
mode) is set to MPEG4 or H.264 and the ActiveX
viewer is used.
Notes
• 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.
• If you are using Windows XP Service Pack 2 or later,
Windows Vista, or Windows 7, disable "Windows
Firewall". For details, see "Configuring Windows
Firewall" in "When using Windows XP Service Pack
2 or later" on page 9, "Configuring Windows
Firewall" in "When using Windows Vista" on page 11,
or "Configuring Windows Firewall" in "When using
Windows 7" on page 14.

Select TCP, Unicast or Multicast from the
Connection drop-down list in the Others panel.
TCP: This is normally selected.
When TCP is selected as the communication port,
HTTP communication is adopted for video
communications.
HTTP is the protocol used for reading the usual
Web page.
In an environment capable of reading Web pages,
you can watch video by selecting the TCP port.
Unicast: When Unicast is selected as the
communication port, RTP (Real-time Transport
Protocol) is adopted for video communications.
Since RTP is the protocol for running video data,
the video 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 may not play back
properly when Unicast is selected. In this case,
select TCP.

Switching TCP/UDP Transmission Mode

Multicast: This protocol is selectable when
Multicast streaming (page 47) is On. When
Multicast is selected as the transmission port, RTP
(Real-time Transport Protocol) and UDP multicast
techniques are adopted for video 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 may
not play back properly. In this case, select TCP or
Unicast.
