Switching Transmission Mode - Sony SNC-CH115 User Manual

Switching Transmission
Mode
You can select the Transmission mode for video/audio
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 12,
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, 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, 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.

Multicast: This protocol is selectable when
Multicast streaming (page 48) is On. When
Multicast is selected, 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.
Note
When you are connected to a Proxy server, Unicast
or Multicast cannot be selected.
