4. REMOTE PLAYBACK FUNCTION
(LAND-SHIP COMMUNICATION)
You can replay or extract the data from the PC on the shore by connecting the PC to
the on-board VDR through the satellite link.
Operate the Live Player V5 to use the remote playback function. For how to use the
remote playback function, see the Live Player V5 operator's manual (OME-44851).
This chapter explains the preparation and limitations about the remote playback func-
tion, and recommended network configuration.
4.1

Preparations

The following preparations are required to connect an on-shore PC to the on-board
VDR:
• The land-ship connection through a satellite link (ex. VSAT) must be established by
VPN connection. Check the communication between the on-shore PC and on-board
VDR, by sending a Ping request to the specified IP address.
• Configure the firewall to allow access to all network ports used for the land-ship
communication. This setting must be applied to all network devices. For the network
ports used by the VDR and Live Player V5, consult your dealer.
• The VDR must be configured to activate the remote playback function. Contact your
dealer to activate the remote playback function.
• When you want to connect the PC multiple VDRs, a unique IP address is required
for each VDR.
• The remote playback function uses UDP communication. Therefore, it is recom-
mended that the router on the communication path is compatible with the Path MTU
Discovery function.
• It is recommended to use a fixed charge satellite line for the remote playback func-
tion. If you use a satellite line with a meter-rate system, communication cost may
become expensive.
4.2

Limitations and Notifications

Keep in mind the following limitations and notifications to use the remote playback
function.

• Data extraction by LAN connection ([Long Term Device (LAN)] or [Long Term De-
vice (Save Area)])
• The remote replay function is not available when the on-board PC (Live Player V5)
is connecting to the VDR by LAN connection or RAP is extracting the data.
