Panasonic WJ-NT314 manual Calculation of refresh interval JPEG, Max number of MPEG-4 clients

and "Unicast port2 (Audio)" will automatically be selected when transmitting images and audio from the unit.

When it is unnecessary to fix the port number for MPEG-4 image transmission such as when using in a particular LAN environment, it is recommended to select "Unicast port (AUTO)".

Unicast port (MANUAL): Up to 8 users can access a single camera concurrently. It is necessary to select "Unicast port1 (Image)" and "Unicast port2 (Audio)" manually to transmit images and audio from the unit. It is possible to fix the port number of the router used for MPEG-4 image transmission via the Internet by setting "Unicast port (MANUAL)". Refer to the oper- ating instructions of the router in use.

Multicast: No concurrent access limitation for a unit. Refer to page 4 for further information about the maximum concurrent access number.

Default setting: Unicast port (AUTO)

Important:

When "Multicast" is selected, set the value of "Total bit rate" greater than the total value of "Max bit rate (per 1 client)" of all the channels.

[Max number of MPEG-4 clients]

Select the number of users to transmit MPEG-4 images at a time. Up to 8 users are available.

*MPEG-4 images are not transmitted from each channel to more users than the maximum number.

Available value: 1 - 8

Default setting: 4

Important:

•Depending on the PC in use for monitoring, the mul- ticast port number may be already in use. In this case, it may be impossible to monitor images. Change the multicast port number.

•When transmitting MPEG-4 image via a network, the transmitted image sometimes may not be displayed. In this case, refer to the network administrator.

•When two or more network interface cards are installed on the PC in use, the network interface card(s) not used for receiving images should be invalidated when displaying images using the multi- cast port.

[Unicast port1 (Image)]

Enter the unicast port number (used to transmit images from the camera).

Available value: 1024 - 50000 (Only even numbers are available.)

Default setting:

CH1: 32004

CH2: 32006

CH3: 32008

CH4: 32010

[Unicast port2 (Audio)]

Enter the unicast port number (used to transmit audio from the unit).

Available value: 1024 - 50000 (Only even numbers are available.)

Default setting: 33004

[Multicast address]

Enter the multicast IP address.

Images and audio will be transmitted to the designated IP address.

Available value: 224.0.0.0 - 239.255.255.255

Default setting: 239.192.0.20

[Multicast port]

Enter the multicast port number (used to transmit MPEG-4 images from the unit).

Available value: 1024 - 50000 (Only even numbers are available.)

Default setting:

CH1: 37004

CH2: 37006

CH3: 37008

CH4: 37010

[Multicast TTL]

Enter the multicast TTL value.

Available value: 1 - 254

Default setting: 16

■Calculation of refresh interval (JPEG)

It is possible to calculate an interval to refresh the dis- played JPEG image that can be transmitted to the max number of users accessing.

Calculated values are approximate. Refresh interval changes depending on the settings or the network sta- tus.

[Number of JPEG clients when connecting with max number of MPEG-4 clients]

The number of JPEG clients of each channel that can connect when the number of accessing MPEG-4 clients is maximum is displayed.
