Chapter 5: Data

Conference

This chapter shows you how to use the data from a computer, etc. connected to the optional PCS-DSB1 Data Solution Box for a conference.

The optional PCS-DSB1 Data Solution Box is equipped with various input/ output connectors. For example, connecting the RGB output on a computer enables you to transmit the pictures or text data displayed on the computer to a remote party. When you connect a projector, you can display a high- resolution image from a computer on the projector at a high transmission rate. The PCS-DSB1 is also equipped with connectors for connecting active speakers and microphones. The PCS-DSB1 is connected with the Communication Terminal using the interface cable for exclusive use.

The party who receives the data, even if the party has no Data Solution Box or uses another videoconferencing system such as PCS-11/11P, PCS-G70/G70P, PCS-TL50 and PCS-1600, can view the computer images sent from the other party. However, the quality of the picture received varies with the components of the system. If the Data Solution Box is used by the party who receives the data, a larger number of frames per second is obtained than the system without the Data Solution Box. It allows you to obtain a high-resolution motion picture from a computer.

For details on picture quality depending on the system components, see “Picture quality of the data solution box” on page 138.

For details on RGB signal specifications, see “Acceptable RGB Input/Output Signals” on page 219.

Restrictions on the IP address of the system when using the Data Solution Box

The IP address available for the PCS-1/1P Video Communication System is restricted when you use the Data Solution Box. Moreover, a network for communication between the Data Solution Box and the Communication Terminal should be set up to be a separate segment.

As a result, unusable IP address is the value obtained from the AND operation with the address of the Data Solution Box for communication and the network mask.

(Unusable IP address for the PCS-1/1P) = (IP address of the PCS- DSB1)&(Network mask)

The IP address of the PCS-DSB1 is fixed at “192.254.1.2”. If the Network mask is assumed to be “255.255.0.0”, an unusable IP address is as follows:

192.254.m.n (0 m 255, 0 n 255)

Note on the camera picture when using the Data Solution Box

When transmitting a signal via the Data Solution Box, the camera picture quality will be lower owing to the decreased number of frames.
