Introduction

The Sony Visual Communication System PCS-G50/G70 is the first in the industry with features that allow connection with network cameras. These features allow you to connect to Sony network cameras as if you were calling a videoconference partner. In addition to viewing network camera images through the PCS-G50/G70, audio exchange is also possible between the PCS-G50/G70 and the network cameras, and pan, tilt and zoom operations can be performed on network cameras through the PCS-G50/G70. Furthermore, the cameras can be used to conduct multipoint conferences with a mixture of connections, such as IP and ISDN. These integration features expand the potential of new applications beyond conventional videoconferencing. This document describes the network camera integration features supported by the PCS-G50/G70.

* In this document, PCS-G50/G70 refers to both the NTSC PCS-G50/G70 and PAL PCS-G50P/G70P models.

Main Features

Video/Audio Types

H.264 and MPEG4 are supported for video (for single codec only). G.711 is supported for audio. You can monitor real-time network camera images and transmit voice data bidirectionally through the PCS-G50/G70 during a videoconference.

Easy Connection

Through the phone book (called the “network camera list”) of the PCS-G50/G70, you can easily connect to a network camera using a procedure similar to that for videoconferencing. You can register up to 20 network cameras in the network camera list.

• The network camera list is separate from the 500 items in the ordinary phone

book.

• Private and shared phone books are not supported.

• To register a network camera in the network camera list, see the PCS-G50/G70

Operating Instructions Manual (Version 2.6).

VIDEO COMMUNICATION SYSTEM-TECHNICAL DOCUMENTATION

Multipoint Connection

Up to 6 points (including the local site) can be connected, and split-screen viewing is possible. Multipoint connection in a mixed IP (H.323/SIP) and ISDN environment is possible for video communication terminals.

• For multipoint connection, MCU software for LAN connection (sold separately)

is required.

• For multipoint connection in a mixed SIP and ISDN environment, SIP software

and MCU software for ISDN connection (sold separately) are required.

Far End Camera Control

You can use the far end camera control function when connected to a network camera. The procedures for acquiring broadcast permission for the target network camera and for controlling the far end camera are the same as for when the PCS-G50/G70 is used at a remote site.

• To use the far end camera control function, you must have the proper permission

settings. (See p.5.)

• If the far end camera control function is enabled by the PCS-G50/G70, it can

also be used from video communication terminals as sub-terminals.

• The far end camera control function can be used in full screen display mode

only.

Page 4

Integration with Sony Network Camera

Preset Function

You can use the preset function (from 1 to 6 preset positions) for the network camera connection. You can also register preset positions through the PCS-G50/G70. The procedures for registering and calling up the presets are the same as for when the PCS-G50/G70 is used at a remote site.

• To use the preset function, you must have the proper permission settings.

(See p.5.)

Status Indication

As with the videoconferencing connection, you can use the Status menu for the network camera connection to check the communication status during communication, as well as the previous communication status while not in communication.

• When using a TCP connection, lost and recovered packet counts are not

displayed.

VIDEO COMMUNICATION SYSTEM-TECHNICAL DOCUMENTATION

Web Function

Using Microsof®Internet Explorer®(version 5.0 or higher, 6.0 is recommended), you can access the PCS-G50/G70 to perform control and change settings for a network camera.

Terminal Name Indication

You can use the terminal name indication function for the network camera connection. When this feature is enabled, the name of the title bar configured on the System Menu of the connecting network camera is displayed on the videoconferencing screen.

Other Precautions

You cannot perform the following PCS-G50/G70 functions when connected to a network camera (even between videoconferencing terminals):

• Sending/receiving a presentation image

• Sending dual video

• Sending a still image

• Encrypted conference

• Cascade connection

Page 5

Integration with Sony Network Camera

For the reasons outlined below, do not connect to network cameras used for monitoring. It is recommended that network cameras be installed exclusively for videoconferencing.

• The PCS-G50/G70 does not support JPEG. JPEG recording may stop when the

PCS-G50/G70 is connected to a monitoring system where Sony Recorder Software (RealShot Manager, IMZ series), Sony Network Recorder (NSR series), etc. is used.

• Connecting a video communication terminal to a network camera used for fixed

monitoring and far-end controlling may result in a loss of monitoring information.

When the SNC-RX550N/RX550P is installed on a desktop, the video image will be displayed upside down. The PCS-G50/G70 has no vertical flip function.

VIDEO COMMUNICATION SYSTEM-TECHNICAL DOCUMENTATION

User Authority

(This image illustrates the connection between video communication terminals and network cameras. The screen image is simulated.)

Multiple users can be registered for a Sony network camera, and a name, password and authority can be specified for each user. Connection from the PCS-G50/G70 to a network camera is made using a predefined user name and password. The operation and settings for a network camera can be limited based on the user authority.

Network Camera User Authority

Table 1 shows the functions available for the administrator and user authorities.

Operating with Administrator Authority in PCS Integration

When you connect using the administrator authority, you can change the settings of a network camera from the PCS-G50/G70. You can change the settings through the Network Camera page in the PCS's General Setup menu. If "Auto" is selected for "Bit Rate," "Frame Rate," "Mode" and "Image Size," the connection is made using the settings of the connecting network camera. If the connection is made using the administrator authority with the setting items set to "Auto," the connection can be made by properly changing the network camera settings even if a preconfigured item in the network camera setup is not supported by the PCS-G50/G70. For details on the communication modes supported by the PCS-G50/G70, refer to "Basic Specifications" at the end of this document. In addition, the far end camera control and preset functions can be used under the administrator authority. When the network camera settings are changed via the PCS-G50/G70, the previously set network camera settings are automatically restored after communication has ended.

Note

• Connections made using the administrator authority automatically change the

network camera settings and may affect a monitoring system using the network camera, so you must consult with your system administrator beforehand.

• If a connection shuts down due to a failure such as a blackout, the settings

cannot be restored. It is therefore recommended to save the camera's setting data in a file prior to connection. For details on how to save/restore the setting data, see the User's Guide that came with the network camera.

Page 7

Integration with Sony Network Camera

When a connection to a network camera is made using the administrator authority, the modes described below will automatically be changed.

• Audio Codec

If the audio codec setting (used to send audio) of the network camera is G.726, it will automatically be changed to G.711.

• Audio (Bidirectional)

If the audio upload setting of the network camera is disabled, it will automatically be enabled to perform voice communication from the video communication terminal to the network camera. If the microphone setting of the network camera is OFF, it will automatically be turned ON to perform voice communication from the network camera to the video communication terminal as well.

• Multicast Streaming

If the multicast streaming setting of the network camera is OFF and the connection is made through UDP (Multicast), multicasting will automatically be turned ON for the connection using UDP (Multicast).

VIDEO COMMUNICATION SYSTEM-TECHNICAL DOCUMENTATION

• Unicast Streaming

If the network camera's unicast streaming setting (video or audio port number) overlaps with the port number used by the PCS-G50/G70, it will automatically be changed to another number for connection.

Operating with User Authority in PCS Integration

You cannot change the network camera setting items through the PCS-G50/G70. You must use the network camera to configure settings related to the connection with the PCS-G50/G70. (Settings configured through the Network Camera page in the PCS's General Setup menu will be disabled.) To use the camera control and preset functions via the PCS-G50/G70, you must properly configure the network camera's User menu. (See Table 1.)

*3: If the network camera bit rate is configured as 2048kbps for camera 2, the sum of the bit rates of the sub-terminals

(communication terminal and camera) exceeds 4Mbps of the PCS's LAN Bandwidth because the network camera bit rate does not include audio (G.711 = 64kbps).

When the sum of the bit rates of the sub-terminals (2048kbps for communication terminal + (2048kbps + 1024kbps) for cameras) exceeds the main PCS's LAN bandwidth (4Mbps) due to the connection of the sub-terminal, the bit rate is changed to the optimum value for camera 2 regardless of the main PCS's network camera settings, but the mode for camera 3 is changed to "Voice Only" because user authority access is allowed and capability exchange cannot be performed again.

* In this example, the main terminal connects to cameras 2

and 4 with the administrator authority and camera 3 with the user authority.

When the frame rate exceeds the main PCS's frame rate limit (30fps x 4) due to the connection of camera 4, the capability exchange of the frame rate is required regardless of whether the administrator or user authority is used. In this example, the main PCS automatically tries to adjust the frame rate of all the sub-terminals to 15fps, but the mode for camera 3 is changed to "Voice Only" because user authority access is allowed and capability exchange cannot be performed.
