Integration with Sony Network Camera

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.

VIDEO COMMUNICATION SYSTEM-TECHNICAL DOCUMENTATION

Integration with Sony Network Camera

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 bi-

directionally 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).

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.

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.

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

VIDEO COMMUNICATION SYSTEM-TECHNICAL DOCUMENTATION

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.

(This image illustrates the connection between video communication terminals and network cameras.

The screen image is simulated.)

User Authority

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.

Only those functions related to PCS integration are listed.

*1: Up to 6 preset positions can be used.

Through the PCS-G50/G70, you can call any of the six registered preset positions (No.1 to No.6) in the preset position

table in the network camera's Preset Position Menu.

*2: This function overwrites the network camera's settings. See the “Determined Communication Mode Based on

Authority” section for details.

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.

Operating with Administrator Authority in PCS Integration

•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.

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).

• 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.

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.)
