Streaming Video Basics

Because the name advertisements are small and only sent periodically, they have practically no impact on the network. These advertisements are typically sent to a default multicast address, but may be configured to be broadcast or configured to be sent to any valid IP Address.

Once the call is established, the calling party may "ring" the other end to get their attention, if desired.

•Several configuration options are available:

•Enable/Disable Conference.

•Enable/Disable Ringer.

•Auto answer – the party receiving the call does not have to answer. The VBrick automatically receives the call and two-way video is instantly available.

•Manual Answer – the party receiving the call must answer it before the call is established.

•How often to advertise the Call Name.

•The address on which to advertise the Call Name.

•Two-way interactive conferencing may be initiated from the IR remote handheld device.

VBrick Accessories

VBrick units have a number of optional hardware accessories, including the AudioMate microphone, remote control devices and cameras. These work directly with VBrick appliances or through the use of ActiveX control software, also available from VBrick. For information about microphones, cameras and other VBrick hardware accessories, please contact VBrick directly. ActiveX controls for cameras and other software accessories are also available from VBrick.

Serial Port Passthrough

When configured properly, VBricks provide full duplex, end-to-end transparent passthrough of user data from one VBrick to another, or to other IP devices. Two serial ports are provided, each independently supporting this feature. COM1 is dedicated to Passthrough. COM2 is normally used for management control, but may be configured to support Passthrough, depending on the VBrick hardware revision. Each serial port operates at its configured baud rate (e.g. 110 to 115.2K bps). See the MPEG-2 or MPEG-4 Admin Guide for configuration details. Some common applications include:

•Remote control of a camera, pan-tilt-zoom.

•Remote control of a security door lock.

•Low speed data transport.

•Data collaboration between PCs.

Note Passthrough mode is used to send control information from one VBrick to another and may not support sustained data at higher data rates.
