Desktop Conferencing System has become immensely popular in substituting real meetings and conferences, as time cannot be compromised in today world. Inevitably it is not easy to simply replace these vital meetings. Thus a commendable, reliable and an efficient system is required to replace these meetings and conferences. This is where MLABS Multimedia Conferencing System version 6.0 or popularly known as MCSv6 comes in.

Our Ability, Your Advantages |
||
|
MCS is a full-fledged versatile multipoint video conferencing system that can seamlessly integrate into the current network architecture of an organization. The best part of MCS is that it was designed to fit into any existing LAN and WAN environment. The key point that has always been stressed throughout the development is flexibility. Realizing the amount of money invested in setting up a networked environment, changing the whole or part of the architecture for a product is not acceptable, let alone economical. MCS was developed with this in mind. Another major advantage of MCS is that it is software based and uses non-proprietary hardware. This means your existing multimedia PC can probably be an MCS client, as long as it meets the basic requirements needed to run MCS.
|
||
Client Server Based |
||
|
MCS is the only Desktop Video Conferencing system that uses the RSW Control Criteria. MCS is also a client-server based system which supports distributed network entities. MCS allows up to 1000 users per server and the number of servers are scalable. This means a conference can have an UNLIMITED number of participants per conference by simply increasing the number of servers.
|
||
| Full Motion :- | ||
|
MCS can transmit and receive audio and video in real-time and in FULL MOTION. It provides smooth audio and video transmission and playback. It also allows video streaming of VCR/DVD movies, mixed commentaries (audio inputs), record meetings and act as a high tech public address system. These are all the standard built-in features in MCS.
|
||
MCS Client Entity |
||
|
MCS is not just a client-server based application, but one that supports distributed network entities. The client entity is the user based GUI application that works on the end user’s PC. The main modules of this entity are the MCS Main Control and MCS Conference Control, which do all the coordination and synchronization job for this entity. Basically, their main functions are:- |
||
Functions of MCS Main Control :- |
||
| • Provides control for login/logout and chat • Provides control to create and join conference for MCS mode • Provides control to call and hang-up for H323 mode • Provides control to switch status (Available, Busy, Away) • Provides control to switch between H323 mode or normal MCS mode, prior to login • Provides communication interface with servers for MCS • Provides user list for chat and Document Conferencing modules • Provides feedback of client and server messages to users. • Loads and handles synchronization of chat, MCS conference monitor or H323 module. |
||
Functions of MCS Conference Monitor :- |
||
| • Loads and handles synchronization of audio, video and Document Conferencing modules • Provides control to access audio/video/ Document Conferencing features • Start/Stop transmission for chairman/active users • Align video window relative to screen • Mute speaker/microphone • Set Video Resolution/Frame Rate/Property • Provides control for conference control |
||
| • User: Request, Release, Unqueue, Leave | ||
| • Chairman: Change Status, Invite, Remove, Drop, End | ||

The mixer is used by mcs to control individual playback volume and microphone volume. User can still be able to talk to other user and listen to them. The only thing the user will not be able to do is to set or modify the volumes through mcs volume slider in MCS Conference Monitor.
|
|
|
Q
|
How do I change the volume if my soundcard does not support mixer control? | |
|
A
|
To change the playback and microphone volume, use the system control panel. | |
|
Q

How do I get a single monitor fix mode with 320×240 video? | |
|
A
|
To get 320×240 video fixed mode on a single monitor, you need to have a screen resolution of at least 1280×1024. Smaller screen resolution than that will cause some of the video to be offscreen. | |
|
Q
|
What needs to be done if a prospect wishes to connect their legacy H.323 equipment and software? | |
|
A

It is quite easy. Logout of the server. At this point, you only have 2 active buttons on your desktop. The login and the last button. This last button or right most button on your client toolbar is a blue square MCS button. If you click on this, it will give you the MCS or H.323 option. Choose H.323 and then click login to login to the server. Once you have logged in, you are now an MCS H.323 client. Have fun using it.
