A hybrid system for multimedia conferencing

The system of any of claims 1 - 3 wherein at least one of said participating terminals 31, 32, is a high-capacity-linked HCL terminal while at least one of said participating terminals 31 is a low-capacity-linked LCL terminal.

This is of particular advantage in the case of conferences with a small number of participants typically up to 5, 6 or 7 because it does not require the assistance of an expensive multipoint processor.

It is vital however to look at the facts and understand where security breaches are most common in organisations of your type and size. An organisation has no need to let any untrusted source through the firewall and onto the MCU.

T1 A hybrid system for multimedia conferencing itself to receive a media stream and sends the transport address where it is listening for the media stream to the MC in an OpenLogicalChannelAck message.

No media processing is done by the MD and every terminal 31,32,33 still receives all N-1 streams sent by the other and process them locally. The MC will then create the required MD accordingly and instruct the requesting terminal to send its media to the created MD. Thus, there is no need for a multipoint processor.

As a consequence, the advantage of the distributed system will be preserved because no complex multiprocessor is required as in system 1 Fig. T1 then starts the H. Some may be surprised as who they should actually be protecting their network from!

Again, the exact number of terminals again is not limited to three terminals as shown in Fig. Assuming the terminals use the procedures defined in H. In centralized multipoint conferencing all participating terminals send their media streams to a multipoint processor MP via unicast point-to-point deliveries.

However, the number of participants within a conference is limited by the number of media streams which a terminal can process in parallel, and by the total network capacity consumed by the distribution of the media streams.

The multipoint distributor 30 distributes a media stream in the following manner: Risk is involved with recording conferences, and sensitive information is being stored, so to ensure recordings are not lost through transport, intercepted or damaged, a private on-premise solution should be considered.

It is to be noted that the number of terminals could be smaller or greater than shown in Fig. Example The following specific but not limiting example illustrates how the invention can be used in a conference by means of a conferencing system with three participating terminals T1, T2, T3 and a multipoint distributor MD.

Recording No matter how good the cloud is, and whether the service provider has achieved ISO security requirements, VideoCentric believe that many organisations would be better off with hosting a recording server on-premise.

Hybrid Systems

In other words, any terminal that is associated with an MD, sends at least one or all of its media streams to the MD while it receives media streams either directly from the other terminals or from other MDs: There is no one solution fits all model.

The term "media stream" as used herein is intended to refer to audio streams, video streams, text streams, shared object streams e. Many Cloud solutions such as Cloud Based Virtual Meeting Rooms can provide the interoperability between different protocols, with the software instantly upgrading as new inteoperability features are released, allowing everyone to communicate, whatever system or device they are using.

Brief Description of the Drawings The invention will be discussed in more detail with reference to the enclosed drawings intended to illustrate the invention without limiting it. Or a limited ISDN gateway. Then T3 starts to send media data to the multipoint distributor which distributes it to T1 and T2 as previously described.

Typically, up to ten terminals can participate in a conferencing system according to the invention and one, or more, or all of the terminals can be associated with an MD of their own.

ADSL asynchronous digital subscriber or hybrid accesses with normal modem for up-link and cable modem for down-link. When comparing the two multipoint conferencing methods just mentioned, the distributed approach has the advantage of not requiring an expensive MP.

Cloud vs On Premise vs Hybrid

In contrast, a conventional distributed system 2 would consume the entire capacity of the access link. The exact number of terminals again is not limited to three terminals as shown in Fig.

Voice over Internet Protocol VoIPincluding next generation networks with a packet-switched transport layer Description Field of the Invention The present invention generally relates to the exchange of electronic data between a plurality of terminals and specifically to distributed multipoint conferencing.

The system and method according to the invention is scaleable for a large number of conferences because the MD 30 is quite simple to implement because it redistributes only those media streams which it receives from the associated terminal 31 to the rest of the terminals 32, 33 etc.

The system of claim 1 comprising from 3 to 10 participating terminals 31;32, However, businesses do need to be beware of any hidden costs associated with some clouds. On the other hand, a conferencing system according to the invention may include more than one multipoint distributor in which case each multipoint distributor receives at least one media stream from its associated terminal; by the same token, all terminals of the system could be connected to, or supplied with, an associated multipoint distributor.

It includes a number of terminals 11,12, 13 etc. Detailed Description of the Invention The inventive system and method will now be discussed in more detail with reference to the figures.

It is to be noted, however, that if it participates in a three-party conference using the distributed multipoint conferencing system 3 according to the invention or the corresponding method embodiment, some capacity would remain available for other applications.

The system of claim 1 or 2 wherein any multipoint distributor 30 in the system 3 is implemented in a general-purpose computer with a networking system. Assuming that a terminal accesses the network via a standard-type The same happens for T2.

Terminal 31 gets support from the multipoint distributor Some organisations may benefit from pushing all their communications into the cloud.real-time video conference system has hybrid Peer to Peer architecture based on a client-server and peer-to-peer, real-time video conference system using high speed multimedia communication.

In the following sections, we begin with the architecture of real-time video conference system, and implementation of. Multimedia system provides seamless provision of multimedia services to its user.

The conferencing system ensures that voice, video and other media forms are streamed efficiently to various individuals ensuring smooth real time communication. Currently, this multimedia system does not support this facility in all the mobile operating system.

Hybrid Systems Ricardo G. Sanfelice The Technical Committee on Hybrid Systems is dedicated to providing informational forums, meetings for technical discussion, and information over the web to researchers in the IEEE CSS who are interested in the field of hybrid systems and its applications.

Historically, many video conferencing solutions have had difficulty communicating with other video conferencing solutions, due to manufacturer differences, protocols (SIP/H), age and current network infrastructure set up.

multimedia conference, i.e., Conference Control (CC), is the kernel of a conference system, which should be performed under the cooperation of both server and.
