After 15 years in the industry and hundreds of successful VideoConferencing installs there’s not much we haven’t seen, and we’ve learnt a lot about the important things to consider in the initial planning stages of VideoConferencing projects.
When they do, they will first see a small window displaying their available cameras (as shown above on Page 5). After they click to join, the Mikogo video window will appear on their screen, which contains video stream tiles with the faces of all participants and the organizer.
Continuous Presence enables you to view up to nine sites on your video screen at one time. These features need to be requested at the time of the reservation. (Descriptions of all of the Continuous Presence features that we offer follow.) Continuous Presence is best when used with smaller groups of people at each video site. This option enables you to view the other participants on the video call at the same time for round table discussions or interactive meetings.
Bowling Green Facilitators are student employees of AVS. They will provide full technical support for classes that originate from a WKU-Regional campus or when you are traveling to teach from a WKU-Regional campus. AVS will be glad to work with you to arrange for BG Facilitators, as needed. Please note that these students are trained to provide videoconferencing technical support and are not trained to proctor exams or in classroom management.
The Visual Concert FX and the Visual Concert VSX People + Content accessory connects a laptop or desktop PC to the Polycom unit, letting you share live PC graphics during a videoconference. It can sit on your conference table or be mounted under the table or in a cabinet. It connects to the mic port on the back of the video codec, with the mic pod(s)
Introduction: What is Desktop VideoConferencing? This guide aims to provide an introduction to Desktop VideoConferencing. You may be familiar with videoconferencing, where participants typically book a designated conference room and communicate with another group in a similar room on another site via a large screen display. Desktop videoconferencing (DVC), as the name suggests, allows users to video conference from the comfort of their own office, workplace or home via a desktop/laptop Personal Computer. DVC provides live audio and visual communication in real time from a standard PC and allows one to one and multiple user conferences by participants in different physical locations. Some software features a ‘whiteboard’ on the computer screen for information exchange and the option to show or share documents and websites between the participants.
The dynamic Continuous Presence (CP) capability of the Collaboration Server system enables viewing flexibility by offering multiple viewing options and window layouts for videoconferencing. By default every conference, Entry Queue and Meeting Room has the ability to declare the maximum CP resolution as defined for the system. This includes conferences launched by the Collaboration Server Web Client and conferences started via the API.
At this time, there are three state Universities in R. Macedonia: “Ss Cyril and Methodius” in Skopje, “St Kliment Ohridski” in Bitola and “State University of Tetovo” in Tetovo. There are also several private Universities, but only three have more than 1000 students: the biggest one is the South Eastern University in Tetovo (SEU), but there are also European University and FON University, both from Skopje. Four out of six Universities have compatible videoconferencing equipment, but they lack the organized approach of their usage and the telecommunication infrastructure that will enable relatively high bandwidth of IP traffic needed for videoconferencing service.
Having the walls, tables and carpets identical across telepresence rooms allows them to naturally blend together. The more effectively this is done the more likely you will feel the video participants are in the same room and vice versa. This effect is further enhanced when screens bezels are removed. Some companies achieve this by projecting the video connected participants onto a transparent screen removing any chance of difference between backgrounds.
Into the future, the Midwest Health Service is looking to extend our very willing group of volunteer support carers into a client advocate role where they can support new clients accessing video-conferenced appointments. Education and support remain imperative to sustain the viability of this service, however it is equally important to recognise that this is a service enhancement model and does not remove the need for continued face to face contacts within local communities by allied health clinicians. So in summary, the Midwest Health Service recognised a need to improve the support and direction of therapy assistants and elected to use the video-conferencing option for this increased support. This required the following process:
The use of PowerPoint slides was a key factor in the delivery of the video conferences in this study, yet little thought was given to the impact that these slides would have on teaching and learning. Qvist (2007, p1) makes the point that PowerPoint slides are used in thousands of classrooms all over the world every day, which raises the question, “Do PowerPoint slides support learning?”. It is true that PowerPoint slides can help presenters to organise themselves (Qvist, 2007, p4), but it is argued by Tufte (2003, p4) that this can also bring with it much unnecessary “PowerPoint Phluff”, such as automatic hierarchy and inappropriate data presentation. In particular, Tufte disagrees with reading aloud from PowerPoint slides and suggests that they should only be used to display images / graphics that cannot be reproduced as printed handouts (Tufte, 2003, p24). He further argues that the core ideas of teaching are explanation, reasoning, finding things out, questioning, content and credible authority, which he claims are contrary to the “market-pitch approach” of PowerPoint (Tufte, 2003, p13). In response to Tufte’s criticisms, supporters of the software would argue that whilst it is often misused, it should be recognised that PowerPoint is a medium rather than a method and that it can be used effectively with effective instructional methods (Atkinson, 2004, p2). This allows us to draw an interesting analogy with videoconferencing, which itself can be considered as either a medium or a method. Given that the answer to the earlier question about whether PowerPoint supports learning is arguably that it can if the correct teaching strategies are used, then it could further be argued that the same is true for videoconferencing.
The term videoconferencing is used very broad and covers in day-to-day use everything that uses a video stream to connect between two or more persons. There is a large distinction between webcam quality connections and a video connection via a dedicated video device. First of all is the codec for a webcam and the associated software, like Skype, instructed to use a small amount of bandwidth to get a decent video quality. This quality can be perceived as hindering in the conversation and therefore do more harm than good to the experience. Second, with the use of webcam software most of the time the infrastructural issues are not met, though broadband internet is more and more a common good, bandwidth is not guaranteed most of the times. Especially for multipoint videoconferencing this will be problematic, as much larger bandwidth is needed.
Existing SIP Model support one-to-one communication with all clients, and it is used for remote conference, and each host which is participating in the conference must communicate with the conference server. Each SIP client sends its audio and video stream to conference server. When conference server receives all streams from SIP client, it selects some streams, mixes them, and distributes it to each SIP client. In other words, conference server holds one-to-one conference with all SIP clients. Therefore, when the number of SIP client increases, network load on conference becomes heavier, and if many hosts participate in the same conference, conference server may become over load which create bottle neck in conference server, and conference server may stop. Then conference system is no longer operational mode. The simplest solution of this limitation is to use multiple conference servers to balance the load of mixing and distribution. The number of Conference Server and its location is unchangeable. But, the number and location of SIP clients change dynamically, so required number of conference servers which are at optimal place for load sharing cannot necessarily be provided in accordance with the number and location of hosts by this method.
The announcement of new participants joining the conference is linked to the multiple streams issue. In our implementation, the MCU does not inform the former participants that a new user joined the conference, it just starts forwarding the flows coming from this new user to the other ones. As explained in 5.3.5 (Announcing new participants), using re-invite messages and announcing new media flows in the SDP with the sendonly attribute seems to be the optimal solution to solve this problem, since the SIP clients would not need to support multiple streams in the same port. Also, we avoid the problem of ensuring everyone in a conference can receive all types of media sent (5.1.3, SDP media dealing), since the clients would reject all re-invites with SDP offers including unsupported media types.
The application programming interface (API) to access multimedia devices is often incapable of supporting conferencing. The most common reason for this shortcoming is that the API was designed to support a different class of applications. Prime examples are the WAV audio and VIDCAP video capture APIs in Microsoft operating systems. The available device drivers for these systems evolved out of capture applications that recorded multimedia data to disk. As a result, it is almost impossible to capture video data without storing it to disk, and the interactive recording and playback of audio re quires the complicated management of a large number of buffers, as buffering capabili ties are not offered by the device^ Microsoft has responded to the demands of the new real-time applications, and new audio and video capture interfaces are being designed and made available. The available UNIX operating system variants offer significantly more flexible programming interfaces with similar characteristics and can better support conferencing applications. Extensions however are still required to accommodate some of the real-time performance requirements, especially those of audio [Rizzo, 1997].
A Civicom operator conducts the conferencing process for you. Operators dial out to your participants, greet participants as they join, mute or unmute lines, and whatever else you need. Request an operator-assisted call to avoid the hassle of managing the call by yourself. An operator is especially helpful when you have too many participants to handle on your own. With a Civicom operator on your call, you can focus on what really matters. Civicom offers a variety of solutions for your needs, including event conferences, interviews, focus groups, webinars, webcasts – to mention a few. Call Civicom and we will be more than happy to meet your needs.
Previous works focus on performance comparison of network traffic (without considering video and VoIP traffic) between both MPLS and non-MPLS networks by simulation. The related work for comparing the real-time voice commun- ications between MPLS and non-MPLS had done either through analytical models or from theoretical analysis ,, , ,and . In the authors mainly focuses on comparative analysis of MPLS over non-MPLS networks and different type of LDP (Label Distribution Protocol) are discussed with respect to TE.
When a large number of employees in a group work at home or at other nontraditional locations, using computers to telecommute and to collaborate with others, the result is a virtual office. Employees may receive work through electronic messaging and information sharing systems. Workflow management systems may be used to coordinate the work. Electronic conferencing systems may be used to allow employees to collaborate on ideas. Employees can work wherever they happen to be; the office exists where the employees are. Virtual offices compound the advantages and disadvantages of telecommuting because the number of people involved tends to be greater. In addition, more sophisticated software is needed so that electronic conferences and meetings can be held. Still, so many employees telecommute that virtual offices are becoming increasingly common.
There remains an issue of how the teacher is to handle the very small number of persistent ’refusers’. To some extent the strategies employed are little different from those to encourage reluctant students in any lesson. In addition, videoconferencing was explained by some teachers as a chance to practise skills that would be useful in the world of work in a safe and familiar environment. However, none of the schools were willing to insist that all students participate if they really objected and most relied therefore on voluntary systems for involvement. The exception was the post-16 students in the language college who were required to have a regular one-to-one video conference with a student from the target language, as it was seen by both students and teachers as the best way of gaining authentic access.
