....lighting. All of these were lessons we learned in the process of installing the lighting. Finally, having six different zones creates yet another system to properly configure before putting on an event[5] The other miscellaneous issue that is a significant challenge in the CTL is floor control[8]. Floor control primarily concerns determining how remote sites participate in the main site. If there is a question from a remote participant, how should it be handled Using video on the side screen (see Figure l(a) a presenter might see a hand go up signaling a question, but often the ....

....the feeling of really being together. Moreover, telelectures have proofed rather poor with regard to interactivity and students becoming actively involved. Even new mechanisms and policies to provide more flexible access to microphone and keyboard, did not change this situation tremendously (cf. [ 19]) In contrast to human interaction, there is a much higher motivation to perform laboratory experiments from remote. While it can provoke the most intensive experience for learners, to be close to an experiment and really watch the whole process, there are some serious reasons against it. ....

.... approaches have to deal with large response times in large scaled conferences due to the distributed handling of the request, e.g. using quorum based approaches [14] An approach to provide floor control in the Internet as an extension to existing MBone tools is proposed by Malpani and Rowe in [13] using a centralized architecture. Since the approach only maintains a speakers list in a conference, the large response time of the system is not a critical issue. However, this lack of efficiency is not acceptable for generic floor control services. Dommel [3] proposes group coordination in a ....

....service therefore consists of two parts: a robust floor control, and . event management and state repair. Both parts are described in more detail in the following sections. 6.2. 1 Robust Floor Control A significant number of approaches exists to realize floor control for distributed media [32,14,53]. While the main concepts of these approaches are generally usable to support local lag based consistency, there are some caveats that require further consideration. Most important is the robustness of the floor control mechanism. Since the floor control will be used to identify the participant ....

Floor control as provided in the herewith presented interaction control architecture is similar to the concepts evolved by the MBONE questionboard (qb) [14]. While qb provides moderated sessions where the floor is granted by the moderator as well, it limits its application due to the following reasons: Qb is designed for the MBONE.By that it relies on the conference bus [15] as designed for the MBONE tools. For proper operation, the MBONE tools ....

Another set of tools focus on providing services to the end user. The Question Board(qb)[16] provides an interface for remote students to ask questions of the instructor during a dc webcast. The Lecture Browser[17] provides remote students with a synchronized view of classroom materials such as video and slides. Finally, the Georgia Tech eClass[18] focuses on providing students with ....

Finally, an audience management system is needed to provide floor control and device sharing mechanisms[5, 3, 7]. Archival Retrieval. The final function of the digital classroom is to support the archival of multimedia information for later review. Students in a standard course may want to review the lectures at a later time, e.g. before an exam. In addition, a lecture given by an expert may be reviewed ....

A special form of moderator control was developed to support Mbone videoconferences with hundreds of remote participants [8]. Other papers recommend providing users with multiple floor control mechanisms, since different mechanisms might be appropriate for different kinds of meetings and software [6] 5] but most of the recommendations appear to be based on intuition rather than studies or real data.

Later systems such as Tivoli[19] We Met[25] and Dolphin[24] were extended to support remote meetings. More recently, MBone tools, such as wb[7] vic[15] and qb[13] 1 have been used by many people to hold multimedia teleconferences over the Internet. These previous systems typically provide a number of tools to support different phases of meetings, such as those for group drawing and voting.

....Floor control: The current set of MBone tools do not provide any mechanism for controlling access to the floor in a multi party conference. This is especially important in a large scale conference to limit the number of users that can have simultaneous access to the floor. The questionboard tool [M97] developed at UC Berkeley investigated the problem of floor control, but 3 it does not provide any mechanism for the rest of the tools to enforce the floor control policies. In MASH, we have developed a floor control agent which is used to coordinate the floor in the conference; the floor ....

Separation of policy and mechanism is also recommended as a key requirement. The Question Board tool [M97], developed as part of the Continuous Media Toolkit [R ] was an effort at filling the void in MBone lectures for an easy way for remote participants to interact with the speaker. The questionboard tool implements floor control for a single moderator session. A lot of our ideas were developed from ....

In order to allow a group of receivers to perform control actions on the data binding, a floor control policy [16] should be introduced. Transmitter subsystem is responsible of the reading process and the enforcement (by using the RTP timestamps) of timing constraints upon the media streams to fulfil the requirements of the multimedia presentation. In addition, it responds to commands (e.g. play, pause) from ....
