Abstract

Prior to the intermediate host conference, an Intermediate Host Conferencing Module communicates a library of digital objects and the Intermediate Host Conferencing Module to an intermediate host communications device(s). During the conference, the intermediate host-resident Intermediate Host Conferencing Module receives a synchronization command and instructs the intermediate host communications device to communicate a synchronized object with presentation instructions to a downstream participant communications device and to present the synchronized object to the intermediate host communications device. Furthermore, the participant communications devices may communicate a synchronization acknowledgment back to the Intermediate Host Conferencing Module. The synchronization confirmation acknowledges a successful presentation of the synchronized object to the intermediate host communications device and/or to at least one of the downstream participant communications devices.

initializing the conference amongst at least one intermediate host communications device and at least one downstream participant communications device;

prior to the conference,

communicating a library of digital objects to the intermediate host communications device,

communicating an intermediate host conferencing module to the intermediate host communications device; and

during the conference,

communicating a synchronization command from a host communications device to the intermediate host communications device, wherein in response to the synchronization command, the intermediate host conferencing module instructs the intermediate host communications device to present an object from the library of digital objects and to communicate the object to the downstream participant communications device with presentation instructions to the downstream participant communications device to present the object,

communicating the object with the presentation instructions from the intermediate host communications device to the downstream participant communications device, and

communicating the object with the presentation instructions for another downstream participant communications device from the intermediate host communications device to the downstream participant communications device, wherein the downstream participant communications device communicates the object with the presentation instructions to the another downstream participant communications device; and

receiving, at the intermediate host communications device, a synchronization acknowledgment from the at least one downstream participant communications device.

2. The method of claim 1, wherein the intermediate host conferencing module further communicates a conferencing management command to the downstream participant communications device, the conferencing management command comprising at least one of (i) a command to exit the conference, (ii) a command to delay presentment of the conference, (iii) a synchronization override command to access to any object from the library of digital objects, (iv) authority to distribute the object to a non-participant, (v) authority to modify the object, (vi) a command to terminate further communication of the synchronization acknowledgement, and (vii) a command to modify a communication connection of the conference.

3. The method of claim 1, wherein the synchronization acknowledgement confirms a successful presentation of the object to at least one of the intermediate host communications device and the downstream participant communications device.

4. The method of claim 1, further comprising delaying communication of a subsequent synchronization command until the synchronization acknowledgment is received from the intermediate host communications device to the host communications device.

5. The method of claim 1, wherein the synchronization acknowledgment further provides at least one of (i) a request to exit the conference, (ii) a request to delay presentment of the conference, (iii) a request to access to a non-synchronized digital object, (iv) a request for authority to distribute the object to a non-participant of the conference, (v) a request for authority to modify the object, and (vi) a request to terminate further communication of the synchronization acknowledgement.

6. The method of claim 3, further comprising:

ignoring receipt of the synchronization acknowledgment from a selected downstream participant communications device, thus allowing the selected downstream participant communications device to request any object from the intermediate host communications device via the intermediate host conferencing module, such that the requested object is communicated with presentation instructions from the intermediate host communications device to the downstream participant communications device.

7. The method of claim 1, wherein initializing the conference amongst the intermediate host communications device and the downstream participant communications device comprises:

accessing a list of intermediate host communications devices and downstream participant communications devices, and

communicating the list of intermediate host communications devices and downstream participant communications devices to at least one of the intermediate host communications device and the downstream participant communications device.

8. The method of claim 1, wherein initializing the conference amongst the intermediate host communications device and the downstream participant communications device further comprises:

analyzing transmission rates between at least two participant communications devices and between the host communications device and each of the at least two participant communications devices to determine the intermediate host communications device and the downstream participant communications device.

9. The method of claim 1, wherein initializing the conference amongst the intermediate host communications device and the downstream participant communications device further comprises at least one of:

analyzing a cost factor between at least two participant communications devices and another cost factor between the host communications device and each of the at least two participant communications devices to determine the intermediate host communications device and the downstream participant communications device, analyzing a reliability factor between at least two participant communications devices and another reliability factor between the host communications device and each of the at least two participant communications devices to determine the intermediate host communications device and the downstream participant communications device, and analyzing a security factor between at least two participant communications devices and another security factor between the host communications device and each of the at least two participant communications devices to determine the intermediate host communications device and the downstream participant communications device.

10. The method of claim 1, further comprising:

verifying the intermediate host communications device has local access to the library of digital objects, and

verifying an available communications connection between the intermediate host communications device and the downstream participant communications device.

13.
