The RoundTable Microsoft Office is a very fresh system of the videoconferencia that offers the panoramic visions 360° driven by its 5 incorporated cameras. Microsoft sent a system to me of RoundTable for the revision. I calculated that I also can install it in one of the conference halls of TMC of two to have some panoramas of test “of the real world”. After covering in several cables, including a cable of the USB to the PC of the host, then I installed to alive client of software beta of meeting 2007 (LM 2007) of the Microsoft Office, that was designed to handle the panoramic cameras of 360° of the RoundTable. I must need that Microsoft is offering a model received for the alive meeting a 2007 of the Microsoft Office as well as solution of CPE (equipment of the premise of the client), that is to say the communication server of office 2007 (OCS 2007). The RoundTable can work with anyone. Nevertheless, I in line proved with an account beta of the alive meeting of the Microsoft Office.
The RoundTable really installs two devices of the camera of the USB. The first one is the active loudspeaker that uses the 6 microphones of the RoundTable to locate where in the quarter it is the active loudspeaker and later to focus one of the 5 cameras on that person. I suspect that it can use really 2 cameras to be centered in a person, since it appears whenever the loudspeaker “is centered” that would probably at least require 2 images of the camera and then the images “hold a concealed knife” meetings, processing, and later transmitted on the cable of the USB. The second device of the camera of the USB is the panoramic camera that combines the 5 images of the camera in a single panoramic image.
Later, I initiated an alive session of the meeting in the conference hall and again went to my writing-desk to assemble the meeting. Unbeknownst to me, for the moment at which it obtained to my writing-desk, the members of the equipment of the sales of some TMC walked in the conference hall to begin a meeting. When I sent to my client 2007 of the LM that I saw Anthony Graffeo, one of the personnel of the TMC sales that watch fixedly at the right in one of the 5 located triangular mirrors hardly on the cameras. I directed on the conference hall of deciros that could see and hear everything that ignited. After giving a brief partial version of program, Anthony it said, “that the thing of frickin is impressive”. Oí similar commentaries of the other TMCers on the next days - including “that thing she is fresh” and the “ululación! Which is that one”
During my tests with the meeting 2007 live on the office, could see the conference hall finds out in the panoramic vision. The other vision video is the “active loudspeaker” and would change to quienquiera spoke. She was really absolutely exact and amazingly fast. When I proved it with rich Tehrani, Joe Fabiano, Mike Genaro, and Dave Rodriguez, all we took the returns that spoke and the opinion of the camera would change almost immediately.
Total, the quality video was excellent, very smooth. I later tested more with as soon as me in the conference hall. I tried to trampear the cameras fitting to pressure the fingers on the microphone and the video would not change. I calculated that it must use a combination of signals audio and video to determine the active loudspeaker. A fast look in the manual reveals, “to avoid to change to a source heals nonhuman, the functions of the video to attend to determine if the detected sound is coming from an assistant or certain a other source.” Contesta that question!
Underneath it is a partial version of sparkle program that demonstrates the active functionality of the loudspeaker. When I worked this test, I did it and I finish to me of way around the conference hall whereas it continued to speak. I will do 2do video with several to TMCers companion if I can obtain to some volunteers. This would demonstrate better the active characteristic of the loudspeaker. Also, the video that I registered appears much more unequal that he was really alive. Part of that is because the study of Camtasia to capture the audio screen was my first time using and, so I only made it fix to 15fps (not 30fps). Secondly, the PC that was ignited recording is not greatest, so I am safe that Camtasia jumped some marks video since the processor was taxed. Nevertheless, this video gives a good sensation you for the active functionality of the loudspeaker. If you wish a version of the great-resolution, to chascar here.

The base has touch-screen of the LCD that serves like dialpad and to form several options. Dialpad external is available also, but I did not obtain one with my unit, so nonsafe if that is an additional option. Dialpad of touch-screen of the LCD looks like quite good I. The physical bellboys also exist to increase/volume of the loudspeaker of the diminution, a button video audio/de the dumb stop, button of sparkle, hook with. /desc., and a button of the information. There is also a socket of the isolation that is going upon the unit to block the cameras and to avoid that any person sees the conference hall.
Although Microsoft RoundTable was designed for alive meeting 2007 of the office and OCS 2007, since it is simply 2 separated devices of the camera of the USB in the one in charge of device, I calculated that it would work more likely with the other videoconferencia, audioconferencing, or software of VoIP. I ignited so upon Skype in the PC of the conference hall and entered the magical video. I tried the panoramic device first, but everything that was exhibited was a black screen. Then I changed it device to the active of the camera of the USB of the loudspeaker and worked. I made a call of Skype of the test to Microsoft Roundtable, again with some TMC'ers companion and the active functionality of the worked loudspeaker in the same way that in Skype. Obvious, it is the hardware of RoundTable that makes the commutation and not the LM video 2007. Also, it could use the way video of the “complete screen” of Skype and had hi-res video extremely with very fast tariffs of the frame. Here he is screenshot of Skype in the action that sees the video of RoundTable:
Microsoft designed RoundTable to equal the light levels that varied when a portion of the conference hall is darker than another one. In fact, the conference hall of TMC has light of the sun coming in the window and I noticed that the RoundTable could make a work quite good that equaled the light through fourth whole number.
Microsoft RoundTable offers a RJ11 (telephone) and a cat RJ45 (network). Wire RJ11 lets to you connect with a line of the PSTN and use the RoundTable like speakerphone high-end of the conference hall. The RoundTable lets to you put calls salient, answers an incoming call, leads a videoconferencia with audio of the microphones or a session of the video-only without audio of the microphones. In the way of the video-only you can use the line of the PSTN or still your telephone of the cell for the audio portion.
I have taste of the aesthetic design of Microsoft RoundTable. It is a device that watches fresh. It remembers the foreign spaceships to me in the war of wells of H.G of the film of worlds (original film 1953, it passage of Tom does not remake). Comparar for! Both have “eyes” and both have a connected long neck with the main base.
Interesting, the RoundTable directly does not point its 5 cameras at you. According to the mentioned thing previously, it uses the triangular mirrors. I am not safe if this were done because people are relaxed and natural if she does not think a camera is watching fixedly at the right behind she or if it were simply for the aesthetic design that Microsoft chose to use the mirrors. I made a certain investigation on history of the RoundTable and discovered previously the Ringcam was called you. During the investigation of Microsoft, they had some interesting versions “beta” before the final RoundTable, including these two down. Note how both models directly indicate cameras towards outside. I definitively prefer the less annoying version of the “mirror” in the model of the production.
Interesting in an article of the pdf of the investigation of Microsoft it speaks of the space equalization of the head-size. That is to say, making sure of each one main is equally great in the videoconferencia although that a person is future of the camera. The article has several diagrams and complex formulas of trigonometry (sinned and the functions of Roman lettuce) that bring the High secondary School behind. The article indicates the following one: In the past some years, there have been many of interest in the use of the omnidirectional cameras for the recording video of the communication and the meeting. Whereas a panoramic vision is able to capture the face of each participant, a disadvantage is that the sizes of the image of people around the meeting table are not uniform of size due to the distances that vary to the camera. Picture 1 demonstrates an image of the panorama of 360 degrees of a quarter of meeting. The size of the table is the feet 10x5. The person in means of the image appears very small compared the other two people because he is more far from the camera.
This has two consequences. First, it is difficult that the remote participants see some faces, thus negatively affecting the experience video of the communication. Secondly, it is a loss of width of band of the space and the network of the screen because many of the pixels are used at heart in time in of the participants of the meeting. Then the technology of sensor of the image advances quickly, is possible to design (more than 2000 horizontal pixels) omnidirectional video cameras of cheap hi-res. But due to the width of band of the network and to the space of the screen of the user, only one small-classified image can be sent to the clients. Therefore how to use with effectiveness the pixels one has become a critical problem in improving the experience video of the communication.
Space-vary-to uniform the functions of the escalamiento (SVU) they have seted out to treat this problem. A function of the escalamiento of SVU bends an image of the panorama to equal the main sizes of people without creating discontinuities. Higo 2 demonstrates the result after the equalization of the head-size.
Note how the individual in the white shirt is greater after the equalization of the head-size. Unfortunately, it does not appear that the RoundTable that I am proving incorporates the equalization of the head-size, since no of the heads in the conference hall appeared to be even. To conjecture that my head (and ego) will have to continue for being greatest. Leo for above in the this greater one and according to this article of Microsoft, RoundTable “uses visual signals to establish clearly, to enlarge and to accentuate the face of the loudspeaker”. It sounds so as it has this characteristic. I will have to prove the this future one.
Conclusion
All in all, made an impression to me enough with Microsoft RoundTable. With its panoramic opinion and functionality video of the commutation of the active speaker, almost you feel as if you are there in the conference hall. Desire the panoramic device of the camera of the USB worked in other uses in addition to LM 2007 and OCS 2007, but at least the active video of the loudspeaker works. Although it is not sent for the general availability, hopes that Microsoft Wendish RoundTable to by minor for around $3,000 that puts this in the category of the systems high-end of the videoconferencia. Nevertheless, with fuel costs and other costs of route, a system of high quality, high-end of the videoconferencia can pay itself very quickly.
