ILRS – Technology for Education Business


seminar hallSome of the most common issues with any lecture / presentation / training session is lights – when you reduce light, you won’t be able to see the presenter, on the other hand when you increase it, and you won’t be able to see the slideware. Thus many organizations started the concept of recording the session, so that it could be referred later as well.

Understanding the session

Recording is a lecture / presentation / training session etc. is no surveillance. It’s not for monitoring, but for academics. We record it for academics purposes only. A good training session could always be referred to for brushing up the knowledge acquired, for revision, for research, for training another set of trainees, if the lecturer is unavailable, for distance education, there could be many usage. But all that can be done, only if it is recorded well.

Before we get on to recording a session,     we      first      need     to understand the subject and the set up. If we have a generalized look, what is the most common feature of any training / lecture / classroom/ presentation / seminar?

–      We have a presenter / lecturer / trainer, who imparts the training.

–      We have his content on a slideware to decide the flow of the presentation / or a white board / black board, where he writes and draws to explain his concepts.

–      And we have some audience / students / trainees.

Also important to note here is that the rooms is divided in two parts, wherein the presenter and the slideware are facing the audience and vice versa.

Recording the session

layout_lecture_hall_circleWhile we take a decision on recording, it is very important to understand what is to be recorded, what is to be focused upon and what can be omitted?

It is obvious that the presenter and the presentation has be focused upon, but the nature of both is to be understood well. For example, the presentation would be static at one location only, but the presenter would not be static. He would be moving. His gestures, his dialect, and his expressions – all are important in developing an understanding upon the concepts he is explaining.

Similarly, most of the sessions are kept interactive, thus the audience may ask a question in between. Questions are good, since one guys question can explain the concept better to another guy too. But for everyone to understand from one guys queries, it is very important that people get to know the complete question and its answer too. Thus focusing on the audience is also very important for recording the lecture, keeping FAQ in mind.

To summarize, we have three subjects in three different directions to focus upon. While two of them (audiences & the presentation) are static, the third one (the presenter) would be mobile.

The set up required

the ecosystemNow that we have a better understanding of the setup, we can plan for resources better. As we need to focus on three directions, we need to have three cameras, as one of the subjects in mobile, the camera focusing the subject also has to be mobile. Thus we need to have a tracking device, which’ll be attached to the presenter, so that whenever, wherever he moves, the camera focusing him should also move and maintain the focus. Now depending upon the size of the room, / hall, the presenter might need a microphone as well, so we can have a tracker device with built-in microphone.

Now that we have captured the three directions through camera, we would need a device to put up the presentation too, it could be laptop / desktop / DVD player / projector / speaker system etc. and the display device on which the camera would focus. And finally, we need a device for mixing and editing the feed from

3-4 different sources, into one composite video file format. Yet another mechanism would be required for saving the video files thus created. If it’s on ad-hoc basis, it can be a simple USB storage, but for academic purposes, we need to have a central repository, wherein the lecture video could be sorted and stored like a library on the basis of subject / lecturer / course etc.

Now here it is very important to note that whether ad- hoc or permanent setup, but we can’t expect the presenter to be an AV industry expert that he could log in to the cameras / mixing and editing device etc. to start the session for recording. For him, it should be a simple one press button to get the system going. So a separate one button console for the presenter to start the session would also be a key infrastructure requirement.A series

The ILRS is an Intelligent Lecture Recording Solution, that works upon the above mentioned understanding of the lecture / seminar / presentation requirement. we place three cameras in three different directions, each facing the presenter, the presentation and the audience respectively. The camera focusing upon the presenter has got maneuvering base linked to the tracker device, which is built-in into the presenters microphone. the camera moves along with the movement of the speaker / presenter / lecturer. all the devices are connected to the media manager device, which takes the feed of each camera mixes and edit it into one video file. the video file is then stored in the central repository that can be accessed, as and when desired. the whole system would get started with just one button press from the presenter, when he intends to start the session.

It’s simple, it’s smart and it enables people. so be it a corporate training or a school or a university, the best way to record and produce the lecture sessions is – ILRS.
