Showing from one machine on another.

[SYNACK]

Presumably "Windows Media Server Services" requires some kind of Windows server. I don't have many of these available. Has anyone actually done this, if so what happens in the case of multiple "senders"?

That I am not sure of but the teacher would have to run the program and it would quit when they logged off so that should kill it at the end of the lesson. As it is only one stream it should not be to much of a load on the server because it does not need to do any encoding just rebroadcast it.

 

The obvious problems here are

a) the user can exit media player or easily make it display a different media.

b) AFAIK there is no way for media player to only go into full screen mode when something is being sent to it.

 

a) set it as the shell application for that logon with GPO (local or domain) so that it runs and when it is closed it logs out Managing a Custom Shell via Active Directory

b) Control Windows Media Player Behaviour with Command Line Parameters » My Digital Life

wmplayer “c:\filename.wmv” /fullscreen

– Play the specified file in full-screen mode. The path and file name of the content to play must be specified.

* From memory Lanschool has a mode where you (the student) can select what teaching unit (aka teachers computer) you want to listen to which is handy if they want to change classrooms and such.

If the student could see well enough to operate such a system they might well not need it in the first place. Being able to just look at the board

I might be off the mark here but would the teacher licence on the pupils laptop not fulfill the OP's requirement. The pupil can then look at any screen of any teacher for £199 as all the clients are free. From a security standpoint ABTutor is highly configurable in terms of what the pupil may do.

 

again, just a guess. but i'm assuming there's more than one teacher machine where the screen is to be broadcast. hence the multiple senders.

that sounds like the ideal solution. although i'm sure those little security camera monitoring tv's don't come cheap. when you say a 2.4ghz signal rebroadcaster, are you thinking a generic AV sender. so you'd have vga to s-video/composite from the presentation pc to a sender and then a receiver unit connected to the s-video on a the portable ?

 

2.4G is no good for the following reasons.

a) It is likely mutually interfere with WAPs and other units.

b) Not only will RF propergate some considerable distance within a building it's also possible for the strongest signal in parts of room A to be from room B. (Especially when the transmitter in room A is switched off.)

 

inspite of the tv cost probably still cheaper than an arbitrary number of licenses for classroom mgmt software teacher licenses. just sounds like the OP wants a software solution....but as you say a small delay would be inevitable. and there's still a certain amount of complexity.

 

I don't especially care if it's hardware or software.

Cost is a factor, including people's time. Installing software on individual machines tends to be quite time consuming, especially when these machines are laptops issued to teachers.

By comparison connecting a box to a projector is easy. Just need some which use a wavelength which won't pass through plasterboard, wood, concrete and glass. 940nm fits the requirement rather better than 125mm

No the £199 is for the teacher machine but includes unlimited clients and the tutor control can work from USB memory stick so is highly flexible.

 

Unlimited "clients" is of no use here. It's always going to be a definite small integer

 

The memory stick comment implies that the sending software need not be installed on a machine. However such devices are far too easily lost, mislayed, broken, stolen, etc.

Only if it's possible for a "student" display their machine on the "teacher's" machine without anything needing to be done on that machine and regardless of if another "student" is connected.

two and a half would by 20 teacher licenses (@ 125.00ea) based on their quote pages

 

When you take into account different teachers for each subject as well as cover teachers (both internal and external) the numbers soon add up. Indeed to properly cover all eventualities the number is more or less the entire teaching staff. (Which would be closer to £12,500!) Whilst it's unlikely that a student will wind up being taught by every teacher over their time in the school it's impossible to predict teachers they will have.

It's per teaching console, not per teacher, so say if theres a desktop at the teaching desk.... or do the teaching console on the usb stick.
