    Multi-Media on Thin Clients over RDP

    The "web" is full of anouncements of new thin client technologies promising to deliver higher performance. All these new and not so new technologies move the video "rendering" either towards the server or towards the client. Its interesting that new technologies diverge on this single key point !

    There is also the consideration that faster rendering requires more resources, this can be in the shape of custom hardware (Asics), generic hardware (extra graphics controllers), or hardware vitualised in software (beefier servers).

    There is also the consideration of bandwidth. Some of the new technologies, for example RemoteFX are specifically not proposed for WAN delpoyment.

    Below is a link to a video showing what you can expect with a simple RDP connection between a low cost thin client and W2008r2 server.

    There is no doubt various newer technologies can provide faster graphics, but when the big picture is considered (cost, complexity, upgradeabilty, supportability, futureproofing etc) - "simple" RDP has an important role to offer !

    Absolutly. Ultimatly, I'd love to have entirely web-based thin clients that just run a web browser with plugins and nothing else. At the moment, though, schools need to keep supporting various Windows-based applications, so you wind up having a Remote Desktop Services machine for clients to connect to to run Windows-based software. At the moment, if you want a thin client with both a web browser and an RDP client you either use Linux (which lets us use a capable but increasingly older version of RDP) or a cut down version of Windows (I think we're still waiting for Windows-7-for-thin-clients, aren't we?). Do you have any devices (or are you planning any) that run an up-to-date web browser alongside your RDP client?

    Glad you put that video up. The M80f is extremely capable even without any fancy and expensive backend add ons (citrix / remotefx etc).

    Basically the M80f and a Win2008 terminal server will do most things apart from full screen video playback and sound/video editing. This is a super cheap and excellent value way to deliver desktops to a large percentage of the school. TCO is about as low as you can get via this method.

    For deprtments that require more such as DT/ART/Music/IT you could use fat clients or virtual desktops and take the higher TCO on the chin.

    .

    ...the aim of Zero Clients is to keep the client as thin as possible - so pushing as much work as possible back onto the server. Using the centralised server browser has many benefits (only one AV/content filter to manage, one browser keep updated, less hardware in client etc). So to answer your question, this is not something we expect to offer in the near future.

    one thing i'm interested in finding out about with thin clients is "other" usb device support. We use Lego Wedo and NXT, along with webcams for animation and flip cameras and never seem to get a clear answer if we would be able to use these with a thin client.
