Hi.

I am about to start a master degree course in Embedded Systems and I have an idea for my individual project. Basically I have an audio and video signal which will be encoded somehow; I would like to send such signal to a portable iOS based device over the LAN and collect from the device an audio signal only, as well as a few "push button" status which will be available on the app interface.

I have never used ARM technology before but I would like to start learning on such project. Having said that, I would be enormously grateful for any of your comments. Is ARM the right tool for that or is it a waste using ARM for such thing? If ARM would be suitable for my project, which processor /development board should I use?

Thank you for your time!

    Hi Alban.

       Thank you for the swift reply! I had to make myself a sandwich as you made me hungry
    What I want to do is a network interface for a door entry system that will stream the audio and video collected at the door station to a portable device. The audio and video signal are available on a twisted pair (per signal) or they might even be embedded together on a pair of stranded wires. I want to develop an app, which will look and feel like an indoor station, and someone is at the door and press the call button the device(s) will ring together with the indoor station(s) installed in the property. The user will need to be able to reply via the portable device to the person outside (that is why I said there will be audio going back to the interface) and open the gate or the garage door (that is what I intended for push-button stuff). The Raspberry Pi you are suggesting seems like could work just fine and also the price is very appealing. I am going to get more detail about the audio and video signal as well as the opening triggers.

    Thanks again! 


    Hi Dsquared,
    ARM processor offering is wide enough for you to find what you need.
    On top of that, ARM Partners build a wide range of SoC with a wealth of features.
    If the signal is already encoded, you don't really need to do much except shift the packets to the network.
    I'm not sure from your description which device is supposed to separate the audio from video signal.

    You probably have heard about the Raspberry Pi evaluation board. It features an ARM11 processor with network connection.
    Thanks to its cheap price, you don't care about its extra features like HD video playback.

    As you can run some Linux distro on it, you can re-use video streaming software and can concentrate on the push button stuff you want.
    Have a look at First Taste of Raspberry Pi...
    You have so many boards that it's like with a big menu, choice is the problem :)

    Cheers,
    Alban
