    Hello,

    I’m wondering if it is possible to create a WSS decoder using the video experimenter? The standard can be found here

    http://www.etsi.org/deliver/etsi_en/300200_300299/300294/01.04.01_60/en_300294v010401p.pdf

    I would like to read the 14 WSS status bits and print them out on the screen. I assume the 5MHz WSS signal (divided by 6 since it uses 6 clock periods per bit ?) is too fast for the arduino. However, since the WSS signal is stable over a longer period of time, is it possible to decode the different bits using different frames?

    For example
    – take 2 samples to decode bit1 in frame1
    – take 2 samples to decode bit2 in frame2
    – etc.

    So in total it would take 14 frames to decode all the WSS bits (or even 28, if we take 1 sample per frame). Or is even in this case the arduino not fast enough to sample?

    Thanks in advance
