I would like to inspect the audio data islands of a 1280x720 progressive scan 60 Hz HDMI signal. I simply want to view these data islands to see exactly when audio data begins to be transported in the data islands relative to another signal (an analog audio signal generated by an HDMI audio DAC. I can convert this to a digital one if it makes things easier). What specifications would be required of a logic analyzer to do this?
Related: is there a hardware TMDS receiver/decoder that I should be using or is decoding something I can do in software/with the logic analyzer? I do not want to reconstruct the audio signal, so I am not interested in an HDMI receiver that regenerates the audio clock and provides an audio stream. I am not concerned about noise, so I don't expect to need to make use of the balanced signals; if there is a bit of error in the readings from time to time that should be fine for my purposes.
