Why aren't there any PCM video devices? I have seen countless PCM audio devices. Why not use the same for video? Just give it a strong bit-resolution, a low frequency sample rate, and multiple video channels and you will get quality much better than MPEG video. MPEG is data reduction and looks bad on the screen. It may work for 2D video but not for 3D video. I would like to use strong bit-resolution, slow sample rate, multiple channels PCM video for virtual reality.
