Hello,
I'm completely new to electronics and I'm unsure if this is the appropriate place to ask this question. Nevertheless, I would like to understand the following:
I recently read that when you connect a camcorder to a firewire card, the firewire cable functions similarly to a USB cable by transferring data. However, I'm unsure if data and signal are the same thing. In this case, I'm curious to know who actually performs the data conversion: is it the PC or the firewire card? Considering the presence of various "chips" and components on a firewire card, I assume they play a role in this process. If the firewire card handles the conversion, would it be possible to create a small case with a PCIe slot and a battery, allowing us to "capture" the video signal from the PCIe slot?
With this setup, you could connect the PCIe slot to a GoPro and record the incoming video signal.
I'm interested to hear your thoughts on this matter.
Thank you.
P.s. By "connect" I mean internally as a GoPro has no input jack.
