Recording from HDMI, is it possible?
Hello All,
From what I have read and the like, HDMI is supposed to be a "secure" connection that does not allow recording. My experience so far bears this out. I have a Viewer Assist Satellite Television system, the satellite dish, the LNB, and the set top box. That said box is a UEC device, actually a custom Linux box with an infrared remote control for the choice of channel and the like. It has the outputs for component signal to the TV, and HDMI. I used to use it with an old style tube TV, to good effect, but it is now connected to a reasonable LED TV that has the option to record to USB, but will not do so for HDMI input.
Is there any way to subvert that, with a PC in the middle, is it even possible to put a HDMI signal into a PC, or is the PC out to a monitor only? Regards, Mark Trickett

HDMI on its own isn't, HDCP is the encryption standard, but yes, anything that displays commercial content is likely encrypted. The old HDCP1 is completely broken, as far as I'm aware HDCP2 (used for 4k video) isn't.

Devices that will (usually as a side affect) strip HDCP do exist, not sure how legal such things are in Australia, but they're easy enough to get.
Hi I think there are devices the strip/can record hdcp. These are usually used for recording gameplay directly off Xbox and PlayStation. If you are looking for one that is where I would start. Gordon.

apocryphally (from early versions of HDMI) there are HDMI splitters with the authentication in the splitter and two feeds for your use On 04/06/18 20:46, Mark Trickett via luv-main wrote:
