Thank you for the reply.
The material is from a satellite raw feed rather than a consumer service channel so it is not encrypted. However, I take your point about the HDCP possibly being applied all the time to the HDMI output. I can get the raw feed directly into a Viewcast Osprey capture card at SD resolution with component video inputs but I thought that I would try to upscale to HD using the DVDO Edge and input the HD content into the Decklink card via HDMI.
Unfortunately, the only video processor I have is the DVDO Edge with HDMI output only, an alternative VP with either SDI HD output or component HD output might be a better option if there are any suitable VP candidates for my limited budget, possibly an older model?
Also, I might try an HDFury in the line just to get rid of the HDCP issue if it is present.
