Hi :
I have implemented "Simple Roll-up Style Captions" though deckLink SDI device with API version: 10.9.7.
But the monitor didn't clean the text in the current row when I encoder "HCR "cmd to 708CCPkt, which is not conformable with the section 7.1.4.1 in spec of ANSI-CTA-708-E. "Horizontal Carriage Return (HCR) moves the current entry point to the beginning of the current row without row increment or decrement. It shall erase all text on the row."
Does decklink didn't support "HCR", or I made a misunderstood with "HCR"?
If Decklink didn't support "HCR", does a newer API version will support that, or any other method to achieve that?
any suggestion will be grateful.
