Horizontal and vertical blanking will be unchanged from regular SDI output mode.
As shown above, four RAW pixels will be packed into three SDI pixels, so each Ultra HD line will
contain 3840 x 4/3 = 5120 RAW pixels and the entire RAW frame will be carried in the first 1658
lines of the 2160 active SDI lines. The remainder of the pixels in the SDI frame will be set to
0x100 for both Y and C.
The RAW SDI frame should be captured as uncompressed 422 data and unpacked according to
the table above.
Recording the RAW signal
The data can be recorded as an uncompressed 10-bit YUV recording using a 6G-SDI capable
product, such as one of the following:
‚ UltraStudio 4K
‚ UltraStudio 4K Extreme 3
‚ DeckLink 8K Pro
‚ DeckLink 4K Extreme 12G
‚ DeckLink Studio 4K
‚ DeckLink SDI 4K
‚ DeckLink Mini Recorder 4K
Unpacking the RAW data:
Once you have a QuickTime recording of the RAW data, you will need to unpack the signal to
perform your own debayering of the image data from the sensor.
