During the transmission of the video signal, the portion of the stream in-between active video data segments is known as the horizontal blanking interval.
Strictly speaking this entire region is the blanking interval, but this interval also includes the EAV and SAV codes. The remaining bytes of information in a digital blanking interval are filled with values corresponding to the blanking levels of the Cb, Y and Cr signals respectively, and in accordance with the standard multiplex sequence for the stream (CbYCrY..). The blanking levels are as follows:
The sequence in the BLANKING region of the data stream is therefore: 80h, 10h, 80h, 10h.....80h, 10h
For more details on setting the blanking timing values for BT.1120 and/or BT.656 mode, see Section 12.6.3.11.8, DISPC VP Timing Generator and Display Panel Settings.
