WAT-910BD H/W MANUAL
(3)Output Timing for Digital Data
The effective image data is outputs the Luminance Data and Color Difference Data in Y/Cb/Cr=4:2:2 format.
(The output sequence is repeated in the Cb,Y,Cr,Y,… sequence)
Since the WAT-910BD is a monochrome camera, the Cb,Cr data are all 80[h].
The Horizontal Blanking Period (without TRC Code) is Cb,Cr=80[h], Y=10[h], repeated output.
The TRC Code, which is used to set the Efective Pixel Period, is output with every horizontal line.
The TRC Code complies with the ITU-R BT.656 standard, and output the 4 Byte Codes below.
SAV: Start of Active Video [hex]
EAV: End of Active Video [hex]
The 4th Byte of the TRC code (XX) is output according to the Figure below.
*NOTE:
F=0 : during field 1
F=1 : during field 2
V=0 : elsewhere
V=1 : during field blanking
H=0 : in SAV
H=1 : in EAV
P0-P3 : protection bits
Fig.5-11(EIA)/Fig.5-12(CCIR) shows the output timing for 1 line worth of digital data.
Fig.5-13(EIA)/Fig.5-14(CCIR) shows the output timing for 1 frame worth of digital data.
