VBI Frame Output Mode
In VBI frame output mode the TW9903 is generating VBI data all the time (i.e., there is no VBI
active interval). In essence, the TW9903 is acting as an ADC continuously sampling the entire
video signal at the crystal rate. The TW9903 generates HSYNC, VSYNC and FIELD timing signals
in addition to the VBI data, but the DVALID, HACTIVE, and VACTIVE signals are all held high
during VBI frame output operation. The behavior of the HSYNC, VSYNC, and FIELD timing signals
is the same as normal YCbCr 4:2:2 output operation. The HSYNC, VSYNC, and FIELD timing
signals are used by the video processor to detect the beginning of a video frame/field, at which
point it can start to capture a full frame/field of VBI data.
VBI Byte Order
In 8-bit output mode, if VBI Byte Order (Reg0x19[6]) is set to “0”, 8-bit VBI output data have the
following order.
VBI2-VBI1-VBI4-VBI3-VBI6-VBI5-……
Even number VBI data is output at first and odd number VBI data is output next. This function is
useful for Motorola type CPU or similar logic. If VBI Byte Order (0x19[6]) is set to “1”, 8-bit VBI
output data have the following order.
VBI1-VBI2-VBI3-VBI4-VBI5-VBI6-…….
Odd number VBI data is output at first and even number VBI data is output next. This function is
useful for Intel type CPU or similar logic.
In 16-bit output mode, if VBI Byte Order (Reg0x19[6]) is set to “0”, above odd number VBI data is
output on VD[15:8] pins and even number VBI data is output on VD[7:0] pins. If VBI Byte Order
(Reg0x19[6]) is set to “1”, above even number VBI data is output on VD[15:8] pins and odd
number VBI data is output on VD[7:0] pins.
