OUTPUT FORMAT
Output Level
When the output level of the operation mode is NTSC, the content of the output level differs
depending on setup level setting by internal registers.
When the setup level is set, data is output with Black-White as 92.5 IRE.
When the setup level is not set, data is output with Black-White as 100 IRE.
However, the setup level setting above is valid only when NTSC is selected as operation mode,
and setup level does not exist when PAL is selected as the operation mode.
When the contents of 100% luminance order color bar are input to the encoder, the DAC input
level is as follows.
