HDMI RGB
Range HDMI RGB Range selects the output range for HDMI YCbCr. Full allows a range of 0-
255 and SMPTE limits the range to 16 to 235 (see note).
Note: YCbCr luminance (Y) channel data ranges nominally between 16 (black)
and 235 (white). Values outside of this range are typically clamped to the valid
range. This may cause confusion because JPEG JFIF YCbCr values range between 0
and 255. Mixing these values causes video contrast shifts. You can avoid these
shifts if you maintain one range of values throughout your system.
AES/EBU SRC
Mode AESEBU SRC Bypass controls the mode of the audio sample rate converters for AES/
EBU input audio pairs.
In Manual mode, the sample rate converters are enabled manually for each AES pair.
In Auto mode, the system decides how to handle sample rate conversion. Normal
PCM audio passes through the Sample Rate Converters and gets converted, as
appropriate. AES channels in which the non-audio flag is set in the Channel Status
Word are automatically detected and allowed to bypass the Sample Rate
Converters; the signal passes unaltered and the existing data is preserved,

Manual
The signal bypasses the Sample Rate Converters for audio
channels containing a non-audio flag in the Channel Status
Word. If the non-audio flag is not set, the signal passes
normally through the Sample Rate Converters.
The FS2 determines what to do about audio sample rate
conversion on a channel pair-by-pair basis. If a channel pair
is set to On, sample rate conversion is applied to that channel
pair. If a channel pair is set to Bypass, the FS2 leaves
embedded audio as is, bypassing sample rate conversion;
this is useful for Dolby

applications where you do not want sample rate conversion
to occur.
