EXCEPTION CONDITION
36
SAA6752HS continues encoding; note 1.
SAA6752HS continues encoding but outputs audio ES
packets only; SAA6752HS will resynchronize if video
input is recommenced; notes 2 to 4.
SAA6752HS continues but frames may be lost during
the event.
If enabled, the SAA6752HS PLL will auto-switch to
Clock mode 1 or 3 as programmed.
Stream output stops or corrupted data will be
delivered; reset or forced reconfigure needed to
recover.
Ratio between number of generated audio frames and
number of generated video frames is not nominal; time
stamps remain correct; note 5.
SAA6752HS continues encoding but will not include
audio packets.
SAA6752HS continues encoding but will not include
audio packets.
SAA6752HS continues operation.
SAA6752HS continues operation.
SAA6752HS ignores the I
SAA6752HS will go to Idle mode if time-out is enabled
or stop operating if time-out is disabled; in case of the
later a forced reconfigure is recommended.
SAA6752HS continues encoding but outputs video ES
packets only; transition to STOP needed to recover.
