DEFAULT
SAA6752HS output stream formats for details):
Elementary Stream (ES):
Elementary stream output is possible for audio
or video only encoding.
Packetized Elementary Stream (PES):
DVD-compliant: PES packets have a limited
size and can be easily multiplexed into a DVD
program stream.
TS-compliant: PES packets have an unlimited
size and can be easily multiplexed into a
transport stream.
PES packets containing audio and video
information are flagged with an audio/video
signal pin. The audio/video polarity of the
signal pin is programmable.
Program Stream (PS):
A DVD-compliant program stream is generated,
but no navigation packs are inserted.
Transport Stream (TS):
A transport stream is generated.
Pack stream is a special not MPEG-compliant
mode. The MPEG buffer model is not used.
VES + AES mode allows VES output from the
output port at the same time as an SPDIF
formatted AES is output from the 2nd I
port. For this mode subaddress 92H must be
set to zero.
Maximum target bit rate of the system stream
in kbit/s (= 1000 bit/s) and must be set if TS or
PS or pack stream modes are selected. It is
ignored if ES or PES streams are selected.
Number of flushing bytes appended to the
stream after a stop.
