Channel Interface
6.3.8.1 Transport MPEG-1 Audio
Error Check Point: Start codes, header data, and packet data
Description: If the ERRORn signal is asserted during the start code, the
Preparser skips the whole packet and resynchronizes to the next start code.
If there are syntax errors during the header data, the Packet Error
Interrupt bit is set, INTRn is asserted if the interrupt is not masked, and
the remainder of the packet after the error is skipped.
If the ERRORn signal is asserted during packet data, the Packet Error
Interrupt bit is set, INTRn is asserted if the interrupt is not masked, and
the data in error is stored anyway.
6.3.8.2 Transport MPEG-2 Audio
Error Check Point: Start codes and packet data
Description: If the ERRORn signal is asserted during the start code, the
whole packet is skipped and the Preparser resynchronizes to the next
start code.
If the ERRORn signal is asserted during packet data, the Packet Error
Interrupt bit is set, INTRn is asserted if the interrupt is not masked, and
the data in error is stored anyway.
6.3.8.3 Transport MPEG-1 Video
Error Check Point: Start codes, header data, and packet data
Description: If the ERRORn signal is asserted during the start code, the
whole packet is skipped and the preparser resynchronizes to the next
start code.
If there are syntax errors during the header data, the Packet Error
Interrupt bit is set, INTRn is asserted if the interrupt is not masked, the
remainder of the packet after the error is skipped, and the Preparser
resynchronizes to the next start code.
If the ERRORn signal is asserted during the packet data, the Packet
Error Interrupt bit is set, INTRn is asserted if the interrupt is not masked,
and sequence error start codes (0x0000.01B4) are substituted for the
errored data.
