The TS source can be selected by pressing the Source (F1) key on the Coding (L-1)
screen.
Notes on selecting TS_source
• The receiver is temporary unlocked when TS source (each pattern stored in the
ROM, PN, SPI, ASI) is switched since the coding circuit is reset.
• When the external TS (SPI, ASI) is selected, reception capability is disabled if TS
INPUT alarm lights on the top screen or TS exceeding allowable rate is input.

• TS Source (F2)
Selects the TS input to be used.
PN Pseudo random signal in PN23
ROM Modulates and outputs the video and sound signals stored in
the ROM.
External <SPI> TS input to the SPI connector on the rear panel is used.
External <ASI> TS input to the ASI connector on the rear panel is used.
Internal TS of HDD on DVD is used when the Moving Picture Option
(OP70) is installed.
• Null Packet Filter (F4)
This key is only enabled when the External (i.e., SPI, ASI) is selected. The packet
with 0x1FFF PID is filtered off from the TS applied to the input connector.
Various carrier modulation capabilities can be increased by removing surplus null
packet.
• PCR Update (F5)
Channel coding is performed for the external TS applied.
The PCR should be rewritten to convert the rate. Set this function on in general.
Up to eight PCRs are rewritable for the external TS.
