Setting the PIDs
To decode and display the input MPEG-2 TS signal, you must set the video signal and audio
signal PIDs. This section explains how to set the PIDs.
6.1.1
Semiautomatic PID Selection
You can set the PID of the signal to be decoded automatically or manually.
To
automatically set the PID of the signal to be decoded, press F•1 to set SEMIAUTO to
ON. If you switch SEMIAUTO off, you have to manually set the PID of the signal to be
decoded.
• Procedure
SYS
→ F•1 UNIT SETUP→ F•1 to F•4 SETUP (select the unit number that corresponds to
the slot that the LV 58SER04 is installed in)
→ F•1 SEMIAUTO
:
ON / OFF
Automatic PID selection follows this process:
1 The LV 58SER04 searches the PAT for PMT PIDs and sets the program of the first
listed PMT PID as the program to be decoded.
2 Referring to the PMT of the PID set in step 1, the LV 58SER04 searches for video
and audio PIDs. If even one decodable video or audio PID is listed in the PMT, it will
be set as the PID of the stream to be decoded.
3 If there are no video or audio PID listed in the PMT, the LV 58SER04 will set the PID
of the PMT listed next in the PAT as the decode program and repeat step 2.
4 Decoding will not take place if the LV 58SER04 reaches the end of the PAT without
finding a PID to decode.
You can manually set the PID in the MPEG-2 TS to be decoded even when
semiautomatic PID selection is enabled. When the automatically set PID does not match
that of the stream that you want to decode, you can select a PID manually while leaving
the semiautomatic PID selection feature enabled. In this case, once the PID being
decoded from the MPEG-2 TS is no longer detected, the LV 58SER04 will automatically
resume searching for the PID.
Automatically selected PIDs are displayed next to
“V:” and “A:” at the top of the screen.
They are also displayed in
F•2 PMT PID, F•3 VIDEO PID SEL, and F•4 AUDIO PID SEL.
The selected video PID is displayed in green and the selected audio PID is displayed in
light blue.
The PIDs for the audio and video streams that the LV 58SER04 decodes must be listed
on the same PMT. You cannot set separate PMTs for audio and video.
• Quick PID Selection
There is a quick and easy way to select which stream to decode when an MPEG-2 TS
contains multiple video and audio streams, and semiautomatic PID selection is on.
To select the PID of the stream to be decoded, use the A and B keys. Pressing the
will select the PMT PID that is listed in the PAT after the PMT PID that is currently
key
selected. Pressing the A key will select the PMT PID that is listed in the PAT before the
PMT PID that is currently selected.
