3.6 Program Segment Descriptors (PSD) Section
=============================================
Here is part of sample output from the test PAL SVCD that can be found
from:
<http://www.vcdimager.org/pub/vcdimager/examples/test_svcd/test_svcd_pal.zip>
SVCD/PSD.SVD
PSD[00] (LID[1] @0x0000): play list descriptor
NOI: 2 | LID#: 1 (rejected: no)
prev: disabled | next: LID[2] @0x0003 | return: disabled
playtime: 0/15s | wait: 0s | autowait: 0s
play-item[0]: SEGMENT[8] (0x03ef)
play-item[1]: SEGMENT[7] (0x03ee)
The first line SVCD/PSD.SVD again is the file entry that we are
reading. Since the CD image is in the SVCD format have that particular
name. If the CD image were in VCD 1.1 or VCD 2.0 format the line would
read VCD/PSD.VCD.
Above NOI shows that there are two play-item entries, the individual
entries are given below. We also see that this item is not "rejected"
and thus could be accessed directly from a player.
The corresponding XML text for the above output is:
<playlist id="playlist-01">
<next ref="playlist-02"/>
<wait>0</wait>
<autowait>0</autowait>
<play-item ref="segment-0007"/>
<play-item ref="segment-0006"/>
</playlist>
Some of the tag names like "play-item," "wait, and "autowait" given
above match what are in the XML description. Although, you won't find
"next," "prev" or "return" listed, the tag names are also the same. In
the XML you are free to omit values and you will get default values put
in; in 'vcd-info' you see what has been filled in.
Below is another excerpt from that file.
