Can someone explain the REJECTED option in plain English?

[Mackerelq]

I have been authoring VCDs for a short time now. I have been able to ingest approximately 99% of the concepts, but one still lingers: The Rejected option. Here is what HVR has to say on this subject in the VCDImager manual:

Rejected:

Attribute controlling, whether item is not listed, i.e. rejected, in the lot. Lists which are not rejected may be- if supported by the playing device- selectable by user input of the automatically assigned List ID Number. It is recommended to enable the rejected property for but the very first PBC list, in order to make the unreferenced item check work better. The first PBC Item must not be rejected.

W.T.F.?

That makes absolutely no sense to me.

Can someone explain this concept in simple concise language?

Thanking you ahead of time.

alright, I admit this one isn't one of my best explainations...

lemme try it a bit simpler,

there's something like a LOT, a table which holds on one side the list id number, and on the other side the file offset address;

each pbc 'node' (selection list, play list or endlist) has a unique list id number.

usually you don't care at all about the list id number of a pbc node; but the specification mentions the (optional) ability to select a pbc node directly by its list id number;

in order to make a list id number unavailable to the user, actually this means that the user won't be able to jump directly to that node; you can declare that node to be 'rejected', that way it will be marked in the LOT being 'rejected'...

now you might think, that you don't care at all, if the nodes are reachable directly by LID; that's maybe right so, but there's another thing this 'reject' is used for in vcdimager:

I've implemented a graph traversal check in the pbc graph, in order to detect nodes which aren't reachable starting from non-rejected nodes...

that way vcdimager can catch authoring 'bugs' in the pbc structure...

hope it's clearer now... btw, you are invited to send me a better paragraph to explain this concept better...

Thank you for responding to my post. I apologize if I seemed offensive, I was just severely frustrated.

So, basically what you are saying is that marking a PBC node 'rejected' makes it unavailable to jump directly to it by its LID, right?

If so, this spawns two questions.

1. How do you jump directly to a PBC node by its LID? The only way I know to jump to a selection or playlist is by the standard PBC controls (<<,>>,up, dn, return, and 0-9).

2. Does enabling the 'Rejected' flag disable jumping to a selection or playlist via the PBC controls or just by the List ID?

Thanks again.

ps. I love VCDImager.
Thank you Thank you Thank you Thank you Thank you!
