PGC STREAM ATTRIBUTES WINDOW

 

DOMAIN: TITLES

 

This window can be opened using the popup menu (mouse right click). In the PGC area of the main window.

 

This window is informative only and when opened, it shows the title domain audio and subpictures attributes stored in the VTS IFO, and some attributes read from the VOBs, like the bitrate.

 

Audio size is estimated in two different ways (indicated at the bottom of the window):

A) If VOB Scan has not been done size is estimated using three data:

- Audio status per PGC. (present/not present) (taken from the IFO)

- Bitrate (taken from the header of the audio stream inside the VOB)

- Length of the PGC. (taken from the IFO)

 

B) If VOB Scan has been done, size is estimated using two data:

- Number of audio packs of this stream detected during scan.

- Length of this PGC and lenght of all the PGCs using this stream. (Info taken from the IFO)

 

Subpictures size is estimated using VOB Scan data and PGC lenghts. If VOB scan has not been done, this info is not available.

 

 

Audio and Subs lists are ordered by track # . In both lists an additional column shows the stream used.

One Audio track can use only one stream per PGC.

One Sub track can use up to 3 streams per PGC in case of 16:9 video (WIde, PanScan and LetterBox) . In the case of 4:3 video only one sub stream is allowed.

  

In audio attributes list, an additional column is listed showing the audio/video delay. (This delay can be different between different PGCs in the same VTS). A negative delay means the audio starts before the video.

 

When replacing title PGCs, VobBlanker checks the coherence between the audio attributes stored in the IFOs and the attributes of the audio streams in replacing title. If they don’t match, VobBlanker asks the user about changing audio attributes stored in the IFOs..
