A Guide to Chaptering on Samsung TVs

[Gus]

For advanced users who want to create/edit their own .MTA files, here is a quick guide...

The .MTA files are basic text files with XML formatting. They can be edited with any regular text editor. I would suggest Notepad however this tends to do funny things with filenames and adds .TXT whenever it likes and don't get me started on CR/LF :-)
So i would recommend Notepad2 as a decent text editor, you can download it at http://www.flos-freeware.ch/notepad2.html

After you load Notepad2 and the .MTA file. You will see each chapter data between the tags:

<ChapterSegment>
 ...
</ChapterSegment>

The chapter time stamps are in the <MediaTime> tags. For example:

<MediaTime timePoint="900"/>

The number in quotes is the seconds timeline, in this example a chapter point at minute 15. You will then see each chapter point increase by 900 seconds.

The thumbnail images are in the <InlineMedia> tags. For example:

<InlineMedia>/9j/4AAQSk.........//Z</InlineMedia>

The data inside the tags are JPG files with base64 encoding and all have a basic black image at the moment.
To decode base64 --> JPG. Visit this site: http://www.opinionatedgeek.com/dotne.../base64decode/
Or to make your own thumbnails, you will need to encode a standard JPG file to base64.
To encode JPG --> base64. Visit this site: http://www.opinionatedgeek.com/dotne.../base64encode/

The native resolution of a Chapter Thumbnail is 110x80.

To add/remove your own entire chapter points, just remove or replicate the full tag contents of:

<ChapterSegment>
 ...
</ChapterSegment>

If you get stuck, just post a question here.

Cheers
