Hello everyone,

As I'm new to this forum I want to start by introducing me.
I am a Software developer. I am in last semester of University and am doing a project that will be evaluated and will decide whether I successfully pass university or not.

Now my task is to build an EPG and Teletext decoder.
Now I have already don the EPG part and have done all the necessary steps to get to the Teletext packets.
Now I am buffering the packets and trying to get them into the right order.

The channel I am extracting the stream from is sending the Teletext data in Serial mode.
So I read the new page number every time I get a x0 packet and for all the upcoming packets with the same magazine number the contained characters should go to the same page until a new x0 packet defines a new page.

Now the problem is that my magazines and pages are ordered in the correct way but the rows aren't in the correct pages to which they belong.

Now I didn't find any other property to be aware of other than Magazine number, page number which is set by the x0 packet and row number which is actually the packet number.

So am I missing something, or does anyone maybe know what I am doing wrong or has had the same issue?

Thank you
