[QUOTE="misterd, post: 154535, member: 19503"] Hi all, currently I don't have much time to complete the patch. Perhaps next month I have more time to complete it. I also realised that I have to update the old TV Engine too, because both engines use some code in MP that I have to modify for my patch. For the problem of the rotation speed I see only one really good solution. But this solution is very complicated and a lot of work, because I have to rewrite many parts of the code and change the whole handling. All other solution I have evaluated doesn't fix all problems. My solution would be to store the whole teletext data in the ts files and write a special directshow filter that display the teletxt page with VMR9. Therefor the filters must be modified to store the data in the ts files and I think that the streaming engine must also be changed. Any help for this is really appreciated, but as mentioned above I don't have much time this month. I should mention that you need C++ experience for the filters, which isn't my preferred programming language. [USER=51953]zmrcic[/USER]: The telexted pages are sent in a binary form. Then you have to parse this data stream and create a picture of this. This is the way MP is doing this. There exists a standard for teletext transmissions from ETSI. If you want to create an own teletext page than you have to create such a binary stream. But I don't who this can be done. Regards, MisterD [/QUOTE]
