Enhancement: XDS support?

[JasonTable]

So i had this idea of maybe supporting https://en.wikipedia.org/wiki/Extended_Data_Services feature that tv stations used to use for program information. One thing that would be especially cool is supporting the "autoclock" system so that any device that supports it can have the time set automatically.

However it seems to be a proprietary standard with no public documentation. :( at least i was unable to find anything that didnt cost money.

These look like regular EIA-608 packets so raspi-teletext should already support it. You just need to give it the appropriate bits and it will draw them. raspi-teletext doesn't contain any encoding capability. That is a job for a separate tool like vbit2. I don't know what people are using to generate the US data formats and I have no way to even test it.
