1 year ago I haven't looked at writing any tests, but can work on that.
Yet to be decided is if and how to display the information in ld-analyse:
aspect ratio
- 4:3
- 16:9
- Letterbox
CGMS-A
- Copying is permitted without restriction
- Condition not to be used
- One generation of copies may be made
- No copying is permitted
APS trigger bits
- PSP off
- PSP on, split burst off
- PSP on, 2-line split burst on
- PSP on, 4-line split burst on
Of the 14-bit payload, only 6 bits are defined in IEC 61880. It's possible that other data could be inserted as well?
Lines 20 and 283 can contain information about aspect ratio, CGMS-A, and APS. Store these 14-bits in the JSON.
NTSC only. PAL uses WSS to provide similar functionality.
