It seems as if does not really fully know this format... The video is generated by video recording program that records a broadcast. I tried TVTest (https://github.com/tsukumijima/TVTest) for Windows and also tried recpt1 (https://github.com/stz2012/recpt1.git) and both of them produce the same output. Are those trying to read and understand the file? (That isn't clear.) What was used to record this?
