Comment (by pbk):

 Hi,
 I think you are missing following line in the Table 26: 8-bits per pixel
 code string:
  8-bit_zero 8 bslbf

 So, the total zero bits are 16 (8 + 1 + 7).

 When I was developing my own ffmpeg TS muxer with ability to convert
 ttml/sgml/vwtt to DVB, I couldn't figure out what the hell is wrong.
 Subtitle rendering in both VLC anf MPC-HC was completely messed.
 After adding the missing zero byte to the end of the string, both players
 started to render the subtitles perfectly.
