This media format provides time-lined decorated text, usable for subtitling
and karaoke. The payload format enables the usage in streaming and
multicast delivery. The payload format is designed using proved concepts
and keeps things simple while still robust. Suitable mechanism are
specified for improving robustness of this low bit-rate media.

Working Group Summary:
