As per the CEA-708-B specification, section 8.10.4, cues don't necessarily need either an ETX command or any of the C1 commands before being updated with the latest buffered content. While those commands do indicate that the cues should be updated immediately, the cues can also be updated after a service block has been processed if it appended text to the buffer. ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=149673162
