What are forced subtitles on Blu-ray disc
What is Forced Subtitle
Forced subtitles are common on movies and only provide subtitles when the characters speak a foreign or alien language, or a sign, flag, or other text in a scene is not translated in the localization and dubbing process. In some cases, foreign dialogue may be left untranslated if the movie is meant to be seen from the point of view of a particular character who does not speak the language in question.
Forced Subtitles on Blu-ray Disc
Usually, you may find forced subtitles easily with your Blu-ray disc and DVD disc. While, unlike DVD, on Blu-ray, each subtitle item has an attribute that specified whether particular subtitle appearance should be forced. Forced subtitles are shown regardless of current player setting, typically when movie contains a foreign language scene. The "forced" attribute is assigned per individual subtitle image, so entire subtitle track must be scanned to determine if forced subtitles are present.
