Abstract

The invention discloses a method and a system for automatically displaying multi-format hidden captions of a television set. The method comprises the following steps of: receiving a hidden caption communication center (CC) signal through the television set, and decoding the CC signal according to a CC encoding format in a decoding module; and judging whether a decoded CC caption is correct or not, if so, displaying the decoded CC caption, otherwise, automatically switching the CC encoding format in the decoding module, and decoding the CC signal according to the newly switched CC encoding format. Correct decoding is finished by automatically switching the CC encoding format in the decoding module, so that the trouble caused by manual switching by a user can be avoided. The encoding format switching operation is realized on a background of the television set, so that the smoothness of watching television programs in the television set for the user is not affected, and the user experience is effectively improved.
