Problems solved by technology

However, many users do not know which CC format is in the current signal, so they do not know which CC format to choose, and the format of the CC signal transmitted by the signal will change due to different programs or viewing time periods. It is necessary to switch the CC format of the decoding module in the TV according to the current CC signal, which brings a lot of inconvenience and trouble to the user watching TV programs with CC signals

Embodiment Construction

[0044] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0045] Such as figure 1 as shown, figure 1 It is a flow chart of a method for automatically displaying multi-format closed captions by a television set in an embodiment of the present invention. The method for automatically displaying multi-format closed captions by a television set mentioned in this embodiment includes:

[0046] Step S10, the TV receives the closed caption CC signal, and decodes the CC signal according to the CC encoding format in the decoding module;

[0047] In this embodiment, when setting the CC encoding format of the decoding module, the main parameters corresponding to the CC encoding format are also set, including the color table, character string table, decoding method, etc. of CC subtitles.

[0048] Step S20, judging whether the decoded CC subtitle is correct; if yes, then execute step S30...

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.

Description

technical field [0001] The invention relates to the technical field of televisions, in particular to a method and system for automatically displaying multi-format closed captions on televisions. Background technique [0002] With the end of the financial crisis and the continuous improvement of global living standards, high-quality TVs have huge sales potential in the international market. [0003] In some countries and regions, TV signals often carry Closed Caption (CC) information during transmission. CC subtitles are text versions of TV, movie and computer image explanations. In addition to dialogue, there are also current scenes. Information such as sound and soundtrack.
