Subtitle (Closed Caption)
The document describes how to implement closed captions regarding the Federal Communication Commission regulations
** This class will not be supported in 2015.
All functionalities of AppsFramework are more improved, integrating with CAPH. Therefore Appsframework is not supported since 2015 Smart TV.
To comply with the Federal Communications Commission’s (FCC) closed caption rule, Content Providers (CPs) must support closed captions for video. In particular, applications bundled with a device are considered to be part of the device, and are covered by more stringent rules pertaining to devices (Section 203 of the CVAA). For these bundled applications, CP must use either their own solution or manufacturer’s solution for captioning. This solution must handle complicated closed caption user attributes as listed in the FCC rules. The definition of these attributes draws from the CEA 708 standard.
If you want to use Samsung’s solution, we support CEA-708, SMPTE-TT and SAMI formats.
If you want to use your own solution
- Case 3: own solution - see Using own Closed Captions Solution.
If content contains CEA-708 captions, nothing has to be modified. The Samsung platform will parse CEA-708 data and render it based on the user’s closed caption attributes settings. The Samsung native UI supports user’s closed caption attributes settings.
Samsung supports CEA-708 with the following codecs:
- MPEG-2 Video: ATSC A/53, user data
- H.264/AVC: ATSC A/72, ATSC_user_data() Syntax using the H.264 SEI Syntax
