7.1.1 Captioning playback
Where ICT displays video with synchronized audio, it shall have a mode of operation to display the available captions. Where closed captions are provided as part of the content, the ICT shall allow the user to choose to display the captions.
NOTE 1: Captions may contain information about timing, colour and positioning. This caption data is necessary for caption users. Timing is used for caption synchronization. Colour can be used for speaker identification. Position can be used to avoid obscuring important information.
DE Comment: These are standard functions of TVs.
NOTE 2: If a Braille device is connected, the ICT should provide an option to display captions on the Braille device.
DE Comment on Note 2: I don't know how widely this is supported - a standard for USB Braille displays does exist. However, only a "should".
NOTE 3: Clause 7.1.1 refers to the ability of the player to display captions. Clauses 9.1.2.2, 10.1.2.2 and 11.1.2.2 refer to the provision of captions for the content (the video).
DE Comment on Note 3: N/A. Note: This is a core function of the TV.
