Media content typically includes closed captioning information such as subtitled in domestic and foreign languages. Techniques and mechanisms provide that closed captioning information may be toggled on/off using menu options and preferences as well as automatically managed by intelligently monitoring the environment surrounding a device. Device sensors such as microphones and vibration monitors determine the noise level of an environment as well as the spectral characteristics of the noise to determine whether the noise profile would interfere with the video playback experience. A particular environmental noise profile could automatically trigger the display of closed captioning information or present an easy access, otherwise unavailable toggle to display closed captioning information associated with a video stream.

A method and an apparatus for processing a high dynamic range (HDR) video including a subtitle, where the method includes: encapsulating HDR video data into a video data frame that matches a transmission interface; encapsulating subtitle information into a subtitle information frame that matches the transmission interface; and separately transmitting the video data frame and the subtitle information frame to a display device through the transmission interface, where the video data frame and the subtitle information frame are packets in two types of formats. According to the method provided in this application, content and subtitle information of a dynamic metadata HDR video are separately transmitted to the display device. In this way, the display device can obtain the separated video content and subtitle information, and then separately perform corresponding processing on the HDR video and a subtitle.

A transmitting apparatus including circuitry configured to generate caption data corresponding to content data and having elements defined in Extensible Markup Language (XML), and output the content data and the generated caption data to a reproducing device.

A reception apparatus is provided that includes circuitry configured to receive a digital data stream. The circuitry is configured to acquire closed caption information included in the digital data stream. The circuitry is configured to acquire control information including selection information indicating a selection of a specific mode from a plurality of modes for specifying when closed caption text is to be displayed. The circuitry is further configured to output the closed caption text included in the closed caption information for display to a user, at a display time according to the specific mode, based on the selection information included in the control information.

Systems, devices and methods are described to process timed text that is associated with media or other video programming. Pre-set data that describes the particular format of the timed text that is associated with a program is initially received and stored at the media receiver prior to receiving the program with encoded timed text. The timed text that is associated with the received program is interpreted according to the pre-set data previously stored at the media receiver, and the program with the interpreted timed text is output to a display for presentation to the viewer.
