Aligning a closed caption track to a media content includes calculating the offset and the drift between the closed caption track and the media content item. The closed caption track is aligned to the media content item as a function of the calculated offset and drift.

The present invention relates to a device and a method for transmitting and receiving a broadcast signal comprising a subtitling service. Provided in one embodiment of the present invention is a method for transmitting a broadcast signal, the method comprising the steps of: generating a broadcast signal comprising video data and subtitle data; and transmitting the generated broadcast signal. According to the embodiment of the present invention, a transport stream providing a digital broadcast subtitling service using an XML subtitle may be transmitted.

A broadcast service receiving method of a broadcast receiving device is provided. The method includes: receiving a trigger; receiving a triggered object; when a target of the received trigger is the triggered object, performing a trigger action on the triggered object at a trigger time; receiving real-time data available for the triggered object by an operation of the triggered object according to the performing of the triggered action; and providing a service by using the real-time data.

The present disclosure relates to a method and a device for playing multimedia. The method may comprise: obtaining at least one of audio data and subtitle data of a first preset time length before a pause position of a multimedia; determining a starting position of a complete semantic statement according to at least one of the audio data and the subtitle data; and continuing to play the multimedia according to the starting position when an instruction of continuing to play the multimedia is detected or a condition of continuing to play the multimedia is met.

A method for preparing supplementary media content for coordinated transmission with multimedia content includes accepting the multimedia content including an audio portion, accepting the supplementary media content associated with the multimedia content, and validating the supplementary media content according to the audio portion of the multimedia content.

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.

The present disclosure relates to a method and a device for playing multimedia. The method may comprise: obtaining at least one of audio data and subtitle data of a first preset time length before a pause position of a multimedia; determining a starting position of a complete semantic statement according to at least one of the audio data and the subtitle data; and continuing to play the multimedia according to the starting position when an instruction of continuing to play the multimedia is detected or a condition of continuing to play the multimedia is met.

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.

Disclosed is a network-on-chip including a first data converter that receives first image data and second image data from at least one image sensor and encodes one image data among the first image data and the second image data, into first data, based on whether the first image data is identical to the second image data and a second data converter that receives non-image data from at least one non-image sensor and encodes the received non-image data into second data. The network-on-chip outputs the first data and the second data to transmit the first data and the second data to an external server at a burst length.

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.
