This application discloses a method for using closed captions to initiate display of related content. A computer system identifies a set of first information in closed captions of a video stream, and searches an identity database using the set of first information as queries. The identity database stores a plurality of identities, and each identity is associated with a name and an importance metric. The computer system identifies one or more identities in the identity database based on the respective importance metrics of the one or more identities, and obtains second information of one or more content files related to the identities identified in the identity database. Upon obtaining the second information, the computer system generates instructions to invoke an application for presenting the second information of the one or more content files to the user of the computing device.

The various implementations described herein describe using an audio stream to identify metadata associated with a currently playing television program. In one aspect, a method is performed at a computing device having processors and memory storing programs to be executed by the processors. The computing device obtains audio description data of a video stream for a media program. The audio description data comprises a synchronized audio narrative describing what is happening visually in the media program. The computing device identifies a set of information items including one or more words in the audio description data. The computing device transmits the words to a server. After the transmitting, the computing device obtains from the server information of content files related to the words. In response to obtaining the information, the computing device causes the information to be displayed on an electronic device that is distinct from the computing device.

System and methods for finding and analyzing targeted content from audio and video content sources, including means and methods for extracting captions from audio and video content sources; searching the captions for a mention of at least one target; extracting audio and video segments relating to the at least one target; delivering extracted audio and video segments to a user device; harvesting social media data relevant to the at least one target; analyzing the search results in correlation with the social media data for target content.

Management of graphical overlays for use in stereoscopic video where the graphical overlay is positioned relative to depths associated with objects showing in the video. A disparity offset processor may be configured to facilitate generating overlay mapping information as a function of object depth maps in order to facilitate positioning one or move graphical overlays relative to corresponding objects.

Methods, apparatuses, and non-transitory computer-readable storage mediums for providing and/or processing non-closed caption data. The reception apparatus includes a receiver, a parser, and a processor. The receiver receives closed caption service data. The closed caption service data includes closed caption data within a first service block having a service number in the range of 1-6, and non-closed caption data within a second service block having a different service number in the range of 1-6. The closed caption data includes closed caption text. The parser parses the non-closed caption data within the second service block having the different service number in the range of 1-6. The processor performs a function based on the parsed non-closed caption data.

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.

An encoder and a re-packager circuit. The encoder may be configured to generate one or more bitstreams each having (i) a video portion, (ii) a subtitle placeholder channel, and (iii) a plurality of caption channels. The re-packager circuit may be configured to generate one or more re-packaged bitstreams in response to (i) one of the bitstreams and (ii) a selected one of the plurality of caption channels. The re-packaged bitstream moves the selected caption channel into the subtitle placeholder channel.
