A calibration system for media content, the calibration system comprising: a memory configured to store a media item and expected-emotions-tagging metadata for the media item, wherein the expected-emotions-tagging metadata indicates an associative relationship between a set of time slots and a set of specified emotional states that are expected from an audience at the set of time slots at playback of the media item; a media device configured to execute the playback of the media item to the audience; a plurality of different types of sensors configured to capture emotional response data from the audience at the playback of the media item; and control circuitry configured to: embed a marker in the media item played by the media device based on the expected-emotions-tagging metadata; compute a reaction delay for the duration of an emotional response of the audience captured by the plurality of different types of sensors for a scene of the media item with respect to the expected duration of the marker that spans a first time slot that corresponds to the scene in the media item; compute a transmission delay for the emotional response of the audience captured by the plurality of sensors for a scene of the media item with respect to the duration of the first marker, the transmission delay being the delay between the emotional response being produced by the audience and the plurality of sensors capturing and transmitting the emotional response; and calibrate the position of the marker in the media item to associate a first set of frames of the scene with the emotional response, by delaying the position by an amount equal to the sum of the computed reaction delay and the computed transmission delay. a memory configured to store a media item and expected-emotions-tagging metadata for the media item, wherein the expected-emotions-tagging metadata indicates an associative relationship between a set of time slots and a set of specified emotional states that are expected from an audience at the set of time slots at playback of the media item; a media device configured to execute the playback of the media item to the audience; a plurality of different types of sensors configured to capture emotional response data from the audience at the playback of the media item; and control circuitry configured to: embed a marker in the media item played by the media device based on the expected-emotions-tagging metadata; compute a reaction delay for the duration of an emotional response of the audience captured by the plurality of different types of sensors for a scene of the media item with respect to the expected duration of the marker that spans a first time slot that corresponds to the scene in the media item; compute a transmission delay for the emotional response of the audience captured by the plurality of sensors for a scene of the media item with respect to the duration of the first marker, the transmission delay being the delay between the emotional response being produced by the audience and the plurality of sensors capturing and transmitting the emotional response; and calibrate the position of the marker in the media item to associate a first set of frames of the scene with the emotional response, by delaying the position by an amount equal to the sum of the computed reaction delay and the computed transmission delay. embed a marker in the media item played by the media device based on the expected-emotions-tagging metadata; compute a reaction delay for the duration of an emotional response of the audience captured by the plurality of different types of sensors for a scene of the media item with respect to the expected duration of the marker that spans a first time slot that corresponds to the scene in the media item; compute a transmission delay for the emotional response of the audience captured by the plurality of sensors for a scene of the media item with respect to the duration of the first marker, the transmission delay being the delay between the emotional response being produced by the audience and the plurality of sensors capturing and transmitting the emotional response; and calibrate the position of the marker in the media item to associate a first set of frames of the scene with the emotional response, by delaying the position by an amount equal to the sum of the computed reaction delay and the computed transmission delay.
