Abstract
A video display method of a user terminal, includes determining whether ambient noise measured when a video is played is in an allowable range, and generating subtitles based on a voice signal included in the video in response to the ambient noise being determined to be out of the allowable range. The method further includes displaying the generated subtitles with the video.
Claims18
A video display method of a user terminal for displaying a voice signal of a video, the method comprising:
- determining, by a processor, whether earphones are connected to the user terminal;
- in response to the determining ascertaining that the earphones are connected to the user terminal, setting, automatically by the processor, a first allowable range of an amount of ambient noise;
- in response to the determining ascertaining that the earphones are not connected to the user terminal, setting, automatically by the processor, a second allowable range of an amount of ambient noise that is less than the first allowable range;
- receiving, through a microphone of the user terminal, an audio signal when the video is played;
- in response to the determining ascertaining that the earphones are connected to the user terminal, measuring, by the processor, the amount of ambient noise based on the received audio signal, and determining, by the processor, whether the measured amount of ambient noise is in the first allowable range;
- in response to the determining ascertaining that the earphones are not connected to the user terminal, measuring, by the processor, the amount of ambient noise based on an audio signal obtained by excluding an audio signal comprised in the video from the received audio signal, and determining, by the processor, whether the measured amount of ambient noise is in the second allowable range;
- generating, by the processor, subtitles based on a voice signal comprised in the video, in response to the ambient noise being determined to be out of the first allowable range or the second allowable range;
- and
- displaying, on a display of the user terminal, the generated subtitles with the video.

A user terminal for playing a video including a voice signal, comprising:
- a processor configured to:
- determine whether earphones are connected to the user terminal;
- in response to a determination ascertaining that the earphones are connected to the user terminal, set a first allowable range of ambient noise;
- in response to a determination ascertaining that the earphones are not connected to the user terminal, set a second allowable range of an amount of ambient noise that is less than the first allowable range;
- receiving, through a microphone of the user terminal, an audio signal when the video is played;
- in response to a determination ascertaining that the earphones are connected to the user terminal, measure the amount of ambient noise based on the received audio signal and determine whether the measured amount of ambient noise is in the first allowable range;
- in response to a determination ascertaining that the earphones are not connected to the user terminal, measure the amount of ambient noise based on an audio signal obtained by excluding an audio signal comprised in the video from the received audio signal and determine whether the measured amount of ambient noise is in the second allowable range;
- and
- generate subtitles based on the voice signal included in the video, in response to the ambient noise being determined to be out of the first allowable range or the second allowable range;
- and
- a display configured to display the generated subtitles with the video.

A user terminal for playing a video including an audio signal, comprising:
- a processor configured to:
- determine whether earphones are connected to the user terminal,
- set, based on user terminal volume control statistics, an allowable range of ambient noise,
- receive, through a microphone of the user terminal, an audio signal when the video is played, and
- determine whether an amount of ambient noise measured when the video is played is in the allowable range;
- and
- a display configured to display subtitles of the video with the video, in response to the ambient noise being determined to be out of the allowable range,
- wherein the user terminal volume control statistics are determined by statistically processing a plurality of past volume controls of the audio signal previously performed by a user and a plurality of amounts of ambient noise measured for each of the plurality of past volume controls,
- wherein the processor is configured to set the allowable range of ambient noise by recalling a previously measured amount of ambient noise from the plurality of amounts of ambient noise and its associated past volume control from the plurality of past volume controls, and
- wherein the processor is configured to measure the amount of ambient noise based on the received audio signal in response to a determination ascertaining that the earphones are connected to the user terminal, and measure the amount of ambient noise based on an audio signal obtained by excluding an audio signal comprised in the video from the received audio signal in response to a determination ascertaining that the earphones are not connected to the user terminal.
