Closed captioning management system
View Patent ↗Media content typically includes closed captioning information such as subtitles 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.
1. A method, comprising:
receiving a request from a viewer to play media content at a device;
monitoring environmental noise using a sensor associated with the device;
generating a sound profile for the media;
generating an environmental noise profile based on the environmental noise;
determining that environmental noise would adversely impact a viewing experience of the media stream, wherein determining that environmental noise would adversely impact a viewing experience of the media stream includes comparing spectral components of the environmental noise profile and temporal characteristics of the environmental noise profile to the sound profile of the media to determine whether the noise would interfere with program viewing;
automatically displaying an option to turn on closed captioning for a video program in the media stream upon determining that the environmental noise would adversely impact a viewing experience; and
replacing video advertisements with text or image advertisements when a noise profile is determined to be undesirable.
2. The method of claim 1 , wherein the sensor is a microphone.
3. The method of claim 1 , wherein monitoring environmental noise comprises monitoring environmental noise volume.
4. The method of claim 1 , wherein monitoring environmental noise comprises analyzing spectral components of environmental noise.
