The application discloses a digital TV playback method based on the value of the focus degree, which receives a digital signal, converts it into original video and original audio, plays the original video, and plays the original audio; builds a Bluetooth channel to obtain the first head image; converts the first head Input the internal image into the orientation classification model to obtain the first face orientation; if the first face orientation points to the digital TV display, the environmental sound data is obtained through the sound collector and compared with the original audio; if there is an abnormal sound, the first face orientation is used The second camera captures the eye image; input it into the focus degree prediction model to obtain the focus degree value; if the focus degree value is less than the focus degree threshold value, then generate the first supplementary video clip and the first supplementary audio clip, and pass the first supplementary audio clip through the Bluetooth channel The video segment and the first supplementary audio segment are sent to the mobile terminal, which improves the effective playback rate of digital TV playback, and saves the overall time without dragging back the progress bar.
Description
technical field [0001] The present application relates to the field of digital television, in particular to a method and device for playing digital television based on the value of the focus degree. Background technique [0002] When traditional digital TV transmits digital signals and plays audio and video, it will only play according to predetermined parameters (such as predetermined playback speed), without considering the actual situation of the viewer. However, when the viewer is watching a digital TV program, there is a situation of being distracted. Although the viewer is still in front of the digital TV display, he actually fails to hear or see the audio and video of this part (or, the viewer's Although the visual organs and auditory organs have obtained visual information and auditory information, when a natural person is in a state of distraction, they will instinctively ignore this part of the information, so it is also regarded as failing to hear or see this part...
