The invention discloses a digital television playing method based on a focusing degree numerical value. The digital television playing method comprises the steps of receiving a digital signal, converting the digital signal into an original video and an original audio, playing the original video and playing the original audio; constructing a Bluetooth channel to obtain a first head image; inputting the first head image into an orientation classification model to obtain a first face orientation; if the first face orientation points to the digital television display, obtaining environment sound data through a sound collector, and comparing the environment sound data with the original audio; if the abnormal sound exists, acquiring an eye image by adopting a second camera; inputting into a focusing degree prediction model to obtain a focusing degree value; and if the focusing degree numerical value is smaller than the focusing degree threshold value, generating a first supplementary video clip and a first supplementary audio clip, and sending the first supplementary video clip and the first supplementary audio clip to the mobile terminal through the Bluetooth channel, so that the effective playing rate of digital television playing is improved, a progress bar does not need to be dragged back, and the overall time is saved.
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...
