Problems solved by technology

However, the digital TV terminal has its own characteristics, that is, the viewer of the digital TV terminal usually sits or lies on the sofa to watch the program. At this time, the posture of the viewer is not suitable for inputting control signals, especially complex control signals. However, neither the traditional remote control scheme nor the voice recognition control scheme can effectively solve the human-computer interaction problem of digital TV terminals.
Therefore, the human-computer interaction scheme involving digital TV terminals needs to be improved

Embodiment Construction

[0047] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0048] refer to figure 1 , the embodiment of the present application provides a passive digital TV terminal human-computer interaction method, including the following steps:

[0049] S1. Before playing the video, the digital TV terminal obtains the first playback parameter, and plays the specified video based on the first playback parameter; and then uses the preset two-way communication network to determine whether the content played by the terminal is the specified video or not. Select a standard to obtain m mobile terminals; wherein, the m mobile terminals are playing ...

Abstract

This application discloses a human-computer interaction method for a passive digital TV terminal, which includes acquiring the first playback parameter and playing a specified video; acquiring m mobile terminals; acquiring m playback parameter sequences, obtaining m screened parameter sequences, and generating m A sequence of time points; generate a set of time points, and perform clustering processing to obtain n first cluster centers; call playback parameters, and set up n playback parameter sets; obtain n offset values ​​correspondingly; Parameters are correspondingly superimposed on the n offset values ​​to obtain the second playback parameter, the third playback parameter, ..., the n+1th playback parameter; the corresponding modification of the playback parameters of the digital TV terminal; obtain the first facial image; Obtain the first prediction result output by the negative information prediction model; if the first prediction result is not negative, it will generate and continue to play the specified video, realizing the human-computer interaction including the adjustment of playback parameters without complicated control by the viewer Purpose.

Description

technical field [0001] This application relates to the field of digital television, in particular to a passive digital television terminal human-computer interaction method and device. Background technique [0002] Human-computer interaction involving digital TV generally refers to the signal interaction between a natural person and a digital TV terminal. The traditional human-computer interaction solution of the digital TV terminal realizes the input of the control signal through the remote control or further voice recognition technology. However, the digital TV terminal has its own characteristics, that is, the viewer of the digital TV terminal usually sits or lies on the sofa to watch the program. At this time, the posture of the viewer is not suitable for inputting control signals, especially complex control signals. However, neither the traditional remote controller control scheme nor the voice recognition control scheme can effectively solve the human-computer interac...
