Specifically, if Djl is less than or equal to the preset maximum error value, it indicates that the repair is successful, and the post-repair processed data is sent to the display device as the playing data, and S240 is executed.
If Djl is greater than the preset maximum error value, it indicates that the repair is failed, and the lost frame is repaired again.
Specifically, the repair unit directly marks the conversion data as the non-damaged data to be processed as the play data, sends the play data to the display device, and executes S240.
S240: and playing the playing data.
Specifically, the display device plays the play data after receiving the play data.
The method and the device have the technical effects of simplifying the operation process of the display terminal, improving the data viewing effect of the operation terminal and avoiding the data language not meeting the user requirements.
