Abstract

The invention discloses a display device and a key transmission fault tolerance method, and is particularly suitable for a social television. The display device includes a display configured to display image content; a first controller configured to receive the key event and transmit the key event; a second controller configured to receive the key event transmitted by the first controller and detect whether a lifting event corresponding to a pressing event in the received key event is received within preset time or not, wherein if so, the corresponding pressing event and lifting event are normally processed, and a lifting event corresponding to the pressing event is simulated if not. When the key transmitted to the second controller by the first controller is lost, namely the second controller does not receive the corresponding pressing and lifting event, one lifting event is simulated, so that the effectiveness of the key on the second controller is ensured, the problem of key disorder caused by key loss of dual systems is prevented, and the use experience of a user is greatly improved.

Description

[0001] This application claims the priority of the Chinese patent application submitted to the China Patent Office on June 10, 2019, with application number 201910497424.6, and the title of the invention is "Fault-tolerant method, system and display device for key transmission between dual systems", the entire content of which is approved by the application incorporated in this application. technical field [0002] The present application relates to the technical field of smart TVs, and in particular to a display device and a fault-tolerant method for button transmission. Background technique [0003] The current TV is equipped with a remote control, and the user can operate the TV through the remote control, such as adjusting the volume, adjusting the channel, etc. In some scenarios, the user may continue to press a button on the remote control for a long time, such as , some users keep pressing the volume keys while adjusting the volume, in which case the remote keeps send...
