There are many buttons 25 configured to be used for providing setting adjustments, besides the page up-down buttons 251 and the preview button 253, for adjusting the volume, brightness, for example.
In the illustrated embodiment, there are six display modules 209 according to the six displays 23. The processing module 205 includes a first processing block 2051 and a second processing block 2052. The signal emitting module 206 includes a first emitting block 2061 and a second emitting block 2062. The first processing block 2051 and the second processing block 2052 can be integrated together, and the first emitting block 2061 and the second emitting block 2062 can be integrated together.
The operating module 202 responds to the operation of pressing the buttons 25, and controls the processing module 205 to process the depressing operation to transmit corresponding remote control commands The operating module 202 includes a functional block 2021 and a control block 2023. The functional block 2021 responses to the operation of depressing the preview button 253, and then controls the second processing block 2052 to process the operation of depressing the preview button 253 to actuate or transmit a preview control command Thus, the television remote control device 20 starts the program preview function. Meanwhile, the second processing block 2052 transmits the preview control command to the second emitting block 2062, and controls the signal receiving module 207, the signal decompressing module 208, and the display modules 209 to start. The second emitting block 2062 emits the preview control command
The control block 2023 responds to the touching operation of the display 23, and then controls the first processing block 2051 to process the touching operation of the display 23 to a display control command The first processing block 2051 transmits the display control command to the first emitting block 2061, and the first emitting block 2061 emits the display control command to the command receiving unit 104 of the television 10.
