The frame rate, that is, the playback module (2) ignores the time stamp of each screen information, and outputs the screen information stored in the buffer 123 at a faster playback speed. Alternatively, the play module 125 may directly discard the screen information temporarily stored in the buffer (2) during the video mode. In this way, the screen information received after receiving the I2 is the user's screen during the operation, because the time delay is short, the system can not even detect it, so the user can have a sense of time control. . 1 丨 25 ^ device 12 switches from the operating mode to the video mode, the playback module ^ temporarily t (four) stored in the slow touch 123 information, or reduce the output temporarily: over -123 towel screen information The speed, for example, reduces the frame rate of the output video 'to enable the buffer (2) to temporarily store more screen information. After accumulating the screen information of the set length, the play touch 125 can output the screen at the original playback speed according to the time stamp of the information in each camp. In an embodiment, the receiving device 12 can be built into the display device 2, and the device 12 can include a --connection interface 126, which is coupled to the second processing unit. The display device 20 can be electrically connected to the receiving device i2 via the first connection interface 126. The first connection interface 124 can be a video connection port; the display device 2 can be displayed for a television, a display or a projector. Electronic device inside. The receiving device 12 can include a second connection interface 127 that is warfarely connected to the jth factory. The user interface device Deng can be connected via a second connection (4). The user can use the user connected to the receiving device 12 to operate the remote host. And 7 can be - USR into: For example, the second connection interface 127 is Satoshi, 丨面. According to the above architecture, the display device 2 that lacks the wheel device, such as the 201223275 projector, can be controlled by the user to connect to the receiving device 12 including the user interface device, for example, to select a video to be played. . It should be noted that the transmission device 11 can also include a first detection module 115 electrically connected to the first processing unit 113. The first detecting module 115 is also configured to detect the operation of the user, and output a corresponding mode switching signal to the receiving device 12, and the receiving device 12 switches to the reduced shape according to the mode of the transmission device 11 Broadcasting. For example, the alpha user, .5_ is operated by the user interface device connected to the receiving device n to operate the remote power circuit 61, and the wireless device or the wireless mouse operates, and the receiving device 12 can still transmit
