In practice, the setting signal 101 itself may include the data of the identification code of the organic upper box 60. When the signal receiving device 20 receives the setting signal 101, the processing device 40 may select a plurality of preset identification codes according to the identification code of the set-top box 60. In 301, the preset identification code 301 identical to the identification code of the set-top box 60 is automatically found to complete the setting. The setting signal 101 can be derived from the two-dimensional bar code of the set-top box 60, the QR Code or the signal sent by the set-top box 60, and the setting signal 101 can be read by the signal receiving device 20 to complete the setting.

Please refer to FIG. 3, FIG. 4 and FIG. 5 at the same time, which is a schematic diagram of the setting of the video and audio playback system of the present invention, a schematic diagram of the channel selection, and a flow chart of the steps of the channel selection control method of the present invention. The video and audio playback system of the present invention is required to communicate with the set-top box 60 through the television 200 before the channel selection operation is performed. The television 200 can include the signal receiving device 20 and the data storage device 30. The processing device 40 and the display device 90 have an identification code corresponding to the channel selection control mode, and the set-top box 60 can be electrically connected to the television 200.

In step S11, a plurality of preset identification codes 301 are stored in the data storage device 30.

In step S12, the signal receiving device 20 can receive the setting signal 101 and transmit it to the processing device 40 to cause the processing device 40 to enter the first mode 401. The source of the setting signal 101 can be the signal sent by the remote control device 10, or The signal receiving device 20 reads the two-dimensional bar code on the set-top box 60, the QR Code, or the signal transmitted from the set-top box 60.

In step S13, the processing device 40 determines whether the setting signal 101 includes the identification code of the set-top box 60, where the identification code can be the model of the set-top box 60, the cable television provider, the wireless television supplier, and the network television supply. The name of the quotient, the two-dimensional barcode or the QR Code, if the determination is YES, the process proceeds to step S14, and if the determination is otherwise, the process proceeds to step S15.

In step S14, the processing device 40 automatically searches for the corresponding preset identification code 310 identical to the identification code from the plurality of preset identification codes 301, and proceeds to step S16.

In step S15, after the processing device 40 receives the setting signal 101, it can be in multiple pre- In the identification code 301, the corresponding preset identification code 310 identical to the identification code is manually selected, and the process proceeds to step S16.

In step S16, the processing device 40 controls the data transmission on the set-top box 60 according to the corresponding preset identification code 310. This step is to enable the processing device 40 to communicate with the set-top box 60, so that the processing device 40 switches to the first Two mode 402.

In step S21, the signal selection device 20 can be received by the signal receiving device 20 and transmitted to the processing device 40.

In step S22, the processing signal 40 is processed by the processing device 40 to form a control signal 410. The control signal 410 here can be a channel selection control mode corresponding to the set-top box 60. In practice, it can be received according to the set-top box 60. The frequency and the code of the signal convert the channel selection signal 102 to form the control signal 410. The wireless receiving device of the set-top box 60 receives the control signal 410, and the control signal 410 generated by the processing device 40 can also be transmitted to the machine through an electrical connection. Upper box 60.

In step S23, the control device 40 transmits the control signal 410 to the set-top box 60, so that the set-top box 60 selects the video source signal 701, and converts it into the video signal 702 for transmission to the display device 90.

In step S24, the video signal 702 can be displayed by the display device 90.

In practice, the plurality of preset identification codes 301 stored in the data storage device 30 may be updated by the transmission device 80 to correspond to the new control mode of the set-top box 60.

Please refer to FIG. 1 , FIG. 3 and FIG. 4 at the same time, which is a schematic diagram of the operation of the conventional method for selecting the station control, and a schematic diagram of the setting and channel selection of the video and audio playback system of the present invention. The conventional method of selecting a station requires at least two remote controllers. Since the signal transmission of the remote controller and its corresponding receiving device produced by different suppliers does not have a certain standard, it is also necessary to consider the receiving devices of various other appliances. When the signal of the TV remote controller is received, the development of the remote controller and its corresponding receiving device is increasingly complicated and difficult to integrate.

Taking TV programs as an example, if you need to remotely control different devices, such as watching TV and using TV 300 and set-top box 60 at the same time, you need to use TV remote control 11 to input TV remote control signal 111, which is used to turn on TV 300 switch or The volume control and the use of the set-top box remote control 12 to input the set-top box remote control signal 121 perform the channel selection operation.

The video playback system for providing the channel selection function of the present invention is a method for controlling the channel selection of the set-top box 60, integrated into the data storage device 30, and converted by using the preset identification code 301 in the data storage device 30. After the processing program reads the setting via the processing device 40, it can assist the signal selection device 102 of the remote control device 10 (ie, the remote controller) received by the signal receiving device 20 to be converted into the control channel selection of the corresponding set-top box 60. The input command is such that the channel selection function of the set-top box 60 can be controlled using a remote control device 10.

The embodiments described above are merely illustrative of the technical spirit and the features of the present invention, and the objects of the present invention can be understood by those skilled in the art, and the scope of the present invention cannot be limited thereto. That is, the equivalent variations or modifications made by the spirit of the present invention should still be included in the scope of the present invention.
