Problems solved by technology

[0004] In the process of carrying out the research of the present invention, the inventor found that: with the improvement of living standards, the number of TVs owned by families is increasing, and each room may be equipped with a TV; but each TV is independently executed. Display operation, and the need to obtain signal sources separately, which leads to an increase in the number of signal sources required in the home, making it difficult to achieve complex control of the TV

Embodiment 1

[0045] figure 1 It is a schematic structural diagram of the main control device of the smart TV system provided in Embodiment 1 of the present invention, the main control device includes: at least one signal source input port 110, at least one main control output port 130, a central control board 120, at least one main control module 140 and at least one display driver board 125 .

[0046] Specifically, the signal source input port 110 is used to obtain the signal stream from the signal source; the main control output port 130 is used to connect with the display device, and output the signal stream to the display device for playback; the central control board 120 is connected to the signal source input port 110 Between the main control output port 130, it is used to establish a transmission path for signal flow between the signal source input port 110 and the main control output port 130; the main control module 140 is connected to the central control board 120 respectively, a...

Embodiment 2

[0088] figure 2 It is a schematic structural diagram of the main control device of the smart TV system provided by Embodiment 2 of the present invention. In this embodiment, on the basis of the foregoing embodiments, a control terminal transcoding module is added.

[0089] like figure 2 As shown, the control terminal transcoding module 115 is connected to the central control board 120, and is used for transcoding the signal stream transmitted from the central control board 120 to the main control output port 130 according to the format requirements of the output display device.

[0090] In the actual video viewing process, due to differences in signal sources, the format of the signal stream is different, and the common signal streams are V-BY-ONE and HDMI formats. Display driver boards in display devices also have different processing capabilities for the format of the signal stream. The signal flow that can be directly processed by the display driver board can be direct...

Embodiment 3

[0094] image 3 Embodiment 3 of the present invention provides a schematic structural diagram of a master control device of a smart TV system. This embodiment further provides a solution for receiving user instructions on the basis of the above embodiments.

[0095] Specifically, the master control device further includes an instruction receiving unit 150 . The instruction receiving unit 150 is connected with the central control board 120 and / or the main control module 140, and is used for receiving user instructions input by the user through key operation or remote control. The instruction receiving unit 150 can be a Bluetooth receiving device, an infrared receiving device or a 2.4GHz wireless receiving device, etc., and can directly receive and recognize the remote control instruction sent by the user. Key operations include hardware keys on the main control device or display device, or touch screen keys.

[0096] The main control device may also include a main control inp...

Abstract

An embodiment of the invention discloses a main control device and display device of a smart TV system and method and system thereof and belongs to the field of electrical control technology. The maincontrol device includes at least one signal source input port, at least one main control output port, a central control board, at least one main control module and at least one display screen drive board, wherein the at least one display screen drive board is connected with the main control output port separately and is used for forming to-be-output signal streams into display screen drive signals and providing the display screen drive signals to the main control output port. According to the technical scheme provided by the embodiment, through arranging the main control device and the display device separately, the main control device can perform centralized control over multiple display devices. Therefore, coordinative control for distribution of signal streams generated by the signal source to the multiple display devices is realized. Also, the structure of the display device can be simplified, the cost of the display device can be reduced and the size of the display device can bereduced. Besides, by arranging the display screen drive board in the main control device, the structure of the display device is simplified further.

Description

technical field [0001] Embodiments of the present invention relate to smart electronic device control technologies, and in particular to a master control device and display device, method and system of a smart TV system. Background technique [0002] TV is a common electrical appliance in family life, and people watch TV programs through a TV connected to a set-top box. With the development of intelligent terminal technology, the operating system and client software can also be installed in the TV, and the video can be obtained from the background server through the network for viewing. [0003] The conventional structure of an existing TV generally includes: a display driver board (also called a TCON board), a display screen, a processing chip, a memory, a memory, a power supply, an input port, and a sound box. The working process of the existing TV is: through the input port, receive the original signal stream from the signal source such as the set-top box or network inte...
