Embodiment 1

[0025] figure 1 It shows a flow chart of a communication method for a modular TV provided by the first embodiment of the present invention, which is described in detail as follows:

[0026] Step S11, after the screen end powers on the card end, the card end loads the serial port driver and the high-definition multimedia interface HDMI driver.

[0027] Before the screen end powers on the card end, the screen end performs hardware initialization actions, such as the action of initializing the display device. After completing the hardware initialization action, the screen side powers up the card side through the general purpose input / output (General Purpose Input Output, GPIO) port, so that the card side performs the Boot startup action, loads the serial port driver, and loads the high-definition multimedia interface. (High Definition Multimedia Interface, HDMI) driver and other actions.

[0028] Preferably, when the serial port driver and the high-definition multimedia interfa...

Embodiment 2

[0047] figure 2 It shows the flow chart of the interaction between the screen terminal and the card terminal provided by the second embodiment of the present invention. In this embodiment, before powering on the card terminal, an external device is inserted. Insert, not limited here.

[0048] Step 1. After the user powers on and inserts the external device equipped with the system to be upgraded on the card end, the screen end starts to complete part of the hardware initialization work.

[0049] Step 2. The screen end powers up the card end by pulling up the GPIO port pin to start the card end.

[0050] Step 3. The screen continues to complete the image device initialization work, turn on the backlight, and output the boot logo.

[0051] Step 4. The screen detects whether the user presses the power button of the display for a long time. Because the display button is on the screen, the detection process is on the screen. This detection is mainly for the forced upgrade of the...

Embodiment 3

[0061] image 3 A structural diagram of a communication device for a modular television provided by the third embodiment of the present invention is shown. For convenience of description, only parts related to the embodiment of the present invention are shown.

[0062] The communication device of the modular TV includes a screen terminal 31 and a card terminal 32 . in:

[0063] The screen terminal 31 includes a signal switching unit 311 and a key event detecting unit 312 .

[0064] The card end 32 includes a driver loading unit 321 and a key event executing unit 322 .

[0065] The driver loading unit 321 is configured to load the serial port driver and the high-definition multimedia interface HDMI driver after the screen end powers on the card end.

[0066] Further, after the HDMI driver is loaded, the screen terminal needs to verify the legality of the card terminal. At this time, the communication device of the modular TV further includes: an authentication request sendin...

Abstract

The invention is applicable to the field of module televisions and provides a communication method and device for the module televisions. The method comprises the steps that after a screen end powers on a card end, the card end loads a serial driver and an HDMI driver; the screen end switches an input signal to an HDMI information source so as to obtain a processed HDMI information source from an HDMI; the screen end detects whether a key pressing event is received, and forwards the received key pressing event to the card end after receiving the key pressing event; the card end executes a corresponding action according to the received key pressing event. By means of the communication method and device, the turn-on time of the module televisions can be shortened.

Description

technical field [0001] The invention belongs to the field of modular televisions, in particular to a communication method and device for modular televisions. Background technique [0002] Modular TV refers to a customizable and upgradeable smart TV. Users can customize differentiated product function modules according to their own needs. In a modular TV, there are two boards. In order to distinguish these two boards, the board that is closely related to the display screen and will not be replaced is called the screen end, and the other board that can be plugged and replaced is called the card end. . [0003] The existing communication method of the modular TV mainly processes video information through the screen terminal, and plays the processed video information. Since the configuration of the screen end is generally low, the use of the existing modular television communication method will easily lead to slow processing of video information and poor playback effect. Con...
