Fig. 1 is a schematic structural diagram of a video playing system in an embodiment. As shown in fig. 1, the video playback system includes a video playback device 10 and a display device 20 communicatively connected to the video playback device. The video playing device 10 includes a processor, and the control method of the video playing device provided in the present application may be applied to the processor shown in fig. 1, where the processor detects whether the display device 20 is in a shutdown mode, and if the display device 20 is in the shutdown mode, controls the video playing device 10 to enter a standby state; detecting whether the display device 20 is in a standby mode when the display device 20 is not in a shutdown mode, and controlling the video playing device 10 to enter a standby state if the display device 20 is in the standby mode; detecting whether the display device 20 is in the startup mode, and if the display device 20 is in the startup mode, controlling the video playing device 10 to enter the startup state.
Fig. 2 is a schematic diagram illustrating connection of a video playing system according to an embodiment. Wherein the video playback device 10 comprises: a video signal transmitting unit 110 for transmitting a video signal; a main power supply 120 for supplying power to the video signal transmitting unit; control means 130, configured to control a power supply state of the main power supply to control an operating state of the video playing device according to an operating mode of the display device; a switch unit 140, when the video playing device 10 is in a power-on state, the control means 130 controls the switch unit 140 to switch to a first state to conduct communication between the video signal transmitting unit 110 and the video signal receiving unit 210 of the display device 20; when the video playing device 10 is in the standby state, the control means controls the switch unit 140 to switch to the second state to detect whether the display device is in the on mode.
As shown in fig. 2, the video signal transmitting unit 110 transmits one tmds_data0/1/2 output to the display device 20, and the video signal transmitting unit 110 transmits the tmds_clk signal output to the video signal receiving unit 210 of the display device 20 after passing through the switching unit 140. The two inputs of the video signal receiving unit 210 are connected to a second power source, for example, 3.3V, through resistors R1 and R2, respectively. At the time of normal communication, the switching unit 140 is IN a first state, i.e., the terminal IN1 and the terminal OUT1 are turned on, and the tmds_clk signal is changed between 2.8-3.3V.
If the switching unit 140 is switched to the terminal IN2 and the terminal OUT1 to be turned on, the second power supply is connected through the resistors R1 and R2 at this time, and the control means detects that the tmds_clk signal is about 3.3V. When the display device enters the standby mode, the second power supply is turned off, and the control device detects that the TMDS_CLK signal is about 0V.
The first power supply of the display device 20 is connected to the HPD signal input through a resistor R3. When the display device is in the power-off mode, the first power supply is turned off, and the control device detects that the HPD signal is always kept at a low level.
The video signal transmitting unit 110 is connected to the state control register SCDC of the display device 20 through a DDC channel, and the control means 130 acquires the clock-locked state of the display device through the DDC channel. When the display device 20 is in the locked state, the display device 20 is in the on-mode, and when the display device 20 is in the unlocked state, the display device 20 is in the standby mode or the off-mode.
The control device 130 controls the operation state of the video playback apparatus by controlling the main power supply 120. When the control device 130 controls the main power supply 120 to be disconnected from the video signal transmitting unit 110, the video playing apparatus 10 enters a standby state; when the control device 130 controls the main power source 120 to be connected to the video signal transmitting unit 110, the video playing device 10 enters a power-on state.
Based on the video playing system shown in fig. 2, in an embodiment, as shown in fig. 3, there is provided a control method of a video playing device, including the steps of:
s302: detecting whether the display device is in a shutdown mode;
s304: if the display equipment is in a shutdown mode, controlling the video playing equipment to enter a standby state; if the display equipment is not in the shutdown mode, detecting whether the display equipment is in a standby mode or not;
s306: if the display equipment is in a standby mode, controlling the video playing equipment to enter a standby state; and if the display equipment is in the starting-up mode, controlling the video playing equipment to enter the starting-up state.
Based on steps S302-S306, detecting whether the display device is in a shutdown mode; if the display equipment is in a shutdown mode, controlling the video playing equipment to enter a standby state; if the display equipment is not in the shutdown mode, detecting whether the display equipment is in a standby mode or not; if the display equipment is in a standby mode, controlling the video playing equipment to enter a standby state; and if the display equipment is in the starting-up mode, controlling the video playing equipment to enter the starting-up state. According to the embodiment, the working state of the video playing device is controlled according to the working mode of the display device, when the display device is in the shutdown mode or the standby mode, the video playing device is controlled to enter the standby state so as to save electric energy, and when the display device is restarted to enter the startup mode, the video playing device is controlled to enter the startup state, so that user experience is improved.
In an embodiment, the detecting whether the display device is in the shutdown mode includes:
and acquiring a first voltage signal of the display equipment, and determining that the display equipment is in a shutdown mode when the first voltage signal meets a first voltage condition.
Specifically, if the video playing device detects that the HPD signal (the first voltage signal) is at a low level during normal communication, the control device determines that the display device enters a power-off mode, and switches the switch unit to a second state, at this time, the video playing device enters a standby state, and the control device controls the main power supply to be turned off.
In an embodiment, the detecting whether the display device is in standby mode comprises:
and acquiring a first voltage signal and a clock locking state of the display equipment, and determining that the display equipment is in a standby mode when the first voltage signal does not accord with the first voltage condition and the display equipment is in an unlocking state.
Specifically, when the display device is not in the shutdown mode, that is, the control device detects that the HPD signal is at a high level, and then determines whether the display device is in the standby mode according to the clock locking state of the display device. If the display equipment is detected to be in an unlocking state, the control device switches the switch unit to a second state, at the moment, the video playing equipment enters a standby state, and the control device controls the main power supply to be disconnected.
In an embodiment, when the video playing device is in a standby state, the method further comprises:
and acquiring a first voltage signal of the display equipment and a second voltage signal of the display equipment, and determining that the display equipment is in a startup mode when the first voltage signal does not accord with the first voltage condition and the second voltage signal accords with a second voltage condition corresponding to the startup mode.
When the video playing device is in the standby state, the switch unit is in the second state. It is thus possible to detect whether the display device is in the on-mode in combination with the first voltage signal and the second voltage signal.
Specifically, the control device detects that the HPD signal (first voltage signal) is at a high level, and the tmds_clk signal (second voltage signal) is at a high level, and determines that the display device is in the on mode. At this time, the control device switches the switch unit to the first state, and at this time, the video playing device enters the starting state, and the control device controls the main power supply to be turned on.
In an embodiment, when the video playing device is in a power-on state, the method further includes:
and acquiring a second voltage signal of the display equipment and a clock locking state of the display equipment, and determining that the display equipment is in a starting mode when the first voltage signal does not meet a first voltage condition and the display equipment is in the locking state.
When the video playing device is in a starting-up state, the switch unit is in a first state. It is thus possible to detect whether the display device is in the on-mode in combination with the first voltage signal and the clock-locked state.
Specifically, the control device detects that the HPD signal (first voltage signal) is at a high level, and the clock locking state is in a locked state, and determines that the display device is in the start-up mode. At this time, the control device controls the video playing equipment to keep working normally.
Based on the control logic, the video playing device can switch the working state along with the switching of the working mode of the display device.
In one embodiment, at the time of normal communication, the control device inquires the clock locking state of the display device through the DDC channel every set time, for example, every 1s.
In an embodiment, the first voltage signal and the second voltage signal need to satisfy respective durations in order to be able to more accurately detect the operation mode of the display device. For example, if the first voltage signal remains low for 3 seconds, the first voltage signal is determined to be low.
Fig. 4 is a schematic overall flowchart of a control method of a video playback device in an exemplary embodiment. As shown in fig. 4, the video playing device is in a power-on state, the HPD signal (first voltage signal) is detected every 1s, the detection time lasts for 3s, if the HPD signal is 0 (low level), the control device determines that the display device enters a power-off mode, the switch unit is switched to a second state, at this time, the video playing device enters a standby state, the control device controls the main power supply to be disconnected, if the HPD signal is 1 (high level), the clock locking state is continuously detected through the DDC channel, if the display device is detected to be in an unlocking state, the control device switches the switch unit to the second state, at this time, the video playing device enters the standby state, the control device controls the main power supply to be disconnected, and if the HPD signal is in the locking state, the HPD signal is continuously detected. After the video playing device enters the standby state, detecting the HPD signal and the TMDS_CLK signal (second voltage signal) every 1s, and controlling the video playing device to enter the start-up state if the HPD signal is 1 (high level) and the TMDS_CLK signal is 1 (high level).
