Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with attached drawing to the present invention make into
It is described in detail to one step, it is clear that the described embodiments are only some of the embodiments of the present invention, rather than whole implementation
Example.Based on the embodiments of the present invention, obtained by those of ordinary skill in the art without making creative efforts
All other embodiment, shall fall within the protection scope of the present invention.
Embodiment 1:
Fig. 1 is a kind of decoding process schematic diagram of decoding card provided in an embodiment of the present invention, and concrete implementation method includes:
S101: itself each video output interface status signal corresponding with display is obtained.
A kind of coding/decoding method of decoding card provided in an embodiment of the present invention, is applied to decoding card, which includes one
Or multiple video output interfaces that can be connected with display.
Specifically, in embodiments of the present invention, it is corresponding with display that decoding card obtains itself each video output interface
Status signal, which, which can be, identifies the status signal whether video output interface connects display, is also possible to
The display being connect with video output interface status signal whether in the open state.
The process that decoding card obtains status signal belongs to the prior art, in embodiments of the present invention to the process without superfluous
It states.
S102: it according to each status signal, judges whether there is and is connected with video output interface and is in opening state
Otherwise the display of state, carries out S104 if it does not exist, then carrying out S103.
Specifically, when decoding card gets itself video output interface and whether connects the first state signal of display,
According to the first state signal, judge whether each video output interface is connected with display, if each video output interface
All no connection displays, then there is no be connected and display in the open state with video output interface.
Believe when decoding card gets the display that connect with video output interface the second state whether in the open state
Number when, according to the second status signal, judge whether there is display in the open state, if it does not exist, then there is no with
Video output interface is connected and display in the open state.
S103: enter power and energy saving mode.
In embodiments of the present invention, it is not connected with display when decoding blocks, or the display of decoding card connection is in closing shape
When state, decoding card enters power and energy saving mode.Specifically, when decoding blocks not connected display, or the display of decoding card connection
When being in close state, decoding card will work before data storage in memory, power supply continue to for memory etc. it is most necessary
Equipment power supply, to ensure that data are not lost, and decode card in other modules be in closed state, decode the power consumption of card at this time
It measures extremely low, and is no longer decoded operation, can effectively reduce waste of the decoding card to electric energy in this way.And once decode card
When detecting the display accordingly connecting with itself signal in the open state, data are read from memory at once and are restored to
Working condition before the mode of power and energy saving.The method that decoding card enters power and energy saving mode and exits power and energy saving mode belongs to
The prior art, in embodiments of the present invention to the process without repeating.
Specifically, decoding, which blocks, to be entered when there is no being connected with video output interface and display in the open state
Power and energy saving mode.
Such as: decoding card is currently connected with 2 displays, and 2 displays are detected all in closed state, decoding card
There is no display in the open state, decoding card enters power and energy saving mode, reduces power consumption.
S104: operation is decoded to the video code flow received.
Specifically, being connected with video output interface and display in the open state when existing, needs to decode card and carry out
Normal decoding operate, the video code flow that decoding card docking receives are decoded operation.
Since in embodiments of the present invention, decoding card obtains itself each video output interface state corresponding with display
Signal judges whether there is display and connect with itself and in the open state, if entering power and energy saving mode, because
This can effectively reduce waste of the decoding card to electric energy, and in addition because decoding jam is loaded on main control device, decoding card enters
After the mode of power and energy saving, main control device can unload decoding and block occupied resource, to further save main control device
Resource, and save the power consumption of main control device.
Embodiment 2:
In embodiments of the present invention in order to avoid main control device continues to send view to the decoding card for entering power and energy saving mode
Frequency code stream causes the waste of main control device process resource, on the basis of above-described embodiment 1, works as solution in embodiments of the present invention
Code sticks into when being advanced into power and energy saving mode, the method also includes:
The information that itself enters power and energy saving mode is sent to main control device, main control device is made to stop sending view to itself
Frequency code stream.
Specifically, decoding card enters after the mode of power and energy saving, the information that itself enters power and energy saving mode is sent to
Main control device, main control device receive decoding and block into after the information of power and energy saving mode, stop sending video codes to decoding card
Stream, so that the resource of main control device can also be saved to a certain extent.
Embodiment 3:

Specifically, being standardized according to HDMI, the level magnitude of HDMI data-signal can quilt at display end when display is opened
50 Ohmic resistances draw high 3.3V, and the level magnitude of HDMI data-signal can become 0V when display is in close state.It is logical
Whether the level magnitudes for crossing the HDMI data-signal for the display that judgement is connect with itself each video output interface are greater than setting
Threshold value, the threshold value are debugged and are set according to the actual situation, as long as the threshold value can accurately distinguish the switch shape of display
State.When the level magnitude of each HDMI data-signal is no more than given threshold, judgement is not present and video output interface
Connected and display in the open state.The level magnitude for passing through HDMI data-signal in embodiments of the present invention determines aobvious
Show that the switch state of device belongs to the prior art, in embodiments of the present invention to the process without repeating.
In embodiments of the present invention, it is connected with video output interface in order to more accurately judge whether there is and is in unlatching
The display of state, on the basis of above-described embodiment 1, when the status signal includes HOTPLUG signal and HDMI data letter
Number when, it is described according to each status signal, judge whether there is and be connected with video output interface and in the open state
Display includes:
For each HOTPLUG signal of acquisition, the height of each HOTPLUG signal is judged；
When existing for high HOTPLUG signal, the display connecting with itself each video output interface is judged
Whether the level magnitudes of HDMI data-signal are greater than given threshold；
When the level magnitudes of each HDMI data-signal are not more than given threshold, then there is no connect with video output for judgement
Mouth is connected and display in the open state.
Specifically, for each video output interface by the height to each HOTPLUG signal to determine whether in the presence of
The display being connect with video output interface, when exist connect with video output interface display when, by judgement each with
Whether the level magnitudes of the HDMI data-signal of the display of itself video output interface connection are greater than given threshold, when each
When the level magnitudes of HDMI data-signal are not more than given threshold, then there is no be connected with video output interface and be in opening state
The display of state.
