Embodiment
Hereafter by conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.
Fig. 1 is the schematic diagram of the set top box operations method according to the embodiment of the present invention.As shown in Figure 1, the method can comprise the steps:
Step S101: the power supply status detecting Set Top Box;
Step S102: detect HDMI-CEC power-on command.Wherein, can be under Set Top Box is in standby or off-mode, Set Top Box obtains the consumer electronics control CEC order of HDMI (High Definition Multimedia Interface) HDMI;
Step S103: power-on operation is carried out to Set Top Box.Wherein, when receiving CEC order for power-on command, Set Top Box can be started shooting.
In relevant technology, Set Top Box does not close HDMI module power supply when standby, and stand-by power consumption is larger.And when closing HDMI module power supply, then cannot receive HDMI-CEC signal, cannot realize thus and TV power supply state synchronized.The present invention is by detecting the state of Set Top Box, under Set Top Box is in standby or off-mode, Set Top Box obtains the consumer electronics control CEC order of HDMI (High Definition Multimedia Interface) HDMI, when receiving CEC order for power-on command, Set Top Box is started shooting, the problem synchronous with the power supply status of TV cannot be realized when solving set-top box standby, achieve Set Top Box under low-power consumption standby state and can automatically detect HDMI starting-up signal, thus complete Set Top Box and television set state synchronized, simplify user operation, enhance Consumer's Experience.
In preferred implementation process, Set Top Box can pass through the power supply status that integrated or external singlechip chip detects himself.Utilizing the pin access Set Top Box main power source of single-chip microcomputer, by judging that pin low and high level learns the power supply status of Set Top Box, achieving the function detecting Set Top Box power supply status.
In preferred implementation process, when receiving CEC order for power-on command, utilize single-chip microcomputer to access the main power source of Set Top Box, the pin of single-chip microcomputer, as control switch, can carry out power-on operation to Set Top Box.
In preferred implementation process, under Set Top Box is in standby or off-mode, Set Top Box can obtain the consumer electronics control CEC order of HDMI (High Definition Multimedia Interface) HDMI by single-chip microcomputer.
In preferred implementation process, standby power is separated with Set Top Box main power source and independently exists, and when set-top box standby, closes main power source.Standby power works, to the power supply such as single-chip microcomputer, HDMI module.
In a preferred embodiment, Set Top Box by single-chip microcomputer access HDMI-CEC communication interface, and passes through software receipt CEC power-on command.Standby power is powered to single-chip microcomputer, independently exists with main power source.Close main power source at standby mode, the overall power of Set Top Box can be ensured.But do not affect single-chip microcomputer work, under low-power consumption standby state, Set Top Box can detect HDMI starting-up signal automatically, the problem synchronous with the power supply status of TV cannot be realized when efficiently solving set-top box standby, also the power-on command from HDMI-CEC be can receive, thus Set Top Box and television set state synchronized achieved.
Fig. 2 is the particular flow sheet of the set top box operations method according to the embodiment of the present invention.This set top box operations method idiographic flow is as follows:

When Set Top Box detects HDMI-CEC communication signal, need the order determining whether television boot-strap.Single-chip microcomputer determines whether CEC power-on command according to the CEC message received, the more than concrete reference HDMI specification handbook of CEC power-on command.
(1) if not CEC power-on command, then return 203 continuation and detect HDMI-CEC power-on command.
(2) if CEC power-on command, step S205 is performed.
CEC information comprises a start bit and data bit.Data bit element can be the data of information, as logical address, CEC order or control bit, as information terminates [EOM] or response [ACK].
An and then transformation from low to high of transformation from high to low, and follow the sequential in Fig. 4, be exactly a start bit.
Fig. 5 is according to the embodiment of the present invention, the sequential chart of CEC logic state.As shown in Figure 5, the logic ' 0 ' that is respectively that data bit will be followed after start bit is timing requirements with ' 1 '.
Table 1 is the CEC frame structure according to the embodiment of the present invention.
As shown in table 1, we can find out that a concrete CEC order is become with n data packet group by a start bit, the structure of each packet fixedly comprises 10 bits, be made up of 8 data bit and 2 control bits, head packet comprises logical address and destination address, if and then EOM is logic ' 0 ', after expression, there is more data; If ' 1 ' then represents a frame or the end of message.
Table 1
Table 2 is the CEC packets according to the embodiment of the present invention.
As shown in table 2, EOM:Endofmessage, the end of ' 1 ' expression frame.ACK:Acknowledge, response bits: ' 0 ' represents response.
Table 2
Single-chip microcomputer judges it is start bit by the sequential detected on pin, data bit ' 0 ' or data bit ' 1 ', then does corresponding process according to the agreement of CEC according to frame structure identification CEC message of CEC.
Step S207: set-top-box opening.
Set Top Box detects the power-on command from HDMI-CEC, i.e. execution machine top box power-on operation.Single-chip microcomputer opens main power source start by switching on and shutting down module.The specifically switch of Single-chip Controlling Set Top Box main power source, is realized by single-chip microcomputer pin and interlock circuit, uses the pin of single-chip microcomputer as control switch, opens Set Top Box main power source, realizes set-top-box opening operation.
