Referring to Figure 1 and Figure 2, the preferred form number A0101 of the present invention, page 5 of a total of 17 pages, provides a television set 201210333. The processor 110 has a processor 11A and a high definition multimedia interface (HDMI) 120. The processor 110 is connected to a television set 20 by the HDMI 120. The processor 110 includes a transmitting module 10 The reading module is disconnected from the group 30 and the control module 4. It can be understood that the transmitting module, the 10-mouth module 20, the determining module 30 and the control module 40 can also be electrically connected to the child processor 110. The connection module is used as an external device of the set top box 100. [0009] The sending module 10 is configured to periodically send a read command to the television set 200, and transmit the HDMI 120 to the television set 200 to request the television set 200 to The processing device 110 transmits the data. When the television set 200 is in the working state, the television set 200 transmits an extended display identification material (EDID) to the processor 11 according to the read command. The EDID is a video electronic standard association ( VESA) Standard Information The formula ' contains the TV parameters, such as supplier information, maximum image size, color settings, vendor presets, frequency range limits, and TV string names and serial numbers, etc. When the TV 200 In the working mode, after receiving the read command sent by the transmitting module 10, the television 200 transmits the EDID to the processor 110 through the HDMI 120; when the television 200 is in the standby or power-off state, the television 200 does not send the same. The read signal sent by the module 10 reacts, that is, the EDID is not sent to the processor 110. In this embodiment, the HDMI 120 includes a transmission line supporting an I2C protocol, and the EDID is transmitted in a transmission line based on the I2C protocol. According to the I2C protocol, the EDID includes an acknowledgement code (ACK). Specifically, the EDID is a multi-byte information, and the ACK exists in a predetermined word position of the EDID, for example, the 8th bit. When there is an ACK, the value of the 8th word of the EDID is “Γ, otherwise "0" 099127521 Form No. A0101 Page 6 of 17 0992048360-0 201210333 - [0010] ο [0011] The renewing module 20 is used to read the slave television 200 when the television set 200 is in the working state. The feedback information transmitted through the HDMI 120 is output; when the feedback module 20 does not read the feedback information, the inter-signal signal is outputted to the determination pull group 30. In the embodiment, the feedback information is the EDID. In the mode, the reading module 20 includes a timing unit 21 and is pre-configured with an advance time. When the reading module 20 does not obtain the feedback information, the timing unit 21 first performs timing. When the time calculated by the unit 21 is equal to the predetermined time, the reading module 2 outputs the inter-signal signal to the judging module 30. It can be understood that the predetermined time can be determined according to specific needs, for example, 1.0 second _ ' or Other values. ο The edge determination module 30 is used according to the The feedback information and/or the idle signal determine the working state of the television 200. If the feedback information is obtained, it is determined that the television 200 is in a normal working state, and the determining module 3 outputs an activation signal; if the idle signal is obtained, the television 2 is judged. In the non-working state, the determining module 30 outputs a standby signal. Specifically, the determining module 3 determines that the reading module 20 obtains the feedback information by determining that there is an ACK in the EDID. For example, the determining information is twisted. 3 (i judges the 8th word of the EDID, if it is "j"', it indicates that the EDID includes ACK, indicating that the television 200 responds to the read signal sent by the transmitting module 1〇, and the television 200 is in normal condition. The working state 'the reading module 20 obtains the feedback information, the determining module 3 outputs an activation signal; when the television 200 is in the shutdown or standby state, the television 200 has no EDID output, and the reading module 20 outputs the idle signal. The signal, for example, the determination module 30 determines that the television 200 is in an idle state, and outputs a standby signal to the control module 40. [0012] 099127521 The control module 40 is configured to control according to the activation signal. TV set-top box 1〇〇Form No. A0101 Page 7/Total page 0992048360-0 201210333 [0013] [0015] [0015] Keep the working mode, or according to the standby position (4) The TV set-top box 1〇〇 enters the sleep mode. When the mode output is started, that is, when the television 2 is in the working state, the control module 40 controls the set top box to maintain the security mode, and the reading mode (4) (4) receives the E_ transmitted from the coffee machine 12 . It can be understood that the TV set top box can just include the working mode and the standby mode, and the control module 40 is connected with a switching unit (for example, 'programmable single chip microcomputer or software switch, etc., the picture is not connected'). The switching unit can be controlled according to the control unit. The modulo start signal or standby signal, just switch the TV_box to standby mode or working mode. The dance can be understood. When the TV set-top box switches to the standby mode, the transmitting module 10, the reading module 20, the determining module 30 and the control module 40 are all in working state, and the television set-top box is Other functional modules (such as audio/video processing modules, etc.) are in standby mode. The TV set-top box 100 automatically controls the set-top box 100 to be in the standby mode when the television set 200 is in the power-off state or the standby state according to the feedback information or the idle signal of the television set 200, and does not need to use the manual operation mode to control the set-top box 100 to enter the standby mode. Mode, avoiding wasting power due to human factors. Referring to Figure 3, the present invention also provides an automatic standby method for use in the set top box 100. The method comprises the following steps: Step S301, a read command is periodically sent and transmitted to the television set 200 by the HDMI 12. Step S303, when the television set 200 is in the working state, reading the feedback information output from the television set 2 and transmitted via the HDMI 120, when not reading 099127521 form number A0101 page 8 / total 17 page 0992048360-0 [ 0016] 201210333 [0017] [0019] [0019] When the feedback information is received, an idle signal is output. In this embodiment, the feedback information is the EDID, and the EDID includes an ACK. In addition, the television set top box 100 is preset with a predetermined time. When the set top box 100 does not obtain the feedback information, the set top box 100 performs timing, and when the calculated time is equal to the predetermined time, the idle signal is output. Step S305, determining the working state of the television set 200 according to the feedback information and/or the idle signal. If the feedback information is obtained, step S307 is performed to determine that the television 200 is in a normal working state, and outputting an activation signal; if an idle signal is obtained, executing In step S309, it is determined that the television 200 is in a non-operating state, and the standby signal is output. Specifically, it is confirmed that the back information is obtained by determining that there is an ACK in the EDID. For example, if the 8th word position of the EDID is judged, if it is "Γ", it indicates that the EDID is included in the EDID, indicating that the read signal sent by the television set 200 has responded, and the television set 200 is in a normal working state, and the set top box of the television set is 1〇〇. Obtaining the feedback information and outputting the activation signal; when the television 200 is in the shutdown or standby state, the television 200 has no EDID output, and the television set top box 100 outputs an idle signal, such as “0”, thereby determining that the television 20 0 is in the interspinning state. And outputting the standby signal to the control module 40. After the start signal is output, step S211 is executed, and the set-top box 100 is controlled to maintain the working mode according to the start signal. When the standby signal is output, step S213 is performed, and the television is controlled according to the standby signal. The set top box 100 enters a sleep mode. The set top box 100 of the present invention and the method thereof control the set top box 100 according to the operating state of the television set 200 such that when the television set 200 is off 099127521 Form No. A0101 Page 9 / Total 17 Page 0992048360-0 [0020] When the system is in the standby state of 201210333, the control module 40 controls the TV set top box 100 to automatically cut In the standby mode, when the television set 200 is in the normal working state, the set top box 100 works normally. Thus, when the user forgets to turn off the set top box 100 and the television set 200 is in the off state or the standby state, the control module 40 can be used. Forcing the TV set-top box 100 to be in the standby power-saving mode, avoiding waste of power due to human factors, energy saving and environmental protection.
