In addition, device system development The focus is on how to save power (power consumption reduction) and cost savings. Therefore, power-saving and low-power technologies are often one of the factors considered by customers. In order to meet the demand of low power consumption, power-saving mode and wake-up mechanism遂 Gradually become a priority for the device system. Please refer to the first figure, which shows a schematic diagram of a conventional signal transmission device. The signal transmission device system comprises a transmitter 11, a receiver 12 and a signal transmission line 13. Current source The mode transmitter 11 further includes a current source 1U and a switch D&D. The receiver 12 is coupled to a power supply AVcc, and the receiver 12 includes a receiving circuit (differential amplifier) and a two-resistor RTA RT, and two resistors. RT and RT' are respectively connected to the signal transmission line 13. Under this conventional architecture, if the receiver 12 enters the power saving mode (Indicating that the receiving circuit has been disabled), however, the power supply AVcc of the receiver 12 will still follow the two-resistance and Rt, and the signal transmission line 13 to the ground of the current source mode transmitter 11, in other words, even if the receiver 12 has entered the power saving mode 'The entire conventional signal transmission device will always provide current to the signal transmission line 13' and cause the receiver 12 to enter the power saving mode 'but still consumes power. Mai's reason' application In view of the lack of the prior art, the idea is to use a method of turning off the receiver blade circuit to reduce the power loss, and the method of starting the receiver circuit 4 201101015 by detecting the signal to wake up the system, so that the system can resume normal operation. The mode further invents the "power saving and calling-method" of the present invention to improve the lack of the above-mentioned conventional means. [Abstract] The performance of the present invention is that the power consumption in the non-woven system is reduced, and the cost is reduced. The signal monitoring means can (4) start the circuit to meet the needs of the user, so the function of the power saving and wake-up mechanism of the present invention is provided. The present invention provides an application for the above purpose. A wake-up method of a power-saving mode of a signal receiving device, wherein the signal receiving device has a - channel and a second channel, the method includes at least the following steps: in the power saving mode, starting the The _ channel of the beta function, and detects whether a first signal is normal, when the first signal is not normal, the signal receiving device maintains the power saving mode operation; and in the province Lai and #第第- When the signal is normal, the detection function of the second channel is activated, and it is detected whether a second signal is normal. When the second signal is abnormal, the signal receiving device is maintained in the power saving mode. - According to the above purpose In another aspect, the present invention provides a signal receiving apparatus, including: a receiving circuit for receiving at least one output signal from the at least one channel; and a control circuit coupled to the receiving circuit for detecting the at least one The at least one output signal of the channel is configured to generate a control signal according to the detection result; and a control switch is located between the power source of the signal receiving device and the at least one channel The control-apart relationship by the control of the control circuits in order to determine whether to disconnect the power to the signal receiving means of the at least connected to a passage to avoid the signal current receiving means of the inflow or outflow of the at least one channel according to the control signal. According to the above object, another aspect of the present invention provides a control method for a signal receiving device for receiving a transmission signal from at least one channel, the method comprising: detecting the at least one channel from the channel At least one output signal, and generating a control signal according to the detection result; and determining, according to the control signal, whether to disconnect the power supply of the signal receiving device from the at least one channel to avoid current flowing into the signal receiving device or The at least one channel flows out. 5 201101015 [Embodiment] The present invention will be fully understood by the following examples, so that those skilled in the art can implement the present invention without being limited by the following embodiments. Referring to FIG. 2, a block diagram of a power saving and wake-up device of the differential signal receiving device of the present invention is shown. The receiving device includes a power supply, and the receiving device includes a receiver 2 and a control circuit 21. And a subsequent stage circuit 22. The receiver 2 further includes an impedance pair 2 such as a resistor-switch pair 202 and an amplifier 2〇3. The receiver 2 receives an input signal S from the transmission _, and amplifies the amplifier 203 to generate an output signal I, and the subsequent circuit 22 receives the output signal S〇UTa for subsequent processing. At the same time, the control circuit 21 also receives the output signal s(10) and detects whether the output signal S0U4 is normal. When the detected coffee is not normal, the control circuit 21 outputs a control signal (to disable/enable other circuits), causing the two switches 2〇2 to open (〇pEN), so that the power supply AVcc of the receiver 20 cannot be followed. The two resistors and Rt, and the signal transmission line 13 are led to the ground of the sneak 11; in other words, the money of the lining is not enough for the signal transmission line I3, so that the receiving device of the channel will no longer consume energy ( That is, entering the power saving mode of the present invention, those skilled in the art should be able to easily know that the second switch and the amplifier 2G3 can be controlled by the control signal at the same time or separately by the other (4). In the power saving mode, when the system is separated - a predetermined time interval (which may be a fixed or a defined time _) after the start_function. One of the embodiments of the start_function is that the control circuit 21 simultaneously controls the two switches 2〇2 to become conductive (〇Ν) and the control amplifier 24 is Enable state, and determine whether the input signal & normal, so that other circuits of this channel (such as the latter circuit) or / and other circuits of other channels should enter the start function or normal operation mode. example The impedance pair 201 (for example, a resistor) and the function of the switch pair 202 can be implemented with only one transistor pair. In the case of a positive tilt and a start-up function, the gate voltage of the transistor pair is controlled to generate a -impedance. Value; in the money mode, the transistor pair is in the form of a switch pair, bribe the connection (4) 2Q of the money AVee and the Yanlin line 13 6 201101015 between the _ _ _ _, due to the input signal The format or characteristics of SIN will be different according to different interface standards == so the implementation of the _ control circuit will be decorated according to the input signal. In this manual, only the input is reduced by SlN. For the clock signal and the data afl number for the description.

In this case, the control circuit 21 further includes a first price detector 211 and a second side device 212. The receiver 2 receives the -clock pair signal SiN from the current source mode transmitter 11 and amplifies and outputs a signal U through the amplifier 2〇3, and then transmits the path to the subsequent stage circuit 22 in a three-path transmission for subsequent processing. The path is transmitted to the first detector 211 to detect the clock pulsation signal, and the path is transmitted to the second detector us. The second detector 212 is based on the reference clock to detect a clock fresh signal. When the detected signal is abnormal, the control circuit 21 outputs a control signal (enable/disable signal), causing the switch 23 to be an open circuit (OPEN), so that the current clock is re-consumed (ie, entering the present mode). In another embodiment, if only the detection of the jitter of the clock signal is normal, the first detector 211 and the second detector 212 may be omitted.

After being decoded, it is sent to the third detector 312 to detect whether at least its -subtractive or negative f,# is detected by its horizontal sync signal (HS), vertical sync signal (VS), or thief capable signal (DE). When the signal is not normal, the control circuit 31 #output-control signal (disable or enable signal) causes the two switches 302 to be open (OPEN), so that the data channel is no longer energy-consuming (ie, enters the power-saving mode of the present invention) ). 7 201101015 When the input signal S1N includes a clock signal and a data signal, the receiving device includes a -0 shirt channel receiver 2G and at least a data channel receiver 3A. - Real reward t, by the clock circuit receiver 200 control circuit 2j for controlling the disable (power saving mode) or enabling (normal mode) of all channels separately or simultaneously. In another embodiment, (4) the control circuit of the if-channel receiver 30 is used to enable or enable all of the channels (4), respectively or simultaneously. In another embodiment, the control circuits (21, 31) of the receivers (2, 30) of each channel are used to individually control the disable or enable of each channel. △With the above-mentioned related clock enable signal and / or three color (R / G / B) data enable signal caused by the action and disable action 'software control or hardware or a mixture of the two technologies The means are achieved, and those skilled in the art can easily accomplish it. &See Fig. 4' is a machine diagram showing the power saving and waking method of a signal receiving apparatus of the present invention.
