And in the way of follow-up claim not difference by title is used as distinguishing assembly, but with assembly difference functionally
It is used as the criterion distinguished." comprising " mentioned in the middle of description and follow-up claims in the whole text is an open use
Language, therefore " comprise but be not limited to " should be construed to.Additionally, " coupling " word comprises at this and any directly and is indirectly electrically connected
Means, therefore, if a first device is coupled to one second device described in literary composition, then representing this first device can directly be electrically connected
In this second device, or indirectly it is electrically connected to this second device by other device or connection means.
Refer to the schematic diagram that Fig. 1, Fig. 1 are the first network device 100 according to one embodiment of the invention.As it is shown in figure 1,
First network device 100 includes system 110, HDMI video signal mac function 120, HDMI mac function 130,
Network function block 140 and a HDMI socket 150, wherein system 110 includes at least one processor 122, and first network
Device 100 is coupled to one second network equipment 170 by a HDMI transmission line 160.Additionally, in the present embodiment, first network
Device 100 meets 1.4 editions specifications of HDMI, but the present invention is not limited thereto.
In the operation of first network device 100, HDMI video signal mac function 120 is used to transmit video signal data to second
Network equipment 170；HDMI mac function 130 is used for being responsible for the transmission of some interfaces, such as display data channel
The control of (Display Data Channel, DDC) and consumer electronics (Consumer Electronics Control,
CEC) etc.；Network function block 140 then comprises the operation of network function.Additionally, HDMI video signal mac function 120, HDMI
Mac function 130 and network function block 140 can be integrated among a chip, and utilize chip internal each other
Bus transmits data；If it addition, HDMI video signal mac function 120 and network function block 140 are made in two not respectively
In same chip, the most each chip comprises interface function block respectively, and makees to link communication by CEC information.
Refer to the schematic diagram that Fig. 2, Fig. 2 are the network advertisement device 200 according to one embodiment of the invention.As in figure 2 it is shown,
Network advertisement device 200 is a part of parallel circuit in HDMI mac function 130 and network function block 140, and net
Network notice device 200 includes clock generator 210, enumerator 220 and a CEC interface control circuit 230.Additionally,
In the present embodiment, clock generator 210 be a digital control oscillator (Digital Controlled Oscillator,
DCO), and enumerator 220 is a ripple counter (Ripple Counter), but the present invention is not limited thereto.
In the operation of first network device 100 and network advertisement device 200, first, when first network device 100 with
Second network equipment 170 carry out online after, first network device 100 can by the DDC function in HDMI mac function 130
Obtain physical address (physical address), and obtain ability discovery and control by CEC function and the second network equipment 170
System (Capability Discovery and Control, CDC) agreement.Then, as HDMI Ethernet channel (HDMI
Ethernet Channel, HEC) be enabled after, network function block 140 just can begin through Ethernet channel transmit with
Receiving network package, now, a notification instruction (NotifyAlive) is pre-deposited in CEC interface control circuit 230, and meter
Number device 220 is activated.Enumerator 220 can continue to count according to a clock signal clk produced by clock generator 210, and
Periodically just produced triggering signal Vtri to a CEC interface control circuit 230 every 60～65 seconds, to trigger CEC interface control
Circuit 230 processed transmits notification instruction (NotifyAlive) to the second network equipment 170.
In the present embodiment, clock generator 210 and enumerator 220 when operation independent of the processor in system 110
112, and clock signal clk produced by clock generator 210 is different from the system clock that processor 112 is used.Therefore,
When the processor 112 in first network device 100 operates in a sleep pattern, processor 112 in system 110 and other
The circuit that can be not required to work can not carry out any operation or close (power off), to reduce static power consumption, and is
In system 110, at least one of system clock can also be turned off to reduce dynamic power consumption.And sleep when processor 112 operates in one
During sleep mode, in network function block 140, the circuit of some maintains running, with responsible monitoring from HDMI transmission line 160
Packet data to decide whether to wake up up whole system, and network advertisement device 200 still can normal operation periodically to transmit
Notification instruction NotifyAlive is to the second network equipment 170, so that the HEC function of first network device 100 is maintained at effectively
State.
It is as noted previously, as network advertisement device when operation independent of the processor 112 in system 110, therefore processes
Device 112 can not carry out any operation in a sleep mode, more effectively to reduce power consumption.
Refer to Fig. 3, Fig. 3 is the network advertisement being applied to a first network device according to the present invention one first embodiment
The flow chart of method.With reference to Fig. 1～3, flow process is described below:
Step 300: provide a first network device to be coupled to one second network equipment.
Step 302: store a notification instruction.
Step 304: produce a clock signal.
Step 306: count according to this clock signal, periodically to produce a triggering signal to trigger this notice of transmission
Instruction is to this second network equipment, and what the processor during wherein this clock signal is different from this first network device was used one is
System clock.
The brief summary present invention, in the network advertisement device and network notification method of the present invention, when network equipment enters
When entering a sleep state, persistently the network function of network equipment can be tieed up under the situation that processor and system clock are closed
Hold in effective state, therefore, it can really reduce the power consumption of network equipment.
The foregoing is only embodiments of the invention, all equalizations done according to the claims in the present invention change and modify, all
The covering scope of the present invention should be belonged to.
