Abstract
A method for saving electricity in cable and radio TV system includes driving each component as normal to let TV be state for viewing if viewing TV program by user is detected by infrared transducer when power is on, switching power of video subsystem and audio subsystem off to let whole system be switched over on sleep mode if viewing TV program by user is not detected out, switching whole system over on pause mode if viewing TV program by user is not detected out or no any command signal is inputted within set time.
Description
Technical field
The present invention relates to by wired and wireless network receive and transmission from the power-saving technique of the wired and wireless television system of the information flow of Server Transport.Specifically, about the power-saving method of the wired and wireless television system that do not prevent to consume unnecessary power consumption as the user during TV reception.
Background technology
Common television system can be by antenna or cable receiving broadcast signal and TV reception in fixed place.In contrast to this, even be installed in also can TV reception in moving on the equipment such as vehicle for the wired and wireless television system of researching and developing out recently.Therefore, in general, wired and wireless television system can use battery supply in moving.
For original wired and wireless television system, if in the time of having set user's input instruction signal not, judge that then the user does not have TV reception.Simultaneously, system is converted to standby or sleep pattern, thereby just can prevents to have consumed unnecessary electric power.
Summary of the invention
To achieve these goals, realize its purpose according to wired and wireless television system power-saving method of the present invention by following several stages: after the opening power, if detected the user at TV reception then make each parts driven of system by infrared ray sensor, thereby made TV be in the 1st stage of the state of can watching; In the above-mentioned stage, if do not detect the user at TV reception then switch to standby mode.Then, if detect the user at TV reception with interior by above-mentioned infrared ray sensor, then make TV be in the state of to watch in the time of setting.If do not detect the user, then with the dump of subsystem of video and audio subsystem at TV reception.Thereby whole system is switched to the 2nd stage of sleep pattern; Under above-mentioned sleep mode state,, then drive subsystem of video and audio subsystem and make TV be in the state of to watch if the time of having set detects the user by above-mentioned infrared ray sensor and imported command signal at TV reception or user with interior.If do not detect the user at TV reception or do not import any command signal, then whole system switched to the 3rd stage of park mode; Under above-mentioned park mode state, if the user presses power knob, then make power supply opening, and to make system restoration be the 4th stage of initial condition.
As mentioned above, the present invention detects the situation of user's TV reception by utilizing infrared ray sensor and power management timer, does not have TV reception if detect the user, then television system is switched to standby mode.Then, still do not have TV reception if detect the user, perhaps the user does not have input instruction signal, then television system is switched to sleep pattern.Like this, just can there be the situation of TV reception correctly to detect to the user.Simultaneously, according to detection case television system is switched to standby mode or sleep pattern, thereby can prevent the waste of electric power.This is the good result that the present invention has.
Description of drawings
Fig. 1 be in the power-saving method of wired and wireless television system of the present invention each the processing stage signal flow graph.
Embodiment
Below, the embodiment the economize on electricity of the present invention of the 1 pair of foundation processing stage is described in detail with reference to the accompanying drawings.
Be divided into 3 kinds according to power saving management pattern of the present invention.First kind of pattern be for can watch pattern, i.e. the pattern of user's TV reception, and it is to the various piece supply power of television system and makes the pattern of various piece driven.Second kind of pattern is standby mode, promptly only with the state of the dump of subsystem of video (for example: display device controller, back lighting device etc.) and audio subsystem.Like this, under the standby mode state, just make mpeg processor and communication network Connection Card (NIC:Net Interface Card) driven immediately when having imported command signal to the user TV reception or user, thereby television system is converted to the pattern of can watching by infrared ray (IR) sensor.The third pattern is a sleep pattern.The power supply that is about to the various piece except that memory all cuts off, thereby guarantees that power consumption reaches minimal pattern.
At first, after power supply opening, then drive infrared ray sensor with wired and wireless television system.By this stage, if detect the user, then make the various piece driven of system at TV reception, thereby being in, television system can watch state S1-S3.
But in the above-mentioned stage, if do not detect the user at TV reception by infrared ray sensor, system will give electric power controller (Powermanager) with this intelligence aids.At this moment, above-mentioned electric power controller will make the operation of standby timer.Then, above-mentioned timer calculates the value of having set.In the meantime, whether the user is confirmed in the detection case of TV reception.If inspection is less than the user at TV reception, then by the above-mentioned stage, make the various piece driven of system, from but television system is in can watch state S4, S5.
But, above-mentioned standby timer is carrying out the computing interval (expire) to all values of having set, if do not detect the user at TV reception by above-mentioned infrared ray sensor, then cut off the power supply of subsystem of video and audio subsystem, and make the in running order S6 of sleep timer, S7.
Then, above-mentioned sleep timer calculates the value of having set.In the meantime, to detecting the user by above-mentioned infrared ray sensor whether in the situation of TV reception, perhaps user's situation of whether having imported command signal is confirmed.If detect the usefulness user at TV reception by above-mentioned infrared ray sensor, perhaps the user has imported command signal, then drives subsystem of video and audio subsystem, can watch state S8-S10 thereby television system is in.
But, above-mentioned sleep timer is before the value that finishes that all have been set is calculated, do not import any command signal if detect the user at TV reception or user by above-mentioned infrared ray, above-mentioned electric power controller then will be except that memory the power supply of various piece all cut off, thereby be park mode S11 with current mode switch.
Then, whether the user is pressed the situation of power knob and confirm, do not press power knob, then continue to keep above-mentioned park mode if distinguish the user.Supressing power knob if distinguish the user, then with power supply opening, is initial condition S12 thereby make system restoration, S13.
As a reference, above-mentioned infrared ray sensor is arranged on the position, front of TV, thereby can makes it, can the situation of user's TV reception be detected as normally used people's detecting sensor.
By above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.Therefore, the technical scope of this invention is not limited to the content on the specification, must determine its technical scope according to interest field.
