Embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
For technical solutions according to the invention are described, describe below by specific embodiment.
It should be noted that, in embodiments of the present invention, by remote controller manipulation television set, meanwhile, the clock that television set uses is provided by remote controller.In addition, because remote controller does not have screen, can only show to assist to adjust by means of television set the clock of real-time clock module in remote controller.
embodiment mono-:
Fig. 1 shows the first workflow of the clock correcting method that embodiment mono-provides, and for convenience of description, only shows the part relevant to the embodiment of the present invention.
A kind of clock correcting method, described clock correcting method comprises:
S11, television set obtains calibration clock;
S12, described television set calculates the clock difference of described calibration clock and present clock, described present clock by remote controller provide, described television set use clock;
S13, in the time that described remote controller receives the described clock difference of user's typing, described remote controller is calibrated the clock of described remote controller according to described clock difference.
In the present embodiment, described remote controller comprises real-time clock module, and this real-time clock module at least comprises real time clock circuit and clock register; Wherein, this clock register records the clock of described remote controller, and the clock of described remote controller is by described real time clock circuit real-time update.
In addition, television set is using described present clock as: used as television in broadcast program or from the internal clocking of the required use of Web search program.In addition, in the time of broadcast program, also need to use the progress of this internal clocking control broadcasting, for example: every a second of passing through internal clocking, play how many frame audio frequency and video.Under normal circumstances, the program of television for play mostly is real time programme (needing real-time update), thereby must use described present clock.
Like this, in the time that the clock of television set need to upgrade, for example, obtain calibration clock from outside (: network), television set is by poor to described calibration clock and described present clock, using difference as clock difference.And then, user can be on remote controller typing clock difference, the clock of clock register record is added the clock of this clock difference after calibration by remote controller.After, when television set needs re-synchronization clock, remote controller sends the clock after calibration to television set, and the clock after television set use calibration, as present clock, is realized the calibration of the clock of television set.
Preferably, the process of whole clock alignment all needs remote controller to send corresponding control command, and television set shows corresponding content according to this corresponding control command.For example: in the time that remote controller needs clock alignment, can receive the clock alignment instruction (being triggered by Macintosh default on remote controller) that remote controller sends, television set calls clock alignment function while receiving this clock alignment instruction; Again for example: in the time that user uses a teleswitch typing calibration clock, television set can show this calibration clock; Again for example: in the time that television set arrives calibration clock by Network Capture, television set can show this calibration clock; Again for example: treat that user uses a teleswitch after the complete calibration clock of typing, remote controller receives typing while confirming instruction (being triggered by programmable button on remote controller), described television set receives the clock after the calibration that described remote controller sends and shows.
Preferably, the described calibration clock that described television set gets is:
User uses the clock of described remote controller typing, or the World clock arriving by Network Capture (Coordinated Universal Time, UTC).
Wherein, the clock of user's typing, is specially: the clock that user provides according to the wrist-watch of wearing or other clock instrument this clock of the typing that uses a teleswitch.Particularly, enter in remote controller control that television set provides to time in application manually to time pattern after, television set can point out user to key in clock, user can use a teleswitch and directly key in clock.
In addition, in the situation that television set is networked, can directly obtain World clock by network (comprising: the Internet and mobile radio communication).
Separately preferably, because remote controller does not have Presentation Function, meanwhile, television set does not feed back to remote controller and adjusts the function of the clock of described remote controller to control remote controller.In addition, the described present clock using due to television set is that the clock of same remote controller keeps synchronous consistent.
If desired adjust the clock of described remote controller by television set sub remote controller, can obtain calibration clock by television set (comprising: user is by the clock of remote controller typing, or television set is by the World clock of Network Capture), and then it is poor and using difference as described clock difference that television set is made described calibration clock and described present clock.It should be noted that, this clock difference is numerical value, and this calibration clock and this present clock all adopt time format (for example: certain year is point certain second in some time in such a month, and on such a day).
Adjust the base unit that uses of clock difference because remote controller sends it to television set in advance, therefore, the base unit that the numerical value that television set calculates uses and remote controller are identical for the base unit of adjusting clock difference and using.And then until key in this numerical value on remote controller after, remote controller is adjusted the clock of the remote controller in clock register; Particularly, according to described numerical value with and the base unit that uses described numerical value is scaled to the clock of time format, then use the clock of described remote controller to add the clock of the remote controller in the clock refresh clock register after the clock that is scaled time format.What deserves to be explained is, the described time difference can be on the occasion of, can be also negative value, can also be zero; Correspondingly, each value of the clock of time format can be also on the occasion of or negative value or zero; For example: the time difference calculating is: 69 seconds, the clock of remote controller before not adjusting in clock register was: certain year is 1 second 1 point of some time in such a month, and on such a day, thereby the clock of the remote controller after adjusting in clock register is: certain year is 10 seconds 2 points of some times in such a month, and on such a day.
As another embodiment of the present invention, in the time need to using the present clock of the real-time clock renewal television set in described remote controller, can trigger clock transmission instruction by pressing default Macintosh; And then, once receiving this clock, remote controller sends instruction, from the clock register of real-time clock module, extract the clock of described remote controller, the clock of described remote controller is sent to described television set by wireless mode.The present clock of television set using the clock of the described remote controller receiving as this television set.
Preferably, remote controller by the clock of described remote controller by the infrared television set that is sent to; Television set receives the infrared signal of the clock that carries this remote controller by infrared remote receiver, and then from the infrared signal receiving, extracts the clock of described remote controller, and uses the clock of this remote controller as the described present clock of television set.
Thereby, by add real-time clock module in remote controller, realize in the time that television set need to use clock, remote controller sends the clock of described remote controller to television set, and then television set uses the clock of this remote controller as present clock, need to use the task (for example: see live telecast, see news, search from network the task such as audio frequency and video of certain time point) of clock to carry out.
Fig. 2 shows the second workflow of the clock correcting method that embodiment mono-provides, and for convenience of description, only shows the part relevant to the embodiment of the present invention.
As one embodiment of the invention, before described television set obtains the step of calibration clock, described clock correcting method also comprises:
S14, sends instruction if described remote controller receives the clock being triggered by default Macintosh, and described remote controller sends the clock of described remote controller to described television set, using described television set by the clock of described remote controller as described present clock.
Particularly, conventionally, remote controller has had multiple buttons, and common each button has been provided with corresponding function, if desired produce clock and send instruction, can adopt three kinds of modes: the first, on described remote controller, add new button (using this button newly adding as described default Macintosh), and set while pressing the button of new interpolation, trigger described clock and send instruction; The second, sets the function of the described clock transmission of this triggering instruction for a combination button (not being this combination button set-up function in the past) on described remote controller, and this combination button is described default Macintosh; The third, for certain button on described remote controller or certain function that the combination button of set-up function adds the described clock transmission of triggering instruction, and then, in the time of this button of user's touch-control or this combination button, send instruction and the described clock transmission instruction of the existing function of this button to described television set simultaneously, increase the function that this button or this combination button are described default Macintosh.
Like this, in the time that user presses described default Macintosh, can trigger described clock and send instruction, and then the processor that comprises of remote controller is when receiving this clock and sending instruction, from the clock register of remote controller, extract the clock of remote controller, and the clock of this remote controller is sent to television set by wireless mode.
Preferably, during for television boot-strap, the clock of described remote controller is sent to the situation of television set with the clock of renewal television set; If described remote controller receives the clock being triggered by default Macintosh and sends instruction, described remote controller sends the step of the clock of described remote controller to described television set, is specially:
If described remote controller receives the start-up command being triggered by starting key, described remote controller obtains clock from real-time clock module, the clock that sends described start-up command and get to described television set, receives the clock that described remote controller sends with described television boot-strap time.
Like this, when starting key above user presses remote controller, trigger start-up command; Thereby remote controller, according to presetting, once receive start-up command, just extracts the clock of described remote controller from clock register, and the clock of this start-up command and this remote controller is sent to television set simultaneously.Thereby, in the time that user presses starting key, when television boot-strap, receiving the clock that described remote controller sends, the present clock that is this television set by the clock setting of described remote controller, to adopt this present clock to carry out tasks such as playing real time programme.
Preferably, the clock of described start-up command and described remote controller adopts same information recording, just by the clock log of described start-up command and described remote controller in different field.Thereby television set basis is made an appointment with remote controller, extracts the clock of described start-up command and described remote controller from corresponding field.
As one embodiment of the invention, described in the time that described remote controller receives the described clock difference of user's typing, described remote controller is calibrated the step of the clock of described remote controller according to described clock difference, be specially:
After treating that described remote controller receives the described clock difference of user's typing, if receiving typing, described remote controller confirms instruction, calibrate the clock of described remote controller according to described clock difference, send the clock after calibration to described television set, show the clock after described calibration with described television set.
Particularly, after television set calculates described clock difference and shows, user can be according to the described clock difference of the described clock difference typing number format in described remote controller showing; After treating the complete described clock difference of user's typing, confirm instruction (user presses corresponding Macintosh and triggers) if remote controller receives typing, use the clock in this clock difference calibration clock register, send the clock after calibration to television set; Television set demonstrates the clock after calibration, incorrect if user finds calibration result, can re-execute the clock correcting method that the embodiment of the present invention provides; Wherein, the incorrect reason of calibration result comprises: because remote controller does not have Presentation Function, when user operates, may have misoperation; The accidental disconnection of the communication connection of remote controller and television set, causes partial data to be lost.
Like this, the clock after calibration is sent to television set by remote controller, and television set demonstrates the clock after calibration, judges whether to need to recalibrate according to the clock demonstrating with user.
As a kind of embodiment of the present embodiment, first start the menu bar of television set, to select from this menu bar time application, this to time application have two kinds to time mode: the first, need user's typing calibration clock, then this to time computation go out the clock difference of described present clock and described calibration clock; The second, for example, if television set has been connected to network (: the Internet or mobile radio communication), can by this to time apply directly from Network Capture World clock, then using this World clock as described calibration clock, then adopt this to time computation go out the clock difference of described present clock and described calibration clock.
Wherein, it should be noted that, the form of described calibration clock is: certain year is point certain second in some time in such a month, and on such a day; Preferably, described calibration clock can be accurate to Millisecond.
Thereby, for the first to time mode, because remote controller does not have Presentation Function, do not there is the described calibration clock of the above-mentioned form of typing yet; Thereby the calibration clock of the typing that uses a teleswitch, can only demonstrate the calibration clock with above-mentioned form by television set, and calculate described calibration clock by television set and deduct the clock difference obtaining after described present clock.
For the second to time mode, due to from Network Capture to World clock originally just met above-mentioned form, can be directly using this World clock as calibration clock, therefore, can directly World clock and the described present clock getting be done to differ to obtain clock difference.
Separately it should be noted that, state calibration clock and deduct in the computational process of described present clock, described present clock and described calibration clock all need to be scaled take time point or second as the numerical value of base unit.For example: described present clock and described calibration clock are all scaled to numerical value in seconds.And then the clock difference calculating is a numerical value (not in such a month, and on such a day the some time was divided the clock form of certain second in certain year).
And then, user can manipulate the button of remote controller to start the time adjustment function of remote controller, simultaneously, television set can show that the interface of this time adjustment function is (by the time adjustment function interface of television set display remote controller, can guides user operate, and whether the typing of checking numerical value is correct or carry out correspondingly numerical value adjustment), and then, user can on remote controller, directly key in this numerical value and select its use base unit (television set can show the numerical value that user keys in, and the process of base unit is selected in demonstration), when user presses (television set can be pointed out: user has confirmed the numerical value of keying in) after acknowledgement key, remote controller is adjusted the clock (television set can show the prompting that the clock of remote controller is adjusted) of the remote controller in clock register according to the base unit of this numerical value and use thereof, and then in the time that television set needs refresh clock, remote controller sends the clock of described remote controller to television set, thereby realize the calibration of the clock of television set.
