Abstract
The invention provides a television signal identification method and a television. Under a state of a television channel, a processor receives a synchronous signal sent by a signal receiver; the processor detects the synchronous signal, namely, detects whether the synchronous signal exists; and if the processor detects that no synchronous signal exists, the processor sends a data initializing command to the signal receiver, and restarts the signal receiver. Therefore, the television can automatically recover the state that a user watches the television normally when the power is abruptly switched off and then the power supply is recovered, and brings convenience for the user to watch the television.
Description
Technical field

Wherein, described initialization unit also comprises: information transmitting unit is used for the operation information to described signal receiver transmission user.
Wherein, described processor also comprises: judging unit is used to judge whether described television set is in television channel.
Beneficial effect of the present invention is: the invention provides a kind of TV signal recognition methods and television set, by the synchronizing signal under the normal operating conditions of processor monitors signal receiver, if there is not this synchronizing signal, then in time with this signal receiver initialization, so that this television set can be in sudden power, when recovering power supply then, recover the state that the user normally sees TV automatically, see that to the user TV has brought convenience.
Description of drawings
The TV signal recognition methods flow chart that Fig. 1 provides for the embodiment of the invention;
The TV structure schematic diagram that Fig. 2 provides for the embodiment of the invention.
Embodiment
The invention provides a kind of TV signal recognition methods and television set, under the television channel state, the synchronizing signal that processor received signal receiver sends; Processor detects described synchronizing signal, detects to have or not described synchronizing signal; Detect no described synchronizing signal if state processor, described processor sends the data initialization order to described signal receiver, restarts described signal receiver.So that this television set can when recovering power supply then, recover the state that the user normally sees TV automatically in sudden power, see that to the user TV has brought convenience.
For making purpose of the present invention, technical scheme and advantage clearer, clear and definite, below develop simultaneously with reference to accompanying drawing that the present invention is described in more detail for embodiment.
Fig. 1 is the TV signal recognition methods that the embodiment of the invention provides, television set comprises the signal receiver that is used to receive, discern, handle various information processing devices and is used to receive extraneous TV, satellite-signal, the control of this signal receiver receiving processor, control according to this processor receives different TV, satellite-signal, signal as different TV stations, send the signal that receives to processor then, the treated device of this signal is handled the back and is played back by display on the television set and audio amplifier.This TV signal recognition methods comprises step:
101, judge whether television set locates television channel.
Television set generally comprises television channel and DVD passage, and when the television for play TV signal, this television set just is in television channel.
If 102 television sets are under the television channel state, the synchronizing signal that processor received signal receiver sends.
If television set is when playing TV signal normally, processor obtains a lasting signal and keeps synchronous synchronizing signal as this processor and this signal receiver according to the various signals (as: TV signal) that signal receiver sends.
103, processor detects described synchronizing signal, detects to have or not described synchronizing signal.
Processor monitors described synchronizing signal, monitor whether this synchronizing signal is normal, promptly have or not described synchronizing signal, to monitor whether operate as normal of this signal receiver, if do not detect this synchronizing signal, then do not have TV signal on this signal receiver, then television set may also may be that TV signal is very weak suddenly at this moment by the instant shut-in machine.
104, carry out timing to detecting the time that has or not described synchronizing signal.
At this moment, in order to prevent it is the very weak synchronizing signal that causes processor not detect signal receiver of this TV signal this moment, then carry out timing to detecting the time that has or not described synchronizing signal, so that the interruption of judging this synchronizing signal according to the time of presetting is owing to television set is caused by the instant shut-in machine, still extraneous TV signal causes a little less than too, as set timer continuous 10 times for detecting synchronizing signal, think that then the synchronizing signal that television set is caused by the instant shut-in machine interrupts.
If 105 in the time of presetting, described processor detects no described synchronizing signal, described processor sends the data initialization order to described signal receiver, and sends user's operation information to described signal receiver, restarts described signal receiver.
Processor comes refresh signal receiver again by initialization command and operation information, restarts described signal receiver, and this signal receiver is returned to by the operating state before the instant shut-in machine, and the user can see TV programme normally.Wherein, comprised by user's operation information: television set is by the program number before the instant shut-in machine, frequency etc.Do not need user's switch television set again, television set just can return to by the TV programme state of normally seeing before the instant shut-in machine.
Accordingly, the embodiment of the invention also provides a kind of television set, as shown in Figure 2, comprises processor 110, signal receiver 120, and wherein, described processor 110 comprises signal receiving unit 111, detecting unit 112, initialization unit 113, wherein:
Described signal receiving unit 111 is used under the TV running status, the synchronizing signal that received signal receiver 120 sends;
Described detecting unit 112 is used to detect described synchronizing signal;
Described initialization unit 113 if be used for sending the data initialization order to described signal receiver when stating detecting unit 112 and detect no described synchronizing signal, restarts described signal receiver.
Further among the embodiment, described processor 110 also comprises:
Further among the embodiment, described initialization unit 113 also comprises: information transmitting unit 115 is used for the operation information to described signal receiver transmission user.
This television set does not need user's switch television set again by the instant shut-in machine time, television set just can return to by the TV programme state of normally seeing before the instant shut-in machine.
It should be noted that, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technical scheme of the present invention, and not breaking away from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
