Description of the main element symbols:
the following detailed description will further illustrate the invention in conjunction with the above-described figures.
Detailed Description
To facilitate an understanding of the invention, the invention will now be described more fully with reference to the accompanying drawings. Several embodiments of the invention are presented in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1, a channel searching method in a first embodiment of the present invention is shown, which can be applied to an intelligent television, and the channel searching method includes steps S01 to S03.
In step S01, when a channel searching command is detected, a search frequency band is obtained.
The channel searching instruction can be input by a user through modes of remote control, key pressing, touch control, induction and the like, and can also be generated by the intelligent television. The search frequency band can be a frequency region or a frequency point set, and the frequency points can be preset before the smart television leaves a factory and in the later use process.
Step S02, determining whether there is a target frequency point associated with program information in the search frequency band.
When it is determined that the target frequency point associated with the program information exists in the search frequency band, step S03 is executed, and when it is determined that the target frequency point associated with the program information does not exist in the search frequency band, step S04 is executed.
It should be noted that, because the automatic channel searching acquires program information (such as an electronic program guide) in a corresponding frequency point and stores the acquired program information, the program information is the associated program information of the frequency point.
On the basis, when the target frequency point associated with the program information is judged to exist in the search frequency band, the target frequency point represents that the intelligent television has already performed a channel searching action before, and only the effective frequency point can be associated with the program information, so that the target frequency point is the effective frequency point in the search frequency band; when it is determined that the target frequency point associated with the program information does not exist in the search frequency band, the situation represents that the channel search operation of the smart television has not been performed before, and the situation generally occurs in the process of performing the channel search after the smart television is started for the first time.
Step S03, performing channel search on each target frequency point to update program information associated with each target frequency point.
It can be understood that after the effective frequency points are acquired, in order to save the channel searching time, the channel searching action can be performed only for the effective frequency points (namely, the target frequency points), and in addition, when a certain frequency point is subjected to channel searching again, the currently acquired program information will replace the originally recorded program information.
It should be noted that, since the programs of the tv station (corresponding to a certain frequency point) will change, the programs will be frequently added or deleted, but if the user does not switch to the frequency point, the user generally does not know that there is such an update, and if it takes more time to perform an automatic channel search all the time, only one update is performed on the frequency point where the program is currently available, and the time for the automatic channel search will be reduced.
And step S04, searching each frequency point of the search frequency band.
It can be understood that since the smart television has not performed the channel searching operation before, it is currently only able to perform a full-flat channel searching.
Based on the channel searching method in the embodiment, because the channel searching time is short, a user can input a channel searching instruction to the intelligent television every time the user starts the intelligent television, so that the program information of all effective frequency points in the intelligent television is updated, and the program change is prevented from being missed.
In summary, in the channel searching method in the above embodiment of the present invention, when entering an automatic channel searching, it is automatically determined whether target frequency points associated with program information exist in a search frequency band, and since only valid frequency points are associated with the program information, once it is determined that the target frequency points exist, the target frequency points are represented as valid frequency points, and channel searching is performed on each target frequency point to update the program information associated with each target frequency point.
Referring to fig. 2, a channel searching method according to a second embodiment of the present invention is shown, which can be applied to an intelligent television and includes steps S11 to S19.
Step S11, when a channel searching command is detected, determining whether there is a pre-stored command in the mapping table that is consistent with the channel searching command.
When it is determined that there is a pre-stored command in the mapping table that is consistent with the channel searching command, step S12 is executed, and when it is determined that there is no pre-stored command in the mapping table that is consistent with the channel searching command, it represents that the channel searching command is in error, and does not proceed downward and an error prompt may be returned.
Step S12, obtaining a preset frequency band corresponding to the pre-stored instruction in the mapping table as a search frequency band.
It can be understood that there is a difference between the tv frequency bands corresponding to each region (for example, differences between uk and china), and these tv frequency bands are known and generally do not change, so in specific implementation, a corresponding unique channel searching instruction can be written for the tv frequency bands of each region, and these tv frequency bands and corresponding channel searching instructions are prestored in the mapping table, and the mapping table is stored in the storage of the smart tv.
For example, when a user in china clicks a channel search by using a remote controller, after receiving a channel search command, the smart television automatically generates a channel search instruction corresponding to china, acquires a television frequency band corresponding to the channel search instruction from the mapping table, and performs a channel search operation.
In addition, in other embodiments, the smart television can also locate the region through a GPS and automatically generate the television frequency band of the region.
Step S13, determining whether there is a target frequency point associated with program information in the search frequency band.
When it is determined that the target frequency point associated with the program information does not exist in the search frequency band, step S14 is executed, and when it is determined that the target frequency point associated with the program information exists in the search frequency band, steps S15 to S16 are executed.
And step S14, searching each frequency point of the search frequency band.
In step S15, a query message is issued to query the user whether to perform a full channel search.
The sending mode of the inquiry information can be pop-up frame display, language broadcasting and the like, and when the inquiry information appears, a user can input own selection in modes of remote control, key pressing, touch control, induction and the like.
It should be noted that the purpose of setting the inquiry mechanism is to facilitate the user to select autonomously, and avoid that after the system determines that there is a target frequency point in the channel searching frequency band, the system can only perform channel searching operation on the currently known effective frequency point, and some areas may increase or decrease the effective frequency point, if only the television can perform channel searching on the known effective frequency point, the increased effective frequency point of the television station will be missed, and this embodiment sets the inquiry mechanism to better solve the problem.
And step S16, determining whether a selection instruction input by the user for the inquiry information is monitored within a preset time.
The mode of the user inputting the selection instruction comprises any one of remote control input, key clicking, touch input and induction input.
When it is determined that the selection command input by the user for the query information is not monitored within the preset time, the steps S17 to S18 are performed, and when it is determined that the selection command input by the user for the query information is not monitored within the preset time, the step S19 is performed.
It should be noted that the time-limit mechanism is set to avoid the phenomenon that the smart television waits for the user to confirm all the time, and improve the user experience.
And step S17, judging whether the user selects to execute the full frequency channel searching according to the selection instruction.
It can be understood that, when the user inputs a selection instruction (yes or no) within the preset time, the channel searching mode is selected according to the selection instruction, and if the selection instruction is not input within the preset time, the channel searching mode is selected according to the priority of the channel searching mode.
When it is determined according to the selection instruction that the user selects to perform the full-frequency channel searching, the step S14 is executed, that is, the full-frequency channel searching is executed, and when it is determined according to the selection instruction that the user selects not to perform the full-frequency channel searching, the step S18 is executed, that is, the frequency channel searching is executed.
Step S18, performing channel search on each target frequency point to update program information associated with each target frequency point.
And step S19, selecting a channel searching mode with the highest priority for channel searching, wherein the channel searching mode comprises full frequency point channel searching and channel searching for each target frequency point.
In a specific implementation, before the step of selecting the channel searching mode according to the priority of the channel searching mode, the method may further include:
traversing the selection instruction input by the user aiming at each inquiry information, and taking the channel searching mode with the most selection times as the channel searching mode with the highest priority.
Based on this, the present embodiment automatically takes the channel searching method with the largest number of selections as the channel searching method with the highest priority. However, it is understood that in addition to this, in other embodiments, the priority of the channel searching mode may be preset according to different preferences of the user, or the smart tv may automatically generate the priority according to other modes.
For example, when the selection instruction input by the user for the query information sent by the smart television each time is that full-frequency-point channel searching is not selected, the system takes the channel searching mode of "searching for each target frequency point" as the channel searching mode with the highest priority, and then full-frequency-point channel searching is performed.
In summary, compared with the channel searching method in the first embodiment, the channel searching method in the above embodiments of the present invention sets the query mechanism and the time-limited mechanism, so that the whole channel searching method is more reasonable, and the stability of the system and the experience of the user are improved.
Referring to fig. 3, a channel searching method according to a third embodiment of the present invention is shown, which includes steps S21 through S27.
In step S21, when a channel searching command is detected, a search frequency band is obtained.
Step S22, determining whether there is a target frequency point associated with program information in the search frequency band.
When it is determined that the target frequency point associated with the program information exists in the search frequency band, step S23 is executed, and when it is determined that the target frequency point associated with the program information does not exist in the search frequency band, step S24 is executed.
Step S23, performing channel search on each target frequency point to update program information associated with each target frequency point.
And step S24, searching each frequency point of the search frequency band.
In step S25, when the current channel searching operation is completed, the time of the current channel searching is recorded and timing is started.
And the starting time of the timing is the time for completing the current channel searching.
In step S26, when a power-on signal is detected, it is determined whether the timing reaches a predetermined time (e.g., one month).
It can be understood that, each time the smart television is turned on, the system determines whether the current timing reaches the predetermined time, and if the timing reaches the predetermined time, the system represents that the time for searching the channels again is reached, then step S27 is executed, otherwise, the system does not operate to continue monitoring.
And step S27, automatically generating the channel searching instruction.
It can be understood that, after the channel searching instruction is automatically generated, the system acquires a channel searching instruction again, and automatically completes the channel searching action by the channel searching method.
In summary, compared with the channel searching method in the first embodiment, the channel searching method in the above embodiments of the present invention sets the automatic channel searching mechanism, so that the system automatically searches channels at intervals to avoid missing program updates, thereby further improving user experience.
