Detailed Description
The embodiment of the invention provides a method and a device for controlling communication messages of an intelligent television in a standby state, which are used for solving the technical problem that the user experience is reduced because the communication messages cannot be reasonably controlled in the standby state of the intelligent television in the prior art.
In order to solve the technical problems, the general idea of the embodiment of the present application is as follows:
the method for controlling the communication message of the intelligent television in the standby state comprises the following steps: when the starting time of the timing task in the intelligent television is reached, the intelligent television is switched from a true standby state to a false start state and starts the timing task; in a false power-on state, sending a first communication message to external equipment interconnected and intercommunicated with the intelligent television; the first communication message is used for enabling the smart television and the external equipment to keep interconnection and intercommunication, but not enabling the external equipment to power amplifier; when the timing task is finished, if other timing tasks which are being executed exist in the intelligent television, the false starting state is switched to a false standby state; in the false standby state, forbidding sending a second communication message to the external equipment; and the second communication message is used for controlling the standby of the external equipment.

In order to better understand the technical solutions of the present invention, the following detailed descriptions of the technical solutions of the present invention are provided with the accompanying drawings and the specific embodiments, and it should be understood that the specific features in the embodiments and the examples of the present invention are the detailed descriptions of the technical solutions of the present invention, and are not limitations of the technical solutions of the present invention, and the technical features in the embodiments and the examples of the present invention may be combined with each other without conflict.
Referring to fig. 1, an embodiment of the invention provides a method for controlling a communication message in a standby state of an intelligent television, and the processing procedure of the method is as follows.
Step 101: and when the starting time of the timing task in the intelligent television is reached, the intelligent television is switched from the true standby state to the false on state and starts the timing task.
And in the true standby state, all tasks in the intelligent television are closed, and only the MCU of the intelligent television is in the running state. The false power-on state is a state in which the smart television is powered on but does not execute a play task.
In order to distinguish various task states of the smart television, the task states can be distinguished by setting a state table for the smart television, and specifically, see table 1.
TABLE 1
It should be understood that the task states listed in table 1 are only a part of the task states of the smart television, and different task states may be designed according to different systems adopted by the smart television, so that the specific task states possessed by the smart television are not limited herein.
By the mode shown in table 1, different task states can be set for different services of the smart television. In practical applications, corresponding operations may be performed according to the ID or the state value of the task state.
The timing task can be a reserved recording task set in the smart television by a user, a timing updating task of the smart television and the like. In the following embodiments, a description will be given taking a scheduled recording task as an example.
For example, the timing task may be: morning news is recorded at 9:00, financial news is recorded at 11:00, or system updates are made at 00:00, etc. The timing tasks are stored in the timing task information of the intelligent television.
Generally, when the smart tv executes a timing task, the smart tv may play a tv program or may not play the tv program.
Taking the scheduled recording task as an example, when a user uses the scheduled recording task of the smart television to make a reservation, the user usually writes the reserved program information into the scheduled task information (which may also be referred to as reserved task information), so that the smart television automatically records the program according to the program information in the scheduled task information.
After a user sets a program to be reserved and recorded through a remote controller, the smart television synchronizes the timing task to the timing task information, the timing task information is used for storing all reserved timing tasks, and the storage form of the timing task information can be in the form of a data table, a database and the like, and is not limited specifically.
When the user selects to enable the smart television to be in a standby state through a standby key on the remote controller, the smart television judges whether a timing task is currently executed, such as 9:00 recording morning news, 00:00 perform update tasks, etc. If yes, enabling the intelligent television to be in a false standby state, and enabling the intelligent television to be in a true standby state after the task being executed is completed; and if not, allowing the intelligent television to be in true standby. At this time, the intelligent television sends a standby command to the external equipment such as the sound equipment which is interconnected with the intelligent television, so that the external equipment is in standby.
After the intelligent television is in a true standby state and before the timing task is started, the intelligent television can be periodically controlled to be started falsely according to the preset time, and the starting time of the timing task is synchronized into a microcontroller MCU of the intelligent television, so that the starting time in the MCU can be updated regularly, and the timing task can be started when the starting time of the timing task is up.
Before the timing task is started, if the power supply of the intelligent television is powered on again after power failure (sometimes also called power failure), the intelligent television is controlled to be started falsely, the starting time is synchronized into the MCU, so that the timing task can be started when the starting time is up, and the timing task cannot be executed in time after the starting time is up due to the fact that the information in the MCU is lost after the power failure of the intelligent television.
When the computer is booted, whether an Electronic Program Guide (EPG) is updated or not can be detected, and if the EPG is updated, the update information is synchronized into the timing task information. And recalculates the start time of the timed task after the update is completed.
For example, assuming that the smart television is in a true standby state, the smart television is automatically and falsely started every 2 hours, and enters a false start state, when the timing time of the timer of the smart television reaches the preset judgment time of 2 hours, the smart television is controlled to falsely start, whether the EPG is updated or not can be checked during false start, and if so, the update information is synchronized into the timing task information. And recalculates the start time of the timed task after the update is completed.
For another example, suppose the smart tv is in the true standby mode, a power failure occurs suddenly at home of the 3:00 user, and after 10 minutes, a call is received again, and the playing time of the football program which is recorded at the beginning of 3:30 reserved by the user in the period is changed to 4: 00. After the smart television is powered on, entering a false start mode, simultaneously checking whether the EPG is updated, and when the EPG is updated (for example, the broadcasting time of the football program is updated to 4:00), correspondingly updating the recording start time of the football program in the timing task information based on the updated electronic program guide, that is, adjusting the recording start time of the football program from 3:30 to 4: 00. And recalculating the timing time, namely calculating the time difference between the minimum starting time 4:00 and the current time 3:10 to be 50 minutes, namely the timing time is 50 minutes, and counting down to 0 when the timing time is up to 0, namely the timing time is
Further, the process of starting the timing task is as follows:
firstly, calculating the difference between the effective minimum starting time and the current time in the timing task information to obtain the timing time; wherein the effective minimum start-up time is the minimum start-up time after the current time.
For example, there are 3 timed tasks in the timed task information, the corresponding start time is 3:00, 9:00, 13:00 once, and the current time is 3:30, since power is suddenly cut off at 2:50 and power is turned on at 3:15, after power is turned on again, the timed task with the start time of 3:00 is still in the timed task information, but the timed task of 3:00 is out of date for the current time of 3:30, and the task should be deleted, so the minimum start time valid in the timed task information should be the minimum start time after the current time, that is, 9: 00.
For deleting the timing task which is expired in the timing task information, the following method can be adopted:
by comparing the size of each starting time in the timed task information with the current time, if the starting time is before the current time, the corresponding timed task is indicated to be expired and should be deleted from the timed task information, and if the starting time is after the current time, the corresponding timed task is indicated to be valid and should be reserved.
Then, the timing time is counted down, and when the count-down reaches zero, the timing task is started.
For example, assume that the current time is 2:30, and there are 5 programs to be recorded in the reserved task information, i.e., program 1-program 5, see table 2.
TABLE 2
| ID | Program title | Starting time | End time |
| 1 | Program 1 | 3:30 | 4:00 |
| 2 | Program 2 | 4:20 | 5:20 |
| 3 | Program 3 | 2:35 | 3:20 |
| 4 | Program 4 | 5:30 | 6:30 |
| 5 | Program 5 | 1:30 | 2:20 |
First, a valid minimum start time is determined based on the timed task information and the start times of the 5 timed tasks (i.e., programs to be recorded) in the current time (i.e., from table 2).
For example, each timed task in the timed task information may be compared with the current time 2:30, and the timed task corresponding to the starting time before 2:30, that is, the program 5, may be deleted; the remaining timed tasks (i.e., programs 1-4) are then ranked, with the results of the ranking being: the start time of program 3 < start time of program 1 < start time of program 2 < start time of program 4, so that it can be determined that the minimum start time effective in the reservation task information is the start time 2:35 of program 3.
Then, the effective minimum start time 2 in the timing task information is calculated: the time difference between 35 and the current time 2:30 is 5 minutes, resulting in a timed time of 5 minutes.
And finally, counting down the timing time of 5 minutes, and starting recording the timing task program 3 when the counting down reaches 0.
After the smart tv switches from the true standby state to the false on state and starts the timing task, step 102 is executed.
102, sending a first communication message to an external device interconnected and communicated with the intelligent television in a false power-on state; the first communication message is used for enabling the smart television and the external equipment to keep interconnection and intercommunication, but not enabling the external equipment to power amplifier.
It should be understood that in the present application, both the smart tv and the external device support the consumer electronics control CEC and the sound backhaul ARC.
When the intelligent television is in the false power-on state, the intelligent television and the external equipment carry out basic communication by sending the first communication message to the external equipment connected with the intelligent television without waking up the external equipment. For example, online notifications are made at intervals. Therefore, the intelligent television can not wake up the external equipment when executing the timing task in the false on state, and further the external equipment can not generate sound and influence user experience.
If the smart television starts a timing task in a real startup state, the smart television sends a wakeup instruction to the external device, such as CEC _ OC _ SYSTEM _ AUDIO _ MODE _ REQUEST, so that the external device can be awakened.
For example, the following message contents may be employed:
Message.dest＝CEC_ADDRESS_AUDIO
Message.Datablock[0]＝CEC_OC_SYSTEM_AUDIO_MODE_REQUEST
Message.Datalength＝3
the address message of the external device is generally 5, the message command message datablock [0] is generally fixed to 0X70, and the external device can be awakened from the standby state according to the protocol requirement after receiving the message.
Referring to fig. 2, the state synchronization process between the smart tv and the external device is as follows.
Step 201: when the intelligent television is started, whether the intelligent television is really started or not is judged.
If so, step 2011 is executed.
Step 2011: and sending a third communication message to the external equipment to wake up the external equipment.
If not, go to step 203.
Step 202: and when the intelligent television is in a standby state, judging whether the intelligent television is in a true standby state.
If so, go to step 2021.
Step 2021: and sending a second communication message to the external equipment so as to enable the external equipment to enter a standby state.
If not, go to step 203.
Step 203: the intelligent television sends a first communication message to the external equipment so as to keep interconnection and intercommunication with the external equipment, and at the moment, the external equipment keeps a standby state.
By the method, the external equipment can be in a standby state when the intelligent television executes the timing task and does not need to sound; and when the sound is required to be sounded, waking up the external equipment.
At the end of the timed task, please refer to steps 103-104.
And 103, when the timing task is finished, if other timing tasks which are being executed exist in the intelligent television, switching the false on-state to a false standby state.
104, prohibiting sending a second communication message to the external equipment in a false standby state; and the second communication message is used for controlling the standby of the external equipment.
Specifically, the second communication message may be CEC _ OC _ STANDBY.
Through letting intelligent television under the false standby state, forbid the mode of sending second communication message to external equipment, can further let external equipment when intelligent television carries out the task state switching, not make sound, and then reasonable control communication message, effectual promotion user experience.
When the timing task is finished, if no other task is executed in the intelligent television, the false power-on state is switched to a true standby state, and a second communication message is sent to the external equipment, so that the external equipment is in a standby state.
For example, in the false STANDBY state, the smart tv sends a second communication message CEC _ OC _ STANDBY message to the external device. For example, the following message contents may be sent:
Message.src＝CEC_ADDRESS_TV
Message.dest＝CEC_ADDRESS_AUDIO
Message.Datablock[0]＝CEC_OC_STANDBY
Message.Datalength＝3
the CEC _ ADDRESS _ TV is an ADDRESS of the smart TV, the CEC _ ADDRESS _ AUDIO is an ADDRESS of the external device, and is generally 5, and the CEC _ OC _ STANDBY is a message command, and is generally 0X 36.
After receiving the message, the external device switches the external device from the power-on state to the standby state.
It should be understood that the above-mentioned scheme provided by the present invention can be used not only for recording television programs, but also for recovering other timing tasks in the smart television. Such as a timed startup task, a timed update task, etc.
In order to enable those skilled in the art to fully understand the present solution, a specific example is provided below for illustration.
Suppose that a user is watching a healthy program through an intelligent television at present and reserves 4 programs in a table 3 to record the program at respective starting time, and the intelligent television plays program sound effects through an external device connected with the intelligent television, such as an Amplifier. The preset time of the smart television is 2 hours, namely the smart television is automatically started up in a false mode every 2 hours.

After a user watches a healthy program 19:10, through a first operation, in order to enable the smart television to enter a standby state, whether the smart television has a timing task currently being executed or not needs to be judged at the moment, if so, the news program is recorded, and at the moment, the smart television enters a false standby mode, and sends a second communication message to an Ampere bridge power amplifier of external equipment connected with the smart television, so that the Ampere bridge power amplifier is in a standby state; and after the 19:30 news program is recorded, controlling the intelligent television to enter a true standby state.
After the intelligent television enters the true standby state, periodically entering a false start state according to a preset time of 2 hours, for example, at 21:30, when the preset time is reached for the first time, controlling the intelligent television to false start, and sending a first communication message to the external equipment, so that the intelligent television keeps interconnection and intercommunication with the external equipment, but does not make the external equipment power amplify. And the smart television determines that the effective minimum starting time in the timed task information is 1:30 (corresponding to the football program) on the second day based on the timed task information (table 3) and the current time 21:30, then calculates that the time difference between the current time 21:30 and the effective minimum starting time in the timed task information is 4 hours from the second day 1:30, namely the obtained timed time is 4 hours, then counts down the timed time 4 hours, and starts the timed task of recording the football program when the count down reaches 0.
However, at 24, the power of the user's home is suddenly cut off, and the power supply is restored at 1:00 in the morning, at this time, the smart television enters a false-on state after false-on, and the smart television sends a first communication message to the external device connected with the smart television, so that the smart television performs basic communication with the external device without waking up the external device. Meanwhile, the intelligent television detects that the television program guide is updated, the updating result is that the playing time of the football program is adjusted to be 2:00-3:30, and the intelligent television correspondingly updates the reserved time of the football program in the timing task information according to the updating result, namely, the starting time of the football program is updated to be 2:00 ending time and is updated to be 3: 30. And recalculating the timing time of the football program, specifically, determining that the effective minimum starting time in the new timing task information is 2:00 (corresponding to the football program) based on the new timing task information (namely, the table 3 after the program 1 is deleted and the playing time of the football program is updated) and the current time 1:00, then calculating the time difference between 2:00 and 1:00 to be 1 hour, thereby obtaining the timing time of 1 hour, counting down the timing time, and starting the timing task of recording the football program when the counting down is 0. Meanwhile, a second communication message is sent to the external equipment, so that the external equipment is kept in a standby state, and the external equipment does not make a sound so as to avoid disturbing a user.
If a method of adding hardware is adopted, that is, a small battery is added to prevent the MCU from being powered off, the hardware cost of the intelligent television is increased, and the corresponding recording task cannot be executed when the scene is met.
For example, there are two timing tasks: the start time for recording program 1 is 5:00 and the end time is 6:00, and the start time for recording program 2 is 8:00 and the end time is 9: 00. If the current time is 0 point, the power is off, at this time, because the time of the MCU exists all the time, but the intelligent television cannot be started even if the power is off at 5:00, and if the power is not on until 7 points, the program 2 can be recorded by adopting the technical scheme provided by the application, and the method for adding hardware cannot ensure that the program 2 can be recorded.
