It is to be understood that specific embodiment described herein is only in order to explain the present invention, it is not intended to limit the present invention.
As shown in Figure 1, the present invention's a kind of intelligence equipment starting method first embodiment is shown. The intelligent equipment starting method of this embodiment comprises:
Step S10, unlatching intelligence equipment;
Step S20, whether it is exchange power-off when judging that described intelligence equipment shut down last time; If then performing step S30, if not, then step S40 is performed;
Step S30, execution cold start-up, to carry out program broadcasting;
Step S40, according to described intelligence equipment environment of system variable, judge described intelligence equipment whether support internal storage starting; If then performing step S50, if not, then above-mentioned steps S30 is performed;
Step S50, execution internal storage starting, to carry out program broadcasting.
In the present embodiment, the type of intelligence equipment can be arranged according to actual needs, below will be described in detail for intelligent television. The present embodiment is the intelligent television hardware platform supporting that STR starts and the intelligent television hardware platform not supporting STR to start, each provide STR startup and these two different Booting sequence of cold start-up, by whether intelligent television shutdown last time is that exchange power-off and environment of system variable select execution STR startup still to perform cold start-up.
Specifically, after intelligent television is opened, central processing unit (CentralProcessingUnit, CPU) powers on, and runs Boot loader (boot&loader). First boot&loader program judges that intelligent television shutdown last time is exchange power-off shutdown or control button shutdown, this control button can be the shutdown button above telepilot, can also be the shutdown button being arranged at intelligent television side, or user is by body sense instruction simulation shutdown button. If shutdown intelligent television last time is exchange power-off shutdown, this show intelligent television before shutdown last time, in DDR internal memory, do not preserve shutdown last time before CPU running state information, namely DDR internal memory also falls electricity, without any preservation information, therefore, intelligent television performs cold start-up, to carry out program broadcasting. If intelligent television last time, shutdown was not ac dump, but remote-control closedown or the shutdown of other software timings, then environment of system variable according to intelligent television judges whether intelligent television supports that STR starts. It should be appreciated that judge whether intelligent television is supported that STR starts and also can preservation state amount be judged by other. Such as, can arrange when the environment of system variable str_enable of intelligent television is true, support that STR starts; When environment of system variable str_enable is false, do not support that STR starts. When intelligent television does not support that STR starts, perform cold start-up, to carry out program broadcasting, when intelligent television supports that STR starts, perform STR and start, to carry out program broadcasting.
The embodiment of the present invention, when intelligent television is opened, if being exchange power-off when intelligent television shut down last time, then performs cold start-up, to carry out program broadcasting; If not exchange power-off, then environment of system variable according to intelligent television judges whether intelligent television supports that STR starts. If supporting, STR starts, then perform STR and start, to carry out program broadcasting; If not supporting, STR starts, then perform cold start-up, to carry out program broadcasting. Make by detecting whether intelligence equipment supports that STR startup is selected to perform STR and started or cold start-up, solve and perform intelligent television software that STR starts do not supporting on the hardware platform of STR can operation exception, it is desired to the system that STR starts with do not support that the system that STR starts needs the problem carrying out separate management and maintenance. Support that STR starts and do not support the system software that STR starts by compatibility design, can allow the running software supporting STR to start on the hardware platform not supporting STR to start, can also allow the running software not supporting STR to start on the hardware platform supporting STR, thus improve the handiness of intelligent television system exploitation, reduce system development maintenance cost.
Further, as shown in Figure 2, based on above-mentioned first embodiment, it is proposed that control method the 2nd embodiment of the present invention's intelligence equipment, in this embodiment, above-mentioned steps S50 can comprise:
Step S51, in the process performing internal storage starting, the current running status of described intelligence equipment central processing unit is reduced to the running status of central processing unit preserved before shutting down last time;
Step S52, judge described first source signal and whether complete locking, and whether described 2nd information source completes synchronously; If then performing step S53, if not, then step S54 is performed;
Step S53, according to program play parameter carry out program broadcasting;
The time is preset in step S54, time delay, until described first source signal completes locking, and described 2nd information source complete synchronous after, play parameter according to program and carry out program broadcasting.
In the present embodiment, if shutdown last time of above-mentioned intelligent television is not exchange power-off shutdown, and intelligent television supports that STR starts, then intelligent television performs STR and starts. Before shutting down last time, in DDR internal memory, save CPU running state information before shutting down last time due to intelligent television, therefore when intelligent television performs STR startup, CPU also origin operation can be performed. From DDR internal memory, obtain the CPU running state information before shutting down last time, the current running status of intelligent television CPU is reduced to the running status of the CPU preserved before shutting down last time.
After intelligent television heavily opens reduction, owing to the master control chip (SOC) of intelligent television, demod/tuner, power amplifier etc. all experienced by power process, so the signals such as Audio and Video can not be played out at once. Needing whether the first source signal judging intelligent television completes locking, and whether the 2nd information source completes synchronously, this first information source letter comprises the information sources such as AV, VGA, Ypbpr, HDMI, and the 2nd information source comprises the information sources such as DTV, ATV. Namely the information sources such as AV, VGA, Ypbpr, HDMI are needed to carry out semaphore lock detection, for information sources such as DTV, ATV, it is necessary to carry out audio-visual synchronization detection.
When the first source signal completes locking, and the 2nd information source complete synchronous after, when intelligent television receives corresponding semaphore lock notice and audio-visual synchronization notice, playing parameter according to program and carry out program broadcasting, this program plays parameter can comprise video display parameters, window display size, sound playing parameters etc. When the first source signal does not complete locking and/or the 2nd information source does not complete synchronously, intelligent television does not receive corresponding semaphore lock notice and/or audio-visual synchronization notice, and with regard to the time delay default time, this default time can be arranged flexibly according to particular case. Time delay waits until the first source signal completes locking, and the 2nd information source complete synchronous after, intelligent television have received corresponding semaphore lock notice and audio-visual synchronization notice, just according to the different video display parameters of the formatting of signal, window display size, sound playing parameters etc., and video is shown to intelligent television display screen, sound is played back from audio amplifier.
The present embodiment intelligent television carry out STR start time, current for CPU running status is reduced to the CPU running status before shutting down last time, and the first source signal complete locking and the 2nd information source complete synchronous after, carry out program broadcasting. Achieve and select STR to start according to actual needs, it is to increase the handiness of intelligent television system exploitation and reduce maintenance cost.
Further, as shown in Figure 3, based on above-mentioned first embodiment, it is proposed that control method the 3rd embodiment of the present invention's intelligence equipment, in this embodiment, above-mentioned steps S30 can comprise:
Step S31, in the process performing cold start-up, the intelligence kernel of equipment described in initialize and respectively driving, detects whether described intelligence equipment supports internal storage starting, and arranges the environment of system variable of described intelligence equipment according to detected result;
Each function module of intelligence equipment described in step S32, initialize, switches to the information source before shutting down last time by the information source of described intelligence equipment, and described information source comprises the first information source and the 2nd information source;
Step S33, judge described first source signal and whether complete locking, and whether described 2nd information source completes synchronously; If then performing step S34, if not, then step S35 is performed;
Step S34, according to program play parameter carry out program broadcasting;
The time is preset in step S35, time delay, until described first source signal completes locking, and described 2nd information source complete synchronous after, play parameter according to program and carry out program broadcasting.
In the present embodiment, if shutdown last time of above-mentioned intelligent television is exchange power-off shutdown, or intelligent television does not support that STR starts, then intelligent television performs cold start-up. Before shutting down last time, in DDR internal memory, CPU running state information before shutting down last time is not preserved, therefore when intelligent television performs cold start-up, it is necessary to perform initialize operation due to intelligent television.
First, after each driving of kernel and SOC inside of initialize intelligent television, kernel and driving initialize, kernel program is at running background, and intelligent television system starts to run the program of User space. First User space program can be loaded into the configuration file of intelligent television, after configuration file is loaded into, intelligent television will detect whether it supports internal storage starting (each cold start-up flow process of intelligent television all can detect a time), and the environment of system variable of intelligence equipment is set according to detected result, following examples will be described in detail.
The User space program that intelligent television runs is except whether detection supports STR startup, still carry out initialize to independent of other chips outside SOC, i.e. each function module of initialize intelligence equipment, Functional Module draws together the basic module such as video, audio, CI+, cec, database, graphic figure, ratio mode zoom, power amplifier, demod, tuner, cable network, wifi, bluetooth, video, sound, and the initialize of these modules is the necessary basis that intelligent television carries out normal local information source audio and video playing, network audio-video is play.
After above-mentioned each function module initialize completes, the information source before intelligent television switching information source to shutdown last time, information source switches which information source control intelligent television is operated in. Information source comprises first information source such as AV, VGA, HDMI1, Ypbpr, and the 2nd information source such as DTV, ATV. For the first information source, after information source has switched, do not need other playback action, just can wait the driving layer notice judging whether signal locks in next step, for the 2nd information source, except being done information source and switching, also to be performed the action that program is play, the concrete program playing which channel, after playback action is finished, waits the notice whether audio frequency and video are synchronous.
Intelligent television when carrying out cold start-up, owing to the SOC of intelligent television, demod/tuner, power amplifier etc. all experienced by power process, so the signals such as Audio and Video can not be played out at once. Need whether the first source signal judging intelligent television completes locking, and whether the 2nd information source completes synchronously. When the first source signal completes locking, and the 2nd information source complete synchronous after, when intelligent television receives corresponding semaphore lock notice and audio-visual synchronization notice, the program different according to the formatting according to signal is play parameter and is carried out program broadcasting, and this program plays parameter can comprise video display parameters, window display size, sound playing parameters etc. When the first source signal does not complete locking and/or the 2nd information source does not complete synchronously, intelligent television does not receive corresponding semaphore lock notice and/or audio-visual synchronization notice, and with regard to the time delay default time, this default time can be arranged flexibly according to particular case. Time delay waits until the first source signal completes locking, and the 2nd information source complete synchronous after, intelligent television have received corresponding semaphore lock notice and audio-visual synchronization notice, just according to the different video display parameters of the formatting of signal, window display size, sound playing parameters etc., and video is shown to intelligent television display screen, sound is played back from audio amplifier.
The present embodiment, when intelligent television carries out cold start-up, to the kernel of intelligent television, each drives and each function module carries out initialize, and the first source signal complete locking and the 2nd information source complete synchronous after, carry out program broadcasting. Achieve and select cold start-up according to actual needs, it is to increase the handiness of intelligent television system exploitation and reduce maintenance cost.
Further, based on above-mentioned 3rd embodiment, it is proposed that control method the 4th embodiment of the present invention's intelligence equipment, in this embodiment, above-mentioned steps S31 can comprise:
Obtain corresponding configuration file according to item number, judge whether described configuration file exists the enable configuration item of the internal memory specified;
If there is the enable configuration item of internal memory specified, then parameter according to described internal memory enable configuration item judges whether described intelligent equipment supports internal storage starting;
If support internal storage starting, then by described environment of system variable set up for supporting internal storage starting;
If not supporting internal storage starting, then according to the magnitude of voltage of universal input/output pin of described intelligence equipment master control chip, judge whether described intelligence equipment supports internal storage starting;
If support internal storage starting, then by described environment of system variable set up for supporting internal storage starting;
If not supporting internal storage starting, then by described environment of system variable set up for not support internal storage starting.
In the present embodiment, intelligent television will according to the voltage condition of the facilities of configuration file and the universal input/output pin (GPIO pin) of SOC, and arranging environment of system variable str_enable is for true or for false. According to whether detection intelligent television supports that the detected result that STR starts arranges the environment of system variable of intelligent television, carry out in intelligent television cold start-up initialize process. In intelligent television cold start-up process, after kernel and basic driver initialize run, whether intelligent television just supports, after reading product configuration file, the detection that STR starts, and after having detected, result is write in environment of system variable str_enable. Specifically, intelligent television, first according to item number, gets corresponding modelini configuration file, judges whether there is the enable configuration item of the internal memory specified in this configuration file (STRenable configures option cfg_str_enable). If there is the enable configuration item of internal memory specified, just parameter according to the enable configuration item of internal memory judges whether intelligent television supports that STR starts. If supporting, STR starts, then by environment of system variable set up for supporting that STR starts. Such as, whether the value (cfg_str_enable) judging the enable configuration option of this internal memory is true, if the value of the enable configuration option of internal memory is true, just the environment of system variable str_enable of this intelligent television is set to true, represents that intelligent television supports that STR starts.
If not supporting, STR starts, then according to the magnitude of voltage of the universal input/output pin (GPIO pin) of intelligent television SOC, judge whether intelligent television supports that STR starts. Such as, if there is the enable configuration item of internal memory specified, but the value of the enable configuration item of the internal memory specified is false, the magnitude of voltage of the enable relevant GPIO pin of internal memory specified in advance with regard to further judgement (assumes that system represents that hardware does not support that STR starts when to have defined the magnitude of voltage of GPIO pin be high level, represent that hardware supported STR starts when this magnitude of voltage is lower level). If the magnitude of voltage of this GPIO pin is lower level, the environment of system variable str_enable just arranging this intelligent television is true, represent that intelligent television supports that STR starts, if the magnitude of voltage of this GPIO pin is high level, the environment variable str_enable just arranging this TV is false, represent that intelligent television does not support that STR starts, thus whether intelligent television supports that the detection that STR starts completes.
It should be noted that, said system environment variable or other can preservation state amount, it is comprehensively arrange in conjunction with the value of the enable configuration item of internal memory and GPIO pin voltage height simultaneously, the program first judges the value of the enable configuration item of internal memory, the magnitude of voltage of rear judgement GPIO pin, as long as STR starts to have one to support in both, just by the environment of system variable set up of intelligent television for supporting that STR starts, intelligent television system just can perform STR Booting sequence. , it is also possible to be only arrange by judging the result of the enable configuration item of internal memory in advance, certainly or only prejudge and specify the result of GPIO pin voltage height to arrange. Environment of system variable can be arranged flexibly according to particular case, does not limit the present invention.
Further, if there is not the enable configuration item of the internal memory specified, then according to the magnitude of voltage of universal input/output pin of described intelligence equipment master control chip, judge whether described intelligence equipment supports internal storage starting; If support internal storage starting, then by described environment of system variable set up for supporting internal storage starting; If not supporting internal storage starting, then by described environment of system variable set up for not support internal storage starting.
Specifically, if above-mentioned judgement configuration file does not exist the enable configuration item of the internal memory specified, then according to the magnitude of voltage of intelligent television SOC GPIO pin, judge whether intelligent television supports that STR starts. Such as, judge the magnitude of voltage (assuming that system represents that hardware does not support that STR starts when to have defined the magnitude of voltage of GPIO pin be high level, represent that hardware supported STR starts when this magnitude of voltage is lower level) of the enable relevant GPIO pin of internal memory specified in advance. If the magnitude of voltage of this GPIO pin is lower level, the environment of system variable str_enable just arranging this intelligent television is true, represent that intelligent television supports that STR starts, if the magnitude of voltage of this GPIO pin is high level, the environment variable str_enable just arranging this TV is false, represents that intelligent television does not support that STR starts.
The present embodiment intelligent television can according to the voltage condition of the facilities of the enable configuration item of the internal memory specified in configuration file and SOC GPIO pin, environment of system variable is set, to distinguish whether intelligent television supports that STR starts, so that intelligent television selects STR to start or cold start-up, it is to increase the handiness of intelligent television system exploitation and reduce maintenance cost.
Accordingly, as shown in Figure 4, it is proposed to the present invention's a kind of intelligence device start device first embodiment. The intelligent device start device of this embodiment comprises:
Whether shutdown judges module 100, for opening intelligence equipment, be exchange power-off when judging that described intelligence equipment shut down last time;
Processing module 200, if for exchange power-off, then performing cold start-up, to carry out program broadcasting; If not exchange power-off, then according to the environment of system variable of described intelligence equipment, judge whether described intelligence equipment supports internal storage starting;
Execution module 300, if for supporting internal storage starting, then performing internal storage starting, to carry out program broadcasting; If not supporting internal storage starting, then perform cold start-up, to carry out program broadcasting.
In the present embodiment, the type of intelligence equipment can be arranged according to actual needs, below will be described in detail for intelligent television. The present embodiment is the intelligent television hardware platform supporting that STR starts and the intelligent television hardware platform not supporting STR to start, each provide STR startup and these two different Booting sequence of cold start-up, by whether intelligent television shutdown last time is that exchange power-off and environment of system variable select execution STR startup still to perform cold start-up.
Specifically, after intelligent television is opened, central processing unit (CentralProcessingUnit, CPU) powers on, and runs Boot loader (boot&loader).
