Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
The term " comprising " and " having " of description and claims of this specification and their any deformation, it is intended that
It is that covering is non-exclusive to include, for example, the device for the process or structure for containing series of steps is not necessarily limited to clearly arrange
It is that those structures or step for going out but may include are not listed clearly or for these processes or the intrinsic other steps of device
Rapid or structure.
First aspect of the embodiment of the present invention provides a kind of player method of startup advertisement sound, as shown in figure 1, methods described
Including：
Step S101, based on television startup instruction, after after kernel kernel process initiations, TV is configured to by sound broadcasting path
The loudspeaker of itself, to carry out sound output to startup advertisement by the loudspeaker；
For being mounted with the TV of Android intelligence system after powering, as a rule, Android start-up course can be divided into two
Individual stage, the first stage is Linux startup, and second stage is only Android startup,
In Linux startup stages, Bootloader can be started, Kernel, Driver etc, run rank in kernel kernel
Section, can be to that will initialize typically in kernel to the power amplifier chips of TV itself;The wherein initialization of power amplifier chips
Mainly preset power amplifier initialization data is written in power amplifier chips., can be by sound after power amplifier initialization is completed
Output equipment is set to the machine loudspeaker, and the path for also playing sound is configured to loudspeaker；
To second stage, in Android system service startup stage, surfaceFlinger services can call bootanimation to take
Business process, can further call the advertisement played file prestored, play startup advertisement.
Due to loudspeaker initialization carry out it is more early, so by loudspeaker can be as early as possible to startup advertisement carry out sound it is defeated
Go out, it is typically not in that startup advertisement does not have sound phenomena in prior art when being not connected to external playback equipment that this, which is also,
Reason.
So that external playback equipment is external ARC power amplifying devices as an example, kernel kernel process initiations are treated in step S101
Also include afterwards：
Step S1011, judges whether HDMI passages have external ARC equipment to insert；
Step S1012, if so, then being completed by with the external ARC equipment of the insertion communicate after initialization, returning is used for
Characterize the playable instruction message of the external ARC equipment.
ARC full name be Audio Return Channel, that is, audio return passage.ARC function is exactly to transmit
Voice signal, is specifically referred in the HDMI for supporting ARC, and audio signal can be passed through HDMI by TV by ARC agreements
Line passes back to external power amplifier or other possess the audio frequency apparatus of HDMI ARC functions up.HDMI is used as a digitized video
The reception standard of audio, can be with simultaneous transmission video and audio.
Specifically, for step S1011, it is described to judge whether HDMI passages have external ARC equipment to insert, including：
Step S10111, if the level for detecting the hot plug pin of the HDMI passages changes, has determined the HDMI passages
It is connected with external equipment；
Step S10112, CEC orders are sent to the external equipment, obtain the type of the external equipment；
Step S10113, judges whether HDMI passages are connected with external ARC equipment based on the type.
Determine whether that ARC equipment is accessed, the condition of judgement is the hotplug of corresponding HDMI channel interfaces（Hot plug
Pin）Whether change, and CEC orders determine ARC equipment can Ping lead to, the two all meets, and is determined with ARC equipment
It is successfully accessed, after the hot plug pin level for detecting HDMI passages changes, it may be determined that be connected with external equipment, now
Can not between determine be the external power amplifiers of ARC, when detect external equipment insertion after, TV can be handed over the equipment equipment
Mutually, corresponding order is sent（Give Device Vendor ID, Give Physical Address, Initiate ARC
Deng）, the purpose of these orders is in order to obtain the type of external equipment, based on the return parameters and external equipment defined
The relation of type, it is determined that being external ARC equipment, so as to complete the initialization to external ARC equipment.
Specifically, after the change of hot plug pin level, it is determined that being connected with external playback equipment, sending CEC first before
Ping orders, see whether ping leads to, if it is possible to which ping leads to, and illustrates to have accessed the equipment for supporting CEC agreements.Then proceed to send
Other CEC orders, so as to get external equipment type, and then are realized to external equipment progress initialization operation.
But external ARC equipment initialization times are by many uncontrollable factors, because television needs and external power amplifier
Equipment carries out CEC communications, and communication can just speak after normally completing.CEC communications in itself can not possibly be absolutely successful, and failure is once
It is accomplished by retransmitting once, and repeating transmission is also required to the time.And some some power amplifier self reasons, television sets to external ARC
Preparation is lost one's life after order, and time-consuming for external ARC equipment time of return.Several reasons result in the time-consuming ratio of ARC equipment initialization above
It is longer.
Come again, so that external playback equipment is external Bluetooth equipment as an example, in step S101, treat kernel kernel process initiations
Also include afterwards：
Step S1013, loading bluetooth driving, triggering starts bluetooth management service process；
Step S1014, determines whether that bluetooth equipment is returned by the bluetooth management service process and is linked to be work(；
Step S1015, if so, then returning to the instruction message playable for characterizing the bluetooth equipment.
After the intelligent television start of Android system, first start loading bluetooth driving first, based on bluetooth driving, can touch
Hair starts BluetoothManagerService, that is, bluetooth management service process, whether judges lower bluetooth driving layer segment
It is ready, once being ready to complete, open the bluetooth of TV.Treat that bluetooth equipment is interacted with TV, that is, perform external indigo plant
The company's of returning process of the bluetooth module of tooth equipment and TV, is linked to be work(if returned, returns to what be can play for characterizing bluetooth equipment
Prompting message.
Likewise, because the bluetooth module of television itself needs to interact initialization with external Bluetooth equipment, and
The bluetooth module of TV needs to wait after android BluetoothManagerService startups, could be carried out after opening bluetooth
The connection of external Bluetooth equipment, so needing the longer time could sounding.
Similarly, also numerous other types of external equipment, not exclusively ARC power amplifiers and bluetooth equipment such as Bluetooth audio device
The problem of this programme background technology runs into occurs, under the Booting sequence framework based on Android system, due to external equipment very
Hardly possible starts earlier than startup advertisement, and the problem of startup advertisement does not have sound all unavoidably occurs.
Step S102, during the loudspeaker play startup advertisement, if receiving for characterizing external playback equipment
After playable instruction message, whether the audio output device for judging terminal configuration during last time shutdown is that the external broadcasting is set
It is standby；
In actual start-up course, the time of the initialization procedure needs of external playback equipment is simultaneously unstable, it is possible to can be early,
May be more late, go to monitor whether external playback equipment is ready in real time so needing to open up a watcher thread, Ye Jijie
Receive after the instruction message playable for characterizing external playback equipment, the instruction message can be external playback equipment such as ARC
The message or external Bluetooth audio device that power amplifying device initialization is completed, which have been returned, even successfully indicates message, that is, determines outer
Playback equipment is connect to have can be used for playing sound.Now need to determine whether the sound output of terminal configuration during last time shutdown
Whether equipment is the external playback equipment.
As a rule, in the setting menu of TV, including the option list for indication TV audio output device, use
Family can be based on actual demand, be selected in option list, if user have selected external ARC equipment and be set as sound broadcasting
Standby, voice data to be played will be output in external ARC equipment and play out by that drive part, and switching on and shutting down process is not
The selection of user can be cancelled, the configuration data can be recorded in the database of TV always.
Step S103, if so, sound then is played into path switches to the external playback equipment from the loudspeaker, to cause
The external playback equipment replaces the loudspeaker to play the startup advertisement.
If it is determined that result be to determine that user have selected external playback equipment as audio output device, that is in order to meet
The sound output demand of user, sound broadcasting path can be switched over, be switched to external playback equipment from loudspeaker so that outer
Connect playback equipment and play startup advertisement instead of loudspeaker.
The embodiment of the present invention, based on television startup instruction, after after kernel kernel process initiations, plays logical by sound first
Road is configured to the loudspeaker of TV itself, therefore, it can carry out sound output to startup advertisement by loudspeaker, plays and start shooting in loudspeaker
During advertisement, if receiving external playback equipment is used to characterize after playable instruction message, when judging last time shutdown
Whether the audio output device of terminal configuration is the external playback equipment, if so, sound then is played into path from the loudspeaker
The external playback equipment is switched to, to cause external playback equipment to replace the loudspeaker to play the startup advertisement, compared to
Prior art, because can just be initialized after kernel processes to the power amplifying device of TV itself, therefore, the loudspeaker of TV can
Go to call startup advertisement with the bootanimation service processes in servicing earlier than Android system so that startup advertisement can be with base
Sound output is carried out in loudspeaker, if in loudspeaker playing process, external playback equipment, which is sent, characterizes playable instruction message, then
Show that external equipment is already prepared in Android Booting sequence, sound output can be carried out, if whole when now last time shuts down
The audio output device of end configuration is external playback equipment, then just switch to external broadcasting to set from loudspeaker in sound broadcasting path
Standby so that in the playing process of startup advertisement, front half section can send sound by loudspeaker, treat that external playback equipment is ready to
