Embodiment
Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
The invention provides a kind of starting method of Digital Television.
With reference to shown in Fig. 1, it is the flow chart of starting method first embodiment of Digital Television of the present invention.
In a first embodiment, the starting method of this Digital Television comprises:
Step S10, after television system kernel starts, runs the first system process with initiating hardware, while operation the first system process, second system process to be run is loaded on internal memory, and wherein, described hardware comprises demodulation, the multiple corresponding hardware of tuning reconciliation.
When digital television starts, first be standbyCPU (standby processor) startup optimization, the time of standbyCPU startup optimization and program store the memory device adopted relation, if adopt jumbo memory device, the time that standbyCPU completes startup optimization is longer, if adopt norflash (nonvolatile storage), the time that standbyCPU completes startup optimization is shorter.After standbyCPU completes startup, television set host CPU (CentralProcessingUnit, central processing unit) power on, after television set host CPU powers on, first can start bootloader (Boot loader), finally start kernel (system kernel), kernel program can carry out follow-up initialization operation after starting.
After detecting that kernel program starts, first the first system process is run with initiating hardware, wherein, described hardware comprises hardware corresponding to demodulation, tuning reconciliation, i.e. demod (demodulator), tuner (tuner) and for the multiple demux (demultplexer) of descrambling solution.Be understandable that, after the peripheral interface of television set should complete initialization, just can carry out the initialization of above-mentioned hardware, otherwise cannot demodulation be carried out, the initialization of the multiple corresponding hardware of tuning reconciliation, the hardware that the peripheral interface of television set is relevant specifically comprises: interrupt, GPIO (GeneralPurposeInputOutput, bus extender), UART (UniversalAsynchronousReceiver/Transmitter, asynchronous receiving-transmitting transmitter), IIC (Inter-IntegratedCircuit, integrated circuit (IC) bus) module initialization, therefore, above-mentioned hardware also belongs to the first system process and needs initialized hardware.
The first system process just exits after having run automatically, and above-mentioned hardware initialization completes, and demod, tuner are in hardware and stablize wait state, and the demux for video (video) module and audio (audio frequency) module also sets; Demod locking after, video stream data by demux filter obtain voice data and video data, be injected in audio decoder and Video Decoder respectively, for follow-up audio decoder and video decode ready.
Step S20, when detecting that described the first system process has been run and described second system process has loaded, runs described second system process to complete the startup of TV.
While operation the first system process, carry out the loading of second system process, it should be noted that, due to second system process, to load the time taken long, such as, on the multinuclear TV platform of current common configuration, the executable file of a 15MB size needs the load time of about about 0.6 second.Generally, the time that the time loading second system process can take than operation the first system process is long, therefore, possible the first system process has been run, this second system process does not also complete loading, now, proceeds the loading of second system process until it has loaded.When the first system process has been run and second system process has loaded, can run second system process, second system process mainly completes other hardware except the hardware of the first system process initialization.
Be understandable that, in the process that the first system process is run, one by one initialization is carried out to hardware, and utilize the time of each hardware of initialization to be loaded in internal memory by second system process, and whether the loading of timing or real-time judge second system process completes, if complete, then carries out the operation of second system process, if do not complete, then proceed the loading of second system process.
Carry out the operation of second system process, mainly to the initialization of lower module, video module, audio module, graphic (display) module, power amplifier module, mixed-media network modules mixed-media, bluetooth module etc.And after carrying out operation the first system process, set demod, tuner.Relative in prior art when TV starts, treat whole process loaded after the mode of reruning, effectively utilize the hardware of demod, tuner to stablize the stand-by period and initialization carried out to other modules, shorten the time of starting shooting and taking.
The starting method of the Digital Television that the present embodiment provides, due to demod, tuner after initialization is complete, wait for stable taking the regular hour, and after these hardware initialization complete, namely can be audio decoder and video decode carries out optimum configurations, for follow-up decoding is ready.Therefore, the hardware broadcast television signal received being carried out to the multiple television programme reception processing section of tuning, demodulation, solution relevant is formed an independent sector, runs as the first system process.And, it is short that the modules such as video module, audio module, graphic module, power amplifier module, mixed-media network modules mixed-media, bluetooth module not only load the time taken, and these modules can carry out initialization again after the work such as tuning, demodulation, Xie Fu completes, therefore the initialization of these modules can be carried out in the running of second system process.When running second system process, without the need to again carrying out the initialization of the hardware that above-mentioned independent sector comprises, second system process committed memory is larger, therefore the time loading needs is long, within the time loading second system process, complete the operation of above-mentioned the first system process simultaneously, save the available machine time, improve starting up speed.
In other examples, also comprise in step S10:
When detecting that described the first system process completes the initialization of described hardware, and when described second system process has not loaded, described the first system process also carries out the optimum configurations of the parameter relevant to channel to be played, audio decoder and video decode
Generally, time shared by time shared by the operation of the first system process can load than second system process is short, but according to the difference of television system configuration, also the situation that the time shared by the time that there will be shared by the operation of the first system process can load than second system process is long, therefore, detecting that the first system process has been run, and second system process has not also loaded, within the time that second system process continues loading, the first system process also carries out the setting of the parameter relevant to channel to be played, the frequency of such as video, symbol rate, the parameters such as demodulation mode, like this, just need not again arrange when running second system process, the toggle speed of further quickening television set.If do not carry out the setting of these parameters in the first system process, in the process running second system process, after completing hardware initialization, need the setting carrying out above-mentioned parameter.But carried out the setting of above-mentioned parameter by second system process, occupy certain available machine time; And utilize the time that second system process loads, carried out the setting of above-mentioned parameter by the first system process, accelerate television boot-strap speed further.
The starting method of the Digital Television that the present embodiment proposes, after television system kernel starts, run the first system process and comprise demodulation, the multiple corresponding hardware of tuning reconciliation with initialization, while operation the first system process, second system process is loaded on internal memory, after second system process has loaded and the first system process has been run, run second system process to complete the startup of TV.Present invention reduces total duration that system initialization takies in TV cold start-up situation, improve the toggle speed of TV.
