Embodiment
To be elaborated to execution mode of the present invention below.
Existing Android nowadays has been the king in intelligent terminal field, but because the Android complex, and Android immature in intelligent field of set-top scheme; The Android triangular web realizes that dvb plays and the scheme of network player function has difficulties at present.
Intelligent machine top box market urgently one of needs is simple to operate, and the reliable and stable solution that is beneficial to operation again on this platform, can realize the value-added service of enriching.The dual system scheme of outside kernel, switching can satisfy this requirement.
The advantage one that outside kernel, realizes is that broadcasting and TV can management and control; Most of common people only see TV; Linux system is simple to operate, meet traditional use habit, uses linux system just can satisfy their requirement, Android system operation relative complex; Young man or fan can select the more Android system service of individual character, and we provide abundant value-added service selective for this part crowd; The 2nd, stability, at present professional that is that all right is ripe for Android DVB, switches in the outer realization of kernel system, more stable on function realizes.Therefore, digital home of the present invention intelligent terminal is employed in the method that the outer realization of kernel system is switched, at kernel outer setting Flash flag bit.
In this digital home intelligent terminal system, the linux system operation all be basic function such as televise, so linux system is set to give tacit consent to operational system.
Fig. 1 is that the changing method between the system is following in the specific embodiment of the invention,
Step S101, system start-up gets into the system start-up boot.System default gets into linux system; Because the basic business of the integration of three networks still is the broadcast of TV programme or video; Be set to default system so control the linux system of TV and video, just need do not adjust after the entering system like this and can watch TV programme.
Step S102, whether detection in real time has the external signal input, can not switch through front panel keys or remote controller key input carrying out system if the user does not want to get into the acquiescence linux system when start.The mode of front panel keys that the switching between this practical implementation linux system and the Android system is adopted or remote controller key control, the control mode that can certainly adopt bluetooth or other external signals to import.
If the remote controller key input is arranged, then get into step S103, if do not have, then get into step S104.Because the whole steps of this method is the process of a circulation; Step S106 and step S107 are that whether detection in real time carries out the signal that system is switched in system's running; If have and just write the Flash flag bit; Restarting systems judges through step S104 how many values that writes the Flash flag bit is then, selects entering to need the system of switching then.And step S102 just selects to get into which kind of system when to be system begin to start and starts.
Step S103 and step S104 are the processes of one group of Flash flag bit read-write, and when the signal input of system's switching was carried out in the outside, then step S103 write corresponding value according to the signal of front panel or remote controller key input at the Flash flag bit.Because the just switching between two systems of linux system and Android system in this execution mode; So have remote controller key when input need be on the Flash flag bit value of writing, only need whether just can judge that the entering linux system still is the Android system through the set of Flash flag bit.The system of switching if desired is more than three or three, just need on the Flash flag bit, write certain value, and step S104 whenever reads a kind of numerical value then, just starts a kind of corresponding system.The system that so just external remote button and front panel keys and kernel need be started is mapped, and has realized that kernel carries out the switching of system outward.
Step S104 reads the Flash flag bit, selects to pass to the start-up parameter of kernel according to flag bit.Promptly after whether set judged completion to the flash flag bit, selected environmental variance was set to pass to the start-up parameter of kernel.Operation is linux system if desired, and then linuxargs is set to bootargs; Operation is the Android system if desired, and then androidargs is set to bootargs.The bootargs here is exactly the start-up parameter that passes to kernel.
Step S105 is concrete certain the selected system that starts.Step S105 is further comprising the steps of, and step S1051 is that kernel starts corresponding system kernel according to transmitting the start-up parameter of coming among the step S104.If that selected operation is linux system then step S1051 operation linux kernel, step S1052 then moves linux system then, and final step S1053 is operation and the corresponding various application of linux system; If that selected operation is Android system then step S1051 operation android kernel, step S1052 then moves android system then, and final step S1053 is operation and the corresponding various application of Android system.
Step S106, when the operational system application process, system still can detect the external signal input whether switched system is arranged.If in system's running, do not detect and need carry out the external input signal that system is switched, then continue the current system of operation.The current system here is not meant the linux system of acquiescence, and is in service if system is in linux system, and so current system then is a linux system; If switch to the Android system from linux system, so current system is exactly the Android system.No matter which system current operation is, the short of signal input of carrying out system's switching just continue the current system of operation, and whether detection always has the external signal input.After detecting external input signal, step S107 can write the Flash flag bit by the input switching signal, restarts system then, returns step S101.Because this embodiment is the switching between two systems of linux system and Android system, so only need whether to get final product for the set of Flash flag bit among the step S107 here.The system of switching if desired is more than three or three; Then when button is imported; Every kind of button input meeting writes a value at the Flash flag bit; Each value is corresponding with a kind of system, when so just having realized more than three kinds that system is switched, and corresponding between the input of external key signal and the system that needs switching.
Below be two systems switching way back and forth: in the linux system running, " review "+" 0 "+" 1 " (or front panel keys) by remote control keys, set-top box software is promptly given the set of Flash flag bit.Automatically restart STB then, after restarting, the set-top box judging flag bit has set, can get into the Android system, gets into step S105.In the Android system running, " review "+" 0 "+" 1 " by remote control keys, system restarts automatically, and directly get into acquiescence linux system because the flash flag bit does not have set this moment, gets into step S105.
Fig. 2 is for adopting digital home's intelligent terminal structured flowchart of above-mentioned multisystem changing method.201 is system kernel among the figure, and 202 is Flash, and 203 is internal memory, and 204 is power supply, and 205 for LED shows that 206 is the HDMI HDTV, and 207 is phone, and 208 is camera, and 209 is the Femto Home eNodeB, and 210 is bluetooth, and 211 is the Wifi router.
