Embodiment 1
Fig. 1 is the step schematic diagram of the control method for playing back of the EPG video of set-top box in the embodiment of the present invention.
As shown in Figure 1, the control method for playing back of the EPG video of set-top box, which is equipped with responsible JS logic and executes
And execute the browser software subsystem of Broadcast Control logic, which comprises the following steps:
The global of one group of specific keys is arranged in browser software subsystem and plays control indexed variable and sets by step S1
It is set to falsity.
The global control indexed variable that plays that one group of specific keys is arranged in browser software subsystem is falsity, is used for
Whether mark EPG has handled corresponding broadcasting control operation.
Particularly as being that the global of one group of specific keys is arranged in the browser software subsystem of set-top box side to play control mark
Will variable is falsity, i.e., what the third Broadcast Control that cannot be identified in existing full Broadcast Control and half Broadcast Control routine techniques needed: volume tune
Section, mute, F.F., rewind mark, for identifying whether EPG has handled corresponding Broadcast Control operation.
Further, one is also encapsulated when one group of specific global broadcasting control indexed variable is arranged as a kind of optimization
Mark resetting function interface is played in browser software subsystem, which is used to all overall situations playing control mark
Will variable resets to falsity.
Wherein, it when browser software subsystem has detected the load of the EPG page, calls and plays mark resetting function interface
It is reset, all global control indexed variables that plays is reset into falsity.
The above operation solves first problem, realizes to whether the video of EPG has full Broadcast Control or half Broadcast Control function
The judgement of energy.
Step S2, when remote controller key is pressed, if full Broadcast Control, half Broadcast Control, browser software subsystem are directly adjusted
Control is played out with corresponding Broadcast Control logic, and controls corresponding global play of key while calling these Broadcast Control logics
Indexed variable processed is set as true value, is transferred to next step step S3.
EPG page invocation playback interface carries out video playing, when remote controller key is pressed, if the prior art can solve
Full Broadcast Control, half Broadcast Control certainly, browser software subsystem call directly corresponding broadcasting logic, are calling these Broadcast Control logics
True value is set by the corresponding global control indexed variable that plays of key simultaneously, is transferred to next step step S3.
If the EPG page of load is related to live streaming, program request class video playing, browser software subsystem calls related play
Interface carries out video playing.
When user by remote controller key carry out video Broadcast Control, due to remote controller key event include keydown,
Keyup, is keydown event when user presses remote controler, and set-top box side browser software subsystem can execute the EPG page pair
The JS logic answered, if JS has invoked the corresponding Broadcast Control interface of browser software subsystem: setVolume (),
SetMuteFlag (), setFastForward (), setFastRewind (), these interfaces respectively correspond volume adjustment, quiet
Sound, F.F., fast reverse operation, as long as illustrating to need to carry out using the prior art full Broadcast Control, half Broadcast Control namely EPG in broadcast state
Under have invoked relevant Broadcast Control logic, just belong to full Broadcast Control, half Broadcast Control, by existing technology carry out subsequent processing.Meanwhile
It is true value that corresponding global Broadcast Control mark, which is arranged, goes to next step step S3.
Full Broadcast Control, specifically as follows:
The JS logic of EPG includes Broadcast Control processing logic, at the same realized on EPG the corresponding UI of matched Broadcast Control show and
It hides, box end is executed by correlation EPG logic.
Half Broadcast Control, specifically as follows:
The JS logic of EPG includes Broadcast Control processing logic, but EPG do not realize the corresponding UI of matched Broadcast Control show and
It hides, standardizes by IPTV to box end and issue setNativeUIFlag, setMuteUIFlag, setAudioVolumeUIFlag mono-
Group relevant interface mark respectively corresponds the total sign switch of local UI, local mute UI flag bit, local volume UI flag bit etc.,
The total sign switch of local UI that only EPG is issued is just effective in genuine situation.Box end controls and shows this according to correlating markings
Ground UI logic.
Step S3, when remote controller key, which bounces event, to be executed, browser software subsystem judges corresponding global broadcasting
Control whether indexed variable is true value, if it is true value, into S5；Otherwise it is transferred to step S4.
Particularly as being when remote controller key bounces keyup event and executes, browser software subsystem judges corresponding complete
Partial seeding puts control indexed variable, if the global control flag bit that plays of corresponding key is true value, into S5；Otherwise it is transferred to step
S4。
Browser subsystem carries out full Broadcast Control according to existing routine techniques or half Broadcast Control carries out the place of subsequent routine techniques
Reason, enters step S5.Existing routine techniques is exactly to transfer the broadcasting control logic having in corresponding set-top box to play out
Control.
Step S4, when for falsity, browser software subsystem executes at local Broadcast Control logic according to corresponding Broadcast Control key
Reason.
When for falsity, that is, third party's situation that the prior art can not be handled, browser software subsystem is according to correspondence
Broadcast Control key executes local Broadcast Control logical process and UI draws and shows.
It is described local Broadcast Control logic include:
For mute button, encapsulates the mute function Processing Interface in a local and call, obtain the mute shape of current system
State reverts to non-mute state if it is mute；Conversely, reverting to mute state for non-mute；
For volume button, encapsulates a local volume adjustment function Processing Interface and call, obtain the sound of current system
Magnitude is operated if it is volume plus/minus, just often by increasing/reduce a step-length volume next time；
For F.F., fast reverse operation key, encapsulates a local F.F., rewind adjustment function Processing Interface and call chip
F.F., fast reverse operation are realized in the F.F. of bottom, rewind interface.
Particularly for being exactly for set-top box:
The processing logic of mute key local encapsulates the mute function Processing Interface in a local and calls, and obtains current system
Mute state, revert to non-mute state if it is mute；Conversely, reverting to mute state for non-mute.
The processing logic of volume key local encapsulates a local volume adjustment function Processing Interface and calls, obtains current
The volume value of system:
If it is volume add operation, increase volume by each step-length 5 (or other numerical value), when the value for adjusting volume is more than
When IPTV set top box max volume value 100, it is set as 100；
If it is volume reducing, volume is reduced by each step-length 5 (or other numerical value), when the value for adjusting volume is more than
When IPTV set top box minimal volume value 0, it is mute to be set as 0.
The processing logic of skip forward/back key local encapsulates a local F.F., rewind adjustment function Processing Interface and adjusts
With 2 speeds, 4 speeds, 8 speeds, 16 speeds, 32 speeds for executing by remote controller key before etc. switch and call chip bottom
F.F., rewind interface, realize F.F., fast reverse operation.
So realize solution to Second Problem, realize set-top box side accurately according to the remote controler of user by
The Broadcast Control operation of key plays out as expected to control EPG video: volume adjustment, mute, F.F., rewind, it is clear that above to implement
Example only controls the broadcasting of most basic EPG video, other functions, such as the pause that fixes, the amplification of Zoom picture
Or diminution etc. is realized, again may be by encapsulating corresponding function Processing Interface realization, above is only a demonstration example.
Step S5, browser software subsystem detect new EPG load, go to step S1.
