Embodiment
For making purpose of the present invention, technical scheme and beneficial effect clearer,, the present invention is done detailed description further below in conjunction with embodiment and accompanying drawing.
The method and system of realization equipment complex selectivity provided by the invention standby, when the equipment complex application system determines that equipment complex is in idle condition always in Preset Time length, by changing the identification information of described equipment complex, described equipment complex is identified as single video equipment, and instructs this equipment complex to enter holding state.
The method of realization equipment complex selectivity of the present invention standby comprises: when determining that equipment complex is in idle condition always in default time span, change the identification information of described equipment complex, again enumerate equipment complex, described equipment complex is identified as single video equipment, and instructs this equipment complex to enter holding state.
Here, after described equipment complex is identified as single video equipment, further comprise: the identification information that changes described equipment complex once more, when definite needs are reused described equipment complex, again enumerate equipment complex, equipment complex is identified as again the equipment complex of audio frequency apparatus and video equipment composition.
Fig. 1 is the process flow diagram of the realization equipment complex selectivity idle method of the embodiment of the invention.This flow process comprises the steps:
Here, when the equipment complex application system determines that equipment complex is in idle condition, open a timer, determine whether equipment complex is in idle condition in default time span always.If in the middle of Preset Time length, equipment complex is not used, then execution in step 102; Otherwise, finish this flow process.
Default time span is an arbitrary value, can select between 5 to 15 seconds usually.
The zone bit 0xal that has an equipment complex in the equipment complex identify unit that links to each other with equipment complex in the equipment complex system, when 0xal is that 1 interval scale is supported audio frequency apparatus, then the equipment complex application system is identified as equipment complex the equipment complex that comprises audio frequency apparatus and video equipment.The equipment complex identify unit can be programmable register (E
2Prom).
The equipment complex application system can realize the step that equipment complex is identified as single video equipment by the following method:
The equipment complex application system is changed to 0 with the equipment complex zone bit 0xal in the equipment complex system, and enumerate this equipment complex again, when at this moment equipment complex and equipment complex application system are shaken hands, only transmit the descriptor of single video equipment, the equipment complex application system is identified as single video equipment with equipment complex.
After the equipment complex application system was identified as single video equipment with equipment complex, the equipment complex application system instructed the equipment complex system that the equipment complex flag information is reverted to the preceding information of change again, in this embodiment for 0xal is changed to 1 again.Like this, after equipment complex enters holding state, if equipment complex need be used again, then the equipment complex application system is enumerated this equipment complex again, because zone bit is changed to 1 again, therefore this equipment complex still is identified as the combination of audio frequency apparatus and video equipment, thereby has guaranteed that this equipment complex can normally be used.
After the equipment complex application system is identified as single video equipment with this equipment complex, the equipment complex application system determines that this equipment complex is not used in Preset Time length, then the video equipment to this equipment complex sends the request that enters holding state, and then makes whole equipment complex enter holding state.Here Preset Time length is an arbitrary value, can select in the scope at 5 to 15 seconds usually.
Fig. 2 is the structural representation of the realization equipment complex selectivity standby system of the embodiment of the invention.This system comprises: equipment complex system and equipment complex application system.
Wherein, the equipment complex system comprises the equipment complex of being made up of audio frequency apparatus and video equipment, and the equipment complex identify unit, and the equipment complex application system comprises console controller, video device driver unit.
When console controller determined that equipment complex is in idle condition, this equipment complex of notice video device driver unit was in idle condition;
The video device driver unit knows that this equipment complex is in idle condition, and when determining that this equipment complex is in idle condition always in Preset Time length, by the equipment complex identification information in the console controller notice equipment complex change equipment complex identify unit, again enumerate this equipment complex, this equipment complex is identified as single video equipment, and sends the request that video equipment enters holding state to console controller.
After the video equipment that console controller reception driver unit sends enters the request of holding state, confirm that this equipment complex can enter holding state, and send the instruction that changes this equipment complex power supply status, make this equipment complex enter holding state.
In this embodiment, the video device driver unit further can be used for after equipment complex is identified as single video equipment, again recover equipment complex identification information in the equipment complex identify unit by console controller instruction equipment complex, when determining to reuse this equipment complex, again enumerate equipment complex, equipment complex is identified as the combination of video equipment and audio frequency apparatus again, guarantees that equipment complex is normally used.
Described equipment complex identify unit can be programmable storage (E
2Prom).It is 0 with the equipment complex mark position in the programmable storage that equipment complex can be notified by console controller in the video device driver unit, and enumerate the equipment that equipment complex comprises again, equipment complex is identified as single video equipment, and after equipment complex is identified as single video equipment, the instruction equipment complex is changed to 1 again with the equipment complex zone bit of programmable storage, and sends the request that video equipment enters holding state to usb host controller.
Described video device driver unit is after being identified as single video equipment with equipment complex, before the usb host controller unit sends equipment complex and enters the request of holding state, be further used for determining whether equipment complex is in idle condition always in Preset Time length, when determining to be, send the request that equipment complex enters holding state to usb host controller.
As shown in Figure 2, equipment complex application system among this embodiment further can comprise a timer, this timer can be used as the part of video device driver unit, be arranged on inside, video device driver unit, also can be arranged on the video drive unit outside separately, link to each other, when the video device driver unit knows that equipment complex is in idle condition with the video device driver unit, open this timer, determine whether equipment complex is in idle condition in Preset Time length always; If equipment complex is used in Preset Time length, then instruction timer in video device driver unit makes zero.
In a word, the above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
