Again, multimedia feeding unit 305 with Video Streaming (streaming technology) via the Internet 501 to obtain multi-medium data 307.
What this can remark additionally be, in other possible embodiment, second electronic device 103 can also be multifunctional digital disc (Digital Versatile Disc, a DVD) videocorder, at this moment, multimedia feeding unit 305 can be multifunctional digital disk stores unit.
Fig. 3 represents the flow chart of steps of wireless control method of the present invention.
Herein please be simultaneously with reference to aforesaid icon, symbol and explanatory note.
At first, in step S1, transmitter 101 sends enabling signal 201 and first control signal, 202 to first electronic installations 102 with wireless mode.What this can remark additionally be, transmitter 101 has and starts switch key 401 (seeing also Fig. 1), and the state that can be used to switch enabling signal 201 is ON or OFF.
In step S2, the receiver 301 of first electronic installation 102 receives the enabling signal 201 and first control signal 202 and is sent to first processor 300 with wireless mode.
In judging formula C1, first processor 300 decides the present pattern of first electronic installation 102 according to enabling signal 201.What this can remark additionally be, when the user when starting the state of switch key 401 (seeing also Fig. 1) and switch to OFF with enabling signal 201, the present pattern of first electronic installation 102 is a general modfel.And, when the user when starting the state of switch key 401 (seeing also Fig. 1) and switch to ON with enabling signal 201, the present pattern of first electronic installation 102 is a repeater mode.
If pattern is a general modfel at present, then carry out step S3, the user is for to come remote control first electronic installation 102 by transmitter 101 in expression, and therefore, first processor 300 is carried out the first corresponding action according to first control signal 202.So far, flow process promptly finishes.
If pattern is a repeater mode at present, then carry out step S4, the user is for to come remote control second electronic device 103 by transmitter 101 in expression, and therefore, first processor 300 is converted to first control signal 202 second control signal 203 of RS232 form and is sent to RS232 interface 104.Or rather, first processor 300 is that the infrared ray instruction in first control signal 202 is packaged in second control signal 203 according to the RS232 form.For example, if the instruction of the infrared ray of first control signal 202 is " 0x4C ", represent the user to press " LEFT " key, then second control signal 203 that gets according to the encapsulation of RS232 form promptly is cascadedly combined by following each section: " 0xBE ", " 0xBF ", " Packet Header ", " 0x4C ", " CRC32 checksum ".
At last, in step S5, second processor 304 receives second control signal 203 and carries out the second corresponding action according to this via RS232 interface 104.Or rather, second processor 304 translates the infrared ray instruction that is packaged in second control signal 203 for separating, and carries out the second corresponding action according to separating the infrared ray instruction that translates again.So far, flow process promptly finishes.
Lifting an operational instances below illustrates.
Suppose the user originally for to come remote control first electronic installation 102, that is the present pattern of first electronic installation 102 is a general modfel by transmitter 101.If this moment, user's desire was operated second electronic device 103, so that screen 402 and loud speaker 403 (seeing also Fig. 1) by first electronic installation 102 are viewed and admired the multi-medium data 307 that second electronic device 103 is provided, then this user need carry out following action.
At first, the user presses startup switch key 401 (seeing also Fig. 1) and switches to ON with the state with enabling signal 201 by OFF, and then the user presses " PLAY " key (that is multimedia instruction) of transmitter 101 again, can reach desired result.
The action details of wireless control system 100 in this example is described according to the flow process of wireless control method below.
At first, in step S1, when the user pressed startup switch key 401 (seeing also Fig. 1) and " PLAY " key, transmitter 101 sent enabling signal 201 and first control signal, 202 to first electronic installations 102 with wireless mode.At this moment, the state of enabling signal 201 is ON, and the infrared ray instruction of first control signal 202 is " 0x70 ".
In step S2, the receiver 301 of first electronic installation 102 receives the enabling signal 201 and first control signal 202 and is sent to first processor 300 with wireless mode.
In judging formula C1, first processor 300 learns that via judgement the state of enabling signal 201 is ON, and therefore, the present pattern that can determine first electronic installation 102 is a repeater mode, and expression user desire is come remote control second electronic device 103 by transmitter 101.
Then, in step S4, first processor 300 is converted to first control signal 202 second control signal 203 of RS232 form and is sent to RS232 interface 104.With this example, the infrared ray instruction of first control signal 202 is " 0x70 ", and then second control signal 203 that gets according to the encapsulation of RS232 form promptly is cascadedly combined by following each section: " 0xBE ", " 0xBF ", " Packet Header ", " 0x70 ", " CRC32 checksum ".
In step S5, second processor 304 receives second control signal 203 via RS232 interface 104, and separates and translate the infrared ray instruction that is packaged in second control signal 203 and be " 0x70 ", represents the user to press " PLAY " key.Therefore, second processor 304 indicates multimedia feeding unit 305 to provide multi-medium data 307 to second processors 304 then.Then, (motion picture experts group MPEG) deciphers multi-medium data 307 second processor 304 with Motion Picture Expert Group again.At last, the multi-medium data 307 that will decipher by multimedia interface 105 of second processor 304 is sent to first electronic installation 102.So, second electronic device 103 is promptly reached the function that multi-medium data 307 to first electronic installations 102 are provided by multimedia interface 105.
At last, when the first processor 300 of first electronic installation 102 receives the multi-medium data 307 that is transmitted by multimedia interface 105, multi-medium data 307 can be sent to screen 402 and loud speaker 403 (seeing also Fig. 1), so, the user just can view and admire the multi-medium data 307 that second electronic device 103 is provided by first electronic installation 102.
In the present invention, by installing the RS232 interface additional between first electronic installation and second electronic device, when making the electronic installation of winning receive the instruction that remote controller sends, the operational order that belongs to second electronic device can be packaged into the RS232 control command, deliver to second electronic device via the RS232 interface again, use and reach the effect of coming the remote control second electronic device by first electronic installation.
So, when user's enjoy in Seeing and Hearing equipment at home, and when television set is connected with other audio-visual equipment, the user can only use a remote controller promptly to reach the effect of control television set and another audio-visual equipment, not only can save the trouble that the emission port of remote controller need be aimed at corresponding audio-visual equipment, more increase elasticity and convenience on using, also can save the accommodation space of remote controller simultaneously.
Though the present invention discloses as above with preferred embodiment; but it is not in order to limiting scope of the present invention, anyly has the knack of this skill person, without departing from the spirit and scope of the present invention; all can do a little change and retouching, thus protection scope of the present invention should with claim the person of being defined be as the criterion.
