Embodiment
Fig. 2 to Fig. 6 of the present invention with reference to being suitable for is described in detail as follows.
In the configuration of home theater inscape, the position of each channel loud speaker and user's positional information are that the household audio and video system sound equipment is reached optimized key factor.Therefore, utilize communication, real-time media stream tranmission techniques and " location recognition " function of UWB (UWB:Ultra Wide Band) to be applicable to home theater in the present invention.
Household audio and video system is same as shown in Figure 1 basically, and its formation comprises: digital audio/video (A/V) source apparatus 11, display 12, AV receiver 13 and multichannel loudspeaker apparatus 14A-14F.In the household audio and video system of the present invention, utilize the topological structure of wireless connections AV receiver 13 and each loudspeaker apparatus 14A-14F, vision signal transmits by radio display, in addition, with the relative position of each channel loudspeaker apparatus 14A-14F of AV receiver 13 and the positional information of user's input is basis, regulate sound equipment amplitude and time of delay among each channel loudspeaker apparatus 14A-14F, the sound equipment performance of household audio and video system is reached optimization.
Fig. 1 shows is stream operation and operational elements according to wireless network in the household audio and video system of the present invention.Here, all devices comprises the UWB receiving device (tranceiver) of posting a letter, and is equipped with radio network functions.In addition, above any one all (for example: PNC) must be equipped with master control (master) function in utilizing the network of UWB in the said A/V source apparatus 11, display 12, AV receiver 13, in addition, above the high definition characteristic of said each equipment utilization UWB, for the information of particular frame form can sensing equipment between time of delay of distance.
Above said A/V source apparatus 11 include the medium that can store the stream of forming by various compression digital audio frequencies and video content.It mainly is made up of PVR (PVR:Personal Video Recorder) or DVDP (DVDP:Digital Video Disc Player) or STB (STB:Set-Top Box).Above said A/V source apparatus 11 with the compression vision signal be sent to display 12, Ya Suo audio signal is sent to top said AV receiver 13 similarly.
Above said each channel loudspeaker apparatus 14A-14F be connected with the AV receiver by wired, but be connected by radiolink, the synchronizing signal that provides with AV receiver 13 conforms to, and generates audio signal.In addition, in household audio and video system,, regulate sound equipment size and time of delay in the control device of portion within it according to the position of each channel loudspeaker apparatus 14A-14F and user's position.(with reference to Fig. 3)
In AV receiver 13,, need positional information and the user's positional information of its loudspeaker apparatus 14A-14F for regulating time of delay and the sound equipment size of each channel loudspeaker apparatus 14A-14F.Above said user's positional information be in AV receiver 13, to input to microprocessor 22 by user's interface 21 according to the user.Above the positional information of said loudspeaker apparatus 14A-14F refer to the relative distance of 13 of each loudspeaker apparatus 14A-14F and AV receivers and the relative distance between its loudspeaker apparatus 14A-14F.
Above said AV receiver 13 for obtaining top said positional information, use is applicable to the mac frame information of UWB emitter/receiver 27, for loudspeaker apparatus 14A-14F, transmit self and the distance between them and between them range determination require information.
The above-mentioned range determination that receive to transmit require each loudspeaker apparatus 14A-14F of information be to remove other loudspeaker apparatus self and AV receiver 13 respectively transmitting range mensuration require information.To be time of delay, the positional information form of obtaining is sent to AV receiver 13 according to the distance of calculating separately.
For example, with Fig. 5 and shown in Figure 6 identical, require information if receive the range determination that transmits from AV receiver 13 with corresponding first loud speaker of loudspeaker apparatus 14A, its just to other loudspeaker apparatus (2nd Speaker-nth Speaker) and AV receiver 13 respectively transmitting range measure and to require information ProbeLocation (), requiring the time of delay of information with range determination is basis, calculate distance separately, this positional information form of obtaining is sent to AV receiver 13.
Certainly, other loudspeaker apparatus 14B-14F also obtains the positional information form with above-mentioned loudspeaker apparatus 14A method together, is sent to AV receiver 13.
Fig. 4 is the requirement of AV receiver 13 according to the user, for obtaining the processing procedure schematic diagram of positional information.
Promptly, if the user is by specific keys, all loudspeaker apparatus 14A-14F confirm whether be effective (active) state, if not the words that are in effective status, user's interface screen is gone up and is shown error message, if be judged as effective status, require information SetUpLocation () to each loudspeaker apparatus 14A-14F transmitting range mensuration.(S1-S4)
This all loudspeaker apparatus 14A-14F is measured the distance that requires, if successful mensuration transmits the OK signal to AV receiver 13.(S5)
At this moment, said AV receiver 13 is for obtaining the positional information form, to the loudspeaker apparatus transmitting range information requirements information GetLocationinfor () that transmit the OK answer signal above.(S6)
Afterwards, above said AV receiver 13 have and sequentially receive the positional information form that transmits from each loudspeaker apparatus 14A-14F, and take this as a foundation, calculate the position of each loudspeaker apparatus 14A-14F, result calculated is shown on the interface screen.(S7、S8)
In addition, in other embodiments of the invention, identical with top explanation, be not to use the person directly to import user's positional information, but utilize remote controller, by with top similar method, calculate user's position, according to result calculated, regulate sound equipment amplitude and time of delay, reach best acoustics.Be described in detail with reference to Fig. 7 to Figure 10 is following.
Same as shown in Figure 7, household audio and video system has appended remote controller 15, and this is not to utilize and the common identical ultraviolet signal of remote controller, and is same as shown in Figure 8, utilize UWB emitter/receiver 85, the remote controller that communicates with AV receiver 13 and each loudspeaker apparatus 14A-14F.
The user is the position that requires to retrieve automatically self, if press specific keys in the remote controller 15, will be sent to AV receiver 13 with remote controller 15 corresponding information.(ST1)
The AV receiver 13 that receives the information that transmits confirms whether all loudspeaker apparatus 14A-14F are in effective status, if not effective status, on user's interface screen of remote controller 15 or AV receiver 13, show error message, if be judged as effective status, transmit the required distance information (SetUpLocation ()) that distance is measured between each loudspeaker apparatus 14A-14F that requires to remote controller 15.(ST2-ST4)
To this, remote controller 15 is same as shown in Figure 10, and the distance of mensuration and each loudspeaker apparatus 14A-14F if measurement operation completes successfully, transmits the OK signals to AV remote controller 13.(ST5)
At this moment, above said AV receiver 13 be the position information form for receiving the range determination result who transmits from remote controller 15, transmitting range information requirements information.(ST6)
Afterwards, above said AV receiver 13 be basis with the positional information form, be made into set information separately, transmit to each loudspeaker apparatus 14A-14F, and each loudspeaker apparatus 14A-14F is a basis to receive the information that transmits thus, and sound equipment time of delay and size are set.(ST7)
Simultaneously, said AV receiver 13 display position information on user's interface screen of remote controller 15 or AV receiver 13 above.(ST8)
By above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.
Therefore, the technical scope of this invention is not limited to the content on the specification, must determine its technical scope according to interest field.
