It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the prior art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.
The first problem to be considered in wireless home theaters is that low delay is required, for example, wireless transmission technologies such as bluetooth or Wifi, which have large delay, may cause the problem that the sound and the picture are not synchronous when watching the movie. To wireless home theater, the influence of the placement position of the sound box equipment on the sound effect is quite large, but general users do not know how to place the sound box equipment.
Based on this, the present invention provides a method for implementing wireless multi-channel home theater based on UWB, as shown in fig. 1, comprising the steps of:
s10, the wireless multichannel home theater comprises a display device and a sound box device, and both the display device and the sound box device are provided with UWB chips;
s20, manufacturing a UWB tag, and simulating the watching position of a human by the placement position of the UWB tag;
s30, displaying the appointed placement position of the sound box device on the display device according to the placement position of the UWB tag;
and S40, correspondingly placing the sound box equipment to the specified placement position of the sound box equipment displayed on the display equipment, so as to realize the wireless multi-channel home theater.
In the present embodiment, Ultra Wide Band (UWB) is a carrier-free communication technology, and data is transmitted by using a non-sinusoidal narrow pulse on the order of nanoseconds to picoseconds. By transmitting very low power signals over a wide frequency spectrum, UWB can achieve data transmission rates of hundreds of Mbit/s to Gbit/s over a range of about 10 meters. Unlike conventional wireless systems with relatively narrow bandwidths, such as bluetooth and WLAN, UWB can transmit a series of very narrow, low-power pulses over a wide frequency range. The wider frequency spectrum, lower power, pulsed data, means that UWB causes less interference than traditional narrowband wireless solutions and can provide comparable performance to wired in an indoor wireless environment. UWB has the following characteristics:
high-speed data transmission, in civil goods, the transmission range of UWB signals is generally required to be within 10m, and then the transmission rate can reach 500Mbit/s according to a modified channel capacity formula, so that the high-speed data transmission is an ideal modulation technology for realizing personal communication and wireless local area networks. UWB trades a very wide frequency bandwidth for high-speed data transmission and shares the frequency bands used by other wireless technologies, not just the already crowded frequency resources.
The impulse has high positioning precision, and the ultra-wideband radio communication is adopted, so that the positioning and the communication are easily integrated, which is difficult to realize by the conventional radio. The ultra-wideband radio has extremely strong penetration capability, can carry out accurate positioning indoors and underground, and the GPS positioning system can only work within the visual range of a GPS positioning satellite; unlike GPS, which provides absolute geographic location, ultra-short pulse locators can give relative positions with positioning accuracy on the order of centimeters, and ultra-wideband radio locators are cheaper.
The embodiment utilizes the high-speed data transmission performance and the accurate positioning performance of the UWB, that is, the UWB has low delay and AOA (angle of arrival) characteristics, and the UWB chips are mounted on the display device and the speaker devices, so that the display device can know the exact position of each speaker device to transmit the audio required by the speaker device, and can guide the user to place the speaker device at the specified position with the optimal sound effect according to the position information obtained by the UWB, so that the wireless multichannel home theater can achieve the optimal sound effect.
In some embodiments, the step of displaying the designated placement position of the speaker device on the display device according to the placement position of the UWB tag comprises:
pre-establishing a standard corresponding mapping table of a viewing position corresponding to a designated placement position of sound box equipment, and storing the standard corresponding mapping table into the display equipment;
the display equipment acquires the current placement position of the UWB tag and takes the current placement position as a current viewing position;
and the display equipment finds and displays the appointed placing position of the sound box equipment according to the current placing position of the UWB label and the standard corresponding mapping table.
In this embodiment, the sound box device is a dolby sound 5.1 device or a dolby sound 7.1 device, but is not limited thereto. The Dolby sound effect is that four-channel stereo sound is synthesized into two channels by a specific coding means when being recorded, namely 4 signals of original left channel (L), right channel (R), middle channel (C) and surround channel (S) are synthesized into LT and RT composite dual-channel signals after being coded, the coded dual-channel composite signals LT and RT are reduced into four independent signals which are not coherent with each other and are amplified and then are respectively input into a left sound box, a right sound box, a middle sound box and a surround sound box when being replayed. Dolby directional logic surround sound uses left and right surround sound boxes, output from amplifiers, for playback symmetry, so the output of dolby directional logic surround sound is commercially referred to as five channels. However, since the left and right surround sound boxes are connected to one channel, the same surround channel information is output, and thus, four channels are still substantial. There are also six-channel and seven-channel dolby directional logic AV amplifiers in commerce. The six-channel is that the central channel is output by two amplifying circuits and is respectively connected with the left middle sound box and the right middle sound box. However, the left and right center speakers are connected to a center sound channel, so they are also four sound channels in nature. The seven channels divide the surround sound channel into four channels for output, namely, left rear surround sound and right rear surround sound, and four surround sound boxes are respectively adopted, so that seven-channel output is achieved. However, four surround speakers for seven-channel output are connected to one surround channel, and only four-channel output is possible. The AV amplifier with dolby directional logic decoder is therefore essentially four channel, whether it is five channel output, six channel output or seven channel output. The frequency range of the left, middle and right channels of dolby directional logic surround sound can reach 20-20000Hz, which can meet the requirement of full range, but the frequency range of surround sound channels is narrower, and only 100-7000Hz is provided.
In this embodiment, the dolby 5.1 device includes a left front speaker, a right front speaker, a center speaker, a left surround speaker, a right surround speaker, and a subwoofer. The Dolby sound effect 7.1 equipment comprises a left front sound box, a right front sound box, a middle sound box, a left surround sound box, a right surround sound box, a left rear sound box and a right rear sound box.
Taking dolby sound 5.1 equipment as an example, after a display device is installed, the specified installation positions of each loudspeaker box device in the dolby sound 5.1 equipment are changed along with the viewing position of a person, that is, the viewing position and the specified installation positions of each loudspeaker box device are recognized to establish a standard corresponding mapping table, and the standard corresponding mapping table is stored in the display device. In the embodiment, a UWB tag is manufactured, and the placement position of the UWB tag simulates the viewing position of a person, because the optimal placement position of the speaker device is determined according to the viewing position of the person, the placement position of the UWB tag is the so-called golden position. After the UWB tag is placed, the display device can acquire the current placement position of the UWB tag and serve as the current viewing position; and the display equipment finds and displays the appointed placing position of the sound box equipment according to the current placing position of the UWB label and the standard corresponding mapping table. As shown in fig. 2, the display device can obtain and display the current position of each sound box and the current position of the UWB tag, and simultaneously display the specified installation position of each sound box according to the current placement position of the UWB tag, as shown by a circle in fig. 2, a user can move and install each sound box according to the specified installation position of each sound box displayed in the display device, thereby obtaining an optimal sound effect.
As shown in fig. 3, fig. 3 is an installation schematic diagram of the dolby sound effect 7.1 device, and similarly, the display device can acquire and display the current position of each sound box and the current position of the UWB tag, and simultaneously display the specified installation position of each sound box according to the current placement position of the UWB tag, and a user can move and install each sound box according to the specified installation position of each sound box displayed in the display device, so as to acquire an optimal sound effect.
In some embodiments, the UWB location includes a plurality of algorithms including TOA (time of arrival) location, TDOA (time difference of arrival) location, and AOA (angle of arrival) location. The TOA (time of arrival) positioning is to measure the light propagation time between a UWB positioning terminal and a plurality of UWB positioning base stations, and at least three positioning base stations are needed to accurately position the terminal by using the trilateration method, and a straight line and a visual state must be maintained between the positioning base stations and the positioning terminal. TDOA is based on time difference of arrival positioning, and a precise time synchronization function is required in the system. The time synchronization is performed through a wire, the wire time synchronization can be controlled within 0.1ns, the synchronization precision is very high, but all devices adopt a central network mode or a cascade mode due to the adoption of the wire, the complexity of network maintenance is increased, the complexity of construction is also increased, and the cost is increased. Moreover, a special wired time synchronizer is arranged in the system, so that the cost is high; the other method is to perform time synchronization wirelessly, the wireless synchronization can generally reach 0.25ns, the accuracy is slightly less than that of wired time synchronization, but the system is relatively simpler, the positioning base station only needs to supply power, and the data return can be realized in a WiFi mode, so that the cost is effectively reduced. Generally, AOA positioning calculates an arrival angle based on a phase difference method, and because AOA involves a problem of angular resolution, if AOA positioning is performed simply, the positioning accuracy is higher as the AOA is closer to a base station. In this embodiment, it is preferable to acquire the current placement position of the UWB tag and the placement positions of the speakers by AOA positioning.
In some embodiments, the correspondingly placing the speaker device at the designated placement position of the speaker device displayed on the display device includes:
if the current loudspeaker box cannot be placed at the specified placement position of the loudspeaker box equipment, sending an instruction that the current loudspeaker box cannot be moved to the display equipment;
the display equipment automatically modifies the updated placement position of another sound box corresponding to the current sound box according to the instruction;
and placing the other sound box to an updated placing position to realize the wireless multi-channel home theater.
In this embodiment, if the specified placement position of the speaker device displayed in the display device is that the speaker cannot be placed, the user may send an instruction that the current speaker cannot be moved to the display device, that is, it may be set in the display device that a certain speaker cannot be moved at present, and then the display device may automatically modify another speaker to set the optimal placement position. As shown in fig. 4, the sound box at the left circle position is the closest designated position that the user can swing at present, and after sending an instruction to the display device through a remote controller or other input methods, the display device can automatically modify the updated placement position of another sound box corresponding to the current sound box and display the updated placement position, as shown in the right circle in fig. 4, at this time, the sound box at the right side of the right circle in fig. 4 is installed to the right circle, and the optimal sound effect of the wireless multichannel home theater can be realized.
In some embodiments, after all the speaker devices are fixed according to the designated placement positions, the system automatically sets sound effect parameters according to the placement positions of the speaker devices, and adjusts the optimal output sound at the placement positions.
In some embodiments, the display device is a flat panel television, but is not limited thereto.
In some embodiments, the display device includes a projector and a projection screen, but is not limited thereto.
In some embodiments, a system for realizing wireless multi-channel home theater based on UWB is further provided, wherein the system comprises a display device, a sound box device and a UWB tag, and UWB chips are mounted on the display device and the sound box device; the UWB tag is used for simulating a human viewing position; the display device is used for displaying the appointed placing position of the sound box device.
The system provided by the embodiment utilizes the AOA (angle of arrival) technology of UWB to obtain the direction and distance of the sound box equipment, and then guides a user to place the sound box equipment at the optimal position through the display and interaction of the display equipment; after the placement position is determined, the system can know which sound box belongs to which sound channel, so that the sound channel is distributed to the appointed sound box, and the optimal sound effect parameters can be automatically set through the positions of the sound boxes, so that people at fixed positions can obtain the optimal sound.
In the system provided in this embodiment, Ultra Wide Band (UWB) is a carrier-free communication technology, and data is transmitted by using a non-sinusoidal narrow pulse on the order of nanoseconds to picoseconds. By transmitting very low power signals over a wide frequency spectrum, UWB can achieve data transmission rates of hundreds of Mbit/s to Gbit/s over a range of about 10 meters.
