Detailed Description
The present invention is further illustrated by the following examples, which are not to be construed as limiting the invention thereto.
Referring to fig. 1, the embodiment provides an embedded smart antenna module of a smart tv, an embedded smart antenna module 2 of the smart tv is installed in a smart tv 1, and the smart tv 1 and a wireless device 3 are both installed in a spatial domain, such as a building indoor domain, e.g., a living room, a bedroom, an office, an exhibition space, a hall, etc. The embedded smart antenna module 2 transmits and receives signals using a wlan compliant with IEEE 802.11 standard, for example, following the conventional wifi (wireless fidelity) wireless authentication specification. The embedded smart antenna module 2 includes a plurality of antennas 21, a wireless chip 22, a control unit 23, and an application unit 24. The dual antennas 21 are connected to the wireless chip 22, and have dual antenna modes, wherein the wireless chip 22 has dual Modulation and Coding Schemes (MCS), and the wireless chip 22 selects any one of the dual modulation and coding schemes and uses the dual antennas 21 to transmit and receive wireless signals to and from the wireless device 3. The control unit 23 is connected to the dual antennas 21 for controlling the dual antenna mode. Also, the control unit 23 is preferably a Microcontroller (MCU) independent of the wireless chip. The application unit 24 connects the wireless chip 22 and the control unit 23, and has a traffic monitoring server 241, and the traffic monitoring server 241 is preferably installed in the Linux operating system of the smart tv 1. The application unit 24 switches the dual antenna mode by means of the control unit 23. Based on the modulation and coding scheme selected by the wireless chip 22, the application unit 24 uses the traffic monitoring server 241 to obtain the physical data rate (phy data rate) corresponding to each antenna pattern. Based on the modulation and coding scheme selected for use by the wireless chip 22, the application unit 24 stores the even number of physical layer data rates corresponding to the even number of antenna modes as mode sampling information. Based on the modulation and coding scheme selected by the wireless chip 22, the application unit 24 selects the antenna mode corresponding to the highest of the double physical layer data rates as the preferred antenna mode according to the mode sampling information. The traffic monitoring client 4 obtains the monitoring status of the traffic monitoring server 241 according to the wireless device 3, and the remote control application unit 24 selects the preferred antenna mode. The traffic monitoring client 4 is connected to the traffic monitoring server 241 by the wireless device 3, the traffic monitoring client 4 can be a device independent from the wireless device 3, the traffic monitoring client 4 can be installed in the wireless device 3 instead, and the following embodiments of fig. 2 and 3 will be illustrated.
The basis for selecting the preferred antenna mode may be based on throughput (throughput) or physical layer data rate. The performance of the smart tv 1 for wirelessly receiving the video information is influenced by the location of the wireless signal source (the wireless device 3) in the spatial domain, and also by the location of the wireless signal source in the spatial domain, and the environmental status of the spatial domain may also be dynamically changed, which may be different as a preferred (or optimal) antenna mode according to the different locations of the spatial domain and the possible changes of the environmental status, so the embodiment of the present invention sets a mechanism for re-selecting the preferred antenna mode. In this embodiment, the testing mode is executed first, the traffic monitoring server 241 uses the dual antennas 21 to receive the field testing signal (Fn) (e.g. a segment of audio/video information for testing) from the wireless device 3 to execute the field testing mode at the testing position, and obtains the field testing Throughput (TF) and the field testing physical layer data rate (PF) of the field testing mode, and the application unit 24 stores the relation ratio of the field testing Throughput (TF) and the field testing physical layer data rate (PF), i.e. TF/PF. Then, when the smart tv 1 is operating normally (displaying tv video), the traffic monitoring server 241 receives the remote signal (tv video) from the wireless device 3 by using the dual antennas 21 to execute the working mode at the testing position, and obtains the working mode Throughput (TW) and the working mode physical layer data rate (PW) of the working mode, and the application unit 24 multiplies the working mode physical layer data rate (PW) by the relation ratio (TF/PF) to obtain the Target Throughput (TT). The Target Throughput (TT) is an upper limit value of the expected throughput obtained in the field test mode, and can be formulated as: TT ═ PW × TF/PF. The application unit 24 monitors whether the operating mode Throughput (TW) is below the Target Throughput (TT) and does not need to pick a preferred antenna mode again when the operating mode Throughput (TW) is above or equal to the Target Throughput (TT). When the operating mode Throughput (TW) is below the Target Throughput (TT), the application unit 24 reselects the preferred antenna mode.
Further, when the operating mode Throughput (TW) is lower than the Target Throughput (TT), there are two different determination mechanisms depending on the degree of difference between the operating mode Throughput (TW) and the Target Throughput (TT). When the working mode Throughput (TW) is lower than the Target Throughput (TT) and the difference between the working mode Throughput (TW) and the Target Throughput (TT) is greater than or equal to a predetermined value (Δ), which indicates that more adjustment is needed, the application unit 24 changes the modulation and coding scheme selected by the wireless chip 22, and selects the antenna mode corresponding to the highest physical layer data rate in the mode sampling information as the updated preferred antenna mode based on the changed modulation and coding scheme. When the working mode Throughput (TW) is lower than the Target Throughput (TT) and the difference between the working mode Throughput (TW) and the Target Throughput (TT) is smaller than the preset value (Δ), the application unit 24 reselects the preferred antenna mode according to the Received Signal Strength Indicators (RSSI) and the signal-to-noise ratio (SNR) of the dual number of antennas 21 obtained by the wireless chip 22, for example, selects the antenna mode having the smallest difference amplitude of the received signal strength indicators of all the antennas 21 as the preferred antenna mode or selects the antenna mode having the largest signal-to-noise ratio as the preferred antenna mode. For the details of the above mode sampling information, for example, the field test Throughput (TF) and the field test physical layer data rate (PF) may be stored together with the reception status parameter values (such as the received signal strength indication, the signal-to-noise ratio, etc.) of the dual antennas 21. In practice, for example, a Look-Up Table (LUT) may be stored, each entry of the LUT including values of the status parameters of the antenna 21 for TF, PF (and TF/PF) and corresponding received signal strength indication, signal-to-noise ratio, etc. Furthermore, the derived field test Throughput (TF), field test physical layer data rate (PF), and relationship ratio (TF/PF) can also be computed by interpolation or extrapolation based on known pattern sampling information.
Further, referring to fig. 2, in an embodiment, the wireless device 3 may be a wireless access point, the traffic monitoring client 4 and the smart tv 1 are respectively connected to the wireless access point, and the traffic monitoring client 4 is, for example, a smart phone (or a personal computer), which is also installed in the spatial domain. The traffic monitoring user terminal 4 transmits the field test signal Fn to the smart tv 1 located at the testing position via the wireless access point, in other words, the smart phone transmits the field test signal Fn to the smart tv 1, wherein the field test signal Fn is transmitted via the wireless access point. The domain test signal Fn may be the video information stored by the traffic monitoring client 4 itself, or the external video information Fn' (e.g. video streaming, cloud or online movie) obtained from outside the spatial domain. Furthermore, the smart tv 1 may also be disposed at a plurality of testing locations of the spatial domain to obtain and store a plurality of field testing Throughputs (TFs) and a plurality of field testing physical layer data rates (PFs).
In another embodiment, referring to fig. 3, the wireless device 3 may be a wireless access point, and the traffic monitoring client 4 is installed in the wireless access point, where the traffic monitoring client 4 is, for example, an application program of the wireless access point. The traffic monitoring client 4 uses the wireless access point to transmit the field test signal Fn to the smart tv 1, where the source of the field test signal Fn is the external video information Fn' (e.g. video stream, cloud or on-line film) obtained from outside the spatial field. The smart tv 1 is configured to be disposed at a plurality of testing locations of the spatial domain to obtain and store a plurality of field testing Throughputs (TFs) and a plurality of field testing physical layer data rates (PFs). The traffic monitoring client 4 of the embodiment of fig. 3 may be a smart phone (or a personal computer) and establish a connection with the wireless access point 3. In addition, no matter whether the traffic monitoring user terminal 4 is installed in the wireless access point or not, or whether the traffic monitoring user terminal 4 is a smart phone (or a personal computer) connected to the wireless access point, preferably, in order to achieve a better testing effect, in the field testing mode, the traffic monitoring user terminal 4 transmits a field testing signal Fn to the smart tv 1 by using the wireless access point to perform a full load test.
Furthermore, according to the logic of the usage situation and the control flow, to improve the wireless receiving effect of the smart television 1, referring to fig. 4, the present embodiment provides a control method of an embedded smart antenna module of a smart television, including the following steps. First, step S110 is performed to locate both the smart tv 1 and the wireless device 3 in the same spatial domain, that is, to locate the smart tv 1 in a test position in the spatial domain. Such as offices, parking lots, restaurants, residences, malls. The wireless device 3 is, for example, a wireless access point, and the television signal source of the smart television 1 is the wireless access point. Then, step S120 is performed, in which the wireless chip 22 selects any one of the plurality of modulation and coding schemes and uses the plurality of antennas 21 to transmit and receive wireless signals to and from the wireless device 3. Wherein the application unit 24 switches the dual antenna mode by means of the control unit 23. Then, in step S130, based on the modulation and coding scheme selected by the wireless chip 22, the application unit 24 uses the traffic monitoring server 241 to obtain the phy data rate corresponding to each antenna pattern. Then, in step S140, the application unit 24 stores the even number of phy data rates corresponding to the even number of antenna modes as mode sampling information based on the modulation and coding scheme selected by the wireless chip 22. Then, step S150 is performed, based on the modulation and coding scheme selected by the wireless chip 22, the application unit 24 selects the antenna mode corresponding to the highest of the double physical layer data rates as the preferred antenna mode according to the mode sampling information.
In step S150, the method can be divided into several sub-steps: in step 151, it is determined whether the operating mode Throughput (TW) is lower than the Target Throughput (TT). When the operating mode Throughput (TW) is higher than or equal to the Target Throughput (TT), it returns to step S151. When the operation mode Throughput (TW) is lower than the Target Throughput (TT), the determination of step S152 is performed, and a difference between the operation mode Throughput (TW) and the Target Throughput (TT) is determined. When the difference between the working mode Throughput (TW) and the Target Throughput (TT) is greater than or equal to a predetermined value (Δ), step S153 is performed, the application unit 24 changes the modulation and coding scheme selected by the wireless chip 22, and selects the antenna mode corresponding to the highest phy data rate from the mode sampling information as the updated preferred antenna mode based on the changed modulation and coding scheme. When the difference between the operating mode Throughput (TW) and the Target Throughput (TT) is smaller than the predetermined value (Δ), step S154 is performed, and the application unit 24 reselects the preferred antenna mode according to the received signal strength indication and the signal-to-noise ratio of the dual antennas 21 obtained by the wireless chip 22. The manner for the application unit 24 to reselect the preferred antenna mode according to the received signal strength indication and the signal-to-noise ratio of the dual antennas 21 obtained by the wireless chip 22 is, for example: the difference value of the received signal strength indications of each antenna 21 is determined in each antenna mode, and the antenna mode with the smallest difference value is selected as the updated preferred antenna mode. For another example, the snr of each antenna 21 is determined for each antenna pattern, and the antenna pattern having the largest average snr of all antennas 21 is selected as the updated preferred antenna pattern.
Next, after step S153 or step S154, step S160 is performed, in which the traffic monitoring client 4 obtains the monitoring status of the traffic monitoring server 241 according to the wireless device 3, and the remote control application unit 24 selects the preferred antenna mode. In step S160, the user can monitor or configure the embedded smart antenna module 2 of the smart tv 1, for example, using a smart phone as the traffic monitoring client 4, or monitoring the embedded smart antenna module 2 by using the traffic monitoring client 4 installed in the wireless access point. After each time the position of the smart tv 1 in the spatial field is changed, the steps S120 to S160 may be performed again, so that the wireless receiving effect of the smart tv 1 at any position is optimized. Moreover, each time step S110 to step S140 are executed, each testing location may also use the wireless indoor positioning technology to obtain the positioning point, and the data of the positioning point and the corresponding relation ratio may be stored together, if the mode sampling information is stored in the lookup table, each data of the lookup table includes TF, PF, TF/PF, and the corresponding positioning point.
In summary, the embodiment of the present invention provides an embedded smart antenna module for a smart tv, which can select the best antenna mode of all antenna modes as a preferred antenna mode based on a mode sampling means based on the variable conditions facing the usage environment space and matching with the specification conditions of the modulation and coding mechanism selected during the operation of the wireless chip, thereby significantly contributing to the improvement of the long-term average speed and stability of the wireless transmission data rate of audio and video data, and having a high industrial application value in the aspect of smart tv products. The traffic monitoring client can be a mobile phone or a personal computer of a user, and the traffic mode sampling can be performed by the wireless access point, and the mobile phone (or the personal computer) of the user can also be utilized to take into account two flexible situations that the smart television can receive video from a common (common indoor fixed-point) wireless access point or a device (such as a mobile phone) carried by the user can receive the video, so that the traffic monitoring client is a user experience quality improvement scheme considering the flexible application level.
