[0002] Digital TV services using wired or wireless communication networks are becoming common. Digital TV services can provide a variety of services that existing analog broadcasting services cannot provide.

[0003] For example, in the case of IPTV (Internet Protocol Television) and smart TV (smart TV) services, which are digital TV service types, bidirectionality is provided so that users can actively select the type of program to watch, the viewing time, etc. IPTV and smart TV services can also provide various additional services based on this bidirectionality, such as Internet search, home shopping, online games, etc.

[0004] Recently, a TV service is being provided via a wireless system, in which an A / V transmission device transmits a compressed A / V (Audio / Video) signal to an A / V receiving device via a wireless connection, and the A / V receiving device restores and outputs the compressed A / V signal.

[0005] In the case of a wireless system, RF (Radio Frequency) communication is performed between an A / V transmission device and an A / V reception device via antennas, so the arrangement position relationship between the transmission antenna and the reception antenna is important for wireless quality.

[0006] Generally speaking, the A / V transmission device is located in front of the A / V receiving device, but due to the direction in which the transmitting antenna of the A / V transmission device is placed, the signal may be transmitted through the side antenna.

[0007] In this case, the signal strength is relatively weak. Although the signal strength can be improved by increasing the number of transmission antennas in the A / V transmission device, there is a problem of increased power consumption.

[0008] In addition, in the prior art, in the process of dealing with the customer's user installation environment, SVC (SerVice Center) guidance is carried out based on the extraction and analysis of user logs.

[0009] However, the method of visiting the consumer's home to check the installation environment and changing to the optimal wireless installation condition or providing the installation guide by contacting the consumer may cause inconvenience caused by the change of the initial installation environment or the box position.

The information for adjusting the direction may include one or more of a tilt angle or a translation angle of the transmission antenna.

[0174] In this case, the processor 190 may generate a direction setting guide based on the received information.

[0175] In yet another embodiment, in order to overcome the limitation of the storage capacity of the processor 190 , the compression chip 150 may also directly generate the direction setting guide.

[0176] The processor 190 of the A / V transmitting device 100 may transmit the generated guide to the RF receiving interface 240 of the A / V receiving device 200 through the RF transmitting interface 160 (S515).

[0184] In this way, according to an embodiment of the present disclosure, even for a user who uses the wireless display system for the first time, an optimal wireless environment can be guided only by selecting an input of a direction set by the A / V transmission apparatus 100 .

[0185] On the other hand, according to still another embodiment of the present disclosure, even if the wireless quality status is a good status, a direction setting guide may be provided based on the usage information of the transmission antenna and the usage information of the reception antenna.

[0186] Figure 8 is a diagram illustrating an example of displaying a direction setting guide based on usage information of a transmitting antenna according to an embodiment of the present disclosure.

[0187] Figure 8 It can be Figure 5 The step S513 is concretized in the embodiment.

[0188] exist Figure 8 In the example, it is assumed that the wireless quality state between the A / V transmission device 100 and the A / V reception device 200 is in a good state.

[0189] The processor 190 of the A / V transmission device 100 may obtain identification information of one or more transmission antennas used for transmission of A / V data among the plurality of transmission antennas included in the RF transmission interface 160 .

[0190] The transmitting antenna used for the transmission of A / V data may be in an on state, and the transmitting antenna not used for the transmission of A / V data may be in an off state.

[0191] The processor 190 of the A / V transmission device 100 may obtain the number of enabled transmitting antennas according to the obtained identification information.

[0193] The processor 190 of the A / V transmission device 100 may generate a direction setting guide including the determined direction of the transmission antenna, and transmit the generated direction setting guide to the A / V reception device 200 .

[0194] Reference Figure 8 , the A / V receiving device 200 can display the received direction setting guide 800 on the display 260.

[0195] The direction setting guide 800 may include an operation image 810 and an operation text 830 for moving the direction of the transmitting antenna to the upper side by adjusting the slide button 401 a .

[0196] The direction setting guide 800 may also include information on the wireless quality status.

[0197] In this way, according to the embodiments of the present disclosure, since the wireless quality state is maintained in a good state and the number of transmitting antennas used is minimized, it is possible to provide an optimal wireless environment while reducing power consumption.

[0198] Fig. 9 This is a flowchart for explaining the operation method of the A / V receiving device according to one embodiment of the present disclosure.

[0199] Reference Fig. 9 , the microcomputer 290 of the A / V receiving device 200 may display a setting interface for selecting a setting direction of the A / V transmitting device 100 on the display 260 (S901).

[0200] Setting interface as Figure 6 shown.

[0201] The microcomputer 290 of the A / V receiving device 200 receives a direction selection input indicating the setting direction of the A / V transmitting device 100 (S903), and acquires information of the setting direction of the A / V transmitting device 100 selected according to the direction selection input (S905).

[0202] The microcomputer 290 may receive a direction selection input from the remote controller 300 .

[0203] The microcomputer 290 of the A / V receiving device 200 may acquire the wireless quality status between the A / V transmission device 100 and the A / V receiving device 200 (S907).

[0204] In one embodiment, the wireless quality status may indicate the strength of a signal received by the RF receiving interface 240 of the A / V receiving device 200 from the RF transmitting interface 160 .

[0205] The wireless quality status may include a plurality of quality statuses, which may include a good status, a normal status, a weak status, and a disconnected status.

[0206] The wireless quality status may be determined based on a received signal strength indicator (RSSI).

[0207] The microcomputer 290 or the recovery chip 280 of the A / V receiving device 200 may measure the RSSI of the wireless signal received by the RF receiving interface 240 from the RF transmitting interface 160 .

[0208] The microcomputer 290 or the recovery chip 280 of the A / V receiving device 200 may acquire the wireless quality status based on the measured RSSI.

[0209] The microcomputer 290 or the recovery chip 280 of the A / V receiving device 200 can judge that the wireless quality state is in a good state when the RSSI is in a first strength range, judge that the wireless quality state is in a normal state when the RSSI is in a second strength range smaller than the first strength range, and judge that the wireless quality state is in a weak state when the RSSI is in a third strength range smaller than the second strength range.

[0210] The microcomputer 290 or the recovery chip 280 of the A / V receiving device 200 may determine that the wireless quality state is a disconnected state (or a disconnected state) when RSSI is not received within a preset time.

[0211] The microcomputer 290 of the A / V receiving device 200 may determine whether the acquired wireless quality status is a preset quality status (S909), and if the acquired wireless quality status is determined to be a preset quality status, output the wireless quality status information to the display 260 (S911).

[0212] When the acquired wireless quality status is determined not to be a preset quality status, the microcomputer 290 of the A / V receiving device 200 generates a direction setting guide for adjusting the direction of one or more transmission antennas of the A / V transmitting device 100 (S913).

[0215] The microcomputer 290 of the A / V receiving device 200 may output the received direction setting guide to the display 260 (S915).

[0216] In this way, according to an embodiment of the present disclosure, even for a user who uses the wireless display system for the first time, an optimal wireless environment can be guided only by selecting an input of a direction in which the A / V transmission apparatus 100 is set.

[0217] Fig.10 It is a ladder diagram for explaining the operation method of the wireless display system according to still another embodiment of the present disclosure.

[0218] Fig.10 It can be in Figure 5 or Fig. 9 The scene that happened afterwards.

[0219] The processor 190 of the A / V transmission device 100 may acquire user log information (S1001).

[0220] The user log information may include one or more of sending log information or receiving log information.

[0221] The sending log information may include one or more of the setting direction of the A / V transmission device 100, the beam direction of the transmitting antenna, the number of transmitting antennas used (the number of ONs), the identification information of the transmitting antenna used, or the wireless quality value (for example, RSSI) measured between the A / V transmission device 100 and the A / V receiving device 200.

[0227] Processor 190 may be configured to Figure 5 and Fig. 9 In the subsequent process, user log information is generated and stored in the memory 140 .

[0228] When the initial setup and use of the wireless display system is completed, the processor 190 may store the user log information in the memory 140 .

[0229] The A / V transmission device 100 and the A / V reception device 200 may periodically share transmission log information and reception log information with each other.

[0230] The processor 190 of the A / V transmission device 100 may transmit the acquired user log information to the server 1000 through the wireless communication interface 120 ( S1003 ).

[0231] The processor 190 may transmit the user log information to the server 1000 through Internet communication.

[0232] The server 1000 may generate feedback information based on the user log information ( S1005 ), and transmit the generated feedback information to the A / V transmission device 100 ( S1007 ).

[0233] The server 1000 may analyze user log information and generate feedback information that may improve wireless performance.

[0234] The server 1000 may determine whether the wireless performance remains above a preset performance based on the user log information.

[0235] In one embodiment, the predetermined performance may be a predetermined ratio at which the compression rate of data is compressed.

[0236] In yet another embodiment, the preset performance may indicate a good state of the wireless quality state.

[0237] When the wireless performance is higher than a preset performance, the server 1000 may generate feedback information indicating that the wireless performance is good.

[0238] The feedback information may include information for adjusting the direction of a transmission antenna included in the RF transmission interface 160 .

[0239] The information for adjusting the direction of the transmitting antenna may include one or more of a tilt angle or a translation angle of the transmitting antenna.

[0240] The processor 190 of the A / V transmission device 100 may generate a direction adjustment guide for adjusting the direction of the transmission antenna of the RF transmission interface 160 based on the received feedback information (S1009).

[0241] The processor 190 may generate a direction adjustment guide based on information for adjusting the direction of the transmission antenna included in the feedback information.

[0242] The direction adjustment guide may be an image for guiding the adjustment direction of the transmitting antenna.

[0243] The processor 190 of the A / V transmitting device 100 may transmit the generated direction adjustment guide to the A / V receiving device 200 through the RF transmitting interface 160 (S1011).

[0244] The microcomputer 290 of the A / V receiving device 200 may output the received direction adjustment guide to the display 260 (S1013).

[0245] Fig.11a is an example of sending log information when the setting direction of the A / V transmission device is selected as the front direction, Fig.11b This is an example of reception log information in the case where the setting direction of the A / V transmission device is selected as the front direction.

[0246] Reference Fig.11a , shows transmission log information 1110. The transmission log information 1110 may include a number item 1111 of transmission antennas in use (two antennas in use), a direction item 1113 (or a transmission angle) of a beam transmitted by the used transmission antenna, and a compression rate item 1115.

[0247] Reference Fig.11b , shows reception log information 1130. The reception log information 1130 may include a number item 1131 of reception antennas in use (two are used) and a direction item 1133 (or reception angle) of a beam received by the used reception antennas.

[0248] The server 1000 may determine whether the used transmission antenna and reception antenna face each other through the direction of the beam included in the transmission log information 1110 and the direction of the beam included in the reception log information 1130 .

[0249] In addition, the server 1000 can determine through the compression rate item 1115 that the wireless performance is higher than the preset performance when the measured compression rate is higher than the preset rate (for example, 25).

[0250] When the transmitting antenna and the receiving antenna are facing each other (the transmitting beam and the receiving beam are in the same direction) and the compression rate is greater than a predetermined ratio, the server 1000 can generate feedback information indicating that there is no abnormality in the wireless performance, and transmit the generated feedback information to either the A / V transmitting device 100 or the A / V receiving device 200.

[0251] Fig.12a is another example of sending log information in the case where the setting direction of the A / V transmission device is selected as the left direction, Figure 12b This is another example of reception log information in the case where the setting direction of the A / V transmission device is selected as the left direction.

[0252] Reference Fig.12a , shows transmission log information 1210. The transmission log information 1210 may include a number of transmission antennas in use item 1211 (16 antennas in use), a direction item 1213 (or a transmission angle) of a beam transmitted by the used transmission antenna, and a compression rate item 1215.

[0253] Reference Figure 12b , shows reception log information 1230. The reception log information 1230 may include a number item 1231 of reception antennas in use (three are used) and a direction item 1233 (or reception angle) of a beam received by the reception antenna in use.

[0254] The server 1000 can determine that the transmission beam is facing the front through the direction of the beam included in the transmission log information 1210 , and can determine that the reception beam is facing the side through the direction of the beam included in the reception log information 1230 .

[0255] In addition, since the compression rate measured by the compression rate item 1215 is less than a preset ratio (for example, 25), the server 1000 can judge that the wireless performance is less than the preset performance.

[0256] That is, although the user selects the front direction as the installation direction of the A / V transmission device 100, the wireless performance is less than the preset performance due to the misalignment of the transmission antenna.

[0257] When the direction of the transmission beam is different from the direction of the reception beam and the compression rate is less than a preset ratio, the server 1000 may generate feedback information for adjusting the left-right or up-down direction of the transmission antenna. The server 1000 may transmit the generated feedback information to the A / V transmission device 100 or the A / V reception device 200.

[0258] The A / V receiving apparatus 200 may display a direction adjustment guide based on the feedback information on the display 260 .

[0259] Thus, according to the embodiments of the present disclosure, an active installation environment can be guided by utilizing user log information according to the installation environment, and guidance can be provided in real time by interactively approaching the user. Thus, a wireless installation environment for the user can be easily and conveniently provided.

[0260] In addition, even if the user moves the location of the A / V transmission device 100 or changes the wireless installation environment, since the optimization guide is provided through the network, there is an advantage that the user can easily adjust the antenna.

[0261] Fig.13ais a diagram illustrating an example of providing a direction adjustment guide by feedback information generated based on user log information, Fig.13b is a diagram illustrating an example of a reset guide for resetting a setting direction of an A / V transmission device by feedback information generated based on user log information.

[0262] Reference Fig.13a , the server 1000 can generate feedback information based on the user log information and transmit the generated feedback information to the A / V transmission device 100.

[0263] The A / V transmission device 100 may generate a guide image for adjusting the direction of the transmission antenna based on the received feedback information, and transmit the generated guide image to the A / V reception device 200 .

[0264] The A / V receiving device 200 may display the received guide image 1310 on the display 260. The guide image 1310 may include an operation image 1311 and an operation text 1313 that guide the operation of a slide button or a dial.

[0265] The user may set an optimal wireless environment through the guide image 1310 .

[0266] Reference Fig.13b , the server 1000 can generate feedback information based on the user log information and transmit the generated feedback information to the A / V transmission device 100.

[0267] When it is determined based on the user log information that the initial setting direction of the A / V transmission device 100 is the front and the measured wireless performance is less than the preset performance, the server 1000 may generate feedback information for resetting the setting direction of the A / V transmission device 100 .

[0268] Even if the wireless quality state is in a good state, when the number of transmission antennas in use is greater than a predetermined number, the server 1000 may determine that the wireless performance is lower than a preset performance.

[0269] The A / V transmission device 100 may generate a reset guide image for resetting the setting direction of the A / V transmission device 100 based on the feedback information received from the server 1000 , and transmit the generated reset guide image to the A / V receiving device 200 .

[0270] The A / V receiving device 200 may display the received reset guide image 1330 on the display 260. The reset guide image 1330 may include a reset image 1331 for setting a setting direction of the A / V transmitting device 100 and a reset text 1333.

[0271] The user may readjust the setting direction of the A / V transmission apparatus 100 by resetting the guide image 1330 , thereby setting an optimal wireless environment.

[0272] On the other hand, according to another embodiment of the present disclosure, when the directions of the transmitting beam and the receiving beam are the same and the number of transmitting antennas used within a predetermined time period changes more than a predetermined number of times, the server 1000 can generate feedback information indicating the presence of an obstacle based on user log information, and transmit the generated feedback information to the A / V transmission device 100 or the A / V receiving device 200.

[0273] The A / V receiving device 200 may not display a guide for adjusting the direction of the transmission antenna according to the feedback information indicating the presence of an obstacle.

[0274] In this way, according to an embodiment of the present disclosure, an obstacle existing between the A / V transmission device 100 and the A / V reception device 200 can also be detected, thereby preventing unnecessary guides from being displayed.

[0275] According to an embodiment of the present disclosure, the above method can be implemented by a processor-readable code in a medium storing a program. Computer-readable media include, for example, ROM, RAM, CD-ROM, magnetic disk, floppy disk, and optical data storage device.

[0276] The A / V transmission device 100 or the A / V receiving device 200 described above is not limited to the configuration and method of the described embodiments, and all or part of the embodiments may also be selectively combined and configured to enable the embodiments to achieve various variations.
