Example 1
Referring to fig. 1, fig. 1 is a schematic flow chart of a wired screen-throwing control method according to an embodiment of the present invention. The embodiment of the invention provides a wired screen-throwing control method, which comprises the following steps of 101-104:
step 101: starting a first terminal and detecting whether a dynamic detection target exists in a preset range;
step 102: when a dynamic detection target exists in the preset range, controlling the first terminal to start display equipment, and sending a preset sound source to the display equipment; the first terminal is connected with the display device through an HDIM data line;
step 103: collecting sound source data played by the display equipment in real time;
step 104: and when the sound source data is consistent with the preset sound source, determining that the first terminal and the display equipment establish a screen-throwing connection relation.
The first terminal is a computing machine capable of directly sending out a control command, and includes, but is not limited to, a computer, a mobile phone, a tablet, a panel, a touch screen and other server devices, and the display device is a device capable of outputting images or touch information (such as a braille display designed for the blind person), such as a home IPTV, and also an office IPTV, such as a flight meeting, a flying book and the like. Preferably, in the embodiment of the present invention, the first terminal is a set top box, and the display device is a television.
In an embodiment, the detecting whether the dynamic detection target exists in the preset range specifically includes: according to the first detection strategy and the second detection strategy, dynamic target detection is carried out in a preset range at the same time; when the first detection strategy and the second detection strategy simultaneously judge that a dynamic detection target exists in a preset range, determining that the dynamic detection target exists in the preset range; and when only one detection strategy judges that the dynamic detection target exists in the preset range, carrying out dynamic target detection again after a preset time interval, and if at least one detection strategy judges that the dynamic detection target exists in the preset range, determining that the dynamic detection target exists in the preset range. In the embodiment of the invention, two detection strategies are adopted to detect the dynamic target simultaneously, and the dynamic detection target in the preset range of the first terminal is determined only when the two detection strategies simultaneously judge that the dynamic detection target exists in the preset range. If only one detection target judges that the dynamic detection target exists, the dynamic target detection is carried out again after a preset time interval, and when at least one detection strategy judges that the dynamic detection target exists, the dynamic detection target exists in a preset range, so that the situation that the judgment result is inconsistent when one detection strategy has a fault or the two detection strategies are not synchronous can be avoided, and the accuracy and the strictness of the dynamic target detection are improved.
In one embodiment, the first detection policy specifically includes: setting a sensing device on the first terminal; acquiring reference data of the sensing device; when the switching of the reference data of the sensing device is detected, the dynamic detection target is judged to exist in a preset range. An infrared sensor or a radar sensor is arranged on the set top box, and whether a dynamic detection target exists in a preset range is judged through the transformation of the sensor. Preferably, in the embodiment of the present invention, a radar sensor is disposed on the set-top box, and a detection direction of the radar sensor faces the television, and a human body movement is used as a dynamic detection target. Initializing a detection pin of the radar sensor, wherein the detection pin of the radar sensor is at a high level, triggering the detection pin level of the radar sensor to be pulled down when a dynamic detection target exists, and switching the pin level of the radar sensor at the moment, so that the existence of the dynamic sensor in a preset range is judged. Further, the preset range of dynamic target detection can be determined according to the detection range of the sensor, and is typically 8 to 16 meters.
In one embodiment, the second detection policy specifically includes: collecting sound data in a preset range in real time; and detecting voice activity of the voice data according to a preset algorithm, and judging that the dynamic detection target exists in a preset range when the voice data contains human voice. And (3) setting MIC equipment on the set top box, and collecting sound data in a preset range of the set top box in real time. And voice activity detection is carried out on the collected voice data by adopting a VAD algorithm, and whether voice exists in the voice data is judged. The VAD algorithm divides the frequency spectrum of sound data into six sub-bands (80 Hz-250Hz,250Hz-500Hz,500Hz-1K,1K-2K,2K-3K, 3K-4K.) according to the frequency spectrum range of human voice, and calculates the energy of the six sub-bands respectively. And then, carrying out operation by using a probability density function of the Gaussian model to obtain a log-likelihood ratio function. The log-likelihood ratio is divided into global and local, global being a weighted sum of six subbands and local referring to each subband. The voice judgment can firstly judge the sub-band, the sub-band judgment can not judge the global state, and if one party passes the judgment, the voice data is judged to have human voice, namely, a dynamic detection target of human body movement exists.
As a preferable scheme of the embodiment of the invention, when receiving an operation screen-throwing instruction sent by a user side, the display equipment is directly started, the screen-throwing connection relation between the first terminal and the display equipment is established, and dynamic target detection is closed. Referring to fig. 2, fig. 2 is a schematic flow chart of dynamic object detection according to an embodiment of the present invention. When the dynamic detection target exists, the calibration is 1, and if the dynamic detection target does not exist, the calibration is 0. The first detection strategy is used as radar judgment, and the second detection strategy is used as VAD judgment. Under scene 1, when the radar judgment and the VAD judgment are both calibrated to be 1, determining that a dynamic detection target exists in a preset range, starting the television, and closing the dynamic target detection. Scene 2 and scene 3 are the situation that any detection strategy is calibrated to be 1, at this time, the dynamic target detection is restarted after 2 seconds, if the judgment of one detection strategy is still 1, the dynamic detection target exists in the preset range, the television is started, and the dynamic target detection is closed. In scene 4, if both detection strategies are determined to be 0, then no dynamic detection target exists in the preset range, the television is not started at this time, and the dynamic target detection is continuously started in the preset range. In the scenes 5-8, no matter whether the detection strategy is judged to be 1 or not, if only a screen-throwing instruction of operation sent by a user is received, the television is started immediately, the screen-throwing connection relation between the set top box and the television is established, and dynamic target detection is closed. In an embodiment, the wired screen-throwing control method further includes controlling the first terminal to obtain an instruction for starting the display device, specifically: controlling the first terminal to perform infrared learning; receiving all infrared remote control signals transmitted by a controller of the display equipment and storing the signals to the first terminal; and carrying out logic analysis on the infrared remote control signals to obtain the function instruction mapped by each infrared remote control signal. In order to enable the set top box to be compatible with television interaction functions of various brands, the embodiment of the invention further comprises a circuit module which is integrated by an infrared receiving circuit and an infrared transmitting circuit and is arranged in the set top box, so that the set top box is ensured to have an infrared learning function. Because the infrared receiving circuit and the infrared transmitting circuit are common technical structures in the prior art, the circuit structure is not repeated here. When the set top box is in infrared learning, any infrared remote control signal emitted by the controller of the television, namely the remote controller, is received by the set top box and stored in the set top box within the infrared receiving range of the set top box. The received infrared remote control signal is logically analyzed, and preferably, the embodiment of the invention adopts a Kingst digital signal logic analyzer to logically analyze the infrared remote control signal so as to obtain the functional instruction mapped by the infrared remote control signal. Based on the above, after the set top box finishes the infrared learning of the remote controller corresponding to the television, the set top box has the function of remote control/starting of the television.
In an embodiment, after the display device is started, the set-top box sends a section of preset sound source to the television through an HDMI data line connected with the television, and the MIC device is installed on the set-top box to collect the sound source data played by the display device at the moment. The VAD sound detection can also be used for identifying the use scene of the guide sound source, preferably, the VAD algorithm is used for judging whether the play sound source of the television set is consistent with the sent preset sound source at the moment, if so, the television set is successfully started, the television set outputs the designated sound source transmitted by the set top box through the loudspeaker, and the set top box and the television set establish a screen connection relation at the moment. If the preset sound source cannot be identified in the collected sound source data, the preset sound source sent by the set top box cannot be normally transmitted to the television set, the television set is used for playing, at the moment, the television is failed to start, and the screen connection relation is not established between the set top box and the television set.
As a preferred scheme of the embodiment of the present invention, after the first terminal is started, the level signal of the HDIM data line is detected in real time; and when the level signal is converted, judging that the display equipment is successfully started, and establishing a screen-throwing connection relation between the first terminal and the display equipment. The set top box is connected with the television through the HDMI data line, the power supply pins of the HDMI data pins are detected, when the television is successfully started, the power supply pins of the HDMI data line are switched to a high level, the set top box can transmit data such as audio and video to the television, therefore, when the level signal of the HDMI data line is detected to be switched to the high level, the television can be judged to be successfully started, and the set top box and the television establish a screen connection relation. In some specific application scenarios, when the CEC protocol exists in the HDMI communication, if the television is turned on successfully, the corresponding bus will be pulled up to +3.3v, and at this time, whether the television is turned on successfully can be determined directly by detecting whether the bus (open collector line) has level switching.
