All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It is to be noted that the terms "comprises" and "comprising" and any variations thereof in the embodiments and drawings of the present invention are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.
The embodiment of the invention discloses a video communication method and wearable equipment, which can reduce power consumption during video output and reduce heat generation of the wearable equipment. The following are detailed below.
Example one
Referring to fig. 1, fig. 1 is a flowchart illustrating a video communication method according to an embodiment of the present invention. The video communication method described in fig. 1 is suitable for wearable devices such as smartwatches, smartbands, and smartglasses, and the embodiment of the present invention is not limited thereto. The operating system of the wearable device may include, but is not limited to, an Android operating system, an IOS operating system, a Symbian operating system, a Black Berry operating system, a Windows Phone8 operating system, and the like. As shown in fig. 1, the video communication method may include the steps of:
101. the wearable device detects a transmission environment parameter at the time of its current video data transmission.
In the embodiment of the present invention, the transmission environment parameter may include a wireless signal parameter and/or a parameter that may affect the wearable device to transmit video data, such as an operating temperature of the wearable device.
The wireless signal parameter may be determined according to a current data transmission state quantity of the wearable device, and the data transmission state quantity may include a current network system, a network frequency band, a signal strength, and the like. In addition, the network format used by the wearable device in transmitting video data may include 3rd-Generation (3G), 4th-Generation (4G), 5th-Generation (5G), Wi-Fi, etc.; the network frequency band used by the wearable device when transmitting the video data can be a frequency band suitable for any one of the network systems; the Signal Strength may be determined by detecting a Received Signal Strength Indication (RSSI) of the wearable device. The operating temperature of the wearable device may specifically be a temperature of a Central Processing Unit (CPU) of the wearable device when transmitting the video data.
102. The wearable device adjusts the video format parameters according to the detected transmission environment parameters.
In the embodiment of the present invention, the video format parameters may include parameters for representing video quality, such as a video frame rate and a video code rate. The video frame rate is a measurement for measuring the display frame number, and is related to the fluency of video pictures, and the higher the frame rate is, the more fluency the video pictures are; the video code rate refers to the number of data bits that can be transmitted in unit time during video data transmission, and is related to the definition of a video picture, and the higher the code rate is, the clearer the video picture is. As an optional implementation manner, in the embodiment of the present invention, the video format parameter may be positively correlated with the transmission environment parameter, that is, the transmission environment parameter indicates that the more the current transmission environment is favorable for video data transmission, the higher the video quality represented by the video format parameter corresponding to the transmission environment parameter is. In particular, the video format parameters characterize higher video quality if the wireless signal parameters indicate higher wireless signal quality and/or higher operating temperature of the wearable device.
In addition, as an optional implementation manner, the wearable device may determine the corresponding video format parameter according to the transmission environment parameter by:
pre-dividing transmission environment grades indicated by transmission environment parameters and video quality grades represented by video format parameters, wherein one transmission environment grade corresponds to one video quality grade, the values of the transmission environment parameters corresponding to the transmission environment grades are different, and the values of the video format parameters corresponding to the video quality grades are different;
when the wearable device detects the transmission environment parameters, identifying a target transmission environment grade to which the detected transmission environment parameters belong, and determining a target video quality grade corresponding to the target transmission environment grade;
the wearable device determines a video format parameter corresponding to the target video quality level as a video format parameter corresponding to the detected transmission environment parameter;
wherein, the transmission environment level is positively correlated with the video quality level.
103. And the wearable equipment transmits the video data to be transmitted according to the adjusted video format parameters.
In the embodiment of the invention, because the data volume of the video data is large, the calculation amount of the wearable device is large when the video data is transmitted, and the power required by the wearable device when the video data is transmitted is large, so that the wearable device is easy to heat up and generate heat when in video call, and the power consumption is serious. In the embodiment of the invention, the wearable device transmits the video data to be transmitted according to the adjusted video format parameters, so that the video format parameters can be dynamically adjusted according to different environment transmission parameters, the quality of the video image to be transmitted is adjusted, the power consumption of the wearable device can reach a dynamic balance state, and the heating of the wearable device is reduced.
It can be seen that, in the method described in fig. 1, the wearable device may automatically detect the transmission environment parameter, and adjust the video format parameter according to the transmission environment parameter, so as to adjust the quality of the video image to be transmitted, so that the power consumption of the wearable device may reach a dynamic balance state, and further reduce the heat generation of the wearable device.
Example two
Referring to fig. 1, fig. 1 is a flowchart illustrating a video communication method according to an embodiment of the present invention. In the method described in fig. 1, the wearable device performs step 101 to detect the transmission environment parameter of its current video data transmission, and the transmission environment parameter detected by the wearable device may include the following cases: the wearable device detects wireless signal parameters; the wearable device detects the working temperature of the wearable device; the wearable device detects the wireless signal parameter and its operating temperature. The following describes the video communication method in each case separately.
Referring to fig. 2, fig. 2 is a flow chart illustrating another video communication method according to an embodiment of the invention. In the method shown in fig. 2, the transmission environment parameter detected by the wearable device is a wireless signal parameter, and the method shown in fig. 2 includes the following steps:
201. the wearable device detects wireless signal parameters at the time of its current video data transmission.
In the embodiment of the invention, the wearable device can detect the wireless signal parameters according to a certain detection frequency. Taking wearable equipment using an Android operating system as an example, a timer can be set in the system by calling an ril (radio Interface layer), and wireless signal parameter information provided by a baseband chip plus Coprocessor (CP) is read at regular time.
202. And the wearable equipment determines the current signal quality according to the signal intensity, the network type and the network frequency band included in the wireless signal parameters.
In the embodiment of the invention, the current signal quality can be obtained by weighting calculation according to the signal intensity, the network type, the network frequency band and the like. As an optional implementation manner, in this embodiment of the present invention, before performing step 203, the wearable device may further determine, according to the detected signal strength, whether the wearable device is currently in a weak signal area (for example, the detected RSSI value is lower than a specified threshold, and then the wearable device is considered to be in the weak signal area); if the wearable device is in the weak signal area, determining whether the current network frequency band is in a preset specific frequency band (when the network frequency band is in the specific frequency band, the power required by the wearable device to transmit data is higher than a specified threshold), and when the wearable device is in the weak signal area and the current network frequency band is in the specific frequency band, the wearable device triggers and executes step 203. By implementing the implementation manner, the wearable device can judge whether the current transmission environment is not beneficial to the transmission of the video data according to the wireless signal parameters, and adjust the video format parameters when judging that the transmission environment is not beneficial to the transmission of the video data, so that the frequency of adjusting the video format parameters can be reduced, the conversion speed of the video image quality is reduced, and the user experience is improved.
203. The wearable device determines a first video format parameter corresponding to the current signal quality according to the corresponding relation between the signal quality and the video format parameter.
In the embodiment of the present invention, the correspondence between the signal quality and the video format parameter includes: as the signal quality degrades, the video quality characterized by the video format parameters degrades. For example, the wearable device may divide the signal quality into three steps 1, 2, and 3, with a larger number indicating a worse signal quality; in addition, the video image quality corresponding to the video format parameter can also be divided into A, B, C three grades, and the video image quality is decreased sequentially. As the signal quality decreases, the video quality represented by the video format parameters decreases, and the signal quality levels correspond to the video image quality levels one to one. Assuming that the current signal quality is identified as 1 grade, the first video format parameter is a video format parameter corresponding to the A grade image quality; assuming that the current signal quality is identified as 3rd, the first video format parameter is a video format parameter corresponding to the C-range image quality.
204. The wearable device determines the first video format parameter as an adjusted video format parameter.
205. And the wearable equipment transmits the video data to be transmitted according to the adjusted video format parameters.
It can be seen that in the method shown in fig. 2, the wearable device can determine the current network environment according to the wireless signal quality when the wearable device transmits video data. Because the power consumption required by the wearable device for transmitting the video data is larger when the network environment is poor, the wearable device can reduce the video format parameters when transmitting the video data when detecting that the network environment is poor, thereby reducing the power consumption of the wearable device and reducing the heating and power consumption.
Referring to fig. 3, fig. 3 is a flow chart illustrating another video communication method according to an embodiment of the disclosure. In the method shown in fig. 3, the transmission environment parameter detected by the wearable device is the operating temperature of the wearable device, and the method shown in fig. 3 includes the following steps:
301. the wearable device detects an operating temperature of the wearable device when its current video data is transmitted.
In the embodiment of the invention, the working temperature of the wearable device can be the temperature of the CPU of the wearable device, and the wearable device can read the temperature of the CPU according to a certain frequency and monitor the temperature of the CPU in real time. As an optional implementation manner, before performing step 302, the wearable device may further determine whether the detected operating temperature exceeds a specified operating temperature threshold, if so, the wearable device performs step 302, and if not, the wearable device continues to transmit the video data to be transmitted according to the current video format parameter, and does not adjust the video format parameter.
302. The wearable device obtains the current ambient temperature at which the wearable device is located, and determines a current temperature difference between the operating temperature and the current ambient temperature.
In the embodiment of the invention, the wearable device can inquire the temperature of the location of the wearable device through the network interface as the current environment temperature of the wearable device; optionally, the wearable device may also obtain an ambient temperature detected by the temperature sensor of the wearable device as a current ambient temperature of the wearable device, which is not limited in the embodiment of the present invention.
303. And the wearable equipment determines a second video format parameter corresponding to the current temperature difference value according to the corresponding relation between the temperature difference value and the video format parameter.
In the embodiment of the present invention, the correspondence between the temperature difference and the video format parameter includes: as the temperature difference decreases, the quality of the video characterized by the video format parameters decreases. As an alternative embodiment, the wearable device may set the correspondence between the temperature difference value and the video format parameter using the specified operating temperature threshold and the specified ambient temperature threshold as the reference. For example, assuming that the operating temperature threshold is 48 ℃ and the ambient temperature threshold is 26 ℃, the quality of the video image of the video data to be transmitted can be divided into A, B, C three grades, and the quality of the video image is decreased sequentially. The corresponding relation between the temperature difference and the video format parameters can set the video format parameters corresponding to the temperature difference when the working temperature of the wearable device is lower than 48 ℃ as the video format parameters corresponding to the A-grade image quality; when the working temperature of the wearable device is higher than 48 ℃ and the current environment temperature is lower than 26 ℃, the video format parameter corresponding to the temperature difference value is a video format parameter corresponding to the B-grade image quality; the video format parameter corresponding to the temperature difference value when the working temperature of the wearable device is higher than 48 ℃ and the current environment temperature is higher than 26 ℃ is the video format parameter corresponding to the C-gear image quality. That is, the first temperature difference value when the working temperature is higher than 48 ℃ and the current environment temperature is lower than 26 ℃ is greater than the second temperature difference value when the working temperature is higher than 48 ℃ and the current environment temperature is higher than 26 ℃, so that the video image quality corresponding to the first temperature difference value is higher than the video image quality corresponding to the second temperature difference value.
304. The wearable device determines the second video format parameter as the adjusted video format parameter.
305. And the wearable equipment transmits the video data to be transmitted according to the adjusted video format parameters.
It can be seen that, in the method described in fig. 3, the wearable device may adjust the video image quality during video data transmission in real time according to the working temperature thereof, and further, a temperature difference between the working temperature of the wearable device and the current ambient temperature may be considered, when the temperature difference is smaller, the heat dissipation is slower, the video image quality is reduced, and when the temperature difference is larger, the heat dissipation is faster, the higher video image quality is adopted, so that the video image quality of the wearable device may be adjusted in consideration of the heat dissipation of the wearable device.
Referring to fig. 4, fig. 4 is a flowchart illustrating another video communication method according to an embodiment of the present invention. In the method shown in fig. 4, the transmission environment parameters detected by the wearable device are the wireless signal parameters and the operating temperature of the wearable device, and the method shown in fig. 4 includes the following steps:
401. the wearable device detects wireless signal parameters of the wearable device when the wearable device transmits current video data and the operating temperature of the wearable device.
402. The wearable device determines the current signal quality according to the signal strength, the network type and the network frequency band which are included in the wireless signal parameters, and determines a first video format parameter corresponding to the current signal quality according to the corresponding relation between the signal quality and the video format parameter.
In the embodiment of the present invention, the correspondence between the signal quality and the video format parameter includes: as the signal quality degrades, the video quality characterized by the video format parameters degrades.
403. And the wearable equipment determines a second video format parameter corresponding to the current temperature difference value according to the current temperature difference value between the working temperature and the current environment temperature of the wearable equipment and the corresponding relation between the temperature difference value and the video format parameter.
In the embodiment of the present invention, the correspondence between the temperature difference and the video format parameter includes: as the temperature difference decreases, the quality of the video characterized by the video format parameters decreases.
404. The wearable device determines whether the video quality characterized by the first video format parameter is lower than the video quality characterized by the second video format parameter, if so, step 405 is executed, and if not, step 406 is executed.
405. The wearable device determines the first video format parameter as an adjusted video format parameter.
406. The wearable device determines the second video format parameter as the adjusted video format parameter.
In the embodiment of the invention, the wearable device determines a first video format parameter according to the wireless signal parameter, determines a second video format parameter according to the temperature difference between the working temperature and the ambient temperature, and selects the parameter with poor video quality represented by the first video format parameter and the second video format parameter as the adjusted video format parameter, so that the network environment and the temperature can be comprehensively considered, and the final video image quality can be determined.
407. And the wearable equipment transmits the video data to be transmitted according to the adjusted video format parameters.
Therefore, in the method described in fig. 4, the wearable device can detect the wireless signal intensity, the working temperature of the wearable device, and the ambient temperature, respectively, so that the network environment and the temperature can be considered comprehensively to determine the final video image quality, and the heat generated by the wearable device in the video call process can be reduced to the maximum extent.
