Detailed Description

Referring to fig. 1, an information transmission method in an embodiment of the present invention may be applied to a first electronic device. The method mainly comprises the following steps:

step 101: when first frame image information needs to be transmitted, the first frame image information is compared with at least one frame image information transmitted previously according to a preset priority level, and a comparison result is generated.

When the first frame of image information needs to be transmitted, the first frame of image information and at least one frame of image information transmitted before can be respectively compared according to a preset priority.

In the embodiment of the present invention, the first frame of image information may be compared with the previous mth frame of image information transmitted before according to a preset priority, where M is a positive integer; or, the first frame image information and the previous L frame image information transmitted before may be respectively compared according to a preset priority.

In the embodiment of the present invention, before comparing the first frame of image information with at least one frame of image information transmitted before according to the preset priority, the region included in one frame of image information may be divided into at least two priorities according to the importance degree, and then the region included in the first frame of image information and the corresponding region in the at least one frame of image information transmitted before are sequentially compared according to the order from high to low of the priorities.

Preferably, in the embodiment of the present invention, the area included in the image information of one frame may be divided into four priority levels according to the degree of importance. In image transmission during application such as video call, people's change in video is a concern, so in one frame of image information, people's priority is higher than that of background environment. In the present embodiment, the facial expressions of the human may be preset to a first priority, the regions of the human face other than the facial expressions of the human may be preset to a second priority, the limbs of the human may be preset to a third priority, and the background environment may be preset to a fourth priority. Wherein the first priority has the highest importance level and the fourth priority has the lowest importance level.

In the embodiment of the present invention, the step of comparing the first frame of image information with at least one frame of image transmitted before according to the preset priority may specifically be as follows. Or other embodiments of the step are possible, and the invention is not limited to:

comparing the first image information contained in a first area corresponding to a first priority in the first frame of image information with corresponding image information contained in the at least one frame of image information respectively, and judging whether the first image information and the corresponding image information are consistent; when the first frame of image information and the second frame of image information are judged to be consistent, continuously comparing the first image information contained in a second area corresponding to a second priority in the first frame of image information with corresponding image information contained in the at least one frame of image information respectively; and when the two are judged to be inconsistent, generating the comparison result.

Namely: firstly, comparing the first image information contained in a first area corresponding to the first priority in the first frame of image information with corresponding image information contained in the at least one frame of image information respectively, judging whether the first image information and the corresponding image information are consistent, if the first image information and the corresponding image information are judged to be consistent, continuously comparing the first image information contained in a second area corresponding to the second priority in the first frame of image information with corresponding image information contained in the at least one frame of image information respectively, if the first image information and the corresponding image information are judged to be consistent, continuously comparing the first image information contained in a third area corresponding to the third priority in the first frame of image information with corresponding image information contained in the at least one frame of image information, and comparing in sequence until the comparison result is judged to be inconsistent under a certain priority, the comparison result may be generated, and the comparison result may be used to indicate that the first image information included in the first frame of image information is inconsistent with the corresponding image information included in the at least one frame of image information at a certain priority. Or, if all the priorities are compared, it is determined that the first image information included in the first frame of image information at each priority is consistent with the corresponding image information included in the at least one frame of image information, and the comparison result may also be generated, where the comparison result may be used to indicate that the first image information included in the first frame of image information at each priority is consistent with the corresponding image information included in the at least one frame of image information.

Second, the first image information included in each region corresponding to each priority in the first frame of image information and the corresponding image information included in the at least one frame of image information may be respectively compared to generate the comparison result. That is, the first image information included in the first region corresponding to the first priority in the first frame of image information and the corresponding image information included in the at least one frame of image information may be compared, respectively, to determine whether the first image information and the corresponding image information are consistent, the determination result may be recorded, whether the first image information included in the second region corresponding to the second priority in the first frame of image information and the corresponding image information included in the at least one frame of image information are consistent or not may be determined, respectively, to determine whether the first image information and the corresponding image information are consistent or not may be recorded, and whether the first image information included in the third region corresponding to the third priority in the first frame of image information and the corresponding image information included in the at least one frame of image information are consistent or not may be determined, judging whether the first frame image information and the second frame image information are consistent, recording a judgment result, and continuously comparing the first image information contained in a fourth area corresponding to a fourth priority in the first frame image information with the corresponding image information contained in the at least one frame image information no matter whether the first frame image information and the second frame image information are consistent is judged and determined, and after the comparison is finished in sequence, generating a comparison result which can be used for indicating whether the first image information contained in the first frame image information is consistent with the corresponding image information contained in the at least one frame image information under each priority.

First, if the first frame image information is compared with the previous mth frame image information transmitted before according to the preset priority, the situation may be as described above. Wherein can be selected from

If the first frame image information is compared with the previous L frame image information transmitted before according to the preset priority, the following conditions may be adopted:

for example, if L is 3, it is assumed that the first frame image information is compared with the previously transmitted previous second frame image information, previous fourth frame image information, and previous fifth frame image information.

For example, when comparing the first frame image information with the second frame image information, the comparison method may be the first comparison method as described above, that is: firstly, comparing the first image information contained in a first area corresponding to the first priority in the first frame of image information with the corresponding image information contained in the previous second frame of image information, judging whether the first image information and the previous second frame of image information are consistent, if the first image information and the previous second frame of image information are consistent, continuously comparing the first image information contained in a second area corresponding to the second priority in the first frame of image information with the corresponding image information contained in the previous second frame of image information, if the first image information and the previous second frame of image information are consistent, continuously comparing the first image information contained in a third area corresponding to the third priority in the first frame of image information with the corresponding image information contained in the previous second frame of image information, and comparing in sequence until the comparison result is determined to be inconsistent under a certain priority, the comparison result may be generated, and the comparison result may be used to indicate that the first image information included in the first frame image information is inconsistent with the corresponding image information included in the previous second frame image information at a certain priority. Or, if all the priorities are compared, it is determined that the first image information included in the first frame image information is consistent with the corresponding image information included in the previous second frame image information at each priority, and the comparison result may also be generated, where the comparison result may be used to indicate that the first image information included in the first frame image information is consistent with the corresponding image information included in the previous second frame image information at each priority.

In this embodiment, a comparison result of comparing the first frame image information with the previous second frame image information may be that the first image information of a second region corresponding to a second priority in the first frame image information is changed.

In this embodiment, when comparing the first frame image information with the previous second frame image information, the comparison method adopted may also be the first comparison method, and in this embodiment, the comparison result of comparing the first frame image information with the previous fourth frame image information may be that the first image information of the first area corresponding to the first priority in the first frame image information is changed.

In this embodiment, when comparing the first frame image information with the fifth frame image information, the comparison method adopted may be the second comparison method as above, that is: the first image information included in each region corresponding to each priority in the first frame of image information and the corresponding image information included in the previous fifth frame of image information may be respectively compared to generate the comparison result. That is, the first image information included in the first region corresponding to the first priority in the first frame of image information may be compared with the corresponding image information included in the previous fifth frame of image information, whether the first image information and the previous fifth frame of image information are consistent or not may be determined, the determination result may be recorded, whether the first image information included in the second region corresponding to the second priority in the first frame of image information is consistent or not may be determined, whether the first image information and the previous fifth frame of image information are consistent or not may be determined, the determination result may be recorded, and whether the first image information included in the third region corresponding to the third priority in the first frame of image information is consistent or not may be determined, the first image information included in the third region corresponding to the third priority in the first frame of image information and the previous fifth frame of image information may be continuously compared, judging whether the first frame image information and the second frame image information are consistent, recording a judgment result, and continuously comparing the first image information contained in a fourth area corresponding to a fourth priority in the first frame image information with corresponding image information contained in the previous fifth frame image information no matter whether the first frame image information and the second frame image information are consistent is judged and determined, so that after the comparison is completed in sequence, the comparison result can be generated, and the comparison result can be used for indicating whether the first image information contained in the first frame image information is consistent with the corresponding image information contained in the previous fifth frame image information under each priority.

In this embodiment, a comparison result of comparing the first frame image information with the previous fifth frame image information may be that the first image information of a third area corresponding to a third priority in the first frame image information and the first image information of a fourth area corresponding to a fourth priority in the first frame image information are both changed, and the first image information of a first area corresponding to a first priority in the first frame image information and the first image information of a second area corresponding to a second priority in the first frame image information are not changed.

In this embodiment, when the first frame image information is compared with the second frame image information, the fourth frame image information, and the fifth frame image information, respectively, the obtained comparison results are different, and the content to be transmitted can be selected according to the comparison results and the priority.

For example, in this embodiment, the comparison result indicates that the content of the area corresponding to the four priorities in the first frame of image information is changed, when transmitting, only the first image information corresponding to the first priority in the first frame of image information may be transmitted, or when transmitting, the first image information corresponding to the first priority in the first frame of image information and the first image information corresponding to the second priority in the first frame of image information may also be transmitted, or when transmitting, the first image information corresponding to the first priority in the first frame of image information, the first image information corresponding to the second priority in the first frame of image information, and the first image information corresponding to the third priority in the first frame of image information may also be transmitted, or when transmitting, the first image information corresponding to the first priority in the first frame of image information may also be transmitted First image information, the first image information corresponding to the second priority in the first frame image information, the first image information corresponding to the third priority in the first frame image information, and the first image information corresponding to the fourth priority in the first frame image information are transmitted. The specific transmission conditions can be set as required.

Or, if a comparison result obtained when comparing the first frame image information with the previous second frame image information is: the first image information in the first region corresponding to the first priority in the first frame image information is changed, and a comparison result obtained when comparing the first frame image information with the previous fourth frame image information is as follows: the first image information in the second region corresponding to the second priority in the first frame image information is changed, and a comparison result obtained when comparing the first frame image information with the previous fourth frame image information is as follows: the first image information in the second area corresponding to the second priority in the first frame image information is changed. According to a general selection rule, since both comparison results indicate that the first image information corresponding to the second priority in the first frame image information is changed, only the first image information in the second area corresponding to the second priority in the first frame image information may be transmitted, but one comparison result also indicates that the first image information in the first area corresponding to the first priority in the first frame image information is changed, and the first priority corresponds to five sense organs of a human being, which are the most concerned content in a video call, so that in order to obtain better video call quality, the first image information in the first area corresponding to the first priority in the first frame image information and the first image information in the second area corresponding to the second priority in the first frame image information may be transmitted together during transmission And (6) inputting. For example, in this case, if two comparison results indicate that the first image information in the second area corresponding to the second priority in the first frame of image information has changed, and one comparison result indicates that the first image information in the third area corresponding to the third priority in the first frame of image information has changed, only the first image information in the second area corresponding to the second priority may be transmitted during transmission.

In this embodiment of the present invention, before performing step 101, the first electronic device may also be controlled to enter the first mode. In this embodiment of the present invention, the first mode may refer to an energy saving mode, and specifically may be a working mode used when the network quality is not good.

In the embodiment of the present invention, the current network quality may be determined according to the current network quality value, and if the determination result indicates that the current network quality value is smaller than the preset network quality threshold, it may be determined that the current network quality is not good, and the first electronic device may be controlled to enter the first mode. The steps shown in fig. 1 are all completed by the first electronic device in the first mode.

Step 102: and generating a first transmission instruction when the comparison result shows that the first image information contained in the first frame of image information is inconsistent with the corresponding image information contained in the at least one frame of image information.

In this embodiment of the present invention, the first transmission instruction may be used to indicate that the first image information is transmitted, and the first image information may correspond to one priority, or the first image information may also correspond to a plurality of priorities.

In the embodiment of the present invention, only a changed portion of one frame of image may be transmitted, if a person is kept still during a video call, a comparison result may be that there is no changed area in the first frame of image information, and then the transmission may not be performed, or if the person leaves during the video call, then the first frame of image information may only include a background environment, and then the background environment included in the first frame of image information may also not be changed, and then the transmission may not be performed, or although the background environment in the first frame of image information is changed, since the background environment belongs to an area corresponding to the fourth priority specified in the embodiment of the present invention, the transmission may also not be performed, so that traffic may be saved.

In the embodiment of the present invention, when the percentage value of the changed pixel points in a region to all the pixel points included in the region is not less than the preset percentage value, it may be determined that the image information included in the region is inconsistent before and after.

For example, when the first region corresponding to the first priority in the first frame of image information is compared with a corresponding region corresponding to the first priority in a previous first frame of image information, if a percentage value of changed pixels in the first region corresponding to the first priority in the first frame of image information to all pixels included in the region is not less than a preset percentage value, it may be determined that the front and back of the first image information included in the first region corresponding to the first priority in the first frame of image information are not consistent, and it may be determined that the first image information included in the first region corresponding to the first priority in the first frame of image information is changed.

Step 103: and executing the first transmission instruction, and at least transmitting the first image information to a second electronic device.

Executing the first transmission instruction may transmit at least the first image information to the second electronic device. In the embodiment of the present invention, the first image information may be image information corresponding to one priority level, or the first image information may be an area corresponding to a plurality of priority levels.

In the embodiment of the invention, only the changed image information can be transmitted, or the unchanged image information can be transmitted, so as to improve the integrity of the transmission content.

In the embodiment of the present invention, when the first image information is transmitted, the first image information may be compressed according to a certain compression ratio and then transmitted to the second electronic device.

In this embodiment of the present invention, each priority may correspond to the same compression ratio, for example, each priority may correspond to a first compression ratio, or different compression ratios may be preset for each priority, for example, the first priority may correspond to a second compression ratio, the second priority may correspond to a third compression ratio, the third priority may correspond to a fourth compression ratio, and the fourth priority may correspond to a fifth compression ratio. Wherein, since the larger the compression ratio is, the more serious the distortion may be, if a different compression ratio is set in advance for each priority, the higher the priority is, the smaller the set compression ratio may be.

When the first image information is transmitted, the first image information may be compressed according to a compression ratio corresponding to the first image information and then transmitted.

First, the first image information corresponds to only one priority.

If each priority corresponds to the first compression ratio, the first image information may be compressed according to the first compression ratio and then transmitted to the second electronic device.

If different compression ratios are preset for each priority, the first image information can be compressed according to the compression ratio corresponding to the first image information and then transmitted to the second electronic equipment. For example, if the first image information corresponds to the second priority, the first image information may be compressed according to the second compression ratio and then transmitted to the second electronic device.

And secondly, the first image information corresponds to different priorities.

If different compression ratios are preset for each priority, the first image information can be respectively compressed according to the compression ratio respectively corresponding to each priority and then transmitted to the second electronic equipment. For example, if first sub-image information in the first image information corresponds to the second priority and second sub-image information in the first image information corresponds to the third priority, the first sub-image information may be compressed according to the second compression ratio, the second sub-image information may be compressed according to the third compression ratio, and the compressed first sub-image information and the compressed second sub-image information may be transmitted to the second electronic device.

The information transmission method of the present invention is described below by using several specific embodiments, and the following embodiments describe several possible application scenarios of the information transmission method. It should be noted that the examples in the present invention are only for explaining the present invention, and are not to be construed as limiting the present invention. It is natural to the person skilled in the art how modifications can be made to the inventive concept, insofar as embodiments conforming to the inventive concept are within the scope of the invention.

The first embodiment is as follows:

first, the current network quality is judged according to the current network quality value, if the judgment result shows that the current network quality value is smaller than a preset network quality threshold value, the current network quality can be determined not to be good, and the first electronic device can be controlled to enter the first mode.

In this embodiment, the area included in one frame of image information may be divided into four priorities according to the degree of importance. In image transmission during application such as video call, people's change in video is a concern, so in one frame of image information, people's priority is higher than that of background environment. In the present embodiment, the facial expressions of the human may be preset to a first priority, the regions of the human face other than the facial expressions of the human may be preset to a second priority, the limbs of the human may be preset to a third priority, and the background environment may be preset to a fourth priority. Wherein the first priority has the highest importance level and the fourth priority has the lowest importance level.

When first frame image information needs to be transmitted, the first frame image information is compared with at least one frame image information transmitted previously according to a preset priority level, and a comparison result is generated.

In this embodiment, the first frame image information is compared with the previous mth frame image information transmitted before according to a preset priority, where M is 2 in this embodiment, that is, the first frame image information is compared with the previous second frame image information transmitted before according to the preset priority.

In this embodiment, the step of comparing the first frame of image information with the previously transmitted second frame of image information according to a preset priority includes: firstly, comparing the first image information contained in the first region corresponding to the first priority in the first frame of image information with the corresponding image information contained in the previous second frame of image information, judging whether the first image information and the previous second frame of image information are consistent, if so, continuously comparing the first image information contained in the second region corresponding to the second priority in the first frame of image information with the corresponding image information contained in the previous second frame of image information, if so, continuously comparing the first image information contained in the third region corresponding to the third priority in the first frame of image information with the corresponding image information contained in the previous second frame of image information, and thus, sequentially comparing until the comparison result is determined to be inconsistent under a certain priority, the comparison result may be generated, and the comparison result may be used to indicate that the first image information included in the first frame image information is inconsistent with the corresponding image information included in the previous second frame image information at a certain priority. Or, if all the priorities are compared, it is determined that the first image information included in the first frame image information is consistent with the corresponding image information included in the previous second frame image information at each priority, and the comparison result may also be generated, where the comparison result may be used to indicate that the first image information included in the first frame image information is consistent with the corresponding image information included in the previous second frame image information at each priority.

In this embodiment, the comparison result indicates that the first image information corresponding to the first priority in the first frame of image information and the first image information corresponding to the second priority in the first frame of image information have changed. In the embodiment of the invention, only the changed image information can be transmitted.

The first electronic device generates a first transmission instruction.

In this embodiment, different compression ratios may be preset for each priority, for example, the first priority may correspond to a second compression ratio, the second priority may correspond to a third compression ratio, the third priority may correspond to a fourth compression ratio, and the fourth priority may correspond to a fifth compression ratio.

In this embodiment, a comparison result of comparing the first frame of image information with the fourth frame of image information may be that the first image information of a first area corresponding to a first priority in the first frame of image information is changed.

In this embodiment, when comparing the first frame of image information with the fifth frame of image information, the adopted comparison method may be: the first image information included in each region corresponding to each priority in the first frame of image information and the corresponding image information included in the previous fifth frame of image information may be respectively compared to generate the comparison result.
