It will be understood that the terms "comprises" and/or "comprising," when used in this specification and the appended claims, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

The data transmission optimization method provided by the embodiment of the application can be applied to terminal devices such as a tablet computer, a notebook computer, a super-mobile personal computer (UMPC), and the like, and the embodiment of the application does not limit the specific types of the terminal devices.
Referring to fig. 1, fig. 1 shows a flowchart of an implementation of a data transmission optimization method provided in an embodiment of the present application, where the method includes the following steps:
s101, terminal equipment obtains first data information of a first cache data set in a local cache; the first cached data set includes at least one first cached data; the first data information includes at least a first total data amount of the first cache data set and a cache time of each first cache data.
In an embodiment, the device for executing the method may be a terminal device, and a plurality of first cache data may be stored in a designated storage location of the terminal device in advance, or the terminal device may obtain the first cache data in real time through network transmission. The acquired first cache data includes, but is not limited to, video data, audio data, and the like. In this embodiment, the video data is explained as an example.
In an embodiment, the local cache may be a memory of the terminal device itself, and is used for storing the first cache data set. Taking a terminal device as an example of a monitoring device, the monitoring device can generate monitoring video data in real time during operation, and the monitoring video data needs to be transmitted to a plurality of display devices in real time. However, the monitored video data received by each display device may not be the same due to various factors such as different receiving rates of each display device, network delay, and the like. Therefore, in this embodiment, the terminal device may perform merging processing on the monitored video data to be played in advance, so as to make the video pictures played by the multiple display devices consistent, and reduce the number of data interactions between the display devices and the terminal device.
It should be noted that, when the terminal device acquires the first cache data set in the local cache, the terminal device needs to store the first cache data acquired in real time in the local cache in advance, and then the terminal device may acquire the first cache data set in the local cache every preset time period.
In an embodiment, the first cached data set may include one or more first cached data, or may not include any first cached data, which is not limited thereto. It will be appreciated that when the first set of buffered data does not include the first buffered data, the first total amount of data is zero and there is also no corresponding buffering time.
In another embodiment, the first data information may further include a total amount of the first cached data in the first cached data set, and the total data amount and the caching time are only two examples, which is not limited thereto.
S102, if any first data information does not accord with a preset rule, the terminal equipment merges a plurality of first cache data in the first cache data set according to cache time to obtain a second cache data set; the second total data size of the second cache data set meets a preset rule.
In an embodiment, the step of determining that any of the first data messages does not comply with the predetermined rule may specifically be: the total data volume of the first cache data set is larger than a preset data volume; or the total number of the first cache data sets exceeds a preset number; or, the buffering time of the first cache data stored earliest in the local cache exceeds the preset interval duration, which is not limited herein.
Thus, it can be appreciated that the trigger conditions for the merging process on the first cached data set include, but are not limited to: the total data volume of the first cache data set is larger than a preset data volume; or the total number of the first cache data sets exceeds a preset number; or, the buffering time of the first cache data stored earliest in the local cache exceeds the preset interval duration, which is not limited herein.
It is understood that the total amount of data in the first cache data set exceeds the preset data amount; or, the total number of the first cache data sets exceeds a preset number; or, when the buffering time of the first cache data stored in the local cache at the earliest exceeds the preset interval time, the terminal device may further merge each first cache data in the first cache data. That is, after merging the first cached data, the first cached data set is generally divided into two parts. At this time, the terminal device may determine a portion corresponding to the first cached data including the earliest caching time as the second cached data set.
In addition, the second total data amount of the second cache data set should comply with the preset rule. I.e. the second total data amount should be less than or equal to the preset data amount. It is understood that the second cache data set includes the cache time of the first cache data stored in the local cache at the earliest time, and the cache time may exceed the preset interval duration. Therefore, in the generated second cache data set, it is not necessary to determine whether the cache time of the first cache data earliest stored in the local cache satisfies the preset rule.
The preset data amount, the preset number and the preset interval duration can be preset according to actual conditions, and are not limited.
It can be understood that, if the preset interval duration is too long, the screen display device will be in a dark screen state for a long time when the data in the second cache data set sent by the terminal device last time has been played. And if the preset data volume is too large, the picture display equipment is in a condition of receiving the second cache data set for a long time, and cannot play the data in the second cache data set in real time. If the preset interval duration is too short and the preset data amount is too small, the data interaction times of the terminal equipment and the picture display equipment cannot be reduced to the maximum extent.
And S103, the terminal equipment respectively sends the second cache data set to the multi-terminal picture display equipment for display.
In an embodiment, the screen display device includes, but is not limited to, a player, a video display, and the like. In order to ensure that the video pictures played by the multi-terminal picture display device are consistent in real time when playing video data, the video data is usually synchronized to the multi-terminal picture display device immediately when the terminal device generates the video data. However, in a short time, this process will cause the terminal device to perform a large and frequent data interaction with the multi-end screen display device.
Based on this, in this embodiment, a second cache data set is generated by merging the first cache data to be synchronized, and the second cache data set is sent to the multi-end screen display device for synchronous playing. It can be understood that the video data included in the second cache data set is generated after performing the judgment processing based on the preset rule. Therefore, on the premise of ensuring that the video data played by the multi-terminal picture display equipment is consistent in real time, the terminal equipment can also reduce the sending times of sending the video data with the multi-terminal picture display equipment.
It can be understood that, because there is only one local cache, and the terminal device sends the second cache data sets in the local cache to the multi-terminal image display device respectively, it can be considered that the second cache data sets are sent to the multi-terminal image display device simultaneously. I.e. the time at which the multi-end picture display device receives the second buffered data set is typically consistent. Based on this, each picture display device can be considered to be playing synchronously with respect to the received second buffered data set.
In this embodiment, whether to perform merging processing on each first cache data in the first cache data set is determined according to the first total data volume of the first cache data set cached in the local cache and the cache time of each first cache data. And then, when the plurality of first cache data are determined to be merged, generating a second cache data set, wherein the generated second cache data set only needs to meet the condition that the second total data amount meets the preset rule, and does not need to consider whether other data information in the second cache data set meets the preset rule. Therefore, the terminal device can trigger the merging operation of the first cache data based on the cache time of the first cache data and the first total data volume, and timely send the second cache data to the multi-terminal image display device, so that the continuity of playing videos by the multi-terminal image display device is ensured. In addition, the generated second total data volume meets the preset rule, so that the second cache data set can maximally contain the first cache data, and multiple interactions between the terminal equipment and the multi-terminal picture display equipment are reduced.
In an embodiment, referring to fig. 2, in S102, a plurality of first cache data in the first cache data set are merged according to the cache time to obtain the second cache data set, which may specifically be implemented by the following sub-steps S1021 to S1024:
s1021, the terminal device obtains the caching time of each first caching data and the data volume of each first caching data.
In an embodiment, when the first cached data set does not include any first cached data, it may be determined that no data that needs to be sent to the multi-terminal screen display device is stored in the local cache. I.e. without performing the process of merging the first set of cached data.
In an embodiment, if the first cache data set includes at least one first cache data, when the terminal device stores each first cache data, the terminal device may record a cache time of each first cache data in the local cache and a data volume of each first cache data, respectively. Taking the first cache data as the video data as an example, because the video data is continuously played based on time, the time that each first cache data is acquired and stored by the terminal device is generally continuous.
And S1022, if the caching time of the first cache data stored in the local cache at the earliest time exceeds the preset interval duration, sequentially adding and caching the data quantity of the N first cache data with the earlier caching time according to the caching time when the first total data quantity is greater than the preset data quantity by the terminal equipment.
And S1023, when the data volume of the N first cache data is smaller than or equal to the preset data volume and the data volume of the N +1 first cache data is larger than the preset data volume, the terminal equipment merges the N first cache data into a second cache data set.
And S1024, if the caching time of the first cache data which is stored in the local cache at the earliest time exceeds a preset interval duration and the total data volume of the first cache data set is less than or equal to a preset data volume, determining the first cache data set as a second cache data set by the terminal equipment.
In an embodiment, for a plurality of first cached data in the first cached data set, the first cached data that is normally in the local cache is the cached data that belongs to the oldest storage. That is, the interval between the buffering time of the first cache data stored earliest and the current time is longest. Based on this, the terminal device may calculate an interval duration between the cache time of the first cache data earliest stored in the local cache and the current time, and then calculate the total data amount of the first cache data set when the interval duration exceeds the preset interval duration.
In an embodiment, when the total data amount is greater than the preset data amount, the data amounts of the N first cache data whose cache time is earlier are sequentially added and buffered according to the cache time until the total data amount of the N first cache data is less than or equal to the preset data amount, and the total data amount of the N +1 first cache data is greater than the preset data amount. At this time, the N first cache data sets are merged to obtain a second cache data set. In addition, if the total data volume of the first cache data set is less than or equal to the preset data volume, the terminal device may directly use the first cache data set as the second cache data set.
It should be noted that, the above steps are only a case of performing merging processing on the first cache data set when the cache time of the first cache data cached in the local cache at the earliest time does not meet the preset rule first. It can be understood that the terminal device should determine whether any kind of data information complies with the preset rule in real time.
Therefore, if the caching time of the first cache data cached in the local cache at the earliest time always meets the preset rule, the terminal device may directly add and cache the data amount of the N first cache data with the earliest caching time in sequence according to the caching time when the first total data amount of the first cache data set exceeds the preset data amount until the total data amount of the N first cache data satisfies the condition that the total data amount is less than or equal to the preset data amount, and the total data amount of the N +1 first cache data is greater than the preset data amount.
For example, if the caching time of the first cache data cached in the local cache at the earliest time always meets a preset rule, when new first cache data is received at the current time, calculating whether the sum of the data volume of the new first cache data and the data volume (first total data volume) of the existing first cache data set exceeds a preset data volume; if the data volume does not exceed the preset data volume, storing the new first cache data in a local cache to obtain a new first cache data set; otherwise, the existing first cache data is directly merged into the second cache data set.
In an embodiment, based on the above description of S1024, when the buffering time of the first cache data stored earliest in the local cache exceeds the preset interval time, the total data amount of the first cache data set may be less than or equal to the preset data amount. Therefore, the total data amount of the merged second cached data set at this time has not exceeded the preset data amount. Based on this, referring to fig. 3, after the first cached data set is determined as the second cached data set, the following steps S1-S4 are further included:
and S1, if the new first cache data are received in the local cache at the current moment, the terminal device calculates the sum of the data amount between the new first cache data and the second cache data set.
In an embodiment, the new first cache data is data acquired by the terminal device at the current time, and in a normal case, when the terminal device acquires the new first cache data, the data should be stored in the local cache. At this time, when the second total data volume of the already generated second cache data set does not exceed the preset data volume, the terminal device may further merge the new first cache data with the second cache data set.
And S2, if the sum of the data volumes is less than or equal to the preset data volume, the terminal equipment merges the first cache data into the second cache data set to obtain a new second cache data set.
And S3, the terminal equipment repeatedly executes the steps S1-S2 to update the second cache data set.
And S4, if the sum of the data volume is larger than the preset data volume, the terminal equipment sends the second cache data set to the multi-terminal picture display equipment.
In an embodiment, based on the above description of the second cached data set, it can be known that the total data amount of the second cached data set should be less than or equal to the preset data amount in this case. Based on this, at the current time, if new first cache data is received, the terminal device may perform the following determination process. Specifically, the second total data size is added to the data size of the new first cache data. And if the summed total data amount exceeds the preset data amount, sending the original second cache data set to the multi-terminal picture display equipment. And if the total data volume after the summation does not exceed the preset data volume, merging the first cache data and the original second cache data set to obtain a new second cache data set. And then, judging whether new first cache data are cached in the local cache at the current moment again, and repeatedly executing the steps. Therefore, the data volume of the second cache data set sent by the terminal device each time is maximized.
It should be noted that if the above steps S1-S2 are repeated all the time, the time for the terminal device to send the second buffer data to the multi-screen display device may be delayed. Therefore, referring to fig. 3, after repeatedly performing the steps S1-S2 at S3 to update the second cached data set, the terminal device may further include the following steps S5-S7 to process the second cached data set:
s5, the terminal device counts the execution time length for repeatedly executing the steps S1-S2.
And S6, if the execution duration exceeds the preset execution duration, the terminal device acquires a second cache data set updated after the preset execution duration is executed.
And S7, the terminal equipment respectively sends the updated second cache data set to the multi-terminal picture display equipment.
In an embodiment, the preset execution time may be set by a user according to an actual situation, which is not limited. Generally, in order to ensure the continuity of the video played by the multi-terminal image display device, the preset execution time period may be set to a shorter time period, for example, a time period of 5 seconds or 10 seconds.
It is to be added that the purpose of setting the preset execution duration is to: the interaction times of the terminal equipment and the multi-terminal picture display equipment are reduced as much as possible under the condition that the multi-terminal picture display equipment can continuously play videos.
It is understood that if the new first buffered data received at the current time is not merged into the second buffered data set, the new first buffered data will need to be transmitted next time. And under the condition that the subsequent first cache data to be processed does not exist, increasing the data interaction times of the terminal equipment and the multi-terminal image display equipment.
Based on this, the terminal device may also set a judgment condition for terminating the repetition step when performing the repeated process. Specifically, the execution duration of repeatedly executing the steps S1-S5 is recorded, and when the execution duration exceeds the preset execution duration, a new second cache data set updated after the preset execution duration is executed is obtained. Namely, after the preset time length is reached, the updating of the second cache data set is stopped, and the updated new second cache data set is sent to the multi-terminal image display device.
In an embodiment, referring to fig. 4, after the second cached data sets are respectively sent to the multi-terminal screen display device for display in S103, the terminal device may further process the second cached data sets through the following steps S131 to S135:
s131, if response data returned by each terminal of the image display equipment are received within the target time length and the response data all represent that the second cache data set is completely received, the terminal equipment deletes the second cache data set from the local cache.
S132, if not, the terminal equipment reserves the second cache data set in the local cache.
In an embodiment, the target duration may be set by a worker according to actual conditions, and the target duration should be a shorter duration in case of a smooth network. For example, a duration of 1s-5 s. Wherein, the response data is the data returned by the picture display equipment. Which includes the response result of the received complete second cached data set and the response result of the received incomplete second cached data set (i.e., there was a loss during the data transmission)
The image display device determines whether the received second cached data set is complete as in the prior art, which is not described in detail. It should be added that if the screen display device does not receive the second cached data set, the screen display device will not return any response data.
It can be understood that, if the response data returned by each terminal of the screen display device is not received within the target duration, or the received response data does not represent that the second cache data set is completely received, it indicates that the screen display device needs to obtain the complete second cache data set from the terminal device again. Therefore, the second cached data set in the local cache needs to be maintained.
However, if the second cached data set is always reserved in the local cache, it will affect the process of receiving and merging the new first cached data by the terminal device, so after S132, the terminal device may further perform the following steps S133-S135 to process the second cached data set in the local cache:
s133, aiming at the target picture display equipment which does not return response data in the target time length or the response data represents that the second cache data set is lost, the terminal equipment continuously issues the second cache data set to the target picture display equipment for preset times.
And S134, if the response data returned by the target picture display device is not received in the target time length within the continuous preset times or the response data represent that the second cache data set is lost, the terminal device disconnects a data transmission channel with the target picture display device.
And S135, the terminal equipment deletes the second cache data set in the local cache.
In an embodiment, the preset number of times may be three times, and may be specifically set according to an actual situation.
