In the following description, suffixes such as "module", "component", or "unit" used to denote elements are used only for facilitating the explanation of the present invention, and have no specific meaning in itself. Thus, "module", "component" or "unit" may be used mixedly.
As shown in fig. 1, the data matching method of the present invention is applied to a display terminal, and fig. 1 is a schematic structural diagram of the display terminal in a hardware operating environment according to an embodiment of the present invention.
The display terminal of the embodiment of the invention can comprise a plurality of devices supporting remote control functions, such as a smart phone, a television and the like.

The network interface 1004 may optionally include a standard wired interface, a wireless interface (e.g., WI-FI interface). The memory 1005 may be a high-speed RAM memory or a non-volatile memory (e.g., a magnetic disk memory). The memory 1005 may alternatively be a storage device separate from the processor 1001.
Those skilled in the art will appreciate that the display terminal configuration shown in fig. 1 does not constitute a limitation of the display terminal, and that the display terminal may include more or less components than those shown, or some components may be combined, or a different arrangement of components.
As shown in fig. 1, a memory 1005, which is a kind of computer-readable storage medium, may include therein an operating system, a network communication module, a user interface module, a data matching program.
In the display terminal shown in fig. 1, the network interface 1004 is mainly used for connecting to a background server, and performing data communication with the background server, so that data in a code stream can be transmitted; the user interface 1003 is mainly used for connecting other mobile terminals or servers and performing data communication with the other mobile terminals or servers; and the processor 1001 may be used to invoke a data matching program stored in the memory 1005.
Based on the system architecture, the mobile terminal hardware structure and the communication system, the data matching method provided by the invention has various embodiments.
The invention provides a data matching method, in a first embodiment of the data matching method, referring to fig. 2, the method comprises:
step S10, caching the code stream data received within a preset time before the current time of the display terminal to generate cache data, and marking a timestamp corresponding to the code stream data time for each application data in the cache data;
the Cache is a buffer area (called Cache) for data exchange, when data is to be read by a certain hardware, the required data is firstly searched from the Cache, if the required data is found, the data is directly executed, and if the required data is not found, the required data is found from a memory. Since caches run much faster than memory, the role of caches is to help the hardware run faster.
The preset duration is a fixed duration set in advance by a display terminal system or set by a user, and the code stream refers to the data flow used by the video file in unit time and is also called code rate, and is the most important part in picture quality control in video coding; a time stamp is a mark, usually a sequence of characters, that represents a complete, verifiable piece of data that exists before a particular time, uniquely identifying the time of a moment. In the process of sending data to the display terminal by the code stream data, the display terminal caches only the code stream data received within a preset time period before the current time so as to generate cache data, the display terminal caches only the code stream data received within a fixed time period preset by a display terminal system or set by a user, and does not cache other data, and time stamps corresponding to the code stream data time are marked on each application data in the cache data, namely, the code stream data received within the preset time period is cached at the display terminal so as to generate the cache data, and simultaneously, time stamps corresponding to the code stream data time need to be marked on each application data in the cache data so as to feed back a time point when the display terminal matches corresponding target application data in the cache data.
For example, taking a segment of 60 seconds of data in the code stream as an example, at the current time, the code stream already transmits data of-1 to-19 seconds to the display terminal, then the data of-1 to-19 seconds are cached, and the cached data all mark a timestamp corresponding to the time of the code stream data.
Further, the display terminal acquires required demand information according to the requirements of the user, and sends matching request information to the code stream, for example, when the display terminal is a television, a channel of the television is changed, when the user changes the channel as required, the user sends information of a channel changing instruction to the television through key operation or sliding operation, and when the television receives the information of the channel changing instruction, the matching request information is sent to the code stream through an interface based on a certain preset logical relationship.
Step S20, when a data matching request is detected, matching target application data corresponding to the data matching request from the buffer data;
when data matching request information sent by a display terminal to code stream data based on an interface is received, code stream cache data received within a preset time length before the current time of the display terminal is matched with display terminal application, target application data required by the display terminal application is matched, namely the display terminal application only matches with the code stream cache data received within the preset time length and does not match with other data, waiting is not needed in the data matching process, the display terminal application can be directly matched with the next cache data without delay until the target application data corresponding to the data matching request in the display terminal application and the cache data are successfully matched, and time is saved when the display terminal application matches the data.
For example, when the display terminal is a computer, taking a text folder in the computer as an example, if there are 3 data points 10, 11, and 12 in a section of code stream, the current text folder needs data 12, and the text folder is firstly matched with the data 10 based on a preset logical relationship, and if the matching is unsuccessful; then the match is made with data 11 immediately without delay and the match is unsuccessful; the match with the data 12 is made immediately without delay and the match is successful.
Step S30, if the target application data are matched in the cache data, obtaining effective target application data with a timestamp in a preset effective time interval;
if the display terminal application is matched with the target application data, the timestamp of the effective target application data in the preset effective time interval is required to be acquired, namely the time point when the display terminal application is matched with the target application data is required to be fed back, so that the data sequence in the code stream data is ensured to be normally sequenced, the overdue data is not provided for the display terminal application for matching, wherein the overdue data refers to cache data which is matched by the display terminal application but is not successfully matched, and the phenomena of data confusion and damage to a data stream system of the ISO13818-6 standard are avoided. The stability of the code stream data of the display terminal is ensured when the display terminal is matched with the target application data in the cache data.
For example, in the display terminal, taking a piece of cache data with a preset duration of 60 seconds as an example, if the target application data is exactly located at the data position of the-19 second in the piece of cache data, when the display terminal applies the target application data exactly matched with the data position of the-19 second, the currently matched time point, that is, the timestamp corresponding to the target application data, that is, the-19 second is immediately fed back.
In this embodiment, the display terminal application caches, according to the user's demand information, code stream data received within a preset time before the current time of the display terminal, so as to generate cache data, and marks a timestamp corresponding to the code stream data time for each application data in the cache data; when detecting that the data sent by the display terminal matches the request information, the display terminal application matches the target application data corresponding to the data matching request from the buffer data, and if the target application data is matched from the buffer data, the effective target application data with the timestamp in the effective time interval needs to be obtained. Therefore, the stability of the data sequence in the code stream is ensured, the expired data is not provided for the display terminal to be matched any more, and meanwhile, the technical problem that the application data matching speed is too low due to the fact that long-time waiting is easy to occur in the conventional data matching method when data matching is carried out is solved, so that the data matching speed is higher, the efficiency is higher, the waiting time is shortened for a user, and the experience effect is improved.
A second embodiment of the data matching method according to the present invention is further proposed on the basis of the first embodiment of the present invention, which is a refinement of step S20 of the first embodiment of the present invention, and referring to fig. 3, step S20 includes:
step S21, when a data matching request is detected, sequencing each application data based on the time sequence order of the time stamps of each application data in the cache data to generate an application data sequence;
and step S22, matching the data identification corresponding to the data matching request with each application data in the application data sequence one by one, and taking the application data matched with the data identification as target application data.
The data identification can be used for determining target application data required by the display terminal application, and sequencing data in the cache data by introducing a time axis concept (by means of an internet technology, events on one side or multiple sides are connected in series according to a time sequence to form a relatively complete recording system and then displayed to a user in a picture and text mode). The data are sequenced according to the time sequence of the time stamps of the application data in sequence, namely, in the cache data with the time stamps received by the display terminal, the data are sequenced according to the sequence in the process of sending the data to the display terminal in sequence, so that an application data sequence is generated in the display terminal for the display terminal to use for matching, and the display terminal uses the data identification corresponding to the data matching request to match with the application data in the cache data one by one in the sequencing mode, so that certain data are prevented from being missed in the process of matching the cache data with the application data of the display terminal, and the accuracy of data matching is improved. Referring to fig. 4, the cache data is sequentially sorted from the-60 th data to the-1 st data according to the time sequence of the timestamps of the application data in the cache data, so as to be matched by the display terminal application.
Specifically, the step of sorting the application data in the cache data to generate the application data sequence includes:
step S23, dynamically discarding code stream data in which the time interval between the timestamp and the current time exceeds the preset time length in the cache data in the process that the display terminal continuously receives new code stream data;
the dynamic discarding may be code stream data that is determined whether a time interval between a timestamp in the cache data and the current time exceeds a preset duration, if so, discarding outdated data, and if not, not discarding; in the process that a display terminal continuously receives new code stream data, if the length of the new code stream data received by the display terminal does not exceed the length of the code stream data with preset duration, the new code stream data is not discarded, if the length of the new code stream data received by the display terminal exceeds the length of the code stream data with preset duration, the code stream data with the timestamp exceeding the preset duration from the current time interval in the cache data is discarded, only the data with the preset duration is discarded, namely the cache data exceeds the preset duration, the cache data is discarded regardless of whether the display terminal is matched or not, the display terminal application and the cache data are not matched, but the cache is not discarded within the preset duration, and only when the cache data exceeds the preset duration, the cache data is discarded. For example, taking 60 seconds of buffered data as an example, if the current time passes 10 seconds, the data of-60 seconds is discarded, and only the data within-50 seconds is retained, and the preset duration is 60 seconds. Therefore, the phenomena that the system runs unsmoothly, non-key applications are closed and deleted by the system, the system is restarted and the like due to the fact that a large amount of memory of the display terminal is occupied by data are avoided.
Step S24 continues to cache the new code stream data to update the cache data.
Furthermore, when a data matching request is detected, the data in the code stream continuously sends application data to the display terminal for caching, so that cached data is formed, the cached data in the display terminal is updated in real time, the cached data in a preset time length is ensured not to be interrupted when the cached data is matched with the display terminal application, and the time of the success rate of data matching is prolonged. For example, when the time length set by the display terminal is 60 seconds at the current time, the data in the code stream has sent 60 seconds of application data to the display terminal, the display terminal also buffers the application data and stamps a time stamp to form buffer data, and after 10 seconds of time elapses, the code stream has sent 70 seconds of data to the display terminal, that is, the sending has never been stopped.
In the embodiment, in the preset duration, the display terminal sorts the cache application data with the timestamp transmitted in the code stream, and matches the cache application data with the display terminal application according to the sorting mode, thereby avoiding missing some data when the display terminal application matches the cache data, and in the matching process, constantly updating the cache data in the preset duration, discarding old cache data, so that the data matching time is uninterrupted, the user waiting time is reduced, and the technical problem that the application data matching speed is too slow due to long-time waiting easily occurring when the conventional data matching method matches data is solved.
Based on the first embodiment, a third embodiment of the data matching method for a display terminal application according to the present invention is provided, where in this embodiment, after step S20, the method further includes:
step S40, if the target application data is not matched in the cache data, matching the target application data in new code stream data continuously received by the display terminal until the target application data is matched;
if the display terminal application is not matched with the target application data, the code stream continuously sends data to the display terminal for caching to generate cached data, so that the display terminal can be continuously matched until the matching is successful, and the target application data does not need to be subjected to timestamp validity detection after being matched, and can be directly used as valid target application data for matching of the display terminal application.
In this embodiment, when the display terminal application is matched with the data in the code stream, and the data in the display terminal application and the code stream is matched with the first data, the display terminal application and the data in the code stream are not matched, and do not need to wait for a period of time to match the next code stream data. The method has the advantages that the interval time between the display terminal application and the code stream data matching is shortened when a user uses the display terminal application, the data matching efficiency is further improved, and the technical problem that the application data matching speed is too slow due to the fact that long-time waiting is easy to occur when the conventional data matching method is used for data matching is solved.
Based on the first embodiment, a fourth embodiment of the data matching method for a display terminal application according to the present invention is provided, and referring to fig. 5, in the embodiment, the data matching method includes:
step S50, judging whether the residual memory space of the display terminal is smaller than a preset space value, and if the residual memory space is smaller than the preset space value, outputting an adjustment prompt of the preset time length;
the preset space value may be a memory space value occupied by the code stream data received by the display terminal in a system memory space within a preset duration; whether the residual memory space of the display terminal is smaller than a preset space value or not can be determined according to whether the display terminal system runs smoothly or whether non-key applications are deleted by the system or not, and the like. For example, when the display terminal is a television, a user can feel an obvious pause phenomenon and find that some non-critical application software cannot be opened when operating the television, and the television reminds people that the current memory space is insufficient and the available memory space is very small, and at the moment, the user needs to adjust the internal memory space of the mobile phone.
Step S60, adjusting the preset duration according to an adjustment instruction input by a user based on an adjustment prompt;
if an adjusting instruction sent by a user is obtained, the cached code stream data received by the display terminal in the preset time before the current time can be adjusted according to the adjusting instruction sent by the user, if the remaining memory space of the display terminal is found to be insufficient and the available remaining memory space of the display terminal is very small, the preset time can be reduced, namely the adjusting time corresponding to the adjusting instruction is reduced, the reduced adjusting time is set as the preset time, and the cached code stream data received by the system memory in the same time period is reduced; the normal operation of the display terminal is prevented from being influenced. However, if the remaining memory space of the display terminal is very sufficient and the user wants to accelerate the data matching response time, the user can also adjust the preset time length to achieve the purpose of the user, and the length of the preset time length is increased, that is, the adjustment time length corresponding to the adjustment instruction is increased, and the increased adjustment time length is set as the preset time length, so that the buffer code stream data received by the memory space of the system in the same time period is more, the application of the display terminal can be faster and more effectively matched with the buffer data, and the data matching time of the application of the display terminal is accelerated. Meanwhile, the phenomena that the system runs unsmoothly, non-key applications are closed and deleted by the system, the system is restarted and the like due to the fact that a large amount of system memory is occupied are avoided.
In this embodiment, in the technical solution of the step of determining whether the remaining memory space of the display terminal is smaller than the preset space, specifically, the method includes the following steps:
step S51, if the residual memory space is smaller than the preset space value, judging whether the matching success rate of the current target application data of the display terminal is larger than the preset matching value;
the preset matching value can be a preset power value of target application data corresponding to the matching request from the buffer data by the statistically counted display terminal; if the residual memory space of the display terminal is smaller than the preset space value, that is, the memory space occupied by the past application data sent to the display terminal by the code stream is larger in a fixed time period, and when the residual memory space of the display terminal is insufficient, it is required to judge that the current target application data matching success rate of the display terminal cannot meet our requirements, that is, to see whether the time for the display terminal to match the target application data is fast or not.
Step S52, if the success rate of the target application data matching is larger than a preset matching value, outputting a first adjustment prompt for reducing the preset duration;
when the remaining memory space of the display terminal is smaller than the preset space value, if the matching success rate of the target application data is larger than the preset matching value, namely the time that the display terminal application can successfully match the target application data in the cache data is faster than the expected matching success time, the preset time length in the display terminal can be adjusted according to the first adjustment instruction, the preset time length is adjusted to be smaller according to the first adjustment instruction, correspondingly, the memory space of the system occupied by the cache data is reduced until the remaining memory space of the display terminal is not smaller than the preset space value, and therefore the normal operation of the display terminal can be prevented from being influenced.
And step S53, if the success rate of the target application data matching is less than or equal to a preset matching value, outputting a second adjustment prompt for increasing the preset duration, and releasing the memory space occupied by the non-critical application preset by the display terminal.
When the remaining memory space of the display terminal is smaller than the preset space value, if the matching success rate of the target application data is found to be smaller than or equal to the preset matching value, that is, the time that the display terminal application can successfully match the target application data in the cache data is slower than the expected matching success time, the preset duration in the display terminal can be adjusted according to the second adjustment instruction, the preset duration is increased according to the second adjustment instruction, and the memory space occupied by the non-critical application in the display terminal is released, so that the time that the display terminal application matches the target application data corresponding to the data matching request from the cache data is prolonged under the condition that the normal operation of a display terminal system is not affected.
In the embodiment, the preset duration is dynamically adjusted by judging whether the remaining memory space of the display terminal meets the preset spatial value, so that the technical problem that the application data matching speed is too low due to the fact that long-time waiting is easy to occur when a conventional data matching method is used for data matching is solved, meanwhile, the adverse conditions that the display terminal system runs unsmoothly and the like are avoided, and the stability of the system memory space running is ensured.
In addition, referring to fig. 6, an embodiment of the present invention further provides a data matching apparatus, where the data matching apparatus includes:
