For example, the data process that data of a certain video type needs to go through includes: fig. 2 is a schematic view of a processing flow of video data provided in the second embodiment, and as shown in fig. 2, the processing flow of video-type data is as follows: video acquisition and audio acquisition, video rendering (audio rendering), video coding (audio coding), audio embedding, then with the data transmission that the embedding is good to the high in the clouds storage, further can carry out data acquisition from the high in the clouds, carry out video decoding (audio decoding), finally carry out operations such as rendering. Correspondingly, the functional modules involved in the data processing process may include: the device comprises an acquisition module, an encoding module, a storage module, an extraction module, a decoding module, a rendering module and the like. And the transmission path of the data in the processing process of the video type data is as follows in sequence: the device comprises an acquisition module, an encoding module, a storage module, an extraction module, a decoding module and a rendering module. Therefore, any functional module may be regarded as an upstream functional module and/or a downstream functional module of a certain functional module on the corresponding transmission path, for example, the acquisition module is an upstream functional module of the encoding module, the storage module is a downstream functional module of the encoding module, and the encoding module is a downstream functional module of the acquisition module. Data may be transferred from an upstream functional module to a downstream functional module corresponding thereto.
The data management platform may be implemented by software and/or hardware, and may be configured in an electronic device, the electronic device including a terminal or a server, as shown in fig. 1, and the method includes:
s110, any target upstream function module sends a data transmission request to at least one corresponding downstream function module.
The functional module can be specifically set according to the specifically processed service content, type and data transmission path condition. Any functional module in a certain data transmission path can be taken as any target upstream functional module, and there can be one or more corresponding downstream functional modules. And a plurality of corresponding downstream function modules can have the same attribute function or different attribute functions. Similarly, a certain downstream functional module may also correspond to one or more upstream functional modules.
The acquisition module is illustratively a target upstream functional module, and may have one or more acquisition modules, such as a video data acquisition module, an audio acquisition module, a picture acquisition module or a text acquisition module, and the like, and the corresponding downstream functional module may be one or more functional modules. In the case of a downstream functional module, the downstream functional module, such as the acquisition module, comprises only one coding module. For the case of multiple downstream functional modules, the multiple downstream functional modules may specifically have the same attribute function and/or different attribute functions, for example, multiple encoding modules may exist, and different encoding modules may inherit the same parent class, all have encoding attributes, and may encode different types of data or data at different times.

That is, the relationship between the upstream functional module and the downstream functional module may be one-to-one, one-to-many, many-to-one, or many-to-many, and may be set according to specific service requirements.
Any target upstream functional module can send a data transmission request to one or more corresponding downstream functional modules, and the transmission request can include the module identification of the target upstream functional module, so that the downstream functional module can determine the module and the address for sending the data request.
S120, each downstream functional module responds to the data transmission request, allocates data transmission identifiers for the target upstream functional module respectively, and sends the respective module identifiers of the downstream functional modules and the allocated data transmission identifiers to the target upstream functional module respectively.
After receiving the data transmission request, the downstream functional module may allocate a data transmission identifier to a target upstream functional module that sends the data transmission request, where the data transmission identifier may be used to identify and determine whether the data is sent by the corresponding upstream functional module when data transmission is performed between the functional modules. And each downstream functional module sends the respective module identification and the distributed data transmission identification to the corresponding target upstream functional module. The module identifier of the downstream functional module can facilitate the upstream functional module to identify which module is assigned the data transmission identifier.
S130, the target upstream function module determines an address of a downstream function module receiving data to be transmitted according to the received module identifier, and transmits the data to be transmitted to at least one corresponding downstream function module according to the address, wherein the data to be transmitted also carries a data transmission identifier distributed by each downstream function module.
After receiving the sending module identifier and the data transmission identifier of each downstream functional module corresponding to each target upstream module, each target upstream module can determine the address of each downstream module according to each module identifier, and then send the data to be transmitted to the corresponding address, wherein the data to be transmitted can carry the data transmission identifier distributed by the corresponding downstream functional module besides specific service data, so that the downstream module can quickly and conveniently identify the transmission data sent by which functional module, and the subsequent calling and processing of the data.
Optionally, the module identifier includes a module pointer, and the module pointer may be a number of a certain memory unit in the platform, and is used to indicate an address of the module, so that identification and accurate data transmission between the functional modules are facilitated.

In this embodiment, the upstream functional module performs data transmission with the downstream functional module according to the data transmission identifier and the downstream module identifier allocated by the downstream functional module, and the downstream functional module can determine the source and destination of transmission data by identifying the data transmission identifier, so that data transmission between modules and processing and calling of subsequent data can be more convenient and flexible, and the modular link management is applicable to various operating systems, and developers can customize module functions and connection relationships according to business processing requirements, so that the development complexity is low, and the period is short.
Example two
Fig. 3 is a flowchart of a data transmission method provided in a second embodiment of the present invention, and based on the above embodiment, as shown in fig. 3, the data transmission method includes:
s210, any target upstream function module sends a data transmission request to at least one corresponding downstream function module.
S220, each downstream functional module uses a counter to allocate index data identification to the target upstream functional module sending the data transmission request according to the time sequence of sending the data transmission request, the index data identification is used as the data transmission identification, and the respective module identification of the downstream functional module and the allocated data transmission identification are respectively sent to the target upstream functional module.
In particular, the counter may be a hardware device or a software program for counting certain programs or tasks according to certain trigger instructions, for example, an instruction address may be counted to sequentially fetch a next instruction, and count down the number of additions, subtractions, and the like when performing multiplication and division operations in the arithmetic unit. The data transmission request sent by the upstream functional module to the downstream functional module corresponding to the upstream functional module may serve as a trigger condition for triggering the counter to work. The index data identifier is used as a data transmission identifier, and may be a protocol or a convention manner for data transmission between the upstream functional module and the downstream functional module corresponding to the upstream functional module. In this embodiment, the index data identifier may be an index value identifier assigned by a counter, for example, the index is 1,2 or another value, and for example, the counter may assign an index value identifier to a target upstream functional module corresponding to the counter as a data transmission identifier in a manner of increasing the value according to a time sequence of sending the data transmission request, and then send a module identifier of each downstream functional module and the assigned data transmission identifier to the target upstream functional module respectively.
S230, the target upstream function module determines an address of a downstream function module receiving data to be transmitted according to the received module identifier, and transmits the data to be transmitted to at least one corresponding downstream function module according to the address, wherein the data to be transmitted also carries a data transmission identifier distributed by each downstream function module.
Optionally, after each downstream functional module sends the respective module identifier of the downstream functional module and the allocated data transmission identifier to the target upstream functional module, the method further includes:
and each downstream functional module adds the corresponding target upstream functional module identification and the corresponding data transmission identification to the effective connection number array corresponding to each downstream functional module.
Specifically, each downstream functional module may have an effective connection number array corresponding thereto, where the effective connection number array is used to record module identifiers of all upstream functional modules that establish connection with the downstream functional module to perform data transmission and corresponding data transmission identifiers. The subsequent functional module can quickly determine the source of the data according to the effective connection number array, so that the subsequent data can be conveniently transmitted, processed or called. It will be appreciated that each functional module may be referred to in various instances as an upstream functional module or a downstream functional module, i.e., each functional module may have an array of valid connection numbers associated therewith.
For example, fig. 4 is a schematic diagram of data transmission between functional modules according to a second embodiment of the present invention. As shown in fig. 4, the target upstream functional module includes a module a, a module B, and a module C, the downstream functional modules corresponding to the three upstream functional modules are all a module D (i.e., a many-to-one relationship), and A, B, C in the figure sequentially sends a data transmission request to the module D, and then establishes an Index connection counter and an effective connection number array m _ pconectedindex for the module D, assuming that the initial value of the Index is 0, and every time the module D is connected by other modules, the Index is incremented by 1, and remains unchanged when the module D is disconnected by the previous module. For example, module a connects to module D first, and module D first returns its module pointer and index to 0 for module a to save, and adds the current index value and the module identifier of module a to the array m _ pConnectedIndex. Then index plus 1 equals 1, then module B connects to module D second, module D returns its module pointer and index equal to 1 to module B and adds the current index value and module identification of module B to the array m _ pConnectedIndex. And then adding 1 to the index to be equal to 2, namely, the index data identifier of the module C is 2, and so on. Of course, the module A, B, C may also be used as a downstream functional module of their respective upstream functional modules, or may have an array of valid connection numbers m _ pConnectedIndex corresponding thereto. In such a technical scheme, when the link connection between modules is completed, and a program data stream runs, and a previous module calls a Receive method of a next module or transmits data to the next module, the next module can distinguish which module the transmitted data comes from according to an index value as long as the index value (data transmission identifier) stored when the connection is established is transmitted as a parameter.
For example, fig. 5 is a schematic diagram of data transmission between other functional modules according to a second embodiment of the present invention. As shown in fig. 5, the output of the module D is sequentially connected to the input of the E, F, G modules, that is, a one-to-many relationship is formed, in an application, the module D may sequentially call Receive methods of the E, F, G modules to perform data transfer, when the module D is connected to the module E, the module D may store a module pointer and an assigned index value of the module E in an internally maintained downstream module array m _ pNextModules, after connection is respectively established with the module E, F, G, corresponding three records may be stored in the m _ pNextModules array, and when data needs to be transferred downstream, data transfer may be completed by sequentially calling Receive functions of each module in the array.
Optionally, after the target upstream functional module respectively transmits the data to be transmitted to the corresponding at least one downstream functional module according to the address, the method further includes:
and when the target upstream functional module is disconnected from the downstream functional module, the target upstream functional module deletes the stored corresponding downstream functional module identification and the corresponding data transmission identification.
Optionally, after the target upstream functional module respectively transmits the data to be transmitted to the corresponding at least one downstream functional module according to the address, the method further includes:
and when the target upstream function module is disconnected from the downstream function modules, deleting the target upstream module identification and the corresponding data transmission identification stored in the corresponding effective connection number array by each downstream function module.
Specifically, when the connection between the upstream functional module and the corresponding downstream functional module is disconnected, or when the previous module actively disconnects the next module, for example, when the module a disconnects the module D after the data transmission is completed, the module a may delete the module pointer and the data transmission identifier index value of the module D stored inside.
In addition, the module D can also delete the index value allocated when the modules a and D are connected and the corresponding identifier of the module a from the effective connection number array of the module D, so as to ensure that all the identifiers stored in the effective connection number array are the effectively connected module identifiers and data transmission identifiers, release the system memory, reduce the system resource occupation, and improve the platform data processing speed and efficiency.
In the technical scheme of the embodiment of the invention, the downstream function module utilizes the technology counter to distribute the data index numerical value identification for the upstream function module, the downstream function module can determine the source and the destination of transmission data by identifying the data transmission identification carried in the transmission data, so that the data transmission and calling among the modules can be more convenient and flexible, meanwhile, the modularized link management can be suitable for various operation platforms, such as a Windows/Linux/Mac platform, an Android and IOS mobile platform and the like, and a developer can customize the functions and the connection relation of the modules according to business processing requirements.
