For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described in conjunction with the embodiments, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
At present, the traditional television news production process generally refers to that a reporter returns to a television station to upload external shooting materials to a non-editing system through the intranet of the television station after finishing external shooting on site, so that editing production of the materials can be started. Thus, the conventional television news production method has the following defects: the time that the reporter brings the external photographing material back to the television station from the external photographing site and uploads the external photographing material to the non-editing system cannot be fully utilized, so that a later editing manufacturer cannot process the external photographing material at the first time, and the timeliness of the manufactured television news is weaker; the existing feedback technology (such as LiveU feedback technology) still needs to screen and transmit the content of the external shooting material after the external shooting is completed, and cannot really realize the instant shooting and instant transmission of the external shooting material; the existing 4G/5G return technology supports that the external photographing material is returned to an FTP server set in a television station, and the external photographing material is further transferred to a non-editing system through the FTP server, but the mode requires complicated manual uploading operation, and therefore labor cost is high. Based on the above, the real-time feedback system and the real-time feedback method for the out-shooting material can improve news production efficiency and further enhance news timeliness.
For the convenience of understanding the present embodiment, first, a detailed description will be given of an external photographing material real-time feedback system disclosed in the present embodiment, and referring to a schematic structural diagram of the external photographing material real-time feedback system shown in fig. 1, the system may include: FTP server 1, migration server 2, and repository server 3.
The FTP server 1 is configured to receive the material files and metadata corresponding to the material files uploaded by the material collector 4; wherein, the material collector 4 is provided with a communication module 41, and the ftp server 1 is in communication connection with the material collector 4 through the communication module 41.
Specifically, the material may be video information, image information, audio information, text information, etc., so the material collector 4 may select, according to the information type of the material, a device capable of collecting the material, such as a video camera, a recorder, a text scanner, etc., and may specifically select itself according to actual needs, which is not limited. The communication module 41 may be a 4G/5G network device capable of realizing wireless data transmission, such as a wireless router, and may specifically be selected according to actual needs, which is not limited thereto.
When using material collector 4 to gather the material, especially to the circumstances that needs to gather a large amount of materials in order that the later stage preparation personnel make certain news, in order to improve the flexibility that the material gathered and guarantee the efficiency of material passback, the material collection personnel can adopt the mode of gathering in batches to material collector 4 can adopt the mode of transmission in batches to upload the material to FTP server 1. Taking the material as video information and taking the material collector 4 as a camera as an example, when an external shooting image staff records a video (such as a video of 1 hour) by using the camera, each time a start recording button on the camera is pressed and a pause recording button on the camera is pressed, a video clip file (such as a video clip of 15 minutes) and metadata corresponding to the video clip file (such as an XML file corresponding to the video clip file) can be automatically generated on the camera, the external shooting image staff can press the start recording button and the pause recording button for a plurality of times according to the actual time sequence to sequentially generate metadata corresponding to a plurality of video clip files and different video clip files on the camera according to the time sequence, further recording of a video (including a plurality of video clip files) is completed, and the communication module 41 configured on the camera can be used for uploading the plurality of video clip files forming a video and the metadata corresponding to each video clip file to the FTP server 1 according to the time sequence through an FTP transmission protocol.
The migration server 2 is in communication connection with the FTP server 1, and is configured to obtain a material file (such as a video clip file) received by the FTP server 1 and metadata corresponding to the material file based on a synchronous transmission mechanism, and parse and store the metadata into the relational database 21; the relational database 21 stores therein the entry address information corresponding to the metadata.
Specifically, when a material collection person starts to collect the same material in a batch collection manner (for example, records a plurality of video clips according to time sequence to form the same video segment), and the material collector 4 starts to upload a first batch of material files (as the first video clip in the same video segment) in the same material to the FTP server 1 in a batch transmission manner, the FTP server 1 starts to receive the material files uploaded by the material collector 4 and metadata corresponding to the material files, and the migration server 2 can synchronously transmit the material files received by the FTP server 1 and the metadata corresponding to the material files to the migration server 2 through a synchronous transmission tool, then analyze the metadata to extract the content of the metadata, write the content of the metadata into the relational database 21, and further complete the pre-construction process of the relational database 21; in the pre-construction process of the relational database 21, it is also necessary to store the entry address information corresponding to the metadata in the relational database 21.
The migration server 2 is further configured to store the material files in a storage area corresponding to the warehouse-in address information in the repository server 3.
Specifically, since the plurality of material files corresponding to the same material have the same storage address information, when the migration server 2 continuously acquires the plurality of material files corresponding to the same material and metadata corresponding to different material files received by the FTP server 1, the storage address information corresponding to the metadata stored in the relational database 21 can be directly read, and further, a storage area corresponding to the storage address information in the resource library server 3 is determined according to the storage address information, and the plurality of material files corresponding to the same material are directly stored in the storage area.
According to the real-time feedback system for the externally-shot video, which is provided by the embodiment of the invention, the material files acquired by the material acquisition device and the metadata corresponding to the material files are uploaded to the FTP server through the communication module configured on the material acquisition device; then, acquiring the material files and the metadata corresponding to the material files received by the FTP server through the migration server based on a synchronous transmission mechanism, and analyzing and storing the metadata into a relational database containing the warehouse-in address information corresponding to the metadata; and finally, storing the material files to a storage area corresponding to the warehouse-in address information in the resource library server through the migration server. By adopting the technology, the external shooting material can be transmitted back to the resource library in real time, and the rear material editing personnel can process the external shooting material fragments in real time, so that the news production efficiency can be improved, and the timeliness of news can be further enhanced.
In order to further improve the backhaul efficiency, the migration server 2 may be further configured to poll the file directory of the FTP server 1 according to a preset time period, determine a new material file and metadata corresponding to the material file, and obtain the new material file and metadata corresponding to the material file from the FTP server 1 in an incremental copy manner.
Specifically, as the FTP server 1 continuously receives the material files and the metadata corresponding to the material files uploaded by the material collector 4, the migration server 2 may poll the file directory of the FTP server 1 through a synchronous transmission tool according to a preset time period (such as 60 seconds, 90 seconds, etc.), compare the polling result of the current polling period with the polling result of the previous polling period, and further determine the content that the polling result of the current polling period is newly increased compared with the polling result of the previous polling period, where the newly increased content is the newly increased material files and metadata corresponding to the material files; the migration server 2 may copy the newly added material file and the metadata corresponding to the material file on the FTP server 1 to the local through an incremental copy manner.
By adopting the operation mode, incremental copying of the data is realized in a periodical polling mode, the problem of multiple copies of the same data can be avoided, the time consumed by copying the data is greatly reduced, and the return efficiency is further improved.
In order to further improve the efficiency of determining the entry address information corresponding to the metadata, the migration server 2 may be further configured to determine the entry address information corresponding to the metadata according to the data pre-stored in the relational database 21.
Specifically, the relational database 21 includes, in addition to the entry address information corresponding to the metadata, the content of a large amount of metadata written by the migration server 2; after the migration server 2 obtains the material files and metadata corresponding to the material files received by the FTP server 1, the key content (such as file name, file size, collection time, etc.) representing the material files may be used to traverse the relational database 21, so as to determine the entry address information corresponding to the metadata matched with the key content in the relational database 21.
By adopting the operation mode, the warehouse entry address information corresponding to the metadata can be determined only according to a small amount of data pre-stored in the relational database, so that the time consumed for determining the warehouse entry address information corresponding to the metadata is greatly reduced, and the feedback efficiency is further improved.
On the basis of the external photographing material real-time feedback system, in order to facilitate the related setting operation of material file feedback by material feedback personnel and obtain the feedback path of the material files, the embodiment of the invention also provides another external photographing material real-time feedback system. Referring to fig. 2, another structure diagram of the real-time feedback system of the external photographing material may further include a terminal device 5 (such as a mobile phone, a tablet computer, etc.) with a man-machine interaction function.
The terminal device 5 may be configured to obtain binding relationship data, and write the binding relationship data into a relationship database; wherein, the binding relationship data may include: the method comprises the following steps of associating relationship among user identity information, equipment information of a material collector and warehouse entry address information corresponding to material files.
Specifically, in the pre-building process of the relational database 21, the terminal device 5 may obtain user identity information (such as name, department, fingerprint feature, face feature, etc.), device information of the material collector (such as device ID, brand, model, etc.), and warehouse entry address information corresponding to the material file; and then binding the user identity information, the equipment information of the material collector and the warehouse entry address information corresponding to the material file together to form binding relation data. The specific presentation form (such as an array, a table, etc.) of the binding relationship data can be determined according to the actual needs, which is not limited. For example, the user identity information, the equipment information of the material collector and the storage address information corresponding to the material file are stored in the same data table, wherein the data table is the binding relation data, and the data table contains the association relation between the user identity information, the equipment information of the material collector and the storage address information corresponding to the material file. The three types of information may be manually input by the user through the terminal device 5, or may be identified by a sensor on the terminal device 5 (such as identifying a two-dimensional code, identifying a face, identifying a text, etc.), which may be specifically determined by itself according to actual needs, which is not limited.
Through the operation mode, binding relation data (including the association relation among user identity information, equipment information of the material collector and warehouse-in address information corresponding to the material files) is pre-stored in the relation database, and the migration server is used for storing the binding relation data. When the terminal equipment acquires any content in the user identity information, the equipment information of the material collector and the warehouse entry address information corresponding to the material file next time, the terminal equipment can directly determine the user identity information, the equipment information of the material collector and the warehouse entry address information corresponding to the material file according to binding relation data prestored in a relation database so as to further determine the warehouse entry condition of the material file.
In the pre-construction process of the relational database 21, for convenience of operation, the user identity information may be defined to include a first identity corresponding to a transmission person, a second identity corresponding to a producer, and token information corresponding to the producer; the terminal device 5 may be further configured to establish a first binding relationship between the first identity, the second identity and the token information, and write the first binding relationship into the relational database 21.
Through the operation mode, the relation type database is pre-stored with a first binding relation among the first identity mark, the second identity mark and the token information. When the terminal equipment acquires any content in the first identity mark, the second identity mark and the token information next time, related personnel (transmission personnel and production personnel) of the material files can be determined directly according to the first binding relation pre-stored in the relational database, and the related responsible persons can be determined in the returning and production process of the material.
In addition, in the pre-construction process of the relational database 21, for convenience of operation, the device information may be defined to include a device identifier; the terminal device 5 may be further configured to establish a second binding relationship between the device identifier and the identifier of the material file, and write the second binding relationship into the relational database.
In this way, the relational database is pre-stored with the second binding relation between the device identifier and the identifier of the material file. When the terminal equipment acquires any content in the equipment identifier and the identifier of the material file next time, the material file and the material acquisition equipment used for acquiring the material file can be directly determined according to the second binding relation pre-stored in the relational database, so that the initial source of the material file can be determined in the material acquisition process.
In the actual material returning process, in order to ensure the stability of material returning, the migration server 2 may be further configured to send a storage request to the repository server 3, and store the material file and metadata corresponding to the material file into a storage area corresponding to the storage address information in the repository server 3 after receiving a response message corresponding to the storage request.
In order to further avoid repeated transmission of the material files to the resource library, the migration server 2 may be further configured to poll the local file directory to determine the material files to be put in storage; and storing the material files to be put in storage and the metadata corresponding to the material files into a storage area corresponding to the put address information in the resource library server 3.
Specifically, the migration server 2 may traverse the local file directory on the migration server 2 by using a for search loop sentence to implement polling, and determine whether the material file is a material file that has been put in storage or a material file to be put in storage according to file information (such as file name, file size, file creation time, etc.) of the material file; if a certain material file is judged to be a material file to be put in storage, storing the material file and metadata corresponding to the material file into a storage area corresponding to the put address information in the resource library server 3; if a certain material file is judged to be the material file which is put in storage, no operation is executed.
For example, after storing a certain material file and metadata corresponding to the material file in a storage area corresponding to the storage address information in the repository server 3, the migration server 2 separately records file information (such as file name, file size, file creation time, etc.) of the material file for which the process has been completed in the relational database, so that the relational database can be traversed by the file information of the material file to determine whether the file information of the material file exists in the relational database; if yes (i.e. the file information of the material file exists in the relational database), the material file is the material file which is put in storage, and the migration server 2 does not execute any operation on the material file; if not (i.e. the file information of the material file does not exist in the relational database), the material file is indicated to be the material file to be put in storage, and the migration server 2 stores the material file and the metadata corresponding to the material file into a storage area corresponding to the put address information in the resource library server 3.
