The functions performed by the method may be performed by a processor in a first playback device, which comprises at least the processor and the storage medium, invoking program code, which of course may be stored in a computer storage medium.
Fig. 1 is a schematic implementation flow chart of a linking method of a playing device according to an embodiment of the present application, as shown in fig. 1, the method may include the following steps 101 to 103:
step 101, collecting play data of at least one first program.
In some embodiments, the first playback device includes a data acquisition module; the first playing device may collect the playing data of the at least one first program through the data collection module.
In some embodiments, the first playing device may automatically trigger the viewing data statistics program in the data acquisition module when playing the first program, where the viewing data statistics program records at least the playing data of the first program.
In some embodiments, the playing data of the first program includes at least one frame of playing image of the first program; the at least one frame of playing image can be a video frame image with or including key information selected from playing fragments of the first program; the key information may include a director of a man or woman, etc. The format of the play images in the data acquisition module can be bmp, jpg, png, or the like.
In some embodiments, the playback data of the first program further includes time location information of the at least one frame of playback image in the first program.
In some embodiments, the data collection module may also record program information for the first program based on the viewing data statistics program; the program information comprises program names, program time lengths, program staff members and the like.
In some embodiments, the data collection module may further record device information for the first playback device based on the viewing data statistics program; the device information includes a device type and a media access control address (Media Access Control Address, MAC) and the like; the device types comprise intelligent televisions, mobile phones, tablet computers, notebook computers, desktops and the like, and the device types can be used for knowing the program viewing paths of audiences; the MAC address may be used as a unique identifier for the first playback device.
In some embodiments, the first playing device further includes a storage module, and the playing data of the first program, the program information of the first program, and the device information of the first playing device collected by the data collection module may be used as viewing data information of the first program, where the storage module packages and compresses the viewing data information and stores the viewing data information.
Step 102, according to the play data, obtaining the reference data corresponding to the play data from the blockchain.
In some embodiments, the first playback device further comprises a data processing module. The storage module of the playing device marks the audience data information acquired by the data acquisition module as unprocessed data, sends the unprocessed data to the data processing module, requests the data processing module to process, and marks the audience data information processed by the data processing module as processed data.
In some embodiments, the data processing module hashes at least one frame of play image in the play data of the first program in the viewing data information to obtain at least one first hash value; the first playing device broadcasts the program name of the first program and the time position information of each playing image in the first program, and at least one third playing device on a request block chain provides the second hash value of the reference image corresponding to each playing image in the first program to the first playing device according to the broadcast content.
In some embodiments, the third playback device may be a playback device that plays back the first program on the blockchain, or may be another playback device that does not play back the first program on the blockchain, i.e., the third playback device may be any playback device on the blockchain. It can be understood that, after the first program is on-line on the relevant platform, any playback device on the blockchain has the authority to view and retrieve the first program, so that the third playback device can obtain the reference image corresponding to the playback image in the first program according to the program name of the first program broadcasted by the first playback device and the time position of each playback image in the first program, and then send the second hash value of each reference image to the first playback device.
In the embodiment of the present application, the hash algorithm used for performing the hash processing on the playing image may be an average hash algorithm, a perceptual hash algorithm, or a difference hash algorithm, which is not limited in the embodiment of the present application; after processing the playing image by using a hash algorithm, a binary value with a fixed length, namely a first hash value, can be obtained; the first hash value obtained according to the hash algorithm has uniqueness and unpredictability, and if the played image is changed or tampered, the generated hash value is far from the previous hash value, so that whether the played image is a tampered image can be judged relatively easily, and the accuracy of viewing data is ensured.
In some embodiments, the data processing module may determine the similarity of the playback image and the reference image according to the similarity of the first hash value and the second hash value.
As can be appreciated, after receiving the second hash value of the reference image sent by the at least one third playing device, the data processing module performs similarity calculation with the corresponding first hash value; for example, the data processing module may calculate the similarity between the first hash value and the second hash value according to the hamming distance calculation method, where the calculation method is as shown in the following formula (1):
Wherein d (x, y) represents the similarity between the ith playing image and the corresponding reference image; x [ i ] represents a first hash value of an ith play image; y [ i ] represents a second hash value of the reference image corresponding to the i-th play picture.
And step 103, adding the play data to the blockchain according to the DAG rule under the condition that the similarity between the play data and the reference data meets a first condition.
It can be appreciated that in the embodiment of the present application, the first playing device is directly added to the blockchain, and the miners are not required to package the playing data into blocks, and the blocks are added to the blockchain; the block chain of the embodiment of the application has no concept of 'blocks', and does not need miner packing, so that the handling cost is saved, and the data processing speed is improved.
In some embodiments, in a case that the similarity between the M frames of the play image and the corresponding reference image is greater than or equal to a first threshold, determining that the similarity between the play data and the reference data satisfies a first condition; wherein M is greater than or equal to 1 and less than or equal to the number of the played images, namely, M is greater than or equal to 1 and less than or equal to the number of the played images; the first threshold value can be preset according to actual requirements.
In some embodiments, if the similarity between the play data and the reference data meets a first condition, that is, when the similarity between the M-frame play image and the reference image corresponding to the M-frame play image is greater than or equal to a first threshold, requesting consensus verification from N second play devices on the blockchain; wherein N is greater than or equal to 1 and less than or equal to the number of playback devices on the blockchain; i.e., 1.ltoreq.N.ltoreq.the number of playback devices on the blockchain. And under the condition that the first playing device passes the common identification verification of the N second playing devices, connecting the first playing device with the N second playing devices according to a first direction.
In some embodiments, the first direction is from a first playback device to a second playback device.
In some embodiments, the data processing module notifies the in-link module of the first playing device to add the first playing device to the blockchain after confirming that the similarity between the playing data and the reference data meets the first condition, so as to avoid tampering of the viewing data in the first playing device when the viewing parameters are counted.
In some embodiments, before a first playing device to be first in-linked enters the chain, the blockchain comprises at least one creating playing device, when the first playing device is added to the blockchain, the first playing device performs consensus verification with part or all of the creating playing devices, and after the verification passes, the first playing device and the part or all of the creating playing devices are respectively connected in the same direction, namely, the first playing device enters the chain; when other subsequent first playing devices enter the chain, according to the same method, connecting the first playing device with N second playing devices on the block chain for common identification verification, wherein the second playing devices comprise creating playing devices; after the consensus verification is passed, the first playing device is respectively connected with the N second playing devices; wherein N is more than or equal to 1 and less than or equal to the number of playing devices on the blockchain, namely N second playing devices are part of playing devices on the blockchain; and the like, finally, each first playing device is chained into a chain to generate a blockchain with a DAG topological structure.
It should be noted that, in the embodiment of the present application, a playback device to be linked is referred to as a first playback device; after the first playing device enters the chain, the first playing device after entering the chain can be regarded as a second playing device on the block chain.
In the embodiment of the present application, the first playing device and N second playing devices on the blockchain are subjected to consensus verification, and after the consensus verification is passed, the first playing device is respectively connected with the corresponding N second playing devices, which may also be described as: the first playback device confirms the transaction with the N second playback devices. The embodiment of the present application is not limited thereto.
In some embodiments, when the first playback device is in-chain, the transaction may be confirmed with the first N second playback devices; fig. 2 is a schematic topological structure diagram of a DAG blockchain network according to an embodiment of the present application, as shown in fig. 3, when a first playback device 1 enters a chain, the first playback device 1 confirms a transaction with an originating playback device 1 and/or an originating playback device 2; when the first playing device 2 enters the chain, the first playing device 2 confirms the transaction with the creating playing device 2 and the first playing device node 1 after entering the chain; and by analogy, when the first playing device q enters the chain, the first playing device q and the first playing devices after the first two entering the chain confirm the transaction.
It will be appreciated that N is greater than or equal to 1 and less than the number of playback devices on the blockchain, i.e., the first playback device acknowledges the transaction with a portion of the playback devices on the blockchain when it enters the chain. Compared with the conventional blockchain, which needs to confirm transactions with all playing devices on the blockchain, the method improves the in-chain speed of the first playing device.
In other embodiments, the first playback device may acknowledge the transaction with any N second playback devices on the blockchain when it comes in-chain; fig. 3 is a schematic diagram of a topology of yet another DAG blockchain network according to an embodiment of the present application; when the first playing device 1 is in chain, the first playing device 1 can confirm the transaction with the creating playing device 1 and/or the creating playing device 2; when the first playing device 2 is in-chain, the first playing device 2 can confirm the transaction with the originating playing device 2 and the playing device node 1; when the first playing device 3 is in-chain, the first playing device 3 can confirm the transaction … with the originating playing device 1; and by analogy, confirming the transaction between the rest first playing devices and N arbitrary second playing devices corresponding to the rest first playing devices respectively, and generating a blockchain with a DAG topological structure.
It will be appreciated that in the above example, since the first playback device can confirm transactions with any N second playback devices, there is no need to confirm transactions in the in-chain order and the first N in-chain playback devices; therefore, a plurality of first playback devices can be supported to simultaneously and concurrently confirm transactions with N arbitrary second playback devices corresponding thereto. I.e. the playback device 1 acknowledges the transaction with the originating playback device and/or the originating playback device 2 and the playback device 3 acknowledges the transaction with the originating playback device 1 can be performed simultaneously, thus increasing the in-link speed of the first playback device.
In the embodiment of the present application, the playing device may also be described as a playing device node, and the originating device may also be described as an originating device node, an originating node, etc., which is not limited in this embodiment of the present application.
An embodiment of the present application provides a viewing statistics method, applied to an electronic device, and fig. 4 is a schematic diagram of an implementation flow of the viewing statistics method provided by the embodiment of the present application, as shown in fig. 4, where the method includes steps 401 to 403:
step 401, determining a fourth playing device on the pre-generated blockchain, which has played the first program; the topological structure of the blockchain is a DAG, and the nodes of the DAG at least comprise the fourth playing device;
Step 402, obtaining playing data of the first program recorded by the fourth playing device;
step 403, counting viewing parameters of the first program at least according to the playing data of the first program.
In some embodiments, the viewing parameters may include a rating and/or a click through rate. The viewing parameter of the first program during a time period may be determined based on a ratio of a number of fourth playback devices that played the first program over the blockchain over the time period to a number of all playback devices. The duration of the time period is not limited in the embodiment of the application.
It will be appreciated that the blockchain used to make the audience statistics is generated based on directed acyclic graph rules, thus increasing the transaction speed of the blockchain used to make the audience statistics and thus increasing the audience statistics speed.
Viewing data statistics refers to statistics of the audience rating or click rate of video programs, which refers to the percentage of the total number of viewers that watch a certain program in a period of time. In different market segments such as traditional digital televisions, internet broadband televisions, video websites and the like, audience rating and click rate are main indexes for evaluating program production effects and popularity, and are important references for program production, arrangement and adjustment.
Related audience data statistics methods, such as diary card method and measuring instrument method, are to select sampling users from small-scale samples, to collect audience data by manual recording audience information or by observation instrument, and to report to server for processing at preset time through telephone or broadband network. With the development of the blockchain technology, the characteristic that the blockchain cannot be tampered is also applied to the audience rating statistical method so as to improve the accuracy of audience ratings.
In the related audience data statistics method, the problems of limited number of covered samples, high data statistics cost, easy falsification of the counted data, low data accuracy and the like exist.
In some embodiments, a chain-based audience share statistics method employs a chain-based public blockchain. The method has the problems of low processing speed, high cost and the like, and particularly, along with the burst of the current massive short video content, how to accelerate the data processing speed and reduce the data processing cost is a new subject for viewing data statistics on the premise that the statistical sample size is not limited and the statistical data is not easy to tamper.
The embodiment of the application provides a viewing data statistics method and a viewing data statistics system based on a directed acyclic graph, which solve the problems in the viewing data statistics process by utilizing the characteristics of high processing speed, strong expansibility and high safety of the directed acyclic graph.
Video programs such as broadcast digital television, internet broadband television, mobile phone short video and the like show a hundred flowers and a complete state, and the quality of the video program production determines the popularity of the program. In some embodiments, a plurality of playing device nodes exist in a directed acyclic graph block chain, and the playing device nodes can form a directed acyclic graph block chain topological structure, and each playing device node at least comprises a data acquisition module, a data storage module, a data processing module and a link entering module, and is respectively responsible for acquiring, storing, processing and linking the playing device.
Based on this, an exemplary application of the embodiment of the present application in one practical application scenario will be described below.
Fig. 5 is a schematic view of viewing data information provided in an embodiment of the present application, where as shown in fig. 5, a data acquisition module obtains device information of a first playback device, where the device information includes a device type and a MAC address, a timestamp of each first program, and program information of the first program. The program information contains the program name, the program duration, the program author (an example of a staff member) and key video frame fragments of the program, wherein the video frame fragments are saved in the form of pictures.
In some embodiments, the data collection module stores the viewing data information in the data storage module after it has been collected.
In some embodiments, the data processing module is responsible for processing the viewing data of the first program, and determining whether the viewing data meets the statistical requirement according to a preset condition;
