[0029] Figure 11 is a flowchart of a bullet screen encoding method in an embodiment of the present application. The bullet screen encoding method can be applied to various application scenarios where repeated bullet screens appear, such as video platforms, and can improve the encoding compression rate in this specific application scenario. Figure 1 As shown, the bullet screen encoding method includes the following steps:

[0030] S10: Obtain information of characters to be encoded.

[0031] Among them, the character information to be encoded refers to the character information to be encoded. It can be understood that the content of a barrage can be composed of one or more character information. When the computer processes the barrage, it will first compress and encode the character information corresponding to the barrage and store it. When the character information needs to be displayed, the character information can be displayed by decompressing the corresponding code. In one embodiment, in a barrage scenario such as a video platform, the barrage server of the video platform will first receive the character information to be encoded, compress and decompress the character information to be encoded, and then output it on the barrage module of the video platform.

[0032] S20: Determine a coding mode for the character information to be encoded, wherein the coding mode includes a fusion mode, an index mode and a normal mode, wherein the fusion mode includes a preset number of fusion mode coding information, and there is a mapping relationship between the fusion mode coding information and the fusion mode character information.

[0033] In the present application, different from the traditional coding mode, a variety of different coding modes are set. Among them, these coding modes include fusion mode, index mode and regular mode, etc. The coding compression rate effect of each coding mode is different, among which the coding compression rate of the fusion mode is better, the index mode is second, and the regular mode is similar to or the same as the traditional coding mode. It can be understood that, different from the traditional coding mode, the characters to be encoded in the present application will give priority to the coding mode with high coding compression rate, and combine a variety of different coding modes to achieve coding, and complete the encoding of character information. In one embodiment, before encoding, the coding mode of the character information to be encoded will be determined first. Specifically, the fusion mode includes a preset number of fusion mode coding information, and there is a mapping relationship between the fusion mode coding information and the fusion mode character information. The fusion mode is a limited number of coding modes, and the fusion mode coding information is specifically mapped to the corresponding fusion mode character information. In this way, when encountering a scene where the barrage content is long and the barrage is often repeated, the fusion mode coding information is used to quickly encode the character information to be encoded, without repeatedly encoding one character at a time according to the traditional coding mode, which can greatly improve the coding efficiency. In one embodiment, for example, the fusion mode coding information is numbered 0-15, where each code corresponds to a fusion mode character information. When the fusion mode character information and the character information to be encoded are the same or similar, the content of the barrage can be quickly determined and the encoding compression can be quickly performed.

[0034] S30: Encode the character information to be encoded according to the encoding mode.

[0035] In one embodiment, the encoding of the character information to be encoded will make full use of the multiple encoding modes mentioned above. In an ideal case, the character information to be encoded can only be encoded using the encoding mode with the highest encoding compression rate; in other cases, the character information to be encoded can be encoded using a combination of a fusion mode, an index mode, and a regular mode. It can be understood that when the character information to be encoded satisfies the encoding mode that can adopt a higher encoding compression rate, the encoding mode with the highest encoding compression rate that can be adopted will be used as much as possible, thereby achieving a higher efficiency of barrage encoding efficiency.

[0036] S40: updating the fusion mode character information of the fusion mode according to the occurrence frequency of the character information to be encoded in the preset time period.

[0037] In one embodiment, the fusion mode coding information is fixed, but the fusion mode character information is non-fixed. Such a setting can realize flexible adjustment of character coding and improve the operability of coding character information. For example, the fusion mode coding information 0, 1, 2, 3 originally stores the corresponding fusion mode character information A, B, C, D respectively. After ten minutes, as the content of the video platform changes, the barrage sent by the video viewers changes, and the repetition of the content of the barrage E, F, C in a certain time interval is very high. In the next period of time, the expectation of the appearance of barrage E, F, C is relatively high. The original fusion mode character information is A, B, C, D, which can be changed to E, F, C, D, F, E, C, D, C, B, E, F and other different fusion mode character information. When a user initiates a barrage related to E, F, or C, the barrage server will quickly encode the barrage related to E, F, or C according to the updated fusion mode character information, which greatly improves the encoding compression rate of the barrage and effectively improves the flexibility and accuracy of encoding the character information to be encoded.

[0038] In steps S10-S40, a combination of multiple encoding modes such as fusion mode, index mode and normal mode is used to achieve fast encoding of the encoded character information. Compared with the traditional barrage encoding method, the barrage encoding method of the present application has a significant improvement in the encoding compression rate in scenarios where the barrage content is long and the barrage is often repeated. The encoding mode selection is also progressive, and a better encoding compression rate can still be achieved when the video content changes and multiple types of barrages are sent.

[0039] Furthermore, in step S20, i.e., the step of determining the encoding mode of the character information to be encoded, the following steps are specifically included:

[0040] S21: Searching the fusion mode character information to see whether there is character information matching the character information to be encoded; if so, determining to encode the successfully matched character information to be encoded in the fusion mode.

[0041] In one embodiment, ideally, the barrage content corresponding to the character information to be encoded has completely identical barrage content in the fusion mode character information. In this case, it is only necessary to encode according to the fusion mode encoding information corresponding to the fusion mode character information, which can significantly improve the encoding compression rate. Of course, in this application, as long as there is character information matching the character information to be encoded in the fusion mode character information, the fusion mode encoding information can also be used for encoding, but the fusion mode character information needs to be deleted so that the output barrage content is consistent with the content of the character information to be encoded input by the user.

[0042] S22: If not all the character information to be encoded is encoded in the fusion mode, the unencoded character information to be encoded is retrieved in the index table. If there is index coding information mapped to the unencoded character information to be encoded in the index table, the successfully retrieved unencoded character information to be encoded is determined to be encoded in the index mode, wherein the index table stores the mapping relationship between the index coding information and the index character information.

[0043] Among them, the coding compression rate of the index mode is a coding mode that is higher than the normal mode and lower than the fusion mode. Specifically, the normal mode may adopt a coding length of 16 bits, while the index mode may adopt a coding length of 12 bits or lower, and the fusion mode may adopt a coding length of 4 bits, 6 bits, etc. that is lower than the index mode. The implementation of the index mode is based on an index table, which stores a mapping relationship between an index number and character information, and the character information may be a single character or a combination of multiple characters. It can be understood that by establishing an index table, the character information to be encoded can be quickly encoded, and its coding compression rate will be greatly improved compared to the normal mode.

[0044] S23: If there is still some character information to be encoded that has not been encoded after adopting the fusion mode and the index mode, the remaining character information to be encoded is determined to be encoded in the normal mode.

[0045] In one embodiment, the conventional mode may be a traditional encoding mode. When the above multiple efficient encoding modes are not applicable, the basic conventional mode may be used to encode the character information to be encoded. In this way, the above encoding modes can be combined to ensure the accuracy of encoding compression while maximizing the encoding compression rate.

[0046] In steps S21-S23, the encoding of the encoded character information is achieved by combining the fusion mode, index mode and normal mode. During encoding, matching is performed in the order of fusion mode → index mode → normal mode, and the optimal encoding mode that meets the conditions is preferentially selected. It can be applied to different bullet screen scenarios, and the encoding compression rate is greatly improved while maintaining the accuracy of encoding compression.

[0047] Furthermore, the fusion mode includes a strong fusion mode and a weak fusion mode.

[0048] Among them, the strong fusion mode can be understood as a mode in which the character information to be encoded and the character information content of the fusion mode have a high degree of match, which can also be called the first fusion mode in this application; the weak fusion mode can be understood as a mode in which the character information to be encoded and the character information content of the fusion mode have a low degree of match, which can also be called the second fusion mode in this application.

[0049] Figure 2 Schematic diagram of a strong fusion mode in an embodiment of the present application. Figure 2 As shown, there are 16 fusion mode character information in total, among which, the character information to be encoded "Thank you teacher" and the first fusion mode character "Thank you teacher for your explanation" have 4 characters in common, which can be considered as a strong fusion mode.

[0050] Figure 3 Schematic diagram of a weak fusion mode in an embodiment of the present application. Figure 3 As shown, there are 16 fusion mode character information in total, among which the character information to be encoded "Thank you" and the first fusion mode character "Thank you teacher for your explanation" have only two characters in common, which can be considered as a weak fusion mode.

[0051] Further, in step S21, the step of searching whether there is character information matching the character information to be encoded from the fusion mode character information, and if there is, determining the character information to be encoded that successfully matches in the fusion mode to be encoded specifically includes the following steps:

[0052] S211: If the proportion of successfully matched character information to be encoded exceeds a preset ratio, the fusion mode is a strong fusion mode, and the character information that fails to match in the character information to be encoded is identified, so that the character information that fails to match is encoded using an index mode and / or a regular mode.

[0053] In one embodiment, when the fusion mode is a strong fusion mode, the successfully matched character information can be retained and the character information that failed to match can be identified. In the encoding stage, the successfully matched character information will be encoded according to the fusion mode encoding information, while other unmatched character information will be encoded using other encoding modes.

[0054] S212: If the proportion of successfully matched character information to be encoded does not exceed a preset ratio, the fusion mode is a weak fusion mode, and the weakly fused character information that has been successfully matched in the character information to be encoded is identified, or the weakly fused character information is determined by setting a fusion starting point and a fusion end point to encode the weakly fused character information.

[0055] In one embodiment, considering that the character information successfully matched by the weak fusion mode is scattered among the character information, which is not conducive to the encoding and decoding of the barrage content, if the encoding process is directly performed according to the fusion mode coding information, it will be more complicated and prone to errors. In this application, the weakly fused character information can be determined by setting the fusion starting point and the fusion ending point. The specific method is as follows: assuming that the number of characters in the fusion mode character information is 16, in order to maintain the continuity of the character information connection, the best coherence section in the successfully matched character information can be taken as the saved character information. For example, if the first and last characters of the fusion mode character information are successfully matched, and the middle 4 characters are also successfully matched, the position of the first character of the middle 4 characters can be used as the fusion starting point, and the position of the last character of the middle 4 characters can be used as the fusion ending point. In this way, without destroying the coherence and integrity of the characters, the content that can be encoded using the fusion mode coding information can be mined as much as possible in the weak fusion mode.

[0056] In steps S211-S212, a strong fusion mode and a weak fusion mode are provided to analyze different situations that may occur in actual applications, and better solutions are provided for each case, which can extract available information as much as possible in the strong fusion mode and the weak fusion mode to improve the coding compression rate.

[0057] Furthermore, the amount of fusion mode encoding information is 2 n , where n is a natural number and 2 n Do not exceed the preset quantity value.

[0058] In one embodiment, n is set to a coding length not exceeding the index mode. In practical applications, n can be set to 4, 5, 6, etc. When n is set to 4, the number of fusion mode coding information is 16 codes, and when n is set to 6, the number of fusion mode coding information is 64 codes. Users can set n according to the type of repeated bullet comments, and it is not limited here.

[0059] Furthermore, before step S10, that is, before obtaining the character information to be encoded, the method also includes the following steps: obtaining general scene character information; establishing a mapping relationship between the general scene character information and the index coding information to obtain a general index table; obtaining scene information; determining specific scene character information based on the scene information; establishing a mapping relationship between the specific scene character information and the index coding information to obtain a specific index table.

[0060] In one embodiment, the index table includes a general index table and a specific index table. General scenarios refer to scenarios that are generally summarized and summarized, while specific scenarios are scenarios specially formulated according to specific needs. In this application, the general index table and the specific index table cover most of the possible bullet screen speech scenarios. If the corresponding character information is not found in the fusion mode, most of them can be found in the index table. In addition, the index table itself also classifies various scenarios, which will be more efficient in searching for character information. The establishment of this index table can also improve the encoding compression rate compared to the traditional encoding method.

[0061] Furthermore, in step S40, that is, the step of updating the character information of the fusion mode according to the occurrence frequency of the character information to be encoded in the preset time period, the following steps are specifically included:

[0062] S41: within a preset time period, if the occurrence frequency of the character information to be encoded exceeds a first preset threshold, the fusion mode character information first stored in the fusion mode is obtained.

[0063] S42: Using the character information to be encoded to replace the first stored fusion mode character information, and establishing a mapping relationship with the corresponding fusion mode encoding information.

[0064] In steps S41-S42, the first-in-first-out method is adopted to realize the replacement of the character information to be encoded. According to the continuous changes in time and frequency, the fusion mode character information is also improved with time, which effectively improves the encoding compression rate. In the case of periodic changes in barrage, the encoding can be intelligently optimized, which plays a good transition role.

[0065] Furthermore, the method further comprises the following steps:

[0066] Within the preset time period, if the occurrence frequency of the character information to be encoded exceeds the first preset threshold, and the overlap between the character information to be encoded and the currently stored fusion mode character information exceeds the second preset threshold, the currently stored fusion mode character information is still retained.

[0067] In one embodiment, if the repetition between the character information to be encoded and the character information to be replaced is too high, in the multi-scenario application of the strong fusion mode and the weak fusion mode, the actual meaning of the replacement improvement is not great. At this time, the currently stored fusion mode character information can still be retained. This can also avoid invalid replacement work on the encoded character information, effectively saving system resources.

[0068] In an embodiment of the present application, first, the character information to be encoded is obtained, and the encoding mode of the character information to be encoded is determined, wherein the encoding mode includes a plurality of encoding modes that provide encoding support for the character information to be encoded, such as a fusion mode, an index mode, and a regular mode. Among them, the fusion mode includes a preset number of fusion mode encoding information, and there is a mapping relationship between the fusion mode encoding information and the fusion mode character information, which can use fewer storage resources to realize barrage encoding; after determining the encoding mode of the character information to be encoded, the character information to be encoded will be encoded according to the encoding mode to improve the compression rate of the barrage encoding, and the fusion mode character information of the fusion mode will be updated according to the frequency of occurrence of the character information to be encoded in a preset time period, thereby realizing the real-time update of the barrage, making it easier to determine repeated barrages as encoding modes with high encoding compression rates such as fusion modes. The present application can effectively improve the encoding compression rate and make better use of computer storage and computing resources.

[0069] Furthermore, the present application also combines the fusion mode, the index mode and the regular mode to realize the encoding of the character information to be encoded. When encoding, the matching is carried out in the order of fusion mode → index mode → regular mode, and the optimal encoding mode that meets the conditions is preferentially selected, which can be applicable to different bullet screen scenes, and on the basis of maintaining the accuracy of encoding compression, the encoding compression rate is improved; further, the present application also provides a strong fusion mode and a weak fusion mode to analyze different situations that may occur in actual applications, and provides a better solution for each case, which can extract the available information as much as possible in the strong fusion mode and the weak fusion mode to improve the encoding compression rate; further, the present application also establishes an index table, and the establishment of the index table can also improve the encoding compression rate compared with the traditional encoding method; further, the present application also adopts a first-in-first-out method to realize the replacement of the character information to be encoded. According to the continuous changes in time and frequency, the fusion mode character information also improves with time, which effectively improves the encoding compression rate. In the case of periodic replacement of bullet screens, the encoding can be intelligently optimized, which plays a good transition role; further, the present application can also avoid invalid replacement work for the encoded character information, and effectively save system resources.

[0070] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

If there is index coding information mapped to the unencoded character information to be encoded in the index table, the successfully retrieved unencoded character information to be encoded will be determined to be encoded in the index mode, wherein the index table stores the mapping relationship between the index coding information and the index character information.
