Multimedia communication service processing methods Technical Field

[0001] This invention relates to the field of communication service processing technology, and more particularly to a method for processing multimedia communication services. Background Technology

[0002] Multimedia communication services, as one of the core applications in the field of communication technology, widely cover diverse scenarios such as video conferencing, online live streaming, remote collaboration, and mobile multimedia on-demand. Their core objective is to achieve stable and efficient transmission of various multimedia information, including audio, video, and images, between different communication terminals and transmission networks, meeting users' needs for real-time, complete, and high-quality information interaction. With the rapid development of digital technology, the amount of multimedia information is exploding. During transmission, multiple key factors must be considered, including the differences in the real-time requirements of the multimedia information itself, the priority levels of different users, the integrity requirements of data transmission, and the load fluctuations of the communication path. These factors directly affect the user experience and transmission efficiency of communication services. Currently, multimedia communication services have been deeply integrated into multiple fields such as office work, entertainment, education, and healthcare, becoming a key support for ensuring efficient information flow and promoting the normalization of remote interaction. Their technological optimization and upgrades consistently revolve around core demands such as improving transmission speed, reducing packet loss rate, and ensuring content quality.

[0003] However, traditional multimedia communication service processing methods generally adopt a uniform compression ratio for multimedia data that needs to be compressed when dealing with high-load transmission scenarios. This fails to fully consider the differences in importance of different data content, resulting in the over-compression of core content with high quality requirements, such as video keyframes and audio core samples. This leads to problems such as blurry images and distorted sound, which seriously affects the user experience. Meanwhile, ordinary content with high redundancy still occupies a lot of transmission bandwidth due to insufficient compression, resulting in a waste of network resources. Ultimately, it is impossible to achieve an effective balance between improving transmission efficiency and ensuring content quality, making it difficult to adapt to complex and ever-changing multimedia communication scenarios and diverse user needs.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] As shown in Figure 1, the multimedia communication service processing method first obtains classification data of multimedia information through a communication database, analyzes and calculates it to obtain the priority transmission index of multimedia information, and divides multimedia information into priority transmission information and standard transmission information. The calculation process of the priority transmission index of multimedia information is as follows: S11, obtain classification data of multimedia information and analyze and calculate it. The classification data includes the real-time demand index A (value range 0-1, the larger the value, the higher the real-time demand), the user priority index B (value range 0-1, the larger the value, the higher the user priority), and the data integrity demand index C (value range 0-1, the larger the value, the higher the integrity demand). It should be noted that the real-time demand parameter is obtained by collecting multimedia data transmission scenarios (such as video conferencing, ordinary browsing) and uses, extracting latency thresholds and frame rate requirements, quantifying them, and normalizing them to the range of 0-1; the user priority parameter is based on the user's preset permissions and business level (such as speaker / (For ordinary users), quantify user priority and normalize it to the range of 0-1; data integrity requirement parameters are obtained by collecting data packet loss tolerance and restoration accuracy requirements, quantified and normalized to the range of 0-1; S12, calculate the priority transmission index of multimedia information according to the following formula. : in, The real-time demand index for multimedia information.

The preset priority weight coefficient, The priority transmission index of multimedia information is a preset integrity weighting coefficient. It is used to reflect the importance of priority transmission of multimedia information. The larger the priority transmission index, the higher the importance of priority transmission of multimedia information. The smaller the priority transmission index, the lower the importance of priority transmission of multimedia information.

[0018] The process of dividing multimedia information into priority transmission information and standard transmission information is as follows: S21, obtain the preset priority transmission threshold.

At the same time, the compression order of the standard transmission information is pre-ordered.

[0019] Then, through the communication database, the load data of the multimedia communication path is obtained, analyzed, and calculated to obtain the communication load index of the multimedia communication path, and the communication path is divided into high-load path and low-load path; the calculation process of the communication load index of the multimedia communication path is as follows: S31, Obtain the load data of the multimedia communication path and analyze and calculate it. The load data includes the amount of data transmitted by the multimedia communication path, bandwidth usage, and packet loss rate data; S32, Calculate the communication load index of the multimedia communication path according to the following formula. : in, This refers to the actual amount of data transmitted per unit of time through the multimedia communication path.

Communication load index of multimedia communication path Comparative analysis, when If the multimedia communication path is overloaded, the multimedia data compression program needs to be started. Based on the priority transmission index, multimedia information is compressed sequentially in ascending order. Simultaneously, the communication load index of the multimedia communication path is monitored in real time. When the communication load of the multimedia communication path is moderate or too light, the compression of multimedia data is stopped. S42, When If the multimedia communication path is at a certain level, it indicates that the communication load is moderate or too light, and there is no need to start the multimedia data compression program; the current multimedia information communication transmission status should continue.

[0021] Next, the multimedia information to be transmitted in the high-load path is compressed. The content data of the multimedia information to be transmitted is obtained through the communication database, analyzed, and calculated to obtain the importance index of the multimedia information content to be compressed. The multimedia information content to be compressed is then divided into high-compression content, standard-compression content, and low-compression content. The calculation process of the importance index of the multimedia information content to be compressed is as follows: S51, Obtain the content data of the multimedia information to be transmitted and analyze and calculate it. The content data includes the texture complexity feature value, color richness feature value, and motion vector feature value of the multimedia information content; S52, Calculate the importance index of the multimedia information content to be compressed according to the following formula. : in, The texture complexity feature value of multimedia information content.

The preset motion weight coefficients, and The content importance index of the multimedia information to be compressed is used to reflect the importance of the multimedia information content to be compressed. The higher the content importance index value, the higher the importance of the multimedia information content to be compressed, and the lower the content importance index value, the lower the importance of the multimedia information content to be compressed.

[0022] The process of dividing the multimedia information content to be compressed is as follows: S61, obtain the preset lower threshold of content importance. and content importance upper limit threshold Importance index of multimedia information content to be compressed Comparative analysis, when If the compression ratio is high, it indicates that the multimedia information to be compressed is of high importance and should be classified as low-compression content, thus requiring a reduction in the compression ratio; S62, when If the value is S63, it indicates that the multimedia information content to be compressed is of average importance and is classified as standard compression content, and compressed according to the preset standard compression ratio; If the compression ratio is too high, it indicates that the multimedia information to be compressed is of low importance and should be classified as high-compression content, thus requiring an increase in the compression ratio.

[0023] Finally, a preset standard compression ratio is obtained, and combined with the priority transmission index and content importance index, the compression ratio of the multimedia information to be compressed in the high-load path is adjusted, and the compressed multimedia information is transmitted through the transmission path. The process of adjusting the compression ratio of the multimedia information to be compressed in the high-load path is as follows: S71, Obtain the preset standard compression ratio, and combine it with the priority transmission index and content importance index; S72, Calculate the adjusted compression ratio according to the following formula: in, This is the adjusted compression ratio for highly compressed content. This is to adjust the compression ratio of the low-compression content. The preset standard compression ratio, The preset lower threshold for content importance. The preset upper limit threshold for content importance. The importance index of the multimedia information content to be compressed. As a priority transmission index for multimedia information, The preset adjustment coefficient is determined through a large amount of historical experimental data; S73, according to the adjusted compression ratio, a conventional multimedia compression algorithm (such as H.265 video compression algorithm, MP3 audio compression algorithm) is used to compress the high-compression content or low-compression content, and the compressed multimedia information is transmitted through the transmission path.

[0024] This invention acquires multimedia information classification data from a communication database and calculates a priority transmission index, dividing the information into priority transmission and standard transmission categories. This prioritizes the transmission of core information with high real-time requirements, user priority, and data integrity, while also rationally arranging the compression order to avoid over-compression of core information due to improper compression order, effectively solving the problem of compromised core content quality in traditional methods. Simultaneously, by acquiring communication path load data and calculating a communication load index, the compression program is initiated only when the path is under high load, maintaining normal transmission under low load, avoiding resource waste caused by indiscriminate compression and improving transmission resource utilization. Furthermore, by analyzing the content data of the multimedia information to be compressed and calculating a content importance index, the content is divided into different compression levels. Combined with the priority transmission index and a preset standard compression ratio, the compression ratio is dynamically adjusted, ensuring that high-importance content uses a low compression ratio to maintain quality, while low-importance content uses a high compression ratio to save bandwidth, achieving a precise match between content quality and transmission efficiency.

[0025] The size of the interval and threshold is set to facilitate comparison. The size of the threshold depends on the amount of sample data and the number of bases set by those skilled in the art for each set of sample data; as long as it does not affect the ratio between the parameter and the quantized value.
