This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for rendering delay aware packet pacing for real time multimedia applications. A processor of a first device transmits, to a second device, an indication of a processing delay associated with a set of packets associated with media content. The processor receives, from the second device, the set of packets in a packet arrival pattern that is based on the processing delay.

Techniques described herein are directed to determining that multimedia content displays a representation of an item offered for sale (1) at a first timestamp and (2) at a first location relative to a viewable window of a user device; generating an interactive element comprising an e-commerce tag interactable for purchase of the item; rendering, at the first timestamp, the interactive element on a first portion of the multimedia content and positioned relative to the representation of the item in a predetermined spatial configuration in the viewable window; rendering, at a second timestamp, the interactive element on a second portion of the multimedia content and positioned relative to the representation in the same spatial configuration; detecting an interaction with the interactive element; and based on detecting the interaction, displaying a graphical user interface configured to allow the user to purchase the item.

The present invention discloses a real-time multimedia message transmission method based on a 5G network, relates to the technical field of data transmission, and is used to improve the problem that some checksum algorithms cannot identify data duplication. The method comprises the following steps: detecting the transmission distance and the amount of transmitted data of a transmission channel, calculating the transmission data error rate by a grading method, and when the transmission data error rate is higher than a threshold, using a cumulative checksum algorithm to respectively calculate the checksum of the transmitted data when it is transmitted and received, and judging whether the transmission is erroneous by the checksum. When the checksum is consistent, obtaining the data source and data update frequency of the transmitted data, analyzing the degree of data duplication by fuzzy reasoning based on the data source and update frequency, and calculating the data duplication rate if the degree of data duplication is high. Different checksum algorithms are provided for users to choose according to the degree of data duplication, and judging whether a data duplication problem occurs according to the checksum algorithm. When the data is repeated, the data repetition rate is given to facilitate subsequent analysis and processing.

The present application relates to the field of signal processing technology, and in particular to a method and device for constructing a grid frequency reference signal network and positioning audio, wherein the method comprises: obtaining downsampled audio from online real-time multimedia data in multiple regions; processing the audio to obtain a grid frequency signal of a single audio when it is detected that the audio has a grid frequency; processing the grid frequency signals of multiple audios in the same region to obtain a single-region grid frequency reference signal, and processing the single-region grid frequency reference signals of multiple regions to obtain a grid frequency reference signal network; processing the audio to be located to obtain a grid frequency signal of the audio to be located and calculating the correlation coefficient between the grid frequency signal of the audio to be located and each node of the grid frequency reference signal network to obtain the final positioning result of the audio. The present application can realize grid frequency reference signal network construction and audio positioning based on online real-time multimedia data.

The present invention provides a real-time multimedia streaming transmission method in the field of multimedia streaming technology, including: step S10, the server calculates the playback expiration timestamp of the frame data of the first frame of the real-time multimedia after it arrives at the client; step S20, the server sends each frame data of the real-time multimedia to the client in sequence through QUIC datagrams, stores the sent QUIC datagrams in a retransmission buffer, updates the playback expiration timestamp and sequence number, and synchronizes the playback expiration timestamp to the client; step S30, the client feeds back a reception confirmation response to the server based on the received QUIC datagram, and the server deletes the corresponding QUIC datagram in the retransmission buffer based on the received reception confirmation response; step S40, the client performs validity verification on the missing frame data in the received QUIC datagram based on the playback expiration timestamp, and then plays the corresponding frame data. The advantages of the present invention are: greatly improving the reliability and real-time performance of real-time multimedia streaming transmission.
