The application provides an 8K high code rate panoramic live broadcast grading distribution method for a sports event private network, and belongs to the technical field of live broadcast distribution.The original 8K panoramic video is compressed and encoded by a high-efficiency video coding standard to generate a high code rate video stream in a live source node, and the high code rate video stream is pushed to a first forwarding node through a real-time transmission protocol.The maximum transmission unit of the private network full link is uniformly configured as 9000 bytes in the first forwarding node, and a data plane development kit user state protocol stack is enabled.A second distribution node concurrently pushes the high code rate video stream to terminal equipment through a lock-free ring buffer.A fault detection module combines active heartbeat detection with passive response time monitoring to monitor the node state in real time, and migrates the affected terminal to a backup node within a second, thereby solving the technical problems of high transmission delay and poor concurrent stability of the high code rate video stream during the grading distribution of the 8K high code rate panoramic video of the sports event private network.

This document provides a Real-Time Transport Protocol (RTP) sender for wireless communication, the RTP sender comprising: at least one memory; and at least one processor coupled to and arranged such that the RTP sender: receives a Protocol Data Unit (PDU) set size threshold, the PDU set size threshold determining the PDU set size flow characteristics of a service data stream; applies the PDU set size threshold to the PDU sets of the service data stream, the application including identifying a PDU set size change between a first PDU set and a second PDU set in the PDU sets of the service data stream, wherein the size of the second PDU set satisfies the PDU set size threshold; and transmits the first PDU set, the second PDU set, and an indication of the dynamic PDU set size change.

Embodiments of the present application disclose a data processing method and device, and a computer readable storage medium. A unified platform sends corresponding voice prompt information to a mobile terminal in response to a data processing request sent by the mobile terminal based on a session initiation protocol (SIP). The data processing request carries a target IMS account and an identification code of the mobile terminal. The target media terminal identification code sent by the mobile terminal based on the voice prompt information is received. If the identification code of the target mobile terminal obtained based on the target IMS account and the target media terminal identification code is equal to the identification code of the mobile terminal, a data viewing request is sent to the target media terminal according to the target IMS account and the target media terminal identification code. Media data collected by the target media terminal in response to the data viewing request is received, and the media data is sent to the mobile terminal based on a real-time transport protocol (RTP). The media data can be viewed through the data processing request, which has strong universality and improves security.
