AI Technical Summary

Technical Problem

The existing MCX video transmission architecture relies heavily on software encoding and decoding, resulting in high latency, high power consumption, and performance degradation in weak networks. It lacks deep collaboration between hardware encoding and decoding and network transmission, and cannot intelligently schedule resources based on the real-time status of the device and business needs.

Method used

A three-tier architecture of application layer-SDK layer-hardware layer is constructed. Through video hardware encoding and decoding and RTP cross-layer collaborative transmission method, the entire link optimization from video frame processing and bitstream transmission to network adaptation is realized. This includes video acquisition and hardware encoding passthrough, adaptive RTP encapsulation, network transmission, reception and fast RTP reassembly, bitstream passthrough and hardware decoding, combined with intelligent scheduler for resource coordination.

Benefits of technology

Significantly improves system performance, reduces CPU utilization, decreases end-to-end latency, enhances network adaptability and transmission reliability, achieves intelligent balance between power consumption and resources, and builds an efficient, low-latency video transmission system.

Abstract

The invention discloses an MCX client video hard coding and decoding and RTP cross-layer cooperative transmission method, and belongs to the technical field of radio communication, in the method, an SDK layer is constructed between an application layer and a hardware layer, the SDK layer comprises a video hard coding and decoding channel and a network transmission straight-through channel, and the method comprises the specific steps of S1, video acquisition and hard coding straight-through; s2, carrying out code stream capturing and self-adaptive RTP (Real-time Transport Protocol) packaging; s3, network sending; s4, receiving and fast RTP recombination are carried out; s5, carrying out code stream direct connection and hard decoding; s6, performing low-delay rendering; the invention provides a'application layer-SDK layer-hardware layer 'three-level soft-hard combination architecture, a full-link optimized technical closed loop is formed by constructing a'video acquisition-hard coding and decoding-RTP transmission' straight-through channel and combining adaptive network scheduling and cross-layer resource collaboration, deep coupling of hardware coding and decoding capability and network transmission is realized, and the real-time performance of the system is improved. And the limitation of a traditional separated framework is fundamentally changed.
