2results about How to "Reduce bandwidth overhead" patented technology

This invention relates to the field of game anti-cheating technology, specifically to an AI-driven system for identifying and transmitting images of game violations. The system first aggregates authoritative game data on the server side, calculates the balance deviation score of attack attempts, filters high-risk triggering events, and limits the evidence collection time window and pixel acquisition area. Next, it extracts legitimate semantic summaries from the game engine rendering chain, generates a predictive structure mask, and identifies semantically uninterpretable illegal overlays by comparing pixel-level differences. Finally, it integrates risk-graded transmitted evidence, and the server completes consistency verification through a homogeneous process. This invention does not rely on the appearance characteristics of cheats, significantly reduces computing power and bandwidth consumption, and provides a complete and auditable evidence chain.

The invention provides a self-adaptive forward error correction method for a real-time audio and video stream transmission process, which can dynamically adjust error correction redundancy configuration according to the change of network packet loss characteristics so as to improve the data transmission reliability in a complex network environment. Specifically, in a real-time transmission process, a sending end carries out long-term trend estimation and short-time burst estimation on network packet loss by respectively adopting a Kalman filtering algorithm and an exponential weighted moving average algorithm based on a packet loss rate measurement value fed back by a receiving end, and a dual-time-scale packet loss prediction model is constructed. Meanwhile, the statistical fluctuation characteristics of the historical packet loss rate are calculated, a dynamic safety redundancy boundary is introduced, and the redundancy adjustment process is smoothed in combination with a hysteresis state control mechanism, so that frequent fluctuation is avoided. The method can reduce the redundancy overhead, improve the error correction capability and reduce the packet loss rate in a complex and changeable network environment, is suitable for real-time audio and video stream transmission under various network conditions, and has good practicability and robustness.
