Continuous Keyframe-Free Holographic Compression for Real-Time Audio-Video Streaming over Ultra-Low Bandwidth 2G Networks

Key Points

The aim is to develop a real-time audio-video streaming system that performs well in low-bandwidth conditions.
Utilized a continuous holographic compression model based on high-dimensional geometric embedding and adaptive multi-view projection.
Eliminated keyframes previously necessary for predictive codecs.
Assessed streaming performance over genuine 2G GSM - EDGE networks (9–200 kbps).
Achieved stable resolution of 640×480 at frame rates of 10/25 fps with synchronized audio.
Demonstrated resilience to packet loss and bandwidth degradation, unlike previous codecs which would freeze or collapse.
Showed that Forward Error Correction (FEC) is not needed and may reduce effective quality.

Abstract

This paper presents a real-time audio-video streaming system capable of delivering stable 640×480 resolution at 10/25 fps with synchronized audio over genuine 2G GSM - EDGE networks (9–200 kbps, high packet loss, high latency). The proposed method departs from conventional predictive codecs by eliminating keyframes entirely and introducing a continuous holographic compression model based on high-dimensional geometric embedding, adaptive multi-view projection, and sparse reconstruction. The system exhibits intrinsic resilience to packet loss and bandwidth degradation, achieving graceful quality scaling instead of freezing or collapse. Experimental observations further indicate that Forward Error Correction (FEC) is unnecessary and may reduce effective quality in this regime.
