Network Architecture and Compression Protocols of Walksnail Avatar HD Links
265 (HEVC) high-efficiency video coding, streaming 1080p resolution at 120 fps across selectable 20 MHz or 40 MHz RF channel widths. The underlying protocol incorporates dynamic adaptive bitrate throttling, continually profiling signal-to-noise ratios (SNR) and packet loss on the link.
When radio conditions degrade, the codec dynamically adapts quantization parameters, preserving critical video stream continuity without link dropouts.
