Adaptive Video Compression Circuit System for Scene Complexity

The patent implements dynamic adjustment of the quantization table scale based on the complexity degree of video frames. The system transitions from a fixed compression rate to a dynamic one by calculating complexity metrics (such as variance of gradient modulus) for each frame and adjusting the quantization scale accordingly. This allows the compression rate to adapt to scene complexity while maintaining manageable computational complexity through efficient algorithms.

The patent changes the parameter of quantization table scale dynamically based on frame complexity. By modifying this key parameter according to calculated complexity degrees, the system achieves adaptability to different scenes without requiring complex computational structures. The complexity degree itself becomes a controllable parameter that drives the adjustment of compression settings.

The patent applies different compression rates to different frames based on their individual complexity characteristics. Simple frames receive higher compression rates (larger quantization scale) while complex frames receive lower compression rates (smaller quantization scale). This localized quality adjustment ensures optimal bandwidth utilization without sacrificing video definition where it matters most.

The system applies compression selectively based on frame complexity. For simple frames, it applies stronger compression (excessive action relative to complexity) to maximize bandwidth utilization. For complex frames, it applies milder compression to preserve quality. This partial application of compression strength prevents overall quality degradation while maintaining good bandwidth utilization.

The patent maintains high video quality selectively for complex frames by applying lower compression rates only where needed. For simple frames, it uses higher compression rates to reduce bandwidth consumption. This localized quality preservation ensures that bandwidth-critical complex scenes maintain definition while overall bandwidth usage is optimized across the entire video sequence.

The system applies mild compression (partial action) only to complex frames where quality preservation is critical, while applying stronger compression to simple frames. This selective approach prevents bandwidth exhaustion and frame loss in complex scenes without unnecessarily compromising quality in simple scenes, achieving an optimal balance between quality and bandwidth consumption.
