Content Playback Estimation via Dynamic Buffer Thresholds

The playback buffer amount is dynamically adjusted based on real-time network conditions and playback state. The buffer is increased when network fluctuation is detected and decreased when playback is stable, allowing the system to adapt to changing conditions rather than using a fixed buffer size. This resolves the contradiction by making the buffer size flexible rather than static.

The system changes the buffer parameter (buffer amount) based on detected playback halts and network conditions. When a playback halt is detected, the buffer amount is increased to prevent future halts. When playback is stable, the buffer amount is reduced to minimize start-up time. This dynamic parameter adjustment resolves the contradiction between reliability and time loss.

The buffer amount is dynamically adjusted based on detected playback halts and current network conditions. Rather than using a permanently large buffer, the system increases the buffer only when playback halts are detected or network fluctuation occurs, and reduces it when playback is stable. This resolves the contradiction by making buffer size adaptive rather than static.

The system automatically adjusts buffer size based on its own playback state and network conditions without requiring manual intervention or predetermined fixed settings. The buffer management is self-regulating, increasing when needed and decreasing when not needed, thus resolving the contradiction between continuity and response time.

The content data is segmented into chunks for organized buffer management, and the system tracks the reception status of each chunk individually. This segmentation allows precise determination of playback halt causes by analyzing which specific chunks are missing or delayed, resolving the contradiction between organizational simplicity and estimation accuracy.

The system replaces simple chunk-counting buffer management with a sophisticated analysis mechanism that examines packet reception timing, sequence numbers, and chunk completion status. This substitution of the estimation mechanism provides accurate playback halt detection while maintaining chunk-based organization, resolving the contradiction between ease of management and measurement precision.

The system uses packet capture data as an intermediary to indirectly estimate playback buffer status without modifying the terminal or distribution system. By analyzing packet reception timing, sequence numbers, and inter-arrival intervals from the network traffic, the system accurately infers buffer state and playback halt conditions while maintaining versatility across different applications. This intermediary approach resolves the contradiction between versatility and accuracy.

The system replaces direct terminal modification with indirect packet analysis. Instead of installing agents or modifying terminal software, the system captures and analyzes network packets to infer playback state. This substitution maintains versatility while achieving accurate estimation through sophisticated packet data analysis, resolving the contradiction between adaptability and precision.
