Live Streaming Bit Rate Adjustment via Network Parameter Evaluation

The patent implements dynamic bit rate adjustment by introducing multiple adjustment ranges (first adjustment range, second adjustment range, etc.) that can be flexibly selected based on real-time network conditions. The system dynamically switches between different minimum bit rate values (r1min, r2min, etc.) according to network quality evaluations, making the bit rate configuration adaptive rather than static. This resolves the contradiction by allowing the system to maintain high bit rates for clarity when network is good, and switch to lower bit rates for smoothness when network deteriorates.

The patent changes the parameter of minimum bit rate from a fixed value to a variable that can take different values (r1min, r2min, r3min, etc.) corresponding to different adjustment ranges. By introducing parameter variability and establishing mapping relationships between network quality parameters and bit rate adjustment ranges, the system can optimize both viewing clarity and network adaptability under different operating conditions.

The system dynamically adjusts the minimum bit rate based on real-time network quality evaluation. When network conditions are poor, the system selects adjustment ranges with smaller minimum bit rates (r1min) to ensure smooth transmission. When network conditions improve, it switches to adjustment ranges with larger minimum bit rates (r2min, r3min, etc.) to enhance viewing clarity. This dynamic switching mechanism resolves the contradiction by adapting the bit rate to current network conditions.

The patent introduces multiple parameter values for minimum bit rate (r1min, r2min, r3min, etc.) corresponding to different adjustment ranges. By establishing a mapping relationship between network quality parameters and these bit rate parameters, the system can select the appropriate minimum bit rate parameter based on current network conditions, thus resolving the contradiction between adaptability and clarity.

The patent segments the bit rate adjustment process into multiple distinct adjustment ranges (first adjustment range, second adjustment range, third adjustment range, etc.), each with its own minimum and maximum bit rate values. This segmentation allows the system to evaluate network quality and select the appropriate adjustment range, thereby balancing smoothness and clarity based on current conditions rather than using a single fixed range.

The system dynamically selects which adjustment range to use based on real-time network quality evaluation. When network quality is poor, it selects adjustment ranges with larger ranges and smaller minimum bit rates to ensure smooth transmission. When network quality is good, it selects adjustment ranges with smaller ranges and larger minimum bit rates to ensure viewing clarity. This dynamic selection resolves the contradiction between smoothness and clarity.

The patent divides the overall bit rate adjustment into multiple segmented adjustment ranges, each optimized for specific network quality conditions. This segmentation enables the system to maintain a relatively small adjustment range (for clarity) when network conditions are good, while switching to a larger adjustment range (for adaptability) when network conditions are poor, thus resolving the contradiction in different operating scenarios.

The system changes the parameters of the adjustment range (minimum bit rate, maximum bit rate, and range size) based on network quality conditions. By establishing a mapping between network quality parameters and adjustment range parameters, the system can dynamically adjust the range size to balance clarity and adaptability requirements under different network conditions.
