Dynamic Internal Bit Depth Adjustment in Video Decoding

The patent implements dynamic bit depth adjustment where the internal processing bit depth can be changed based on the content requirements. The system switches between 8-bit and 10-bit internal data modes dynamically, using 10-bit only when necessary for high-precision requirements and 8-bit for standard content to maintain high processing speed. This is achieved through configurable parameters that allow the codec to adapt its internal precision on-the-fly.

The patent applies different bit depths to different processing contexts and modules within the codec. Instead of uniformly using 10-bit throughout the entire system, it selectively applies higher precision only to specific modules or processing stages where it is truly needed, while using 8-bit for other portions. This localized approach to precision optimization balances quality requirements with processing efficiency.

The patent implements dynamic adjustment of internal buffer bit depths based on the actual coding requirements. The system can switch between 8-bit and 10-bit buffer configurations, allocating higher precision memory resources only when the content demands improved coding gain. This dynamic resource allocation optimizes the balance between coding performance and memory bandwidth consumption.

The patent applies different internal bit depths to different modules and buffers within the codec architecture. Instead of uniformly increasing memory bandwidth capacity throughout the system, it selectively enhances precision in specific modules where coding gain is most beneficial, while maintaining standard precision in other areas. This modular approach to precision optimization reduces overall memory bandwidth requirements while preserving essential coding quality.

The patent implements a dynamically configurable bit depth architecture where the internal processing precision and buffer sizes can be adjusted based on operational requirements. The system can transition between 8-bit and 10-bit modes, adapting its complexity level to match the task at hand. This dynamic complexity management allows the device to maintain high precision when needed while reducing resource consumption during standard operations.

The patent applies increased precision selectively to specific processing modules and buffers rather than uniformly throughout the entire system. By identifying and enhancing only the critical paths where higher bit depth provides measurable benefit, the patent avoids the proportional increase in overall device complexity that would result from system-wide precision enhancement. This targeted approach maintains essential processing quality while minimizing additional hardware requirements.
