A video stream processor with an adjustable clock frequency is used, dynamically changing its speed based on the selected data stream's communicated rate, allowing for efficient processing and power management across multiple tuners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the processor operates at maximum speed to handle peak data rates, then processing capability is sufficient for all data rates, but power consumption is excessively high when data rates are low
Solution Approach 1:
The processor dynamically adjusts its operating speed based on the actual data rate being processed. When data rates are low, the processor operates at reduced speed to save power. When data rates increase, the processor accelerates to maintain processing capability. This dynamic adaptation resolves the contradiction between maintaining sufficient processing capability and reducing power consumption during channel surfing activities.
Solution Approach 2:
The system changes the operating parameters of the processor (clock frequency/speed) according to the data rate requirements. By monitoring the data rate and adjusting the processor speed parameter accordingly, the system achieves optimal balance between processing capability and power consumption across varying data rate conditions.
2Adaptability or versatility
If the processor operates at maximum speed, then all data rates can be handled, but system power usage is greater than necessary for low-speed data rates
Solution Approach 1:
The processor transitions from static maximum-speed operation to dynamic speed adjustment. The system continuously adapts the processor speed to match the current data rate requirements, maintaining full adaptability to handle any data rate while minimizing energy loss by avoiding unnecessary high-speed operation during low-data-rate periods.
Solution Approach 2:
The patent converts the previously harmful effect of excessive power consumption into a beneficial feature by implementing speed modulation. The ability to vary processor speed allows the system to maintain versatility in handling different data rates while transforming the energy loss problem into an energy efficiency solution.
3Device complexity
If a single processor handles multiple tuners with different data rates, then device complexity is reduced, but the processor must operate at maximum speed to accommodate the highest data rate
Solution Approach 1:
A single processor is designed to handle multiple tuners with different data rates through dynamic speed adjustment. The processor universally serves multiple functions by adapting its operating speed to match the specific data rate requirements of each tuner, reducing device complexity while avoiding excessive power consumption through intelligent speed modulation.
Solution Approach 2:
The single processor dynamically adjusts its speed to accommodate different data rate requirements of multiple tuners. This dynamic capability allows one processor to replace multiple fixed-speed processors, reducing device complexity while minimizing power consumption by operating at the minimum necessary speed for each specific data rate.
