Image Frame Timeout Detection for Missing End Indications

The patent applies preliminary action by initiating a timer when the frame start indication is received, which will automatically expire after the expected receipt time of the frame end indication. This proactive timing mechanism prepares the system in advance to detect unbounded frames before they can cause hardware blocks to enter undefined states, thus maintaining reliability without adding complex reactive control logic

The patent implements feedback by monitoring whether the frame end indication is received before the timer expires. If the timer expires without receiving the frame end indication, the system detects an unbounded frame and triggers a reset operation. This closed-loop feedback mechanism ensures hardware block state stability by continuously monitoring frame reception status and taking corrective action when abnormalities are detected

The patent applies the taking out principle by extracting the problematic unbounded frame from the data stream when the timer expires. The system identifies the unbounded frame as invalid and initiates a reset operation that discards this corrupted frame data, thereby preventing it from causing further issues. This selective removal protects subsequent frames while accepting the loss of the current unbounded frame as a necessary trade-off for system reliability

The patent implements beforehand cushioning by establishing a timer mechanism that expires before the hardware blocks can enter undefined states. This timing buffer provides a safety margin that allows the system to detect and reset unbounded frames proactively, cushioning against potential data loss in subsequent frames. The timer creates a protective time window that prevents the propagation of errors

The patent applies preliminary action by pre-configuring the timer with the expected receipt time of the frame end indication when the frame start indication is received. This advance timing setup enables rapid detection of unbounded frames without requiring complex real-time analysis, thereby accelerating error recovery while using a relatively simple timer mechanism rather than elaborate monitoring systems

The patent implements self-service by using the timer mechanism to automatically detect and trigger reset operations for unbounded frames. The timer serves itself by expiring at the predetermined time and automatically initiating the error recovery process without requiring external intervention or complex decision-making logic. This self-service approach accelerates recovery while keeping the timing control system relatively simple
