The invention relates to the field of
signal processing and intelligent detection, and particularly discloses an
HDMI signal intelligent detection and real-time
analysis method and
system. The method comprises the following steps of: extracting a key segment based on an
image frame, an audio frame and a control signaling
frame sequence, compressing and coding, and generating a
key frame index and an original feature mark; generating an abnormal index and a candidate error segment based on the jump and fluctuation characteristics; multi-
modal fusion analysis is executed, and a diagnosis result and a
modal feature vector are generated; constructing an equipment portrait based on the
modal features and historical equipment data, and extracting a detection parameter strategy; executing strategy optimization and
configuration analysis, generating control information and generating lightweight
model parameters in combination with equipment characteristics; and finally,
edge model parameter synchronization and detection behavior closed-
loop optimization are completed. Through the method and the device, high-precision real-time detection under resource constraint can be realized on the differentiated HDM I access equipment, the model deployment flexibility and the detection response efficiency are effectively improved, and the method and the device have relatively high
system adaptability and
engineering practical value.
